Here, we compiled 11 regional series spanning from the early 15th century to 1988. We detrended the data to adjust for long-term biases such as warfare-related population decline. The homogenised regional series were subsequently merged into three supra-regional series: (1) the Mosel series, starting in 1416 and consisting of data from the former city-republic of Metz (France) and the Grand Duchy of Luxembourg; (2) the series for Germany, starting in 1511 and mainly originating from the former city-state of Heilbronn; and (3) the third series, starting in 1529 and representing production on the Swiss Plateau. The residuals of the supra-regional yield series were averaged, divided into seven classes, and multiplied by five quality classes. Yield quality indices (YQI) varying between 35 (large and excellent) and 1 (small and undrinkable) significantly correlated with temperatures between May and July. Regression analysis of the composite series revealed that yield and quality primarily depend on the climate conditions from May to July as well as on those in June of the previous year. Crops with a YQI > 28 (rated “good” by traditional winegrowers) were related to above-average May–July temperatures, early grape harvest dates and high tree-ring maximum latewood density values resulting from frequent anticyclonic weather situations. Crops with YQI > 10 could not be uncritically assigned to cold summers since severe winter conditions, and spring frosts sometimes substantially reduced yields without affecting quality, particularly during the Little Ice Age in the marginal Mosel and German areas. Extreme yield fluctuations challenged winegrowing communities. Overproduction induced wastefulness, while crop failures sometimes triggered witch hunts.\n\n【摘要翻译】本文探讨了关于中欧葡萄酒生产的叙事文献记录在多大程度上可以作为夏季气温的代表。在本文中，我们编制了 11 个跨越 15 世纪初至 1988 年的区域系列。我们对数据进行了去趋势化处理，以适应长期偏差，如与战争相关的人口下降。随后，这些均质化的区域系列被合并为三个超区域系列:(1) 摩泽尔系列，始于 1416 年，包括来自前城市共和国梅斯 (法国) 和卢森堡大公国的数据;(2) 德国系列，始于 1511 年，主要来自前城市国家海尔布隆;(3) 第三个系列，始于 1529 年，代表瑞士高原的生产。对超区域产量序列的残差进行平均，划分为 7 个类别，并乘以 5 个质量类别。产量质量指数 (YQI) 在 35(大且优质) 和 1(小且不可饮用) 之间变化，与 5 月至 7 月间的气温显著相关。对复合系列的回归分析显示，产量和品质主要取决于 5 月至 7 月的气候条件以及前一年 6 月的气候条件。YQI > 28 的作物 (被传统葡萄种植者评为 “优质”) 与 5 月至 7 月的平均气温以上、葡萄收获日期提前以及由于频繁的反气旋天气情况导致的树木年轮最大晚熟林密度值较高有关。由于冬季条件严酷，YQI > 10 的作物不能无条件地归因于寒冷的夏季，而春季霜冻有时会显著降低产量，但不影响品质，特别是在摩泽尔和德国边缘地区的小冰期期间。极端的产量波动对葡萄种植社区构成了挑战。过度生产导致浪费，而作物歉收有时会引发猎巫行动。", "publicationTitle": "Climate of the Past", "publisher": "Copernicus GmbH", "place": "", "date": "2026-03-06", "volume": "22", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "541-559", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.5194/cp-22-541-2026", "citationKey": "Pfister2026", "url": "https://cp.copernicus.org/articles/22/541/2026/", "accessDate": "2026-03-09T10:25:57Z", "PMID": "", "PMCID": "", "ISSN": "1814-9324", "archive": "", "archiveLocation": "", "shortTitle": "葡萄酒必须成为中欧 5 月至 7 月气候的指标，1416 年至 1988 年", "language": "en", "libraryCatalog": "Copernicus Online Journals", "callNumber": "2", "rights": "", "extra": "🏷️ /unread、Little Ice Age、summer temperature、grape harvest、central Europe", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Little Ice Age" }, { "tag": "central Europe" }, { "tag": "grape harvest" }, { "tag": "summer temperature" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T10:27:24Z", "dateModified": "2026-04-05T11:03:29Z" } }, { "key": "CS5B6EFJ", "version": 12184, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/CS5B6EFJ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/CS5B6EFJ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Stridbeck et al.", "parsedDate": "2026-03-04", "numChildren": 0 }, "data": { "key": "CS5B6EFJ", "version": 12184, "itemType": "journalArticle", "title": "Seven centuries of rainfall reconstructed from Scots Pine ring width in sub-Arctic Sweden", "creators": [ { "creatorType": "author", "firstName": "Petter", "lastName": "Stridbeck" }, { "creatorType": "author", "firstName": "Jesper", "lastName": "Björklund" }, { "creatorType": "author", "firstName": "Fredrik Charpentier", "lastName": "Ljungqvist" }, { "creatorType": "author", "firstName": "Jennie", "lastName": "Sandström" }, { "creatorType": "author", "firstName": "Mauricio", "lastName": "Fuentes" }, { "creatorType": "author", "firstName": "Paul J.", "lastName": "Krusic" }, { "creatorType": "author", "firstName": "Zhi-Bo", "lastName": "Li" }, { "creatorType": "author", "firstName": "Kristina", "lastName": "Seftigen" } ], "abstractNote": "As the sub-Arctic and Arctic regions undergoes rapid changes, understanding its hydroclimate history is more critical than ever. A limited availability of moisture-sensitive proxy data severely constrains our insights, underscoring the urgent need for more hydroclimate reconstructions in the region. Here we present a May–June precipitation reconstruction based on ring width from living and dead trees of Scots pine (Pinus sylvestris L.) growing under drought-stressed conditions at 63° N, near Skuleskogen National Park, on the northern part of the east coast of Sweden. The oldest deadwood sample dates back to the mid-11th century, and the Expressed Population Signal (EPS) exceeds 0.85 from 1320 CE until the present (2021 CE), making this the longest tree-ring-based hydroclimate reconstruction from high-latitude Fennoscandia. Unlike typical high-latitude forests in Fennoscandia, the trees at this site thrive under low-pressure conditions and show strong correlations up to approximately |r|=0.6 over the period 1920–2021 with drought-related variables such as precipitation, cloud cover, solar radiation, potential evapotranspiration and diurnal temperature range. The climate signal is concentrated to a short window between mid-May and early July but reflects climatic conditions over a broad region. Significant spatial correlations extend over most of Sweden as well as large parts of Norway and Finland, indicating sensitivity to large-scale climate systems. The tree-ring chronology also shows clear cyclic patterns, with a particularly strong ∼ 64-year cycle. The modern era stands out for its variability, with 2018 CE emerging as one of the of the driest year in the entire record. There is potential to extend the chronology further back in time, possibly to 1000 CE or earlier, and to extract additional climate information using other tree-ring parameters such as blue intensity.\n\n【摘要翻译】随着亚北极和北极地区的快速变化，了解其水文气候历史比以往任何时候都更加关键。水分敏感代理数据的有限可用性严重限制了我们的洞察力，凸显了该地区进行更多水文气候重建的迫切需求。在这里，我们提供了一个基于苏格兰赤松 (Pinus sylvestris L.) 活树和枯树年轮宽度的 5-6 月降水重建数据，这些树木生长在瑞典东海岸北部斯卡鲁斯科根国家公园附近北纬 63°的干旱胁迫条件下。最古老的枯木样本可以追溯到 11 世纪中叶，表达人口信号 (EPS) 大于 0。从公元 1320 年到现在 (2021 年) 共 85 年，这是高纬度费诺斯坎迪亚地区最长的基于树木年轮的水文气候重建时间。与芬诺斯坎迪亚典型的高纬度森林不同，这里的树木在低压条件下茁壮成长，并在 1920-2021 年期间与降水、云层覆盖、太阳辐射、潜在蒸发散和日间温度范围等干旱相关变量表现出强烈的相关性，约为 |r|=0.6。气候信号集中在 5 月中旬至 7 月初的短暂窗口期内，但反映了广泛区域的气候状况。显著的空间相关性覆盖了瑞典的大部分地区以及挪威和芬兰的大部分地区，表明对大规模气候系统的敏感性。树木年轮年代学也显示出明显的循环模式，其中约 64 年的周期特别强烈。现代时期以其多变性而闻名，2018 年被认为是整个历史上最干燥的年份之一。有可能将年表进一步向前推进，可能推到公元 1000 年或更早，并利用其他树轮参数 (如蓝色强度) 提取额外的气候信息。", "publicationTitle": "Climate of the Past", "publisher": "Copernicus GmbH", "place": "", "date": "2026-03-04", "volume": "22", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "461-481", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.5194/cp-22-461-2026", "citationKey": "Stridbeck2026", "url": "https://cp.copernicus.org/articles/22/461/2026/", "accessDate": "2026-03-09T06:49:27Z", "PMID": "", "PMCID": "", "ISSN": "1814-9324", "archive": "", "archiveLocation": "", "shortTitle": "根据瑞典亚北极圈苏格兰松环宽度重建的七个世纪降雨量", "language": "en", "libraryCatalog": "3.2 (Q2)", "callNumber": "2", "rights": "", "extra": "🏷️ /unread、precipitation、tree rings、ring width、Sweden、northern Europe", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Sweden" }, { "tag": "northern Europe" }, { "tag": "precipitation" }, { "tag": "ring width" }, { "tag": "tree rings" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T06:50:32Z", "dateModified": "2026-04-05T11:01:35Z" } }, { "key": "N6M43YVI", "version": 12183, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/N6M43YVI", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/N6M43YVI", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Vignola et al.", "parsedDate": "2026-03-04", "numChildren": 0 }, "data": { "key": "N6M43YVI", "version": 12183, "itemType": "journalArticle", "title": "Reconstructing post-crisis recovery in the hinterlands of Constantinople: A high-resolution first-millennium CE pollen record from Lake Yeniçağa (NW Türkiye)", "creators": [ { "creatorType": "author", "firstName": "Cristiano", "lastName": "Vignola" }, { "creatorType": "author", "firstName": "Mustafa", "lastName": "Doğan" }, { "creatorType": "author", "firstName": "Warren", "lastName": "Eastwood" }, { "creatorType": "author", "firstName": "John", "lastName": "Haldon" }, { "creatorType": "author", "firstName": "Alessia", "lastName": "Masi" }, { "creatorType": "author", "firstName": "Neil", "lastName": "Roberts" }, { "creatorType": "author", "firstName": "Çetin", "lastName": "Şenkul" }, { "creatorType": "author", "firstName": "Adam", "lastName": "Izdebski" } ], "abstractNote": "Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid-1st millennium CE. As a result, the rural economy of Anatolia transitioned from the intensive mixed-farming regime of the Graeco-Roman era to a more varied medieval agricultural system. We reconstruct here for the first time this transition in a region of Anatolia located close to Constantinople through pollen analysis of a sediment core from Lake Yeniçağa, dated to between 2300 and 1200 cal a BP. After discussing data for the Hellenistic–Roman era, we document repeated attempts at the recovery of mixed farming during the 6th to 8th c. CE. These attempts were only successful toward the end of our study period, with the stabilization of the military situation in the region, as is also visible in the written sources that we analyze in parallel in this paper. Crucially, this model of land exploitation was also constrained by the climatic oscillations that reflected its transitional location between the Aegean, Central Anatolian, and Black Sea climate regions. Thus, our study provides a perfect illustration of the interplay between environment and society in relation to the primary production sector (agriculture), in the dynamic context of a strong elite presence in the nearby capital city.\n\n【摘要翻译】面对新型瘟疫大流行、军事入侵和政治经济转型，东罗马 (拜占庭) 帝国的社会在公元 1 千纪中期不得不适应各种压力和开发自然环境的新方式。结果，安纳托利亚的农村经济从希腊罗马时代的集约化混合农业制度转变为更加多样化的中世纪农业体系。我们在这里首次通过对耶尼恰加湖沉积物岩芯的花粉分析，在安纳托利亚靠近君士坦丁堡的一个地区重建了这种转变，这个沉积物岩芯可以追溯到公元 2300 年至 1200 年之间。在讨论了希腊化 - 罗马时代的数据后，我们记录了公元 6 至 8 世纪复兴混合农业的多次尝试。这些尝试直到我们研究期结束时才取得成功，随着该地区军事局势的稳定，这一点在我们在本文中同时分析的书面资料中也有所体现。至关重要的是，这种土地开发模式也受到气候振荡的制约，这反映了其在爱琴海、安纳托利亚中部和黑海气候区域之间的过渡位置。因此，我们的研究为环境与社会之间的相互作用提供了一个完美的例证，这种相互作用与初级生产部门 (农业) 有关，这是在附近首都城市存在强大精英的动态背景下进行的。", "publicationTitle": "Journal of Quaternary Science", "publisher": "", "place": "", "date": "04 March 2026", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1002/jqs.70059", "citationKey": "Vignola2026", "url": "https://onlinelibrary.wiley.com/doi/abs/10.1002/jqs.70059", "accessDate": "2026-03-09T06:29:47Z", "PMID": "", "PMCID": "", "ISSN": "1099-1417", "archive": "", "archiveLocation": "", "shortTitle": "在君士坦丁堡腹地重建危机后恢复：来自叶尼恰加湖 (土耳其北部) 的公元第一个千年高分辨率花粉记录", "language": "en", "libraryCatalog": "2.2 (Q2)", "callNumber": "3", "rights": "© 2026 The Author(s).

The chronology of the studied lake-peat sequence, constrained by four radiocarbon (14C) ages, indicates that peat development in the region commenced around 6100 cal yr BP. Pollen combined with δ13C results reveal a significantly warmer and wetter climate between ∼6100 and 5300 cal yr BP, corresponding to the late phase of the Holocene Climate Optimum (HCO) in the upper Bhagirathi basin. Around ∼5300 cal yr BP, an abrupt climate shift occurred, which led to a prolonged dry spell between ∼4800 and 3400 cal yr BP. This dry spell was characterized by a decline in arboreal tree taxa, particularly Quercus, Alnus, and Betula, the complete disappearance of Juglans, and a notable increase in drought-tolerant herbs, such as Chenopodiaceae-Amaranthaceae and Ephedra. This prolonged cold-dry phase is correlated with a weakening of the Indian summer monsoon (ISM) intensity, as previously recorded in the core summer monsoon zone, in response to regional warming of the Indo-Pacific Warm Pool. Subsequent increase in arboreal tree taxa and moisture-loving pollen taxa, along with a reduced representation of drought-tolerant herbs, suggests a warm and wet climate between ∼3400 and 1600 cal yr BP (Roman Warm Period ∼2200 to 1600 cal yr BP), ∼1000 to 500 (Medieval Climate Anomaly), and from ∼130 cal yr BP to the Present (Current Warm Period). In contrast, the intermittent periods between ∼1600 and 1000 (Dark Ages Cold Period) and ∼ 500 to 130 cal yr BP (Little Ice Age, LIA) were dominated by cold and drought-tolerant desert steppe vegetation. The highest concentration of pollen and fern, especially from sub-alpine tree taxa, between ∼6100 and 5300 cal yr BP, suggests an upward shift of the tree line beyond its modern-day position, reflecting optimal climatic conditions. Conversely, during the LIA, the tree line descended to its lowest elevation in the past ∼6100 years. The strengthened ISM episodes during the middle to late Holocene likely provided the moisture necessary for the glacier advances in the upper Bhagirathi catchment.", "publicationTitle": "Palaeogeography, Palaeoclimatology, Palaeoecology", "publisher": "", "place": "", "date": "2026-04-15", "volume": "688", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "113614", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Palaeogeography, Palaeoclimatology, Palaeoecology", "DOI": "10.1016/j.palaeo.2026.113614", "citationKey": "Rawat2026", "url": "https://www.sciencedirect.com/science/article/pii/S0031018226000775", "accessDate": "2026-03-09T07:43:21Z", "PMID": "", "PMCID": "", "ISSN": "0031-0182", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "2.7 (Q1)", "callNumber": "2", "rights": "", "extra": "🏷️ /unread、Little Ice Age、Holocene、pollen、Himalaya、Medieval Climate Anomaly、Indian summer monsoon、Roman Warm Period、peat", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Himalaya", "type": 1 }, { "tag": "Holocene", "type": 1 }, { "tag": "Indian summer monsoon", "type": 1 }, { "tag": "Little Ice Age" }, { "tag": "Medieval Climate Anomaly" }, { "tag": "Roman Warm Period" }, { "tag": "peat" }, { "tag": "pollen" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-04-05T10:57:34Z" } }, { "key": "3IJIPRFC", "version": 12180, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/3IJIPRFC", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/3IJIPRFC", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Ning et al.", "parsedDate": "2026-02-09", "numChildren": 0 }, "data": { "key": "3IJIPRFC", "version": 12180, "itemType": "journalArticle", "title": "Progress and prospects of paleoclimate data assimilation", "creators": [ { "creatorType": "author", "firstName": "Liang", "lastName": "Ning" }, { "creatorType": "author", "firstName": "Jian", "lastName": "Liu" }, { "creatorType": "author", "firstName": "Zhengyu", "lastName": "Liu" }, { "creatorType": "author", "firstName": "Fangmiao", "lastName": "Xing" }, { "creatorType": "author", "firstName": "Fen", "lastName": "Wu" }, { "creatorType": "author", "firstName": "Mi", "lastName": "Yan" }, { "creatorType": "author", "firstName": "Zilu", "lastName": "Meng" }, { "creatorType": "author", "firstName": "Kefan", "lastName": "Chen" }, { "creatorType": "author", "firstName": "Yanmin", "lastName": "Qin" }, { "creatorType": "author", "firstName": "Weiyi", "lastName": "Sun" }, { "creatorType": "author", "firstName": "Qin", "lastName": "Wen" } ], "abstractNote": "Reconstructing paleoclimate characteristics and understanding their evolution rules is a key question in Earth system science and global change research.

Pollen analysis, supported by modern analogues from 25 surface samples, enabled reconstruction of Mean Annual Temperature (MAT) and Mean Annual Precipitation (MAP) across five pollen zones (SW-I to SW-V) using the Coexistence Approach (CA). The earliest phase (SW-I; 2090–310 BCE/4040–2260 cal. yrs. BP) indicates warm, humid conditions (MAT ≈ 30 °C; MAP ≈ 3000 mm) with dense forest cover, suggesting regional climatic resilience during the globally arid 4.2 ka event. The presence of Rhododendron and Castanopsis points to episodic flooding under unstable conditions. Between 310 BCE and 490 CE (SW-II; 2260–1460 cal. yrs. BP), vegetation became more open, warm and relatively less humid with fluctuating flood activity. A subsequent increased moist interval (850–1450 CE; SW-IV; 1100–500 cal. yrs. BP) corresponds to the Medieval Climatic Anomaly (MCA), marked by renewed deciduous forests and elevated MAP (∼2750 mm). Post-1450 CE (SW-V; 500 cal. yrs. BP onwards), declining MAT (13–22 °C) and MAP (500–1092 mm) indicate relatively less humid climate, in consonance to Little Ice Age cooling and enhanced human impact, evident by anthropic pollen and savanna-like vegetation. Granulometric shifts reveal transitions from low- to high-energy fluvial regimes through time. Overall, the record highlights monsoonal variability in the region during mid-late Holocene and underscores the importance of Majuli's depositional archives for assessing the resilience and sensitivity of tropical systems to past and future abrupt climate change.\n\n【摘要翻译】本研究整合了来自阿萨姆州马朱里岛濒危湿地 150 厘米深沉积物剖面的生物 (花粉) 和非生物 (粒度) 代理物，该剖面位于印度 - 缅甸生物多样性热点内，并受到印度夏季季风 (ISM) 的影响。花粉分析得到来自 25 个地表样本的现代类似物的支持，使用共存方法 (CA) 重建了五个花粉带 (SW-I 至 SW-V) 的平均年温度 (MAT) 和平均年降水量 (MAP)。最早阶段 (SW-I;公元前 2090-310 年/公元前 4040-2260 年) 表明温暖潮湿的条件 (MAT ≈ 30°C;MAP ≈ 3000 毫米)，并伴有茂密的森林覆盖，表明在全球干旱 4.2 ka 事件期间，该地区具有气候韧性。杜鹃花和卡斯塔诺普斯的存在表明，在不稳定条件下存在间歇性洪水。在公元前 310 年至公元 490 年 (SW-II;2260-1460 卡年 BP)，随着洪水活动的波动，植被变得更加开阔、温暖，且相对不那么潮湿。随后湿度增加的时间段 (850-1450 公元;SW-IV;1100-500 卡年 BP) 对应于中世纪气候异常 (MCA)，其特征是落叶林的更新和 MAP(约 2750 毫米) 的升高。公元 1450 年后 (SW-V;500 卡年 BP 以后),MAT(13-22°C) 和 MAP(500-1092 毫米) 的下降表明气候相对不那么潮湿，这与小冰期的降温和人类影响的增强相一致，这一点在人类花粉和热带稀树草原样植被中得到了明显体现。粒度变化揭示了随着时间的推移，从低能量河流制度向高能量河流制度的转变。总的来说，该记录突出了全新世中后期该地区的季风变化，并强调了马朱里沉积档案在评估热带系统对过去和未来突发气候变化的韧性和敏感性方面的重要性。", "publicationTitle": "Review of Palaeobotany and Palynology", "publisher": "", "place": "", "date": "2026-05-01", "volume": "348", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "105536", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Review of Palaeobotany and Palynology", "DOI": "10.1016/j.revpalbo.2026.105536", "citationKey": "Pandey2026", "url": "https://www.sciencedirect.com/science/article/pii/S0034666726000382", "accessDate": "2026-03-09T07:44:29Z", "PMID": "", "PMCID": "", "ISSN": "0034-6667", "archive": "", "archiveLocation": "2 被引", "shortTitle": "过去四千年的水文气候变化和植被响应：来自印度东北部马朱里岛的多代理记录", "language": "en", "libraryCatalog": "1.7 (Q2)", "callNumber": "3", "rights": "", "extra": "🏷️ /unread、precipitation、Little Ice Age、pollen、Medieval Climatic Anomaly、Assam、eastern India、Majuli Island", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Assam" }, { "tag": "Little Ice Age" }, { "tag": "Majuli Island", "type": 1 }, { "tag": "Medieval Climatic Anomaly" }, { "tag": "eastern India" }, { "tag": "pollen" }, { "tag": "precipitation" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-04-05T10:53:09Z" } }, { "key": "NLSEJCI8", "version": 12176, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/NLSEJCI8", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/NLSEJCI8", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Wang et al.", "parsedDate": "2026-01-20", "numChildren": 0 }, "data": { "key": "NLSEJCI8", "version": 12176, "itemType": "journalArticle", "title": "Integrated reconstruction of January and July temperature series in the Sanjiangyuan region during the Holocene", "creators": [ { "creatorType": "author", "firstName": "Yan", "lastName": "Wang" }, { "creatorType": "author", "firstName": "Guangchao", "lastName": "Cao" }, { "creatorType": "author", "firstName": "Guangliang", "lastName": "Hou" }, { "creatorType": "author", "firstName": "Jian", "lastName": "Ni" }, { "creatorType": "author", "firstName": "Tao", "lastName": "Huang" }, { "creatorType": "author", "firstName": "Li", "lastName": "Yan" }, { "creatorType": "author", "firstName": "Jinrong", "lastName": "Hu" } ], "abstractNote": "The Sanjiangyuan region, located in the hinterland of the Qinghai-Tibet Plateau(QTP), is highly sensitive to global climate change. Reconstructing its Holocene January and July temperatures is crucial for studying climate change and guiding ecological conservation in alpine regions. Current research on paleoclimate changes in Sanjiangyuan region primarily focuses on small subregions, limiting holistic understanding of regional climate.This study utilizes fossil pollen data, for the first time, integrates the Dynamic Multi-proxy Fusion and Scaling(DMFS) model to reconstruct the Holocene January and July temperature change sequences, thereby exploring temperature variations in the Sanjiangyuan region during 12.5 ka BP. The results indicated:12.5-6.0 ka BP: Both January and July temperatures showed a gradual increase,marking climatic improvement. 6.0-4.0 ka BP, both January and July temperatures remained at high levels, despite their fluctuations. During this period, temperatures reached their peak, reflecting a warm, humid, and most hospitable climate.4.0-2.5 ka BP: Both January and July temperatures showed declining trends to varying degrees, the climate became cold and dry. Post 2.5 ka BP: Both January and July temperatures rebounded. Comparisons with other high-resolution environmental records from the QTP confirmed consistent trends and synchronic dry-wet events. This study contributed essential fossil pollen data and paleotemperature records to the Sanjiangyuan region. This will fill a critical gap in paleoclimate research for the Sanjiangyuan region and provide valuable insights for long-term paleoclimate studies.\n\n【摘要翻译】三江源地区位于青藏高原腹地 (QTP)，对全球气候变化高度敏感。重建其全新世 1 月和 7 月温度对于研究气候变化和指导高寒地区生态保护至关重要。目前对三江源地区古气候变化的研究主要集中在较小的子区域，限制了对区域气候的整体理解。本研究利用化石花粉数据，首次整合动态多代理融合与缩放 (DMFS) 模型，重建全新世 1 月和 7 月温度变化序列，从而探索三江源地区 12.5 ka BP 期间的温度变化。结果表明:12.5-6。0 ka BP:1 月和 7 月的气温均呈现逐渐上升趋势，标志着气候的改善。6.0-4.0 ka BP，尽管气温有所波动，但 1 月和 7 月的气温均保持在高水平。在此期间，气温达到峰值，反映了温暖、潮湿且最宜人的气候。4.0-2.5 ka BP:1 月和 7 月的气温均呈现不同程度的下降趋势，气候变得寒冷和干燥。2.5 ka BP 之后:1 月和 7 月的气温都出现反弹。与 QTP 其他高分辨率环境记录的比较证实了一致的趋势和同步的干湿事件。本研究为三江源地区提供了重要的化石花粉数据和古气温记录。这将填补三江源地区古气候研究中的关键空白，并为长期古气候研究提供宝贵的见解。", "publicationTitle": "PLOS ONE", "publisher": "Public Library of Science", "place": "", "date": "Jan 20, 2026", "volume": "21", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "e0337521", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "PLOS ONE", "DOI": "10.1371/journal.pone.0337521", "citationKey": "Wang2026e", "url": "https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0337521", "accessDate": "2026-03-09T07:44:49Z", "PMID": "", "PMCID": "", "ISSN": "1932-6203", "archive": "", "archiveLocation": "", "shortTitle": "全新世时期三江源地区 1 月和 7 月气温序列的综合重建", "language": "en", "libraryCatalog": "2.6 (Q2)", "callNumber": "3", "rights": "", "extra": "🏷️ /unread、Tibetan Plateau、Holocene、pollen、summer temperature、winter temperature", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Holocene" }, { "tag": "Tibetan Plateau" }, { "tag": "pollen" }, { "tag": "summer temperature" }, { "tag": "winter temperature" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-04-05T10:51:40Z" } }, { "key": "GFPLWILC", "version": 12175, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/GFPLWILC", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/GFPLWILC", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Qu et al.", "parsedDate": "2026-04-15", "numChildren": 0 }, "data": { "key": "GFPLWILC", "version": 12175, "itemType": "journalArticle", "title": "Holocene precipitation/humidity change trend in subtropical southern China: Contrary results, analyses and prospective", "creators": [ { "creatorType": "author", "firstName": "Xiaoxu", "lastName": "Qu" }, { "creatorType": "author", "firstName": "Yunxia", "lastName": "Li" }, { "creatorType": "author", "firstName": "Zhongwei", "lastName": "Shen" }, { "creatorType": "author", "firstName": "Lin", "lastName": "Zhao" }, { "creatorType": "author", "firstName": "Siyu", "lastName": "Wu" }, { "creatorType": "author", "firstName": "Zhiguo", "lastName": "Rao" } ], "abstractNote": "The long-term overall Holocene change trend of precipitation/humidity in subtropical southern China (SSC), which being critical for the complete understand of the Holocene evolution history of East Asian summer monsoon (EASM), remains highly controversial. Pollen-based mean annual precipitation (MAP) reconstructions from SSC indicate a gradual decrease since ∼6 ka BP, whereas non-pollen-based precipitation/humidity records mostly suggest a long-term increasing trend. During the period 1901–2020 CE, the Empirical Orthogonal Function (EOF) analysis of annual, summer precipitation amount and ratio of summer/annual precipitation all showed opposite decreasing and increasing trends in temperate northern China (TNC) and SSC respectively, indicating a weakening trend of EASM intensity and an increasingly prolonged stagnation of the monsoon rain belt over SSC, which being supported by the modern EASM index. During the same period, the modern stalagmite δ18O records in both TNC and SSC generally showed an overall more positive trend, highlighting its potential as an indicator of the EASM intensity with more positive stalagmite δ18O values corresponding to reduced EASM intensity. Taking the above-mentioned modern situations as an analogue, the Holocene stalagmite δ18O records in both TNC and SSC that generally showed a long-term overall more positive trend too since ∼6 ka BP, should indicate the coeval long-term overall decreasing trend of the EASM intensity. This is further supported by the Holocene records from TNC, which generally showing a long-term overall drying trend since ∼6 ka BP. By further in-depth analysis of the paleoclimatic records in SSC, the pollen-based reconstructions in SSC may have been substantially influenced by human activity, which makes the inferred long-term drying trend in SSC since ∼6 ka BP quite possibly unreliable. This anthropogenic impact on pollen-based reconstructions has been specifically observed in a study from the Zhaogongting (ZGT) peatland in SSC. Therefore, we incline to accept the long-term overall increasing trend in precipitation/humidity across the SSC since ∼6 ka BP. Consequently, we appeal for more studies on the long-term overall Holocene precipitation/humidity change trend in SSC, and we emphasize that the impacts of human activities on the adopted proxies should be carefully evaluated and corrected in future relevant works.\n\n【摘要翻译】中国南部亚热带地区 (SSC) 全新世降水/湿度的长期整体变化趋势对于全面理解东亚夏季风 (EASM) 的全新世演化历史至关重要，但仍然存在高度争议。来自 SSC 的基于花粉的年平均降水量 (MAP) 重建结果表明，自约 6 ka BP 以来，降水/湿度呈现逐渐下降的趋势，而非基于花粉的降水/湿度记录主要表明长期呈现上升趋势。1901-2020 年期间，经验正交函数 (EOF) 分析显示，中国北方温带 (TNC) 和南方温带 (SSC) 的年降水量、夏季降水量和夏季/年降水比均呈现出相反的减少和增加趋势，表明 EASM 强度呈减弱趋势，季风雨带在 SSC 上空的停滞时间越来越长，这得到了现代 EASM 指数的支持。同期，TNC 和 SSC 的现代石笋δ18O 记录总体呈现更正的趋势，突显了其作为 EASM 强度指标的潜力，石笋δ18O 值更正，对应于 EASM 强度的减弱。以上述现代情况为类比，TNC 和 SSC 的全新世石笋δ18O 记录自约 6 ka BP 以来也普遍表现出长期整体更为正向的趋势，这应该表明同期 EASM 强度的长期整体下降趋势。TNC 的全新世记录进一步支持了这一观点，这些记录自约 6 ka BP 以来普遍表现出长期整体干燥趋势。通过对 SSC 古气候记录的进一步深入分析，SSC 的花粉基重建可能受到人类活动的显著影响，这使得 SSC 自约 6 ka BP 以来推测的长期干燥趋势很可能不可靠。在 SSC 兆功亭 (ZGT) 泥炭地的一项研究中，已经特别观察到这种人为因素对花粉基重建的影响。因此，我们倾向于接受 SSC 自约 6 ka BP 以来降水/湿度的长期整体增长趋势。因此，我们呼吁对 SSC 长期整体全新世降水/湿度变化趋势进行更多研究，并强调在未来的相关工作中应仔细评估和纠正人类活动对采用替代物的影响。", "publicationTitle": "Quaternary Science Reviews", "publisher": "", "place": "", "date": "2026-04-15", "volume": "378", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "109883", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Quaternary Science Reviews", "DOI": "10.1016/j.quascirev.2026.109883", "citationKey": "Qu2026", "url": "https://www.sciencedirect.com/science/article/pii/S0277379126000922", "accessDate": "2026-03-09T07:44:34Z", "PMID": "", "PMCID": "", "ISSN": "0277-3791", "archive": "", "archiveLocation": "", "shortTitle": "中国南方亚热带地区全新世降水/湿度变化趋势：相反的结果、分析和前景", "language": "en", "libraryCatalog": "3.3 (Q2)", "callNumber": "2", "rights": "", "extra": "🏷️ /unread、Holocene、pollen、southern China、Eas Asian summer monsoon、peat", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Eas Asian summer monsoon" }, { "tag": "Holocene", "type": 1 }, { "tag": "peat" }, { "tag": "pollen" }, { "tag": "southern China" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-04-05T10:51:16Z" } }, { "key": "WRR46PCL", "version": 12174, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/WRR46PCL", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/WRR46PCL", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Larocca et al.", "parsedDate": "2026", "numChildren": 0 }, "data": { "key": "WRR46PCL", "version": 12174, "itemType": "journalArticle", "title": "Glacier Equilibrium-Line Altitude Change Across Alaska and Adjacent Canada Indicates a Cold, Dry Little Ice Age and Weaker Aleutian Low", "creators": [ { "creatorType": "author", "firstName": "L.

Here, we assess the impacts of major eruptions over the Last Millennium on surface air temperature (SAT), Palmer drought severity index (PDSI), and 500-hPa geopotential height using tree-ring reconstructions, nine data assimilation (DA) products, and two climate model ensembles. We confirm robust global SAT cooling but find large differences in magnitude and persistence: Reconstructions based on tree-ring density show shorter, physically consistent cooling, whereas products dominated by tree-ring widths show longer persistence, likely reflecting biological memory. PDSI responses reveal coherent wetting over the western United States, the Mediterranean Basin, and southern South America, and coherent drying over northern and European Russia, central Asia, and southern Siberia, with divergence elsewhere. El Niño–Southern Oscillation responses differ across products, suggesting that any volcanically forced signal is weak relative to internal variability and highly sensitive to the background climate state. Geopotential height anomalies reveal widespread posteruption tropospheric contraction and robust extratropical circulation shifts, including negative height anomalies over mid- to high latitudes and wave-like patterns in the Southern Hemisphere. These anomalies are dynamically consistent with the spatial patterns of wetting and drying in PDSI, suggesting that volcanic forcing reorganizes large-scale atmospheric circulation in ways that influence hydroclimate. Together, these findings provide a comprehensive framework for interpreting volcanic impacts, strengthen confidence in regions with robust signals, and identify priority areas—particularly in the tropics and the Southern Hemisphere—where additional proxy coverage could reduce current uncertainties. Significance Statement This study presents the first comprehensive intercomparison of volcanic impacts on temperature, hydroclimate, and atmospheric circulation from tree-ring reconstructions, data assimilation products, and climate model ensembles. Reconstructions based on tree-ring density are the physically most consistent benchmark, showing shorter and more realistic duration of cooling, whereas products dominated by tree-ring widths overestimate persistence resulting from biological memory. Hydroclimate responses reflect coherent wetting in the western United States, the Mediterranean, and southern South America, and coherent drying in northern and European Russia, central Asia, and southern Siberia, with minimal agreement elsewhere. Responses of the El Niño–Southern Oscillation phenomenon remain inconsistent between products. We also connect hydroclimate signals with posteruption atmospheric height anomalies and associated extratropical circulation changes to provide a clearer framework for interpreting how volcanoes impact interactions between the ocean and atmosphere. This linkage also helps pinpoint priority regions—especially across the tropics and the Southern Hemisphere—where expanded, high-resolution proxy records could most effectively narrow current uncertainties.\n\n【摘要翻译】已知大型火山喷发在几年内对全球气候有显著影响，但尚未对越来越多的古气候数据集进行全面比较。在本文中，我们利用树轮重建、9 个数据设同化 (DA) 产品和两个气候模型集合，评估了过去千年中主要火山喷发对地表气温 (SAT)、帕尔默干旱严重程度指数 (PDSI) 和 500 hPa 位势高度的影响。我们证实了全球 SAT 冷却强劲，但在规模和持续性方面存在较大差异：基于树轮密度的重建显示较短的、物理一致的冷却，而以树轮宽度为主的产品显示较长的持续性，可能反映了生物记忆。PDSI 响应显示，美国西部、地中海盆地和南美洲南部地区持续湿润，而俄罗斯北部和欧洲地区、中亚和西伯利亚南部地区持续干燥，其他地区则存在差异。厄尔尼诺 - 南方涛动现象反应因产物而异，表明任何火山强迫信号相对于内部变异性都较弱，并且对背景气候状态高度敏感。位势高度异常揭示了广泛的对流层收缩和强烈的热带外环流变化，包括中高纬度地区的负位势高度异常和南半球的波状模式。这些异常与 PDSI 中湿润和干燥的空间模式动态一致，表明火山强迫以影响水文气候的方式重组大规模大气环流。综上所述，这些发现为解释火山影响提供了一个全面的框架，增强了对信号强烈地区的信心，并确定了优先考虑的区域——特别是在热带和南半球——在这些地区，额外的代理覆盖可以减少当前的不确定性。显著性状态本研究首次全面比较了火山对温度、水文气候和大气环流的影响，这些影响来自树木年轮重建、数据同化产品和气候模型集合。基于树木年轮密度的重建是物理上最一致的基准，显示了更短和更真实的冷却持续时间，而以树木年轮宽度为主导的产品高估了由生物记忆引起的持续性。水文气候响应反映了美国西部、地中海和南美洲的一致性降水，以及俄罗斯北部和欧洲地区、中亚和西伯利亚南部的一致性干旱，其他地区的一致性最小。厄尔尼诺 - 南方涛动现象的反应在不同产品之间仍然不一致。我们还将水文气候信号与后续大气高度异常以及相关的热带外环流变化联系起来，以提供一个更清晰的框架来解释火山如何影响海洋和大气之间的相互作用。这种联系还有助于确定优先区域——特别是在热带和南半球——在这些区域，扩展的、高分辨率的代理记录可以最有效地缩小当前的不确定性。", "publicationTitle": "Journal of Climate", "publisher": "American Meteorological Society", "place": "", "date": "2026/02/23", "volume": "39", "issue": "5", "section": "Journal of Climate", "partNumber": "", "partTitle": "", "pages": "1295-1313", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1175/JCLI-D-25-0179.1", "citationKey": "He2026", "url": "https://journals.ametsoc.org/view/journals/clim/39/5/JCLI-D-25-0179.1.xml", "accessDate": "2026-03-09T07:45:01Z", "PMID": "", "PMCID": "", "ISSN": "0894-8755, 1520-0442", "archive": "", "archiveLocation": "", "shortTitle": "在过去一千年古气候重建和模型模拟中，全球气候对大型热带火山喷发的响应比较", "language": "en", "libraryCatalog": "journals-ametsoc-org.libproxy.helsinki.fi", "callNumber": "2", "rights": "", "extra": "", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "ENSO", "type": 1 }, { "tag": "data assimilation" }, { "tag": "drought" }, { "tag": "ring density" }, { "tag": "ring width" }, { "tag": "temperature" }, { "tag": "tree rings" }, { "tag": "volcanic forcing" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-04-05T10:48:24Z" } }, { "key": "G2RC4MP2", "version": 12172, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/G2RC4MP2", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/G2RC4MP2", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Abidi et al.", "parsedDate": "2026-04-01", "numChildren": 0 }, "data": { "key": "G2RC4MP2", "version": 12172, "itemType": "journalArticle", "title": "Long-term streamflow reconstruction of The Medjerda River, Tunisia, from tree rings", "creators": [ { "creatorType": "author", "firstName": "Sahar", "lastName": "Abidi" }, { "creatorType": "author", "firstName": "David M.", "lastName": "Meko" }, { "creatorType": "author", "firstName": "Ramzi", "lastName": "Touchan" }, { "creatorType": "author", "firstName": "Mehvish", "lastName": "Majeed" }, { "creatorType": "author", "firstName": "Ali", "lastName": "Khorchani" } ], "abstractNote": "1 Study region\nShort instrumental discharge data limit our understanding of long-term hydrological variability in North African river basins. The Medjerda River, Tunisia's most important watercourse, has discharge data dating back only to the 1950s, making effective water resource management challenging in an area already stressed by climate unpredictability and severe droughts.\n2 Study focus\nWe present a tree-ring-based reconstruction of Medjerda River discharge, 1876–2009, from a set of 7 Pinus halepensis tree-ring chronologies. An observed natural flow discharge series, to calibrate the reconstruction model, is generated from precipitation and temperature data with the aid of a web-based dendrohydrology platform.\n3 New hydrologic insights for the region\nThe reconstruction, calibrated over 1934–2009, explains 54 % of discharge variability and captures key hydroclimatic trends over yearly and decadal timescales. Single-year record highs and lows in reconstructed discharge occurred in the 2000s, but the largest departures in the smoothed (5-year) data occurred in the 1880s and 1940s. The reconstruction highlights the importance of considering longer time horizons for planning water resources in the Medjerda Basin, as well as the value of tree-ring data in conjunction with a water balance model for hydrologic reconstruction in basins with short or highly distorted gauged flow records. For the Medjerda Basin, results highlight the need for expanded tree-ring collections to achieve a longer reconstruction horizon. Improvement in the reconstruction signal for wet years is another pressing need.\n\n【摘要翻译】1 研究区域\n短暂的仪器泄洪数据限制了我们对北非河流流域长期水文变化的理解。突尼斯最重要的水道梅杰尔达河的泄洪数据只能追溯到 20 世纪 50 年代，这使得在一个已经受到气候不可预测性和严重干旱影响的地区进行有效的水资源管理变得具有挑战性。\n2 研究重点\n我们基于一组 7 个地中海松树环年表，对 1876-2009 年梅杰尔达河流域的流量进行了树环重建。利用基于网络的树木水文学平台，从降水和温度数据中生成了一个观测到的自然流量序列，用于校准重建模型。\n3 该地区的新水文见解\n重建结果经过 1934-2009 年的校准，解释了 54% 的流量变异性，并捕捉到了年度和十年时间尺度上的关键水文气候趋势。重建流量的单年记录高峰和低谷出现在 21 世纪初，但平滑 (5 年) 数据的最大偏差出现在 19 世纪 80 年代和 40 年代。重建结果强调了考虑更长时间范围对梅杰尔达流域水资源规划的重要性，以及树轮数据与水平衡模型相结合的价值，这些模型适用于具有短期或高度失真测量流量记录的流域的水文重建。对于梅杰尔达流域，结果强调了扩大树轮集群以实现更长重建时间范围的必要性。改善湿润年份的重建信号是另一个迫切的需求。", "publicationTitle": "Journal of Hydrology: Regional Studies", "publisher": "", "place": "", "date": "2026-04-01", "volume": "64", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "103262", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Journal of Hydrology: Regional Studies", "DOI": "10.1016/j.ejrh.2026.103262", "citationKey": "Abidi2026", "url": "https://www.sciencedirect.com/science/article/pii/S2214581826001606", "accessDate": "2026-03-09T07:44:54Z", "PMID": "", "PMCID": "", "ISSN": "2214-5818", "archive": "", "archiveLocation": "", "shortTitle": "突尼斯迈杰尔达河的长期河流重建，通过树木年轮", "language": "en", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "Medjerda River" }, { "tag": "Tunisia" }, { "tag": "Water resource management", "type": 1 }, { "tag": "ring width" }, { "tag": "streamflow" }, { "tag": "tree rings" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-04-05T10:46:26Z" } }, { "key": "P33UI3AA", "version": 12170, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/P33UI3AA", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/P33UI3AA", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Mitwally et al.", "parsedDate": "2026-04-01", "numChildren": 0 }, "data": { "key": "P33UI3AA", "version": 12170, "itemType": "journalArticle", "title": "Environmental changes in western Siberia over the past 1800 years reconstructed by geochemical and biological records of a well-dated core from Zolotoe Lake in Altai Krai, Russia", "creators": [ { "creatorType": "author", "firstName": "Eslam M.

The comparisons of paired 14C ages of A- and ABA-treated sedimentary total organic carbon (TOC) from 20 horizons indicate that old carbon influence (OCI) existed on some ABA-treated samples due to uptake of dissolved CO2 in the lake water. Combining sedimentary feature, mineralogy, geochemical proxies and pollen assemblages, we reconstructed detailed environmental changes since 200 CE. The acid-leachable (0.5N HCl, AL) elements and Aqua Regia open dissolution (AR) elements measured by ICP-OES were discussed for deciphering lake chemistry and terrestrial input. In the Zolotoe Lake core, AL Ca/K instead of Sr/Ca and Mg/Ca is an indicator of lake salinity, with higher ratio reflecting higher salinity; and vice versa. AL Al/Ti is positively correlated with surface runoff. AL Mn/Fe and Mn/Al (rather than AL U/Al) are proxies for redox conditions with higher ratio pointing more oxic conditions. During Roman Warm Period (RWP, 200-400 CE) warming and wet conditions were prevailing. Cold and wet climates occurred during Dark Ages Cold Period (DACP, 450-800 CE). Many lakes in the Volchikhinsky lake system might be connected at that time to form a large lake. During the Medieval Climate Anomaly (MCA, 900-1300 CE), warm and relatively wet conditions prevailed in the interval 900-1200 CE; but from 1200 to 1300 CE climate was warmer and drier. Colder and drier conditions coincided with the early Little Ice Age (LIA) (1400-1750 CE), but the late LIA (1750-1850 CE) climate was cold and wet. The large Volchikhinsky Lake became a lake system with separated small lakes around 1600 CE.

Here we introduce a new class of threshold-exceedance-amount metrics that consistently track changes in event frequency, duration, magnitude, area, and timing aspects like daily exposure and seasonal shift—as separate metrics, partially compound (e.g., average event severity), and as compound total events extremity (TEX). Building on daily temperature datasets over 1961 to 2024, we applied the new metrics to extreme heat events at local-to country-scale (example Austria) and across Europe, demonstrating their utility through this use. Comparing the recent period 2010–2024 to the reference period 1961–1990, we reveal amplification factors of around 10 [5 to 25] in the TEX of extreme heat over Austrian and most central and southern European regions. This degree of amplification is found to strongly exceed the natural variability, providing unequivocal evidence of anthropogenic climate change. Given their fundamental capacity to reliably track any threshold-defined hazard at any location, the new metrics can support a myriad of uses beyond this example application. These range from climate impact analyses for extremes such as heatwaves, floods and droughts to extreme events attribution, quantifying the anthropogenic share of a hazard extremity and of its damage to properties and harm to people.", "publicationTitle": "Weather and Climate Extremes", "publisher": "", "place": "", "date": "2026-03-01", "volume": "51", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "100855", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Weather and Climate Extremes", "DOI": "10.1016/j.wace.2026.100855", "citationKey": "Kirchengast2026", "url": "https://www.sciencedirect.com/science/article/pii/S221209472600006X", "accessDate": "2026-03-09T07:43:34Z", "PMID": "", "PMCID": "", "ISSN": "2212-0947", "archive": "", "archiveLocation": "", "shortTitle": "A new class of climate hazard metrics and its demonstration", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Europe" }, { "tag": "attribution" }, { "tag": "global warming" }, { "tag": "heat waves" } ], "collections": [], "relations": {}, "dateAdded": "2026-03-09T08:04:06Z", "dateModified": "2026-03-09T19:11:27Z" } }, { "key": "YAYUBU8W", "version": 12170, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/YAYUBU8W", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/YAYUBU8W", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 5985359, "username": "ntthung", "name": "Hung Nguyen", "links": { "alternate": { "href": "https://www.zotero.org/ntthung", "type": "text/html" } } }, "creatorSummary": "Qin et al.", "parsedDate": "2026", "numChildren": 0 }, "data": { "key": "YAYUBU8W", "version": 12170, "itemType": "journalArticle", "title": "Preferred Time Scales of Pacific Decadal Variability During the Last Millennium Related to Volcanic Activity", "creators": [ { "creatorType": "author", "firstName": "Yanmin", "lastName": "Qin" }, { "creatorType": "author", "firstName": "Zhengyu", "lastName": "Liu" }, { "creatorType": "author", "firstName": "Liang", "lastName": "Ning" }, { "creatorType": "author", "firstName": "Jian", "lastName": "Liu" }, { "creatorType": "author", "firstName": "Longhui", "lastName": "Li" }, { "creatorType": "author", "firstName": "Yuntao", "lastName": "Bao" }, { "creatorType": "author", "firstName": "Wenqing", "lastName": "Hu" }, { "creatorType": "author", "firstName": "Peng", "lastName": "Gu" }, { "creatorType": "author", "firstName": "Mi", "lastName": "Yan" }, { "creatorType": "author", "firstName": "Weiyi", "lastName": "Sun" }, { "creatorType": "author", "firstName": "Kefan", "lastName": "Chen" }, { "creatorType": "author", "firstName": "Qin", "lastName": "Wen" } ], "abstractNote": "Pacific Decadal Variability (PDV) plays a significant role in modulating the global climate change on decadal time scale.

But as Joseph Giacomelli shows in Uncertain Climes, this is actually nothing new: as far back as Gilded Age America, climate uncertainty has infused major debates on economic growth and national development.   In this ambitious examination of late-nineteenth-century understandings of climate, Giacomelli draws on the work of scientists, foresters, surveyors, and settlers to demonstrate how central the subject was to the emergence of American modernity. Amid constant concerns about volatile weather patterns and the use of natural resources, nineteenth-century Americans developed a multilayered discourse on climate and what it might mean for the nation’s future. Although climate science was still in its nascent stages during the Gilded Age, fears and hopes about climate change animated the overarching political struggles of the time, including expansion into the American West.

However, assessments of Holocene variability in storminess rarely consider whether major volcanic eruptions could be a possible driver of reconstructed periods of enhanced storminess. This research presents a new reconstruction of past storminess from a coastal peatbog situated in western Ireland spanning the last ∼ 7 ka. The record is based on the measurement of the sand content along the core, with XRF core scanning analysis also applied to test whether variations in quartz sand, shell sand and sea spray can be detected by variations in silica, calcium and bromine respectively. Ca measurements were similar to the long-term changes in sand content along the core, however, peaks in sand content were not detected, while Si reflected increases in sand content only within the last millennium when the inorganic content was highest. Br concentrations appear to have been influenced primarily by humification. We also compared sand-based storminess records from northwest Europe. Six multi-decadal to centennial periods with enhanced storminess are common to records from Ireland and Wales during the last 2.5 ka BP, centred at c. 2.25, 2, 1.4, 1.1, 0.5 and 0.2 ka BP, with less agreement between records before this time. The storm periods at 2.8, 2.2–2, 1.1 and 0.5 ka BP are more widespread events and agree with records from Sweden and Scotland. Each of the episodes of increased storminess coincide roughly with major volcanic eruptions during the late Holocene, as well as with periods of enhanced North Atlantic ice-rafting. We hypothesise, therefore, that both enhanced storminess and ice-rafting may have resulted from the climate and environmental impacts of these eruptions, aligning with the findings of recent observational and modelling studies on the climate response to eruptions. Challenges remain, however, in testing this hypothesis, given chronological uncertainties in peatland records and uncertain interpretations of the factors influencing sand deposition. Therefore, to provide an independent assessment of the influence of explosive eruptions on storminess for Ireland's northeast Atlantic position, we draw upon the rich tradition of annalistic record keeping on the island, including many reports of major storms and windy seasons, to develop a windiness index running from the sixth to seventeenth centuries CE.

The radiocarbon and optically stimulated luminescence dating methods applied to the North-20240227 core. Sandy layers below the lacustrine sediment sequence probably indicate dramatic lake level lowering between ∼300 CE and 1200 CE, corresponding dry phase in the region. A subsequent recovery of lake conditions, linked to the increased river inflow by the topographic shifts, marks a wetter phase after ∼1200 CE and coinciding with the expansion of the Mongolian empire. After ∼1400 CE, enhanced carbonate precipitation suggests another dry period, which potentially coincided with the decline of Mongolian empire. The high sediment rate and coarsening grain size in the North-20240227 core show intensified aeolian input due to continued lake shrinkage after ∼1850 CE.

This study presents a high-resolution, interdisciplinary reconstruction of ecosystem changes over the last ~ 600 years (ca. 1400–2022 CE) from the Mar Piccolo basin (Taranto, Southern Italy), a representative semi-enclosed coastal system under long-term cumulative stress. Through multiproxy analyses of a dated sediment core (S05B) and modern environmental archives (surface sediments and moss samples), we integrate palynological indicators (pollen plus dinocysts and other non-pollen palynomorphs) with historical and ecological records. This unique integration of proxy and documentary/archival evidence enables an exceptional comparison of natural and anthropogenic dynamics across centuries. Results reveal a progressive and marked decline in ecosystem integrity, reflected in the sharp reduction of native thermophilous forest taxa (e.g., deciduous Quercus), an increase in anthropogenic (e.g., Olea) and ruderal (e.g., Plantago lanceolata-type) taxa, along with a rise in eutrophication-related dinocysts (e.g., Lingulodinium machaerophorum) since the early fifteenth century. The Little Ice Age intensified environmental and socio-economic stress, accelerating transformations in both terrestrial and marine domains. In recent decades, warming trends, altered hydrology, and landscape fragility have further reduced system resilience, as evidenced by persistent records of parasite eggs (e.g., Ascaris) indicating long-term wastewater contamination and potential health risks. This case study demonstrates how coupled human–environment systems in semi-enclosed Mediterranean basins respond to prolonged and interacting pressures. The multiproxy approach offers a transferable framework for detecting ecological tipping points and supporting evidence-based restoration and adaptive management strategies.\n\n【摘要翻译】地中海地区的沿海过渡生态系统正日益受到气候变化、土地利用集约化和遗留污染等综合影响的威胁。本研究提出了一项高分辨率、跨学科的生态系统变化重建研究，该研究来自马尔皮科洛盆地 (意大利南部塔兰托)，这是一个具有代表性的半封闭沿海系统，长期处于累积压力之下。通过对已确定年代的沉积物核心 (S05B) 和现代环境档案 (表层沉积物和苔藓样本) 的多重代理分析，我们将孢粉学指标 (花粉加恐囊动物和其他非花粉孢形体) 与历史和生态记录相结合。这种代理和文献/档案证据的独特整合，使我们能够对几个世纪以来的自然和人为动力学进行非凡的比较。结果显示，生态系统完整性呈现出逐步且显著的下降趋势，这反映在原生热带森林类群 (如落叶栎) 的急剧减少、人源性类群 (如 Olea) 和原始性类群 (如长叶车前型) 的增加，以及自 15 世纪初以来富营养化相关恐龙囊虫 (如舌藻) 的增加。小冰期加剧了环境和社会经济压力，加速了陆地和海洋领域的转型。近几十年来，变暖趋势、水文学变化和景观脆弱性进一步降低了系统韧性，这一点从持续记录的寄生虫卵 (如蛔虫) 中得到了证明，这些记录表明长期存在废水污染和潜在的健康风险。本案例研究展示了半封闭的地中海流域中人类 - 环境耦合系统如何应对长期和相互作用的压力。多代理方法提供了一个可转移的框架，用于检测生态临界点，并支持基于证据的修复和适应性管理策略。", "publicationTitle": "Regional Environmental Change", "publisher": "", "place": "", "date": "2026-02-07", "volume": "26", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "39", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Reg Environ Change", "DOI": "10.1007/s10113-026-02527-9", "citationKey": "niccoliniSixCenturies15th21st2026", "url": "https://doi.org/10.1007/s10113-026-02527-9", "accessDate": "2026-02-24T14:48:37Z", "PMID": "", "PMCID": "", "ISSN": "1436-378X", "archive": "", "archiveLocation": "", "shortTitle": "意大利南部马尔皮科洛 6 个世纪 (15-21 世纪) 的环境变化和土地利用：孢粉学和历史证据", "language": "en", "libraryCatalog": "3.6 (Q2)", "callNumber": "2", "rights": "", "extra": "🏷️ /unread、biodiversity、eutrophication、pollen、societal impacts、human–environment interactions、paleoenvironmental reconstruction、southern Italy", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "biodiversity" }, { "tag": "eutrophication" }, { "tag": "human–environment interactions" }, { "tag": "paleoenvironmental reconstruction" }, { "tag": "pollen" }, { "tag": "societal impacts" }, { "tag": "southern Italy" } ], "collections": [], "relations": {}, "dateAdded": "2026-02-24T14:55:19Z", "dateModified": "2026-02-25T10:14:52Z" } }, { "key": "644WB4UF", "version": 12161, "library": { "type": "group", "id": 22111, "name": "Historical Climatology Network Bibliographical Project", "links": { "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/22111/items/644WB4UF", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/historical_climatology_network_bibliographical_project/items/644WB4UF", "type": "text/html" } }, "meta": { "createdByUser": { "id": 301066, "username": "saw2105", "name": "Sam White", "links": { "alternate": { "href": "https://www.zotero.org/saw2105", "type": "text/html" } } }, "lastModifiedByUser": { "id": 9068947, "username": "xing2meng", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/xing2meng", "type": "text/html" } } }, "creatorSummary": "Bassnett", "parsedDate": "2026-01", "numChildren": 0 }, "data": { "key": "644WB4UF", "version": 12161, "itemType": "journalArticle", "title": "One British Archive: The Weather Extremes in England's Little Ice Age Database", "creators": [ { "creatorType": "author", "firstName": "Madeline", "lastName": "Bassnett" } ], "abstractNote": "This article introduces the open access ArcGIS database Weather Extremes in England's Little Ice Age, 1500–1700. The database maps narrative weather records from a range of sources, including historical chronicles, personal diaries, and extreme weather pamphlets. A source of particular note is the manuscript commonplace book of Richard Shann (1561–1627), a Catholic copyholder from Methley, Yorkshire. Shann included his weather notations in two distinct sections, with the first transcribing events between 1617–27, and the second, between 1586–1622. Falling between the genres of chronicle and diary, these records provide a sustained perspective on local weather conditions. In their turn-of-the-century focus, they also help to clarify the specific impact of the Little Ice Age on England, as their local observations reflect a national trend wherein seventeenth-century weather becomes not only more cold but also more unstable.\n\n【摘要翻译】本文介绍了公开访问的 ArcGIS 数据库 Weather Extremes in England‘s Little Ice Age,1500-1700。该数据库绘制了来自多个来源的叙事性天气记录，包括历史编年史、个人日记和极端天气小册子。一个特别值得注意的来源是 Richard Shann(1561-1627) 的手稿备忘录，他是来自约克郡 Methley 的一位天主教抄写员。Shan 将他的天气记录分为两个不同的部分，第一部分记录了 1617-1627 年间的事件，第二部分记录了 1586-1622 年间的事件。这些记录介于编年史和日记之间，为当地天气状况提供了持续的视角。在世纪之交的关注点中，它们还有助于阐明小冰期对英格兰的具体影响，因为它们的当地观察反映了一个全国趋势，即 17 世纪的天气不仅变得更冷，而且更加不稳定。", "publicationTitle": "Journal of British Studies", "publisher": "", "place": "", "date": "2026/01", "volume": "65", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "e4", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1017/jbr.2025.10187", "citationKey": "bassnettOneBritishArchive2026", "url": "https://www.cambridge.org/core/journals/journal-of-british-studies/article/one-british-archive-the-weather-extremes-in-englands-little-ice-age-database/E31896081817ACEB5EA88689D86234CC", "accessDate": "2026-02-24T14:50:09Z", "PMID": "", "PMCID": "", "ISSN": "0021-9371, 1545-6986", "archive": "", "archiveLocation": "", "shortTitle": "英国档案馆：英格兰小冰河时代数据库中的极端天气", "language": "en", "libraryCatalog": "0.7 (Q1)", "callNumber": "1", "rights": "", "extra": "🏷️ /unread、Little Ice Age、historical climatology、England、database", "tags": [ { "tag": "/unread", "type": 1 }, { "tag": "England" }, { "tag": "Little Ice Age" }, { "tag": "database" }, { "tag": "historical climatology" } ], "collections": [], "relations": {}, "dateAdded": "2026-02-24T14:55:19Z", "dateModified": "2026-02-25T10:13:56Z" } } ]
