Slow and diverse: Upslope expansion of tree species since 1854 in the Bavarian Alps (Germany) detected by citizen science by Sabine Rösler, Michelangelo Olleck, Karl H. Mellert, Jörg Ewald

“…We motivated mountain hikers to survey high-altitude occurrences of selected tree and shrub species in the Bavarian Alps in a citizen science portal and compared the observations with historical data collected by the botanist Otto Sendtner at the end of the Little Ice Age. For nine of ten species with sufficient numbers of historical and citizen science observations, currently uppermost outpost occurrences were verified after data curation and subsampling. …”

Capturing the transition from marine to land-terminating glacier from the 126-year retreat history of Nordenskiöldbreen, Svalbard by Jan Kavan, Petra Luláková, Jakub Małecki, Mateusz Czesław Strzelecki

“…Svalbard has experienced a dramatic increase in air temperature and glacier retreat since the end of the Little Ice Age. In many cases, this retreat has resulted in glaciers transitioning from being marine-terminating to land-terminating. …”

Recurring cycles of ice and vegetation on Baffin Island, Nunavut by Martha K. Raynolds, Helga Bültmann, Shawnee A. Kasanke, Gifford Miller, Jonathan H. Raberg

“…The most recent retreat of glaciers on Baffin Island, Nunavut, has been since the Little Ice Age, due to anthropogenic warming. Retreating cold-based ice often uncovers ancient vegetation. …”

Climatic variability as a principal driver of primary production in the southernmost subalpine Rocky Mountain lake by Anna Shampain, Jill S. Baron, Peter R. Leavitt, Sarah A. Spaulding

“…The abundance of cyanobacteria, purple sulfur-reducing bacteria, and diatom pigments were elevated during the stable conditions of the Little Ice Age; these phototrophic groups declined in the late 1800s and reached a minimum by 1950. …”

Thermal state of permafrost in the high mountains of Mexico by Kenji Yoshikawa, Victor Soto, Guillermo Ontiveros-Gonzales, Samael Oliver Vagamontes, Hugo Delgado Granados, Lorenzo Vazquez-Selem, David Palacios

“…Some of the sporadic permafrost may still exist on the Little Ice Age rock glaciers, but most of the buried glacial ice between 4,500 and 5,000 m.a.s.l. is slowly decaying and not thermally stable as permafrost. …”

Central Asia Cold Case: Siberian Pine Fingers New Suspects in Growth Decline CA 1700 CE by David M. Meko, Dina F. Zhirnova, Liliana V. Belokopytova, Yulia A. Kholdaenko, Elena A. Babushkina, Nariman B. Mapitov, Eugene A. Vaganov

“…We conclude that stress from low summer temperatures in the Little Ice Age was likely exacerbated by tree damage associated with weather extremes, including infamous Mongolian “dzuds”, over 1695–1704. …”

Greening of Svalbard in the twentieth century driven by sea ice loss and glaciers retreat by Gianmarco Ingrosso, Chiara Ceccarelli, Federico Giglio, Patrizia Giordano, Jens Hefter, Leonardo Langone, Stefano Miserocchi, Gesine Mollenhauer, Alessio Nogarotto, Mathia Sabino, Tommaso Tesi

“…Here, we measured plant-derived biomarkers from an Arctic fjord sediment core as proxies for reconstructing past changes in tundra vegetation during the transition from the Little Ice Age to modern warming. Our findings revealed a rapid expansion of the tundra since the beginning of the twentieth century, largely coinciding with the decline of summer sea ice extent and glacier retreat. …”

Runoff responses to Atlantic multidecadal and Pacific decadal oscillations in China: Insights from the last millennium simulations by Yangyi Liu, Jie Chen, Lihua Xiong, Chong-Yu Xu

“…Taking Medieval Climate Anomaly (MCA) and Little Ice Age (LIA) as study periods and focusing on summer runoff in China, this study aims to investigate 1) the major time scales at which AMO/PDO affects runoff, and 2) the individual and coupled effects of AMO and PDO on runoff by using last millennium climate model simulations. …”

Fossil Diatoms Reveal Natural and Anthropogenic History of Jackson Lake (Wyoming, USA) by John Dilworth, Jeffery R. Stone, Kevin M. Yeager, J. Ryan Thigpen, Michael M. McGlue

“…The core spans the termination of the Little Ice Age and extends to the present day (∼1654–2019 CE). …”

Geomorphology and Sedimentology of a Rapidly Retreating Alpine Glacier: Insights From the Taschachferner, Tirol, Austria by D. P. Le Heron, P. Mejías Osorio, M. Heninger, B. J. Davies

“…The valley margins are dominated by several generations of lateral moraines, the most prominent of which corresponds to the 1852 Little Ice Age Maximum. A well-developed “hanging sandur” is observed immediately in front of the ice margin. …”

Reconstruction of climatic events from the 16th century in Transylvania: interdisciplinary analysis based on historical sources by Ovidiu Răzvan Gaceu, Tudor Caciora, Ștefan Baias, Cezar Morar, Mihai Dudaș, Marius Stupariu, Maria Maxim

“…IntroductionUnderstanding past climate variability is essential for interpreting current and future climate trends, particularly during defining climate periods for the past two millennia, such as the Little Ice Age, which had significant socio-economic impacts.MethodsThe present study uses an interdisciplinary approach, analyzing written documents such as chronicles, diaries, and official records to extract data related to climate events in the 16th century in Transylvania (on the current territory of Romania). …”

Nutrient cycling characteristics along a chronosequence of forest primary succession in the Hailuogou Glacier retreat area, eastern Tibetan Plateau by Danli Yang, Ji Luo, Shumiao Shu, Yan Hu, Hongsong Tang, Xuemei Li

“…Background The Hailuogou Glacier has been continuously retreating since the end of the Little Ice Age, resulting in a 125-year soil chronosequence and a complete primary forest succession sequence. …”
