The role of seasonality is indisputable in climate and ecosystem dynamics. Seasonal
temperature and precipitation variability are of vital importance for the availability of food …

Abstract Late Pleistocene and Holocene ground ice are common throughout the Arctic.
Some forms of relict ground ice preserve local meteoric water, and their stable oxygen‐and …

Ground ice melt caused by climate-induced permafrost degradation may trigger significant
ecological change, damage infrastructure, and alter biogeochemical cycles. The …

Reconstructions of global hydroclimate during the Common Era (CE; the past∼ 2000 years)
are important for providing context for current and future global environmental change …

Dating of ancient permafrost is essential for understanding long-term permafrost stability and
interpreting palaeoenvironmental conditions but presents substantial challenges to …

The propagation of joints and fissures, included by the frost heaving pressure arising from
the water-ice phase transition is considered as frost wedging. This process is widely …

The physical and chemical consequences of massive ground ice (wedges) melt upon
permafrost thaw is one of the central issues of environmental research linked to climate …

Global surface temperature changes and their drivers during the Holocene Epoch remain
controversial. Syntheses of proxy data indicate that global mean annual temperature …

Stable isotopes (δ18O, δD) of wedge ice hold potential to reconstruct past winter climate
conditions. Here, we present records of the marine isotope stages (MIS) 3 and 2 including …

Ice wedges in the Yana Highlands of interior Yakutia–the most continental region of the
Northern Hemisphere–were investigated to elucidate changes in winter climate and …
