seasonal temperature and precipitation dynamics as key driver of permafrost changes in East Siberia. To this end, caves and permafrost exposure will be studied in East Siberia along a transect from the [...] different types of relict permafrost ice, (iii) Deduce changes in seasonality, moisture dynamics, and continentality based on results from objectives 1 and 2, and corresponding permafrost response to climate [...] orientation of research projects include scientific applications of stable isotope methods in permafrost research, palaeoclimate studies, by also in the fields of limnology, hydrology, ecology and glaciology

Spitsbergen. We had two main goals: Firstly, we maintained the Bayelva permafrost observatory where multiple air, snow, soil, and permafrost parameters have been measured since 1998. And secondly, we measured [...] elevations using a high-accuracy GPS antenna to estimate surface subsidence resulting from thawing permafrost. In addition, we visited research sites of local and international partners and discussed scientific

The thawing of permafrost poses various endangerments to the Arctic environment and the livelihoods of people. An international team examined the social risks for Arctic regions and identified five key risks related to infrastructure, transport and supply, water quality, food security and health.

Permafrost
The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena [...] every year, roughly 15 metres of the riverbanks crumble away. In addition, the carbon stored in the permafrost could worsen the greenhouse effect.

Climate and Vegetation
The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing
