Abstract Climate risks pose a threat to the economy and the society, making their accurate assessment crucial for effective adaptation strategies. However, such estimates are complicated due to incomplete data on the potential risk-related damages. In this study, we apply a simplified heuristic approach using the hazard-exposure-vulnerability framework to assess climate risks in Russia. We…

Impact on permafrost layers from wildfires
Multi-authored article including some Russian contributions. They were interested in the thickness of the active permafrost layer and have combined 52,566 data records which others can use for modelling further impacts. Abstract: As the northern high-latitude permafrost zone experiences accelerated warming, permafrost has become vulnerable to widespread thaw. Simultaneously, wildfire activity across northern boreal forest…
Measuring freezing and thawing in the Kola peatlands with GPR
The active layer of permafrost which freezes and thaws is seasonally monitored using ground-penetrating radar (GPR) for variation in activity and thickness, especially in response to recent climate change. Ryazantsev wanted to find out whether GPR can provide useful information about thermal factors such as soil temperature change, thermal insulation and thermal conductivity. Remote sensing…
Pleistocene Park creators identify 3000 yr old Siberian weather using mummified wood
Nikita and Sergey Zimov of Pleistocene Park in Sakha Republic of Russia, co-authored a study reconstructing Holocene weather conditions. This will help predict the effects of climate change in today’s Russian Arctic. Even Siberian permafrost regions have seasonal variation, especially summer and winter cycles. Mean average annual temperatures and general mean average conditions were previously…
What is in defrosted Russian Arctic ice?
Carbon deposits in thawing permafrost include widely reported methane gases released as bubbles and present in craters across Siberia. Scientists wanted to find out more about the greenhouse emissions and what was in the defrosted ground ice including dissolved organic matter (DOM) and particulate organic matter (POM). They studied four locations across the Russian arctic…
Climate challenges for small indigenous groups in the Russian Arctic
[Ed. for further exploration of the topic, Matvienko cites 23 research studies from the last fifteen years included at the end of his article] Roshydromet’s data shows that the average annual air temperature in the Russian Arctic has warmed faster than other parts of the world. (Matvienko, 2023), affecting indigenous (Nenet, Evenk, Chutki) populations. These…
Highway to decomposed organic matter – heavy metals in Central Siberian forests
Mining and potential toxic elements (PTE) causing soil contamination is an internationally researched issue due to the transfer and resilience of the metallic elements in the soil affecting ecosystem health. Metals move from mining dump sites either as airborne elements or through plant root structures into the soil. The researchers studied the Vilyui plain on…
Great Norilsk Expedition results in 2023
In 2020, scientists from across 14 branches of the Russian Academy of Sciences began the expedition in Taymyr. They are assessing the state of Arctic ecosystems in the area. Early results of impacts on Arctic waters, via TASS and the Institute of Biophysics (EN) at the Siberian Branch of the Russian Academy of Sciences (SB-RAS);…
Understanding hydrological pressures caused by melting permafrost
Researchers evaluated the current network of hydrometeorological observation across the permafrost. They wanted to find out how to improve statistical approaches for modelling engineering design and hydrological impact from melting permafrost such as increased flooding. They reviewed the distribution of ground temperature stations and hydrological gauges that currently measure streamflow discharge, where permafrost is covering…
Salt on the move in the permafrost
Researchers at Skoltech wanted to understand more about the effect of pressure and temperature on salt distribution in permafrost that contains hydrates and permafrost that doesn’t. Existing research does not model salt diffusion and transportation in permafrost thawing. They simulated experiments reproducing the degrading permafrost in laboratory conditions by changing the temperature and pressure whilst…
