Abstract The changes in the main climate variables that determine the atmospheric hydrological cycle and the hydrological regime of land (surface air temperature and precipitation) are considered for the first decades of the 21st century, as well as in comparison with the most significant changes during the 20th century. Regional changes in seasonal climate statistics…

Heartwood and carbon in NW Russian pine trees
Heartwood (HW) has a major proportion of a tree trunk, compared with its outer sapwood (SW). Researchers investigated the carbon accumulation to understand the depths of carbon sequestration in pine species in north-western Russia. They mentioned that 64% of the forests of Russian Karelia are Scots Pine which they compared across lingonberry (30% Karelia, 42%…
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…
Carbon update from the Ladoga polygon
The Ladoga polygon is part of a network of carbon monitoring sites, with Ladoga providing data for this north-west region of Russia. It stores large volumes of carbon in soils, approx 208 tC/ha which is the largest volume outside of permafrost affected soil. The region has not had any significant agricultural activity for over 40…
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…
Understanding rain, snow and cyclones across the Barents Sea
[Ed. Alexander Kislov and his team are some of Russia’s leading climate scientists] Interest in the effect of warming temperatures in the Arctic continues to grow, with researchers studying a range of impacts such as reduced sea ice, animal migration, flora changes and overall adaptation. However building an overall picture takes multiple projects and multiple…
Feeling the burn in the Volga
Warmer climates have increased the frequency and volume of forest fires across Russia, even in areas which have snow cover. About 98% of forest fires in populated Russia were estimated to be caused by human activity and in more remote areas, approximately 50% caused by thunderstorms and lightening. The researchers reviewed the risks and effect…
Climate change impact on river basins in Ukraine 2020
The researchers used six models comparing precipitation and drought based on river levels using RCP 2.6 and RCP 8.5 scenarios. Their predictions show a decrease in water in most of the eight main river basins, particularly between 2040 – 2070. The greatest reductions by the end of the century are predicted for Pripyat, Southern bug…
Catching raindrops in Primorye
Scientists at the Russian Academy of Sciences have developed mathematical models to predict flooding effects and assist with an action plan. To develop and test their models, they used flooding data from flooding in Primorye in 2001. They included the flooding area, water level, temperature and velocity. They also included human and animal populations in…
