Affected by ice free seas, polar bears are increasingly visiting human villages and adding human waste to their diet. So what are Russian Arctic bears eating? Researchers decided to analyse bear poo to measure natural vs human waste sources of food. Arctic sea ice melt has left polar bears unable to feed on their natural…

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…
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…
Soviet and Russian perspectives on geoengineering and climate management
With geoengineering being a hot topic in climate change discussions, Jonathan Oldfield and Marianna Poborezhskaya reviewed the history and current thinking from both Soviet and Russian perspectives. During Soviet history, discussions mirrored other countries about human influence on climate change such as stratospheric sulfur aerosols to mitigate the effect. Even within the 1950s Soviet scientists…
Seasonal methane across northen Siberian waters
Siberian scientists recently analysed how much methane was stored in the Lena River, Tiksi Bay and .Lake Golzovoye because methane levels in water are not as well known. Between 2001-17 the atmospheric methane increased to 1932 ppb, recorded at Tiksi Hydrometeorological Observatory. They wanted to investigate the relationship between warmer water temperatures and increased methane…
Ice jams and models along the Volga river
Ice is one of the leading causes of damage to infrastructure from water factors including flooding, ice blockages and hanging ice: In 2020, The Russian Federal Service for Hydrometeorology and Environmental Monitoring (Roshydromet) recorded 1,000 dangerous hydrometeorological phenomena in Russia (97 phenomena more than in 2019), of which 372 phenomena caused significant damage to critical…
