Thawing permafrost dots Siberia with rash of mounds

In eastern Siberia near the town of Churapcha, a rapid thaw of permafrost is producing small mounds called bylars, altering the landscape and damaging buildings.
This thaw results from rising temperatures in Yakutia, which have increased by about 1.5 degrees Celsius over 30 years, with some areas warming up to two degrees.
The thaw melts underground polygonal ice, creating distinctive hillocks up to one meter high that appear even in urban areas, causing building walls to crack and subside.
Alexander Makarov explained that even small temperature rises reduce permafrost depth, and data confirm 2023 and 2024 were the hottest years in over 120,000 years globally.
The thaw releases greenhouse gases and ancient bacteria, posing environmental and health risks, exemplified by a 2016 anthrax death linked to thawed spores preserved in ice.
