Siberia’s Lost Mega-Lakes and Craters Reshaping Arctic Landscape

Researchers from the Karpinsky Russian Geological Research Institute have presented evidence suggesting that Siberia once hosted vast lakes comparable in scale to the Caspian Sea. Their defining characteristic, however, lay not merely in size but in their climatic influence. According to scientists, the enormous mass of cold water acted as a natural regulator, significantly cooling surrounding regions. Today, these ancient reservoirs have vanished, leaving behind only thick layers of bottom sediments. The cooling mechanism they once provided no longer exists. From Vanished Lakes to Giant Craters Another striking phenomenon attracting scientific attention involves giant craters appearing across Siberian territories rich in natural gas deposits. Some of these formations reach up to thirty meters in diameter and fifty meters in depth.
