A study currently under review in Climate of the Past has reported that Arctic Siberia experienced summer temperatures up to 10 degree Celsius warmer than today during the Last Interglacial period, approximately 115,000 to 130,000 years ago. Researchers have drawn these conclusions from sediment cores and fossil remains, highlighting how polar ecosystems responded to heightened warmth in that era. The findings have been presented by Dr Lutz Schirrmeister and colleagues from the Helmholtz Center for Polar and Marine Research in .

Arctic Warming Amplified by Ice Albedo 2q1f5u

solar radiation reflected into space and enhances warming. The research team conducted their fieldwork in coastal sections along Siberia's Dmitry Laptev Strait, where permafrost-related landscapes have been preserved.

As per reports, the unique thermokarst topography in the area, formed by thawing ice-rich permafrost, provided insights into past climate conditions. Layers of peat, clays, and silts were analysed from sediment cores collected between 1999 and 2014. Fossil evidence, including pollen, insects, and mollusks, allowed the team to reconstruct historical environments, revealing significant shifts in vegetation and climate over time.

Vegetation Shifts and Temperature Changes 4h5h4b

Sources have indicated that grasslands and tundra-steppe dominated the region during the early Last Interglacial, giving way to birch and larch forests at its peak. Fossilised plant material suggests mean summer temperatures reached 15 degree Celsius, significantly higher than the current average of 3 degree Celsius. Winter temperatures during this period are estimated at -38 degree Celsius, compared to today's average of -34 degree Celsius.

It was noted that while the Last Interglacial primarily affected summer temperatures, ongoing anthropogenic climate change is expected to impact winters more significantly. Dr Schirrmeister emphasised the importance of understanding Earth's sensitivity to rising temperatures, in his statement, as the melting of Arctic permafrost and sea ice continues to be observed today.
