2 weeks agoDeepest-ever rock core extracted from under Antarctic ice sheet
Preliminary dating, based on the presence of fossilized algae that only existed during specific geological periods, suggests that the core represents an archive of the past 23 million years. This includes periods when Earth's average surface temperature was hotter than today's - and higher than the temperature projected for 2100 under current global climate policies. The core was retrieved as part of the Sensitivity of the West Antarctic Ice Sheet to 2 °C (SWAIS2C) project.
