Share this…FacebookTwitterScientists find three Arctic (Svalbard) lakes were all ~7°C warmer than they are now about 10,000 years ago – when CO2 concentrations were only 260 ppm. According to a just-published Geophysical Research Letters paper (van der Bilt et al., 2019), not only were surface temperatures 7°C warmer than today in High Arctic Svalbard due […]

Share this…FacebookTwitterThe Arctic’s western Barents Sea (Storfjordrenna) surface temperatures now range between 2-4°C. Sea ice persists in the region for 10 months of the year. A new study finds this same region was sea ice-free, 10°C warmer than today (13°C), and SSTs rapidly rose and fell by degrees C per century during the mid-Holocene. The […]

Share this…FacebookTwitter For over 40 years (1961-2002), the Greenland ice sheet cooled, thickened, and gained mass just as anthropogenic CO2 emissions were sharply rising. Image Source: Mikkelsen et al., 2018 According to Greenland ice sheet instrumental records, there was a dramatic cooling trend during summer months from the late 1980s to early 2000s (Chylek et […]
