Share this…FacebookTwitterSeveral new studies use evidence from temperature-sensitive plant species and megafauna remains to reconstruct an Arctic climate that was 6°C to 22°C warmer than today when CO2 concentrations lingered near 300 ppm. Navigating the Arctic Ocean William Barentsz discovered Arctic Svalbard as he sailed through an open-water Arctic Ocean using a wooden boat in […]

Share this…FacebookTwitterThe perspective that polar bears  are endangered by global warming because reduced sea ice limits their seal-hunting opportunities is contradicted by observations of (a) polar bears thriving (body condition) during melt season, and (b) no trends in reduced seal consumption by polar bears in the 21st century. From the 1880s to 1940s, the Arctic’s […]

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 […]

There was no ice cover in the Western Arctic for about 2 […]

About 8,000 to 10,000 years ago, this region was 6°C warmer than today. Consequently, the region’s glaciers were much smaller (or non-existent) at […]
