Share this…FacebookTwitter Image: NASA (public domain) By Die kalte Sonne Do you remember the wild story that cold winters in Central Europe are supposedly a consequence of the Arctic turbo-heating? A great sideshow hypothesis in those years when winters were suddenly colder than expected. A study by Dai & Song 2020 has now brought the idea […]

Share this…FacebookTwitterToday, the region north of Svalbard is encrusted with sea ice for all but a few weeks per year and summer sea surface temperatures (SSTs) hover near 0°C. Scientists (Brice et al., 2020) have determined this same region had sea ice-free conditions last about 10 months per year while SSTs reached 4°C just ~4100 […]

Share this…FacebookTwitterDuring the Early Holocene, when CO2 levels lingered near 260 ppm, ice core records suggest surface temperatures in Iceland were about 3°C warmer than today. Iceland’s extensive lakes and glaciers topography provides a verifiable history of the region’s paleoclimates. For example, scientists can infer summer temperatures 3°C warmer than today in Iceland to account […]

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…FacebookTwitterScientists (Syring et al., 2020) find almost sea ice-free conditions pervaded a much warmer northern Greenland region during the Early Holocene. Arctic sea ice extent has “continuously” grown for ~4800 years, with modern conditions a bit lower than the peak of the last few centuries. Image Source: Syring et al., 2020 In a new […]

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…FacebookTwitterA new 800-year reconstruction of Western Arctic Ocean sea ice variability (Porter et al., 2019) indicates the recent centuries (and decades) of sea ice coverage are the most extensive of the period, with no significant net change in the last 200 years. There was no ice cover in the Western Arctic for about 2 […]

Share this…FacebookTwitterA new reconstruction of Arctic (NW Greenland) sea ice cover (Caron et al., 2019) reveals modern day sea ice is present multiple months longer than almost any time in the last 8000 years…and today’s summer sea surface temperatures s are among the coldest of the Holocene. Yet another new study (Caron et al., 2019) […]
