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 […]

Share this…FacebookTwitterAt XR and FFF rallies, speakers like telling outright lies with the aim of trying to get the masses of people to stampede in mass panic and blind anger. One of these activists in Germany is Carola Rackete, reports Michael Krüger here at Science Skeptical. Rackete, the award-winning refugee rescuer and sea vessel captain, […]

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 […]

Yet another new study (Caron et al., 2019) […]

According to peer-reviewed science, Sweden was at least 3°C warmer than it is today about 6000 to 9000 years ago, when CO2 concentrations lingered around 265 ppm. At 410 ppm CO2, 21st century Sweden is colder now than almost any time in the last 9000 years. Image Source: Grudd, […]

Share this…FacebookTwitterCO2 concentrations have risen from 310 ppm to 410 ppm since the 1930s. However, there has been no net change in Arctic or Greenland temperatures during these last 90 years. During the Pliocene, CO2 also ranged between about 300-400 ppm, but the Arctic was 15-22°C warmer and sea levels 25 meters higher than today. […]

Share this…FacebookTwitterGreenland’s ice sheet mass losses have significantly decelerated since 2013 – a reversal from the rapid retreat from the 1990s to 2012 driven by cloud forcing and the NAO (Ruan et al., 2019). The post-2013 “relatively stable” ice sheet even gained mass during 2017-’18 (Andersen et al., 2019). Ruan et al., 2019 Decelerated […]
