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…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 […]

Share this…FacebookTwitterIn recent decades, North American glaciers have advanced by many kilometers and buried forests in ice in the same regions where glaciers have receded and uncovered Medieval-era forests. Image Source: Davi et al., 2019 Ancient forests buried beneath ice for the last ~1,000 years began “popping out from under southern Alaska’s Mendenhall Glacier” and […]

Share this…FacebookTwitterIn recent decades, the Earth’s seas have been rising at a rate of under 0.8 mm/year (8 cm per century) according to estimations of the sum of contributions to sea level rise. In contrast, sea levels rose at rates of more than 40 mm/year ~10,000 years ago. Relative sea level rise can be calculated […]

Share this…FacebookTwitterMost of the ice currently melting on Greenland only formed during the last few hundred years. Image Source: Mikkelson et al., 2018 A new paper (Axford et al., 2019) reveals NW Greenland’s “outlet glaciers were smaller than today from ~9.4 to 0.2 ka BP” (9,400 to 200 years before 1950), and that “most of […]

Share this…FacebookTwitterGeothermal heat flux can foment upper mantle temperature anomalies of 800–1000 °C, and these extreme heat intensities have been found to stretch across 500 km of central-east Greenland. This could result in “a significant contribution of ice melt to the ice-drainage system of Greenland” (Artemieva et al., 2019). Evidence of more than 100,000 formerly or […]

Image: foto.webcam.eu “Strongest growth in 20 years” ZAMG confirmed that last winter, the glaciers in the Hohe Tauern have grown more strongly than they have for 20 years. Austria’s ZAMG meteorological institute reminds, however, that the […]

Share this…FacebookTwitterIn the first 5½ months of 2019, over 200 scientific papers have been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and ²²²²mainstream media sources.

Share this…FacebookTwitterA new analysis of recent trends for the Greenland ice sheet reveals that since 2012 there has been an abrupt slowing of melt rates and a trend reversal to cooling and ice growth. • In 2018, 26 of Greenland’s 47 largest glaciers were either stable or grew in size. • Overall, the 47 glaciers […]
