Greenland Ice Core CO2 Concentrations Deserve Reconsideration

Guest post by Renee Hannon IntroductionIce cores datasets are important tools when reconstructing Earth’s paleoclimate. Antarctic ice core data are routinely used as proxies for past CO2 concentrations. This is because twenty years ago scientists theorized Greenland ice core CO2 data was unreliable since CO2 trapped in air bubbles had potentially been altered by in-situ…

Greenland ice losses rising faster than expected

University of Leeds Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change’s high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100. A team of 96 polar scientists from 50 international organisations have produced the most complete…

Greenland’s ‘Record Temperature’ denied – the data was wrong

From the “But, but, wait! Our algorithms can adjust for that!” department comes this tale of alarmist woe. Greenland’s all-time record temperature wasn’t a record at all, and it never got above freezing there. First, the wailing from news media: NYT: https://www.nytimes.com/2019/08/02/climate/european-heatwave-climate-change.html WAPO: https://www.washingtonpost.com/news/capital-weather-gang/wp/2016/06/10/greenland-witnessed-its-highest-june-temperature-ever-recorded-on-thursday/ Climate Progress: https://thinkprogress.org/greenland-hits-record-75-f-sets-melt-record-as-globe-aims-at-hottest-year-e34e534e533e/ Polar Portal: http://polarportal.dk/en/news/news/record-high-temperature-for-june-in-greenland/ Now from the Danish Meteorological…

Greenland Endures

Guest Post by Willis Eschenbach Charles the Moderator has been doing a fantastic job of keeping WUWT humming along, and deserves everyone’s thanks. Today he sent me an interesting article thinking I might want to comment on it. It has the usual kind of alarmist headline, viz: Greenland lost 11 billion tons of surface ice…

Inconvenient: NASA says a Greenland glacier did an about-face – growing again

“…scientists were so shocked to find the change.” From NASA JPL: Cold Water Currently Slowing Fastest Thinning Greenland Glacier NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean…
