Dark Snow Project Chief Scientist Dr. Jason Box interviewed by Bill Maher on Real Time, on July 12, 2014. Peter Sinclair, noted: It’s difficult to keep up with, much less steer, an interview with someone as mercurial as Bill Maher, but Dr. Box does a decent job. He gives a good description of the “dark snow”…
Alfred-Wegener-Institut, 28 Mai 2014: Der Antarktische Eisschild hat zum Ende der letzten Eiszeit in kurzer Zeit sehr viel Eis verloren und damit den Meeresspiegel weltweit rasant um mehrere Meter ansteigen lassen. Mit ihrer Studie liefern die Wissenschaftler den ersten Beweis dafür, dass der Massenverlust des Antarktischen Eisschildes wesentlich dazu beigetragen hat, dass der Meeresspiegel am Ende…
By Laura Naranjo (NSIDC), first published January 31, 2014. In the following an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…
An Australian-led research team found that sea levels may rise much faster than previously predicted by models, because changes by disruptive westerly winds, weren’t taken into account. Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase. Related Each degree of global warming might ultimately raise…
NASA/JPL press release, May 12, 2014: A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea. The study presents…
Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere. CH4 Release The following studies explore the release of CH4 emissions in the Arctic region. OBSERVATION…
A new study paper out in nature (Nature Climate Change / 2014 / doi:10.1038/nclimate2159), explores why the rise of sea-level has slowed in the last decade. Unsurprisingly the slow-down coincidences with the observed climate hiatus (IPCC AR5, Ocean heat content uptake). Because heat is distributed differently, depending on the state of ENSO (between El Nino or La Nina). Abstract: Present-day sea-level…

NOAA: The most common metric for tracking changes in Arctic sea ice over time is sea ice extent. Extent approximates the sea ice you would see from a bird’s-eye view, and it has been declining at a rate of more than 14 percent per decade since satellite measurements began in 1979. If you were to…
