May 2013 Earth’s 3rd Warmest May; Central European Floods Cost $22 Billion

By Jeff Masters / Wunderground: May 2013 was the globe’s 3rd warmest May since records began in 1880, according to NOAA’s National Climatic Data Center (NCDC). NASA rated it the 10th warmest May on record. The year-to-date period of January – May has been the 8th warmest such period on record. May 2013 global land…

Secrets of Abrupt Climate Shifts revisited

The understanding of the puzzle about what is going on with our climate system and possible implications improved recently. Let’s begin with going back to 2006, here i quote an excerpt from the blog post “Revealed: Secrets of Abrupt Climate Shifts” via RealClimate, describing more robust understanding of the bipolar / see-saw mechanism of the…

Exceptional 2012 Greenland Ice Melt Caused By Jet Stream Changes That May Be Driven By Global Warming

By Joe Romm / Climate Progress: New research finds that “unusual changes in atmospheric jet stream circulation caused the exceptional surface melt of the Greenland Ice Sheet (GrIS) in summer 2012.” Prof. Jennifer Francis tells me these changes are consistent with those caused by warming-driven “Arctic Amplification.” And that means GrIS may melt faster than…

Research closes gap between Warming and CO2 Rise

Feedbacks in the climate system – in which warming is linked to natural CO2 increase, driving further warming – may operate faster than previously thought. ACE CRC: Researchers use Antarctic and Greenland ice cores to examine temperature and CO2 changes during the largest natural climate change in Earth’s recent climate history: the warming out of…
