Just like we read left to right, most weather systems move left to right (West to East). Right now however, the weather pattern is out of whack, moving East to West, creating a monster tropical heatwave for a big chunk of the U.S. WeatherNation Chief Meteorologist Paul Douglas has more on the rare retrograde weather…
Recently Doug asked: “…my question is, how far could this phenomenon go? What is the “end” state? Is it possible for example that we could find the jet stream staying in place for months at a time, years, decades? How wavy could this waviness become?” A main theme of Sea ice loss seems to be…
This video is part of a Climate Desk event “Climate Desk Live 06/06/13: The Alarming Science Behind Climate Change’s Increasingly Wild Weather” featuring top climate researcher Jennifer Francis. Watch the full event (including Stu Ostro on atmospheric thickness) here .

By Joe Romm / Climate Progress: Earlier this month, Chris Mooney moderated a terrific Climate Desk event featuring top climate researcher Jennifer Francis along with senior Weather Channel meteorologist (and former skeptic) Stu Ostro. Climate Desk summarizes their findings: Ostro’s observations suggest that global warming is increasing the atmosphere’s thickness, leading to stronger and more persistent ridges…

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…
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…
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…
Hurricanes, whose development tends to be inhibited by jet streams, may become more powerful and more frequent as the jet streams move away from the sub-tropical zones where hurricanes are born. Stanford, CA—The Earth’s jet streams, the high-altitude bands of fast winds that strongly influence the paths of storms and other weather systems, are shifting—possibly…
