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…

Changing Jet Streams May Alter Paths of Storms and Hurricanes

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…

Arctic Amplification and Extreme Weather

The “Arctic Paradox” was coined during recent winters when speculations arose that the dramatic changes in the Arctic may be linked to severe snowstorms and cold temperatures in mid-latitudes, particularly along the U.S. east coast and in Europe. Recent studies have illuminated these linkages. Evidence is presented for a physical mechanism connecting Arctic Amplification —…

Lesson: Arctic Sea Ice Decline

Jennifer Francis, Rutgers University – assesses the broad topic of the Arctic Sea Ice Decline and explains seasonal impacts. Observations, especially since the 1950’s, explain how the “Arctic Amplification” leads to rapid sea ice changes during the summer month. Much more ridging in North America during the winter. And this affects weather patterns, because a…

Extreme Jet Stream Pattern Triggers Historic European Floods

Dr. Jeff Masters / Wunderground: A historic multi-billion dollar flood disaster has killed at least eighteen people in Central Europe after record flooding unprecedented since the Middle Ages hit major rivers in Austria, the Czech Republic, Germany, Poland and Slovakia over the past two weeks. The Danube River in Passau, Germany hit the highest level…

Climate, Ice, and Weather Whiplash

Peter Sinclair: Last year I spoke to Dr. Jeff Masters and Dr. Jennifer Francis about the emerging research linking “weather whiplash” events, back to back extremes of all  types that seem to have become our new normal, and the disappearance of arctic ice. This year, the extremes continue. I’ve revisited Dr. Francis on the issue, to talk about what…

Humid air and the Jet Stream help to fuel more intense thunderstorms/tornadoes

“The fuel for the more intense storms would be the predicted warming of the Earth caused by the burning of fossil fuels that release greenhouse gases.” A combination of a slower Jet Stream (see video for explanation and study) and a more humid atmosphere increase the likelihood for a more intense thunderstorm environment. This conclusion…

Jennifer Francis: Wacky Weather and disappearing Arctic Sea Ice are they connected?

Dr. Jennifer Francis – Rutgers University “Extreme weather events are increasing in frequency and intensity all around the northern hemisphere.” Concurrently, Arctic sea ice is in an accelerating decline, the entire surface of Greenland melted for the first time in at least 150 years, glaciers are disappearing around the world, and snow cover on Arctic…

Does Arctic Amplification Fuel Extreme Weather in Mid-Latitudes?

Jennifer Francis, Rutgers University, 25 January 2012. The “Arctic Paradox” was coined during recent winters when speculations arose that the dramatic changes in the Arctic may be linked to severe snowstorms and cold temperatures in mid-latitudes, particularly along the U.S. east coast and in Europe. Recent studies have illuminated these linkages. Evidence is presented for…
