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…

Ozone Levels Drop When Hurricanes Are Strengthening

Hurricanes and Ozone June 11, 2005 Ozone levels drop when a hurricane is intensifying. Xiaolei Zou and Yonghui Wu, researchers at Florida State University found that variations of ozone levels from the surface to the upper atmosphere are closely related to the formation, intensification and movement of a hurricane. They studied ozone levels in 12 hurricanes…

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…

Weird weather might just wake feeble politicians up to climate change

The Guardian: Meteorologists are debating our role in bizarre weather events. We have the technology for change, but not the political will On Monday, Amory Lovins, physicist, environmentalist, and unassuming colossus of the green movement, appeared in London to talk about energy use. I mention this in the context of the Guardian’s story that meteorologists…

The state of the climate and national security

The release of huge quantities of previously stored “multiyear/deep layer” carbon deposite and equivalent greenhouse gases (CO2/CH4/N2O, from soil and water) can act like a trigger to boot the earth systems. This boot begins initially with a transition phase depending on the rate of emissions and in further development creates several large scale carbon excursions…

Pentagon bracing for public dissent over climate and energy shocks

NSA Prism is motivated in part by fears that environmentally-linked disasters could spur anti-government activism The Guardian: Top secret US National Security Agency (NSA) documents disclosed by the Guardian have shocked the world with revelations of a comprehensive US-based surveillance system with direct access to Facebook, Apple, Google, Microsoft and other tech giants. New Zealandcourt…

The N Hemisphere’s Atmospheric Circulation Has Collapsed Creating a Persistent Polar Cyclone

By FishOutOfWater / DailyKos: 500mb heights Normal for May 21 to June 6; 1980-2010 Average 500mb heights for May 21 to June 6 2013 A sudden stratospheric warming split the polar vortex in two in mid-January. Since then, the northern hemisphere’s atmospheric circulation has been behaving very strangely. An area of extreme high pressure formed…

How Hot will it Get?

The latest projections about the extent of planetary warming and the dire consequences of our growing carbon imbalance. Series: “Science at the Theater” [Science] A special Earth Day edition of Science at the Theater —”How Hot Will It Get?” — Featuring presentations by Lab climate scientists Bill Collins, Margaret Torn, Michael Wehner, and Jeff Chambers,…

Permafrost: The Tipping Time Bomb

“If we can limit our emissions, then the permafrost region will release less carbon to the atmosphere, there is a curve – it’s not a all or nothing question.” Ben Abbott One of the most feared of climate change “feedbacks” is the potential release of greenhouse gases by melting arctic permafrost soils. New research indicates…

Can Wind Turbines Withstand E5 Tornadoes?

SustainableBusiness.com News: Did you ever wonder how wind turbines would withstand extreme weather events like tornadoes and hurricanes?

When the widest tornado ever measured on Earth flattened parts of Oklahoma this month that was a good time to find out. It was rated E5 – the most severe possible – and only the eighth of this magnitude since 1950 in the tornado-prone state. Two smallish wind turbines, which were being used for educational purposes at Canadian Valley Technology Center (CVTC) took a direct hit from the 295 per hour winds.
