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…

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…

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…

Video: Lake El’gygytgyn, Pleistocene super-Interglacials and Arctic warmth

John Mason / Skeptical Science: Here is a must-see 2012 presentation by Julie Brigham-Grette of the University of Massachusetts Amherst, covering the research her team has been doing into Lake El’gygytgyn (pronouned El-Guh-Git-Kin), a water-filled meteor crater in Arctic Russia that came into being after the impact of a ~1km diameter space-rock, 3.6 million years ago.…
