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…

The Independent, December 13, 2011: Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region. The scale and volume of the methane release has astonished the head…

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…

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…
