Why Global Warming Should Keep You Awake at Night: Dr. Jennifer Francis Gives Chilling Testimony to Congress

Via Robertscribbler: In a July 18 testimony to Congress, Dr. Jennifer Francis, an atmospheric scientist from Rutgers and key innovator to understanding how climate change has brought about dangerous alterations to the Northern Hemisphere Jet Stream, provides five compelling reasons why we should all be quite concerned about human caused global warming. They include: 1.…

Estimating the permafrost-carbon feedback on global warming

A key uncertainty is the fraction of carbon that might be decomposed under anaerobic conditions – resulting potentially in methane emissions to the atmosphere. Given the high warming potential of methane, the overall magnitude of the permafrost-carbon feedback will depend strongly on this fraction. Thawing of permafrost and the associated release of carbon constitutes 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…

James Hansen explains Climate Change and Free Market Solution

39:00 min = topic Carbon fee  Climate Scientist Hansen Turns Activist, Advocates ‘Fee’ on Carbon Pollution Bloomberg: James Hansen, the former NASA climate scientist who first brought climate change to the attention of Congress in the 1980s, stepped down as head of the agency’s Goddard Institute for Space Studies last month. That hasn’t stopped him…

97 Percent of Peer-Reviewed Science Confirms Manmade Global Warming, Consensus Overwhelming

In the most comprehensive study to date, a new survey of over 12,000 peer-reviewed climate science papers has found a 97% consensus in the peer-reviewed literature that humans are causing global warming. http://skepticalscience.com/97-percent-consensus-cook-et-al-2013.html     A paper in the journal Environmental Research Letters yesterday found that the number of scientific papers rejecting the thesis that humans…

Tar-Sands Oil Makes Climate Change Unsolvable

By Alex Morales / Bloomberg: Exploiting oil and gas trapped in tar sands and shale threatens to make climate change“unsolvable,” said James Hansen, the former NASA scientist who raised concerns about global warming in the 1980s. Conventional reserves of oil, gas and coal already have more carbon embedded in them than is safe to burn without causing “dangerous” levels of…
