Senior officials from NASA, the National Science Foundation, the Department of Homeland Security and the Pentagon are to be briefed at the White House soon on the danger of a summer ice-free Arctic by 2015. This indicates that they are increasingly concerned about the international and domestic security implications of climate change. Senior scientific advisers at the meeting include 10 Arctic specialists, including University of Western Australia marine scientist Carlos Duarte. Earlier, Duarte warned that the Arctic summer sea ice was melting at a rate far faster than previously predicted, and could disappear by 2015 . He said: “The Arctic situation is snowballing” noting that the melting caused by global warming would, in turn, create conditions causing further, faster melting, adding, “This situation has the momentum of a runaway train.” Duarte co-authored a paper recently in Nature Climate Change documenting how “tipping elements” in the Arctic ecosystems leading to “abrupt changes” that would dramatically impact “the global earth system” had “already started up”. They concluded: “We are facing the first clear evidence of dangerous climate change.” New research suggests that Arctic summer sea ice loss is linked to extreme weather.
Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
