White House warned on imminent Arctic ice death spiral
National security officials worried by rapid loss of Arctic summer sea ice overlook threat of permanent global food shortages
Senior US government officials are to be briefed at the White House this week on the danger of an ice-free Arctic in the summer within two years.
The meeting, hosted by the Office of Science and Technology Policy within the Executive Office of the President at the White House, is being organised by the Joint Office for Science Support (JOSS) of the University Corporation for Atmospheric Research (UCAR) on behalf of the Interagency Arctic Research Policy Committee (IARPC). The IARPC, charged with coordinating federal research on the Arctic Ocean, is chaired by the National Science Foundation, and includes among its members Nasa, the US Department of Homeland Security and the Pentagon.
This is the latest indication that US officials are increasingly concerned about the international and domestic security implications of climate change.
Senior scientists advising the US government at the meeting include 10 Arctic specialists, including marine scientist Prof Carlos Duarte, director of the Oceans Institute at the University of Western Australia.
"The Arctic situation is snowballing: dangerous changes in the Arctic derived from accumulated anthropogenic green house gases lead to more activities conducive to further greenhouse gas emissions. This situation has the momentum of a runaway train."
"The loss of Arctic summer sea ice and the rapid warming of the Far North are altering the jet stream over North America, Europe, and Russia. Scientists are now just beginning to understand how these profound shifts may be increasing the likelihood of more persistent and extreme weather."
