AAAS: Climate Change Threatens World With Irreversible Changes

AAAS: Climate Change Threatens World With Irreversible Changes warn scientists of the American Association for the Advancement of Science, reports Suzanne Goldenberg at the UK Guardian. AAAS, which rarely makes policy statements, is urging the US to act swiftly to reduce carbon emissions and lower risks of climate catastrophe. Says the new report, What We Know: “We are at risk of pushing our climate system toward abrupt, unpredictable, and potentially irreversible changes with highly damaging impacts … We can think of this as sudden climate brake and steering failure where the problem and its consequences are no longer something we can control. In climate terms, abrupt change means change occurring over periods as short as decades or even years.”

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 this year!) 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.
