Prepare For 6 to 10 Degree F Rise, Says Ex IPCC Head

The world has missed the chance to keep greenhouse gas emissions below the level needed to prevent the temperature climbing above 4 degrees Fahrenheit, according to the British scientist Sir Robert Watson, who used to chair the most reputable group of scientists studying climate change in the world, the Intergovernmental Panel on Climate Change, reports Alex Kirby at Climate News Network. He chaired the group from 1997 to 2002, when the US pressured his removal. Watson says there is a 50-50 chance of preventing global average temperatures rising more than 6 degrees Fahrenheit but a 10 degree Fahrenheit rise is also possible.  That would mean the Earth warming more than it has since the end of the last Ice Age. He said: “All the evidence, in my opinion, suggests we’re on our way to a [6 to 10 degree F] world… I’m very, very nervous about [proposed geo-engineering solutions]… There are cost-effective and equitable solutions to address climate change, but political will and moral leadership is needed… changes in policies, practices and technologies required are substantial and not currently under way.”

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . 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.
