T: is for trouble with the arctic ice

The results of a new Arctic survey shows that North Pole ice is melting faster than previously projected and scientists at Cambridge University predict the Arctic ocean will be largely ice-free during within the next ten years. Earlier this year, British explorer Pen Hadow and his team trekked for three months across the frozen Arctic Ocean, taking measurements and recording observations about the ice. "We'd been led to believe that we would encounter a good proportion, of this older, thicker, technically multi-year ice that's been around for a few years and just gets thicker and thicker," he said. "We actually found there wasn't any multi-year ice at all." Satellite observation and submarine surveys over the past few years had shown less ice in the polar region, but the recent measurements show the loss is more pronounced than previously thought. "We're looking at 80 percent roughly loss of ice cover on the Arctic Ocean in 10 years, and 100 percent loss in nearer 20 years," said Hadow. "The more you lose, the more open water is created, the more warming goes on in that open water during the summer, the less ice forms in the winter, the more melt there is the following summer," he said. "It becomes a breakdown process where everything ends up accelerating until it's all gone." "The carbon that we've put into the atmosphere keeps having a warming effect for 100 years, so we have to cut back rapidly now, because it will take a long time, there's a flywheel effect, it will take a long time to work its way through into a response by the atmosphere. We can't switch off global warming by being good in the future, we have to start being good now," he said.

Now is the time for a rescue plan before it is too late. Maybe somebody should inform Ms. Palin and that is a F.A.C.T.
