Arctic Becoming More Volatile With Faster Warming – Report

Global warming is rapidly driving the Arctic into a volatile state characterized by massive reductions in sea ice and snow cover, more extensive melting of the Greenland ice sheet, and a host of biological changes, according to a  recent comprehensive report published by NOAA, the National Oceanic and Atmospheric Administration, reports Andrew Freedman at Climate Central. The seventh annual “Arctic Report Card” summarizes the latest scientific observations in the fastest-warming region on Earth. Members of the international team that produced the report said Arctic climate change is likely to have broad and sweeping repercussions well outside of the Far North. Scientists who contributed to the report described an Arctic that may already have passed a key threshold into a new state, in which even modestly warm years have major impacts. “If we are not already there, we are surely on the verge of seeing a new Arctic,” said Dartmouth University researcher and sea ice expert Don Perovich. “The Arctic acts as a thermostat for the global climate,” he said. “We can expect to see Arctic change have global environmental and socioeconomic consequences.”

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.
