"Scientists again urge Congress to act on warming",

"There is about 4 percent more water vapor in the atmosphere today than there was in 1970 because of warmer oceans and warmer air. This year, the United States has been pummeled with historic snowstorms (with 70 percent of the nation is snow covered today), Australia is suffering from torrential and repeated rain storms and floods, and there is wild weather elsewhere around the globe.

That's why we were so pleased reading the letter to Congress the National Academy of Sciences sent this week. The scientists strongly reasserted the validity of climate science and asking the members to lead a strong national response to climate change.

They said, "Climate change is not just an environmental threat but…also poses challenges to the U.S. economy, national security and public health."…" climate change is not the product of a belief system or ideology. Instead, it is based on scientific fact, and no amount of argument, coercion, or debate among talking heads in the media can alter the physics of climate change. …"There are no Democratic or Republican carbon dioxide molecules; they are all invisible and they all trap heat."…"Climate change deniers cloak themselves in scientific language,… Sometimes they present alternative hypotheses as an explanation of a particular point, as if the body of evidence were a house of cards standing or falling on one detail; but the edifice of climate science instead rests on a concrete foundation.

Arctic sea ice at a January low
The National Snow and Ice Data Center has observed the lowest amount of ice coverage in the Arctic in January since satellite records were started in 1979. Ice coverage was down by 19,300 square miles from the previously recorded low in 2006 and is 490,000 square miles below the 1979 to 2000 average. Ice coverage was also low in Hudson Bay, Hudson Strait and Davis Strait and the Labrador Sea is ice-free. Air temperatures in the Arctic were 4 to 11 degrees Fahrenheit warmer in January."
