"90% Chance 2012 Will Be Warmest Year on Record for US"

"Continuing a hot trend, October was the fifth warmest across the globe since record keeping began in 1880. And climate scientists say it's likely, about 90 percent so, that 2012 will become the warmest year on record for the contiguous United States."

"The last 36 Octobers, including this one, have experienced global temperatures above the 20th-century average; in fact, the past 332 months have all shown above-average temperatures globally, according to a report by the National Oceanic and Atmospheric Administration (NOAA)."
