summarizes key findings from NOAA.

See:http://www.pewclimate.org/blog/gulle...est-year-recor....

Every January, NOAA s National Climatic Data Center provides an expert
analysis of the previous year s climate. This puts the extreme weather
of 2010 into a broader context. The record warmth of the past year adds
to the huge body of evidence that the earth continues to warm.

Using extrema to find a trend is provably invalid, and the differences
between a tie and a winner her are statistically insignificant.

HOWEVER, . . .

Please note that these data show no statistically significant recent
downturn. The globe continues to warm.

Also note the observation, "Global snow cover was the lowest on
record." Models are showing the Northern Hemisphere's climate on the
edge of a ice albedo feedback tipping point.
