Warming update
Satellite data: World warming by 0.2 degrees Fahrenheit per decade.
Despite widspread cooling across the tropical Pacific, the worldwide temperature once again was well-above long-term averages in 2011.
According to satellite data released this afternoon by NASA's John Christy at the University of Alabama, the 2011 temperature was 0.27 degrees Fahrenheit over the 33-year average.
That made it the ninth-warmest year in the satellite period of record, but not as toasty as 2011, 0.73 degrees above average, the second-warmest on record.
Christy said based on the available satellite data, the planet has warmed at the rate of 0.2 degrees per decade, or 2 degrees per century.
