ScienceDaily (Dec. 13, 2007) — The decade of 1998-2007 is the warmest on record, according to data sources obtained by the World Meteorological Organization (WMO). The global mean surface temperature for 2007 is currently estimated at 0.41°C/0.74°F above the 1961-1990 annual average of 14.00°C/57.20°F...
...Since the start of the 20th century, the global average surface temperature has risen by 0.74°C. But this rise has not been continuous. The linear warming trend over the last 50 years (0.13°C per decade) is nearly twice that for the last 100 years...
...2007 global temperatures have been averaged separately for both hemispheres. Surface temperatures for the northern hemisphere are likely to be the second warmest on record, at 0.63°C above the 30-year mean (1961-90) of 14.6°C/58.3°F. The southern hemisphere temperature is 0.20°C higher than the 30-year average of 13.4°C/56.1°F, making it the ninth warmest in the instrumental record since 1850.
January 2007 was the warmest January in the global average temperature record at 12.7°C/54.9°F, compared to the 1961-1990 January long-term average of 12.1°C/53.8°F...

There%26#039;s a lot less controversy about this is the real world than there is on Yahoo answers:

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:
http://en.wikipedia.org/wiki/Scientific_...
http://www.sciencemag.org/cgi/content/fu...
EVERY major scientific organization has issued an official statement that this is real, and mostly caused by us. The National Academy of Sciences, the American Association for the Advancement of Science, the American Institute of Physics, the American Chemical Society, the American Geophysical Union, the American Meteorological Association, etc.
