Last year at the same time, I told you that 2005 was the warmest year ever recorded .
The results for 2006 have just arrived: it ranks fifth, and therefore take the 2004 which took place earlier this rank behind, in order, 2005, 1998, 2002 and 2003.
And here is what gives the temperature curve which is at the bedside of our planet, with the average temperature reading for 2006:
This is an average temperature . But this average conceals very different situations depending on where you are on Earth. The distribution of surface temperature anomaly for 2006:
This diagram shows the temperature deviation in 2006 compared to averages temperatures observed from 1951 to 1980, as a reference. The deviation in ° C is given by the color code at the bottom of the scale of the image.
As you can see from this diagram, the warming is much more pronounced in the Arctic where it is around 3 ° C. At the same time, there are places where there is a very low warming or cooling, as in some ocean areas colored blue.
James Hansen, director of NASA GISS, said: "2007 should be warmer than 2006 because of the return of El Niño in the Pacific Ocean and Because of the continuous increase of the emission of greenhouse gas emissions by mankind. "
