A Warming World

The Economist has a very clear and compelling chart up today showing how the world is warming.  This chart is taken from NOAA's just released report on "The State of the Climate, 2009".  The report was released yesterday, and it says that global warming is "undeniable" and that the 1990's were the warmest on record.  The chart below shows that unambiguously.
