NOAA calculated that 2013 was the 4th warmest year on record globally, and NASA using a slightly different method ranked it 7th. In both cases, the ten warmest years on record have all been since 1998.
With the bitter cold in the Eastern U.S. today, this is a perfect time to illustrate the difference between climate and weather. Climate change doesn’t mean it never gets cold and snowy. It does mean that it happens less often, and is not as severe. When you look at longer periods (that average out the natural cycles of weather and climate) the rise in temperature from the increasing greenhouse gases is very apparent.
NASA has some graphics showing where the warming was most noticeable.
