According to a
post on
Universe Today in this new NASA study:
"...scientists analyzed the GISTEMP data to see if past predictions of rising temperatures were accurate. They needed to know that any uncertainty within their data was correctly accounted for. The goal was to make sure that the models they use are robust enough to rely on in the future. The answer: Yes they are. Within 1/20th a degree Celsius."
The above map (NASA) represents global temperature anomalies averaged from 2008 through 2012.
Note that for our part of the world there seems to be a rise of between half and one degree Celsius.
