Someone at GISS appears to have a sense of humour. The graph above shows annual average temperatures (not anomalies) for the capital of Greenland. It looks like 2010 is by far the warmest year on record.
Most people displaying this type of information would be sensible enough to wait until the end of the year to calculate an annual mean. Obviously the January-August mean temperature is going to be much higher than the January-December mean. The 2010 data point should not appear on the graph until 2010 is over.
