Two interesting statistics from the NOAA National Climate Data Center:
June 2010 was the fourth consecutive warmest month on record (March, April, and May 2010 were also the warmest on record). This was the 304th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985.
It was the warmest Januaryâ€“June on record for the global land and ocean temperature. The worldwide land on average had its second warmest Januaryâ€“June, behind 2007. The worldwide averaged ocean temperature was the second warmest Januaryâ€“June, behind 1998.
Yes, those figures are for the whole planet.
