Every month at about this time (or perhaps a bit earlier) the National Climate Data Center (NCDC), itself a part of the National Oceanographic and Atmospheric Administration (NOAA) posts a report called "State of the Climate" with the most recent data on temperature, precipitation and so on.
This month's report is unsettling. Some bullet points:
- The combined global land and ocean average surface temperature for June 2010 was the warmest on record at 16.2°C (61.1°F), which is 0.68°C (1.22°F) above the 20thcentury average of 15.5°C (59.9°F). The previous record for June was set in 2005.
- The June worldwide averaged land surface temperature was 1.07°C (1.93°F) above the 20th century average of 13.3°C (55.9°F)—the warmest on record.
- It was the warmest January–June on record for the global land and ocean temperature. The worldwide land on average had its second warmest January–June, behind 2007. The worldwide averaged ocean temperature was the second warmest January–June, behind 1998.
If it is, then where do these numbers come from?
Must be some conspiracy, indeed.
