State of the Climate
* The combined global land and ocean average surface temperature for June 2011 was the seventh warmest on record at 16.54°C (60.94°F), which is 0.58°C (1.04°F) above the 20th century average of 15.5°C (59.9°F).
* June 2011 was the 316th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985.
* The June worldwide average land surface temperature was 0.89°C (1.60°F) above the 20th century average of 13.3°C (55.9°F)—the fourth warmest on record.
* The global average ocean surface temperature was the 10th warmest June on record, at 0.47°C (0.85°F) above average. Neither El Niño nor La Niña conditions were present during June 2011. According to NOAA's Climate Prediction Center, these ENSO-neutral conditions are expected to continue into the Northern Hemisphere fall 2011.
* The first half of 2011 (January–June) was the 11th warmest on record for the combined global land and ocean surface temperature. Separately, the worldwide average ocean temperature was also the 11th warmest January–June and the worldwide average land temperature was the 12th warmest such period."
"Direct observations find that CO2 is rising sharply due to human activity. Satellite and surface measurements find less energy is escaping to space at CO2 absorption wavelengths. Ocean and surface temperature measurements find the planet continues to accumulate heat. This gives a line of empirical evidence that human CO2 emissions are causing global warming."
