NOAA reports 2010 hottest year on record so far
Summer 2010 the second warmest on record; hottest August in RSS satellite record*
September 15, 2010
Following fast on the heels of NASA reporting the hottest January to August on record, NOAA’s National Climatic Data Center has released its State of the Climate: Global Analysis for August.
NOAA reports the details (and the graphic):
The first eight months of 2010 tied the same period in 1998 for the warmest combined land and ocean surface temperature on record worldwide. Meanwhile, the June–August summer was the second warmest on record globally after 1998, and last month was the third warmest August on record. Separately, last month’s global average land surface temperature was the second warmest on record for August, while the global ocean surface temperature tied with 1997 as the sixth warmest for August….
For January–August 2010, the global combined land and ocean surface temperature of 58.5 F (14.7 C) tied with 1998 as the warmest January–August period on record. This value is 1.21 F (0.67 C) above the 20th century average.
The combined global land and ocean surface temperature for August 2010 was the third warmest on record at 61.2 F (16.2 C), which is 1.08 F (0.60 C) above the 20th century average of 60.1 F (15.6 C). August 1998 is the warmest August on record and 2009 is the second warmest….
The combined global land and ocean average surface temperature for June–August 2010 was the second warmest on record, behind 1998, at 61.3 F (16.2 C), which is 1.15 F (0.64 C) above the 20th century average of 60.1 F (15.6 C).
The June–August worldwide land surface temperature was 1.80 F (1.00 C) above the 20th century average of 56.9 F (13.8 C) — the warmest June–August on record, surpassing the previous record of 1.66 F (0.92 C) set in 1998.
Still warming….
UPDATE: The RSS satellite data for the month is out and August 2010 just beat up 1998.
And again, the record warmth that we are seeing this year is all the more powerful evidence of human-caused warming “because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect,” as a recent must-read NASA paper notes:
NASA: The 12-month running mean global temperature has reached a new record in 2010 — despite recent minimum of solar irradiance: “We conclude that global temperature continued to rise rapidly in the past decade” and “there has been no reduction in the global warming trend of 0.15-0.20°C/decade that began in the late 1970s.”
