NOAA: Second warmest October on record
Wednesday, November 19th, 2008NOAA’s National Climatic Data Center reports:
Based on preliminary data, the globally averaged combined land and sea surface temperature was the second warmest on record for October and ninth warmest on record for the January-October year-to-date period.
Given that this report is just out, I’m assuming they have sorted out the data entry issues that briefly caused problems for NASA (see here and here). Also worth noting from the NCDC report:
- According to the National Snow and Ice Data Center, the October 2008 Northern Hemisphere sea ice extent, which is measured from passive microwave instruments onboard NOAA satellites, was the third least October sea ice extent on record, behind 2007 and 2006. Average ice extent during October 2008 was 8.4 million square kilometers, which is 9.5 percent below the 1979-2000 average. Sea ice extent for October has decreased at a rate of 5.4 percent per decade, since satellite records began in 1979.
- El NiƱo-Southern Oscillation (ENSO) conditions remained in a neutral phase during October.
Since interest in the monthly temperature reports is so keen these days, let me repeat the key points from my an earlier post on the monthly data. While the monthly data doesn’t tell us much about the climate, the peer-reviewed scientific literature has a couple of interesting forecasts for the next decade:
