NOAA GHCN has Global Temperatures for October 2nd Warmest (Don’t Believe It)



The Earth’s temperature for the month of October was the second-warmest since records began in 1880, according to data from the National Oceanic and Atmospheric Administration. The month’s average temperature of 58.2 degrees was 1.1 degrees above the 20th century average of 57.1 degrees, trailing only October 2003. For the Earth’s land areas, it was the warmest October on record.

And this NOAA data does include the correct October temperature data for Russia…unlike NASA’s October data released last week, which caused the agency to end up with egg on its face. After NASA announced that October was the warmest ever recorded, eagle-eyed bloggers at skeptic blogs Climate Audit and Watts up with that pointed out that the data from Russia was for September, not October. Of course, this skewed the global temperature higher than it would have been.

Even if you don’t agree with all (or any) of the points or claims posited by the warming skeptics, I think they are doing a needed service by keeping the climate change adherents, such as authors of the RealClimate blog, on their toes. RealClimate’s Gavin Schmidt addressed this in this post: “the extra attention has led to improvements in many products. Nothing of any consequence has changed in terms of our understanding of climate change, but a few more i’s have been dotted and t’s crossed.”

Indeed, as noted above, even with the correct October data from Russia, temperatures across Australia, Asia (including Russia), the western USA, eastern Europe, northern Canada, eastern Brazil, and the southern countries of South America were all warmer-than-average in October. And so far this year, 2008 is the ninth-warmest year on record for the planet, with all nine of the Earth’s warmest years occurring since the mid-1990s. See post here.

This is not surprising as NOAA has become the biggest outlier in recent months. They have thanks to Tom Peterson and Tom Karl a global data base that is worth nothing. There is little or no adjustment for urbanization, land use changes, no adjustment for bad station siting (69% of the 560 US climate stations surveyed by Anthony Watts team of volunteers were poor or very poorly sited), 2/3rds of the stations globally dropped out around 1990, the number of missing months increased tenfold in the FSU and Africa after 1990, and changes in instrumentation like here in the US that Tom Karl himself found produced a warm bias of 0.5F. All these introduce a warm bias, none of which are corrected for. Not less than 6 peer review studies (bold in references) have shown these issues may account for up to 50% of the warming since 1900. Trust only the satellite. In fact, this October was the 10th warmest of the 30 years of data for the MSU satellite according to UAH with only a 0.167C (0.3F) anomaly instead of the 1.1F (2nd warmest out of 129 years) as per NOAA. Unfortunately satellite data extends only back to 1979.
