NASA argues with itself


Press release today from Goddard Institute for Space Studies says:

The temperature analysis produced at GISS is compiled from weather data from more than 1,000 meteorological stations around the world, satellite observations of sea-surface temperature, and Antarctic research station measurements, taking into account station history and urban heat island effects. Software is used to calculate the difference between surface temperature in a given month and the average temperature for the same place from 1951 to 1980. This three-decade period functions as a baseline for the analysis. It has been 38 years since the recording of a year of cooler than average temperatures.

(emphasis mine)

He’s not mentioned in the press release, but GISS is the home of Dr. James Hansen, the guy who earned a quarter of a million bucks or more in just one year for speaking about “climate change”.

Here’s the GISS temperature anomaly chart for 2013.
2013 anomaly

Wow, lots of red, very little blue. Hmmm. My opinion is that GISS distorts and uses fudge factors to keep the alarm going, even as everything in DC gets shut down for snow. Now here is some data I can believe in:

Well, that looks a little different, doesn’t it? If you go to Dr. Spencer’s website, he has actual numbers. I bet you could file FOIA requests on GISS for a year and never get the raw data, much less what their “software” is doing to it. Dr. Spencer also says things like:

What is astounding from a science perspective is that [Science Czar John] Holdren blamed warming on waste heat, the result of humans and their energy use, rather than a slowly increasing greenhouse effect… Assuming today’s global energy use is about 150 petawatthours per year, and dividing that by the number of hours in a year and the surface area of the Earth, this yields an average energy flux of 0.03 Watt per sq. meter. This is about 100 times smaller than the estimated heating from increased carbon dioxide in the atmosphere. It is almost 10,000 times smaller than the rate of solar energy input into the Earth.

(Spencer also says things like, “You have to laugh at least once a day. Because a day without sunshine is like…night.” Gotta love a scientist with a sense of humor.)

Going back to the first article, GISS says that 2013 was the hottest year on record for Australia. Joanne Nova looks at the discreptancy between what the ground stations and the satellites say. That group of researchers looked at the weather station data and tried to come up with the same answer as the Bureau of Meteorology (BOM). The only way they could do it was to use the hottest 339 weather stations in Australia and ignore the other 382.

For most Australians on Jan 7th the heatwave averaged somewhere around 35C, not 40.3C.
To have any legitimacy with a new record, the BOM needs to publish its methods that explain how temperatures can be calculated every day over a hundred years from weather stations that in many cases didn’t exist. How else would we know it was a reasonable effort? We all know that tweaked black-box statistics could be used to achieve meaningless records that drive news headlines. Of course, the BOM wouldn’t stoop that low, would they?

I wouldn’t hold my breath for that.

    Maintained a computerized weather station in the middle of an airfield relatively away from the middle of the runway and all else. Just before I retired, the U.S. government started installing a new computerized weather station for their recording information on the weather. Of course the new site was at the take-off end of the main runway, taxi-way turn and heavy traffic 6-lane highway.

    • There has been a lot of similar trash. Many of the older stations were originally erected when the site was rural, but urban and suburban areas have grown up around them. When I lived in the Nashville area, my home out in the sticks was about 5-10 degrees cooler during the summer. A lot of trees and a lot less pavement and brick make a big difference. The older stations were never renormed to provide a better indication of the real temps.
