Global Cooling Continues

By James M. Taylor, Heartland Institute

Continuing a decade-long trend of declining global temperatures, the year 2008 was significantly colder than 2007, and global temperatures for the year were below the average over the past 30 years. The global temperature data, reported by NASA satellite-based temperature measurements, refuted predictions 2008 would be one of the warmest on record.

Data show 2008 ranked 14th coldest of the 30 years measured by NASA satellite instruments since they were first launched in 1979. It was the coldest year since 2000.

Satellite Precision

NASA satellites uniformly monitor the Earth�s lower atmosphere, which greenhouse gas theory predicts will show the first and most significant effects of human-caused global warming. The satellite-based measurements are uncorrupted by urban heat islands and localized land-use changes that often taint records from surface temperature stations, giving false indications of warming.

The uncorrupted satellite-based temperature measurements refute surface temperature station data finding 2008 to be one of the top 10 warmest years on record. “How can an ‘average year’ in one database appear to be a [top 10] warmest year in another?” asked meteorologist Joe D’Aleo on his International Climate and Environmental Change Assessment Project Web site.

“The global databases of [surface station reports] are all contaminated by urbanization, major station dropout, missing data, bad siting, instruments with known warm biases being introduced without adjustment, and black-box and man-made adjustments designed to maximize [reported] warming,” explained D’Aleo.

Warming Trend Overstated

“The substantial and continuing La Nina cooled the Earth quite a bit in 2008, to the point that it was slightly below the 30-year average [1979-2008] but slightly above the 20-year average [1979-1998],” said John Christy, distinguished professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville (UAH).

“From research we have published, and more to come soon, we find that land surface air temperatures misrepresent the actual temperature changes in the deep atmosphere – where the greenhouse effect is anticipated to have its easiest impact to measure. Surface thermometers are affected by many influences, especially surface development, so the bulk atmospheric measurements from satellites offer a straightforward indicator of how much heat is or is not accumulating in the air, for whatever reason,” Christy explained.

“Recent published evidence also supports the long-term trends of UAH as being fairly precise, so the observed rate of warming is noticeably less than that projected by the IPCC ‘Best Estimate’ model simulations which, we hypothesize, are too sensitive to CO2 increases,” Christy added.

“The global temperature data, reported by NASA satellite-based temperature measurements, refuted predictions 2008 would be one of the warmest on record.”

false.

Here’s the direct quote from the Met Office, from a press release dated 3rd of January 2008:

“2008 is set to be cooler globally than recent years say Met Office and University of East Anglia climate scientists, but is still forecast to be one of the top-ten warmest years.”

As predicted it was cooler than 2007, but still the tenth warmest year on record.

Only the 10th warmest? Hmm, where did all the global warming go?

3. Jeremy - February 18, 2009

10th warmest not good enough for you?

4. honestclimate - February 18, 2009

Co2 is at record high levels and the globe is cooling. What’s been driving the climate?
Hint: Look at that orange ball in the sky…

… and in 2009 the Arctic ice extent is back to normal.

… as the Antarctic continues its 30 year cooling trend.

#5 How wrong can you get? Arctic ice extent is not back to normal. (See http://nsidc.org/data/seaice_index/images/daily_images/N_timeseries.png and http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm). The extent of Arctic sea ice remains well below the 1979 to 2000 average even with 2 sucessive years with El Nina conditions. Perhaps you were confused by the distorted version of the data from the University of Illinois on total global sea ice that found its way into (SNIP, don’t use that term here) blogs and George Will’s column?

The Antarctic is not cooling which, in itself, would not conflict with AGO modelling. It is warming! (See http://faculty.washington.edu/steig/nature09data/ and (SNIP, do not link to websites which engage in ad homs).

Do your part if you believe it, stop breathing. But leave the rest of us alone to live a normal life, which is not coming to an end. Get over it already you freaks. Thanks
