Call it the mystery of the missing thermometers.
Two months after “climategate” cast doubt on some of the science behind global warming, new questions are being raised about the reliability of a key temperature database, used by the United Nations and climate change scientists as proof of recent planetary warming.
Two American researchers allege that U.S. government scientists have skewed global temperature trends by ignoring readings from thousands of local weather stations around the world, particularly those in colder altitudes and more northerly latitudes, such as Canada.
In the 1970s, nearly 600 Canadian weather stations fed surface temperature readings into a global database assembled by the U.S. National Oceanic and Atmospheric Administration (NOAA). Today, NOAA only collects data from 35 stations across Canada.
Mr. D’Aleo and Mr. Smith say NOAA and another U.S. agency, the NASA Goddard Institute for Space Studies (GISS) have not only reduced the total number of Canadian weather stations in the database, but have “cherry picked” the ones that remain by choosing sites in relatively warmer places, including more southerly locations, or sites closer to airports, cities or the sea -- which has a warming effect on winter weather.
Over the past two decades, they say, “the percentage of [Canadian] stations in the lower elevations tripled and those at higher elevations, above 300 feet, were reduced in half.”
“NOAA . . . systematically eliminated 75% of the world’s stations with a clear bias towards removing higher latitude, high altitude and rural locations, all of which had a tendency to be cooler,” the authors say. “The thermometers in a sense, marched towards the tropics, the sea, and to airport tarmacs.” More here:
Hmmm. Interesting. Do you think this will matter one whit to the likes of AlGore and the rest of the global warming monkeys?

I once mention the words, "nuclear energy" to a liberal and almost got splattered from the spray of explosive diarrhea that blasted from his bowels as fears of Godzilla, China Syndrome and Captain Planet cartoons short
circuited his brain.
