Climate change critic

In her recent letter to the editor, Catherine Haug cites NASA in her global warming alarmist diatribe (see “Four big hitters,” April 15, 2010). NASA is led by a corrupt alarmist named James Hansen. John Goetz of Climate Audit analyzed the way NASA’s Goddard Institute of Space Studies calculates global temperatures, and found that NASA has changed published figures hundreds of times, resulting in an artificial increase in warming. The single largest increase was 0.27 degrees, which occurred when the temperature anomaly for August 2006 was raised from 0.43 degrees to 0.70—an increase of 63 percent. This is more than one-third of the total increase in global surface temperature that has occurred over the last century, according to the Intergovernmental Panel on Climate Change, and it reveals a large global warming bias.

The United Kingdom’s Hadley Center for Climate Studies found that global temperatures have decreased since 1998, and that the Earth is not much warmer now than in 1878 or 1941. Data from the University of Alabama-Huntsville and Remote Sensing Systems, which both use highly accurate and comprehensive satellite data for measuring global temperatures, agree with Hadley. They found global temperature declining over the past decade or so, with only a slight increase above the 30-year average from 1978 to 2008.

Haug cites climate change in Montana as purported proof of human-caused warming, which isn’t scientific, since warming and cooling has been occurring for millions of years prior to the latest warming period. And she got it wrong: she claims 50 years of warming, but the Earth cooled from about 1945–1975, leading to forecasts of an impending ice age.
