Environment: The United Nations makes a claim that can't be supported by science, and U.S. researchers ignore temperature data from frigid regions. The crack-up of the global warming fraud is picking up speed.

With so much of the science behind climate change coming under attack, especially among scientists, it's been a harsh winter for the global warming crowd:

• In late November, thousands of e-mails from the Climate Research Unit of the University of East Anglia were leaked to the public. The evidence strongly suggests that researchers colluded to prove the global warming scientific "consensus" by rigging, burying and destroying data that ran counter to their political agenda.

• Last week, the public learned that claims made by the U.N.'s International Panel on Climate Change were not based on science, but on speculation. Specifically, the IPCC's 2007 report said the Himalayan glaciers will be gone by 2035 due to man-made global warming.

The claim, used at the U.N. Copenhagen climate change conference in cold and snowy December to rush through a restrictive greenhouse-gas-emissions treaty, was not based on a scientific study. It was based on a telephone call that a reporter had with a scientist who was speculating.

The IPCC has withdrawn the claim. Murari Lal, the scientist who included the contention in the U.N. report, admitted that he knew it wasn't based on peer-reviewed scientific research.

• Also in the last week, it was revealed that U.S. researchers working for the National Oceanic and Atmospheric Administration are excluding temperature data from cold regions for a database used by the U.N. in its global warming scare campaign.

Canwest News Service, a Canadian agency that also owns a chain of newspapers, reported Friday, "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. Today, NOAA only collects data from 35 stations across Canada.

"Worse, only one station — at Eureka on Ellesmere Island — is now used by NOAA as a temperature gauge for all Canadian territory above the Arctic Circle.

"The Canadian government, meanwhile, operates 1,400 surface weather stations across the country, and more than 100 above the Arctic Circle, according to Environment Canada."

Canwest also reports that Americans Joseph D'Aleo, a meteorologist, and E. Michael Smith, a computer programmer, say that the NASA Goddard Institute for Space Studies has "reduced the total number of Canadian weather stations in the database" and has "cherry-picked" the stations.
