In 1988, James Hansen, a climatologist, told the US Congress that temperature would rise 0.3C by the end of the century (it rose 0.1C), and that sea level would rise several feet (no, one inch). The UN set up a transnational bureaucracy, the Intergovernmental Panel on Climate Change (IPCC).The UN has even recently published a children's book replete with talking animals in order to scare them that the culprit in so called "climate change" is modern western industrialization while ignoring the sun's cycle of warming and cooling. This is further evidence that politicians with an agenda will not shrink from using the public treasury to subvert science in order to achieve their goals.
So to the scare. First, the UN implies that carbon dioxide ended the last four ice ages. It displays two 450,000-year graphs: a sawtooth curve of temperature and a sawtooth of airborne CO2 that's scaled to look similar. Usually, similar curves are superimposed for comparison. The UN didn't do that. If it had, the truth would have shown: the changes in temperature preceded the changes in CO2 levels.
Next, the UN abolished the medieval warm period (the global warming at the end of the First Millennium AD). In 1995, David Deming, a geoscientist at the University of Oklahoma, had written an article reconstructing 150 years of North American temperatures from borehole data. He later wrote: "With the publication of the article in Science, I gained significant credibility in the community of scientists working on climate change. They thought I was one of them, someone who would pervert science in the service of social and political causes. One of them let his guard down. A major person working in the area of climate change and global warming sent me an astonishing email that said: 'We have to get rid of the Medieval Warm Period.' "
So they did. The UN's second assessment report, in 1996, showed a 1,000-year graph demonstrating that temperature in the Middle Ages was warmer than today. But the 2001 report contained a new graph showing no medieval warm period. It wrongly concluded that the 20th century was the warmest for 1,000 years.
Scores of scientific papers show that the medieval warm period was real, global and up to 3C warmer than now. Then, there were no glaciers in the tropical Andes: today they're there. There were Viking farms in Greenland: now they're under permafrost. There was little ice at the North Pole: a Chinese naval squadron sailed right round the Arctic in 1421 and found none.

A Self-Correcting Problem
"Global warming" strikes again, Reuters reports from Toronto:ht/ James Taranto
Aboriginal communities in Ontario's far north are becoming increasingly isolated as rising temperatures melt their winter route to the outside world and impede their access to supplies. . . .
During the coldest months between January and March, "winter roads" are cleared on the frozen network of rivers and lakes to let trucks deliver bulk supplies like fuel and building materials. . . .
About 20,000 people live in the remote reservations and rely on winter shipments of heating oil, gasoline, and diesel fuel to power generating stations.
Of course, if they can't get fuel, they can't burn it--which means they will no longer contribute to "global warming"! Isn't it nice how that works out?
