The coldest winter in a decade in many places, with snow in unlikely cities such as New Orleans, has deflated some of the hot air in global warming. And a heavy snowfall that paralyzed Washington, D.C., upstaged a mass demonstration scheduled to promote global warming.

Nevertheless, according to Al Gore and the mainstream media, "the debate is over" proving that global warming exists, that humans are causing it and that "science is settled."

But 680 of the world's leading scientists, economists and policy analysts, who met March 8-10 in New York City for the second Heartland International Conference, beg to differ. The title of the conference expressed their doubts: "Global Warming: Was It Ever Really a Crisis?"

These authorities assert that scientists worldwide do not agree that global warming is human induced (in scientific lingo, anthropogenic). They do not even agree that the Earth is still warming.

Many scientists and other observers have come to realize that global warming is no longer a question of science but is all about politics and money. Their slogan, cap-and-trade, was best explained by House Minority Leader John A. Boehner, R-Ohio, as "a carbon tax that will increase taxes on all Americans who drive a car, who have a job, who turn on a light switch."

President Obama is being pressured by James McCarthy, head of the American Association for the Advancement of Science, to rush his carbon tax through Congress before the American people discover the lie in Obama's promise that "95 percent of working families" will not see their taxes rise by "a single dime." In fact, his own budget shows that taxes will rise for 100 percent of Americans for the sake of global warming.

The United Nations Intergovernmental Panel on Climate Change plans to use a treaty to reduce America's use of energy and therefore our standard of living, while forcing us to subsidize energy production in other countries and close our eyes to the omission of China and India from any obligation.
