...only not in the way you have been taught to believe.
Now that Barack Obama is actually going to do something about "global warming" - in the form of a $650 billion cap-and-trade tax that will be paid for by every American - the battle is joined to save our economy and families from utter and complete destitution at the hands of the far-left.
Indiana Governor Mitch Daniels is onto the scam:
This bill would impose enormous taxes and restrictions on free commerce by wealthy but faltering powers — California, Massachusetts and New York — seeking to exploit politically weaker colonies in order to prop up their own decaying economies. Because proceeds from their new taxes, levied mostly on us, will be spent on their social programs while negatively impacting our economy, we Hoosiers decline to submit meekly.
And for what? No honest estimate pretends to suggest that a U.S. cap-and-trade regime will move the world’s thermometer by so much as a tenth of a degree a half century from now. My fellow citizens are being ordered to accept impoverishment for a policy that won’t save a single polar bear.
We are told that although China, India and others show no signs of joining in this dismal process, we will eventually induce their participation by “setting an example.” Watching the ...flow of jobs from our shores to theirs, our friends in Asia and the Third World are far more likely to choose any other path but ours.
Read Paul Krugman here make the exact opposite argument, and you tell me which is more convincing... "once America acts, we can expect much of the world to follow our lead.". OK, Pauli, whatever you say...
Maybe he should read his own paper? Even the New York Times confesses that certain fears are overwrought, to say the least:
A new analysis halves longstanding projections of how much sea levels could rise if Antarctica’s massive western ice sheets fully disintegrated as a result of global warming.
The flow of ice into the sea would probably raise sea levels about 10 feet rather than 20 feet, according to the analysis, published in the May 15 issue of the journal Science.
The Competitve Enterprise Institute, along with the National Taxpayers Union have released the following video to make their point:
How about some...truth:
Fiction: Global warming is a threat that is rapidly getting worse each year.
Fact: There has been no global warming over the last decade. In fact, global average temperature was lower in 2008 than in 1998! 
Fiction: We can cheaply reduce carbon dioxide emissions.
Fact: As President Obama said in the campaign, “Under my plan of a cap and trade system, electricity rates would necessarily skyrocket.” 
Fiction: Cap-and-trade will help the economy by creating lots of new green jobs.
Fact: A recent economic analysis estimates that 2 million jobs would be lost if Congress enacted President Barack Obama’s cap-and-trade bill! 
This is a scam, meant to control people, redistribute their earnings, and throw us back a century in progress. People who are cold, poor, and living in the dark are much easier to rule, after all. And don't be afraid to say so...Ayn wasn't:
"I think it's funny. There was a time when men were afraid that somebody would reveal some secret of theirs that was unknown to their fellows. Nowadays, they're afraid that somebody will name what everybody knows. Have you practical people ever thought that that's all it would take to blast your whole, big, complex structure, with all your laws and guns --- just somebody naming the exact nature of what you're doing? "
Ayn Rand (1905 - 1982)
