At the opening of the U.N. climate change summit on Tuesday, a hundred world leaders (including our own president) were greeted by a 13-year-old girl from India named Yugratna, whose message was simple: We're just not doing enough to fight global warming:

YUGRATNA SRIVASTAVA, TROUBLED TEEN: The Himalayas are melting. The polar bears are dying. Two of every five people don't have access to clean drinking water.

Is this what we're going to give to our future generations? Please no.

But here's a key rule one must know about left-wing propaganda: Once they trot out the kids, you know you're being fed a pile of crap the size of Al Gore's houseboat.

Using pubescent pawns is based on the successful belief that no one dare question children, because they're smaller than adults and, for the most part, sincere. Also, they're adorable and can make up stories about you if you don't submit to their fickle wishes.

Now, you know if anyone at that meeting were to stand up to Yugratna and say: "Hey kid, shouldn't you be in school instead of trying to ruin our economy based on phony science?" you'd be stoned to death with knives made of stone... shaped like knives.

So, God bless Czech President Vaclav Klaus. The world's gutsiest leader went after the U.N. for this shameless BS, saying: "It was sad and... frustrating. It's a propagandistic exercise where 13-year-old girls from some far-away country perform a pre-rehearsed poem. It's simply not dignified."

See, Klaus is a skeptic on global warming and he's no dope. He realizes, like a growing number of experts in the scientific community, that climate change is more likely nature's doing, not humans. It's too bad, however, that politicians, like our own president, would choose to listen to a teenage girl instead.

Maybe if Klaus wore a jumper and had pigtails things would change.

And if you disagree with me, then you're probably a racist.
