While some blame sodomites, and others blame Israel's land for peace program, Jeremy Rifkin is blaming Katrina and Rita on just plain old Americans:

Make no mistake about it. We Americans created these monster storms. We've known about the potentially devastating impact of global warming for nearly a generation. Yet we turned up the throttle, as if to say: "We just don't give a damn." What did anyone expect? SUVs make up 52% of all the vehicles owned in America, each a death engine, spewing record amounts of CO2 into the earth's atmosphere.

52% of all the vehicles on the road? Then why does the U.S. Census report 24.2 Million SUVs on the nation's roads? If that's even half of total vehicles, there'd be only around 50 million vehicles in the U.S. For 300 million people? Doesn't sound right. For starters, this environmentalist site claims there are 200 million vehicles here....)

But why quibble over numbers?

The point is that Rifkin presents a compelling argument for the existence of SUVs on Mars.

As hellstorm "Rita" churned in the Gulf, Streisand sat down for a promotional interview with ABCNEWS's Diane Sawyer.

"We are in a global warming emergency state, and these storms are going to become more frequent, more intense," Streisand urgently declares.

But Sawyer did not remind Streisand that a Category 5 hurricane struck the Bahamas with 160 mph winds -- when the singer was five years old, in 1947!
