Today, MSN launches Live Earth, a user-friendly, green-tinged site wrapped around one of the most ambitious music events of all time.

Buckle up!
Floss!
Demand free-range chicken!
Stop Global Warming. NOW!

Is there no end to the constant harping?

Self-appointed hall monitors are haranguing citizens of the world to turn down the Earth's thermostat or risk shriveling the planet like a cheap piece of bacon left too long on the skillet. Pffttttt.

Predictably, reaction to this dreary outcome basically is divided into two camps: the "Yeah, right, sez who?" crowd and their counterpart, the "Yikeees, the world's ending!" camp.

MSN's mission is not to lecture or browbeat you into changing your lifestyle. There's too much of that already, and, frankly, it doesn't work. Our mission is to provide sound information to allow you to make informed choices.

Then there's a third, smaller group. I call it Camp Warren.

Warren Buffett, a man I admire almost as much for his steady diet of DQ burgers, Cokes and Dilly bars as I do for his $50 billion bankroll, had a blinding insight awhile back. As only Buffett can, he framed the issue succinctly and eloquently and cut to the heart of the climate-change issue. If I had the time I'd go back and dig up the exact quote, but I don't, so I'll paraphrase. It boiled down to this:

What if the global warming predictions are accurate; wouldn't it be prudent, and less costly, to act now to reduce carbon emissions while time is still on our side?

Hmmmmmmmm.

Buffett's observation was aimed at governments and large industrial emitters of carbon dioxide -- the gas that is released into the atmosphere when fossil fuels are burned and acts like a heat-trapping blanket -- but it's just as applicable to the individual.

No fool, environmental alarmist or woolly headed liberal, Buffett lives in Nebraska, and has been spotted in Lincoln driving a Lincoln. His investments include utility plants, energy companies and a fleet of private jets -- all big carbon producers. It's not in his financial interest to champion costly regulation, unless of course he believes the risks of doing nothing outweigh the cost of increased intervention. Which brings us to his genius, understanding and managing risk.
