Come off it. That is a partial and tendencious view of that research at best. See the article in New Scientist a couple of weeks ago. See the latest edition of Nature.

Apart from them there is a virtual unanimity view emerging. Could they all be wrong? Of course, it's the scientific method. But it is a methodical view; it's also mankind's best and most educated guess right now. If you want to jump off the cliff with the SUV brigade, go ahead... people will still be calling our gleefully "look, there's no problem..." even just before they hit the beach.
