The fact is that the planet is changing faster than even pessimists expected: ice caps are shrinking, arid zones spreading, at a terrifying rate. And according to a number of recent studies, catastrophe - a rise in temperature so large as to be almost unthinkable - can no longer be considered a mere possibility. It is, instead, the most likely outcome if we continue along our present course.

Thus researchers at M.I.T., who were previously predicting a temperature rise of a little more than 4 degrees by the end of this century, are now predicting a rise of more than 9 degrees. Why? Global greenhouse gas emissions are rising faster than expected; some mitigating factors, like absorption of carbon dioxide by the oceans, are turning out to be weaker than hoped; and there's growing evidence that climate change is self-reinforcing - that, for example, rising temperatures will cause some arctic tundra to defrost, releasing even more carbon dioxide into the atmosphere.

As a recent authoritative U.S. government report points out, by the end of this century New Hampshire may well have the climate of North Carolina today, Illinois may have the climate of East Texas, and across the country extreme, deadly heat waves - the kind that traditionally occur only once in a generation - may become annual or biannual events.

In other words, we're facing a clear and present danger to our way of life, perhaps even to civilization itself. How can anyone justify failing to act?

if you watched the debate on Friday, you didn't see people who've thought hard about a crucial issue, and are trying to do the right thing. What you saw, instead, were people who show no sign of being interested in the truth. They don't like the political and policy implications of climate change, so they've decided not to believe in it - and they'll grab any argument, no matter how disreputable, that feeds their denial.

Indeed, if there was a defining moment in Friday's debate, it was the declaration by Representative Paul Broun of Georgia that climate change is nothing but a "hoax" that has been "perpetrated out of the scientific community." I'd call this a crazy conspiracy theory, but doing so would actually be unfair to crazy conspiracy theorists. After all, to believe that global warming is a hoax you have to believe in a vast cabal consisting of thousands of scientists - a cabal so powerful that it has managed to create false records on everything from global temperatures to Arctic sea ice.

Yet Mr. Broun's declaration was met with applause.

Do you remember the days when Bush administration officials claimed that terrorism posed an "existential threat" to America, a threat in whose face normal rules no longer applied? That was hyperbole - but the existential threat from climate change is all too real.

Yet the deniers are choosing, willfully, to ignore that threat, placing future generations of Americans in grave danger, simply because it's in their political interest to pretend that there's nothing to worry about. If that's not betrayal, I don't know what is.
