She missed the "reasoned hypothesis" step. We know that burning fossil fuels produces carbon dioxide, and we know that carbon dioxide is a greenhouse gas. So of course burning fossil fuels will cause warming! And because we've observed the warming, we've confirmed this prediction beyond all reasonable doubt.

When Arrhenius predicted global warming over 100 years ago, he was not looking at past data. He began with a reasoned hypothesis (burning fossil fuels emits carbon dioxide, carbon dioxide is a greenhouse gas, therefore burning fossil fuels will cause warming), made his prediction, and we've observed the warming which proves the prediction correct. It's a slam dunk as far as I'm concerned.

Whether global warming is happening and what the effects will be is a scientific issue. But what we need to do to reduce carbon dioxide emissions is to change energy policies, so that is a political issue. It's just the same as with CFCs eating away the ozone layer and sufur emissions causing acid rain. If no political action had been taken, those would still be problems.

Ironically, most of the people who argue against the science of global warming are opposed to what to do about it. They argue we should not destroy the economy and go back to an agrarian lifestyle. But using LED light bulbs (and doing other things to use energy more efficiently) and generating power from solar, wind, and nuclear are the actual proposed solutions, not lifestyle changes. In effect they're taking a politcal issue and trying to argue it in the scientific arena, which will never work.

Where's the alarmism in calmly stating a true fact? I think many people who react this way add a silent "...and we're all gonna die!" that is neither stated nor implied. I suppose you see what you're looking for everywhere, if you're looking hard enough.

I can assure you it was not pleasant to live through the extinction events that caused major evolutionary changes. When the dinosaurs died off, mammals also had it very rough. That's why we're trying to avoid a large, rapid rise in temperature -- it's going to be unpleasant to live through. It reminds me of the ancient Chinese curse May you live in interesting times.
