It’s a shame, really. We’ve been aware of the climate change
effect of carbon dioxide for over 100 years. We’ve known for at
least 30 years that human-caused increases in CO2 and other
greenhouse gases will have a powerful impact on climate within
decades. We’ve seen it happen — already. We now know that its
effect over the next century will be disastrous. But we haven’t
moved an inch toward stopping what will bring disaster on our
own heads. It’s like knowing all about the tremendous harm from
smoking cigarettes, but still inhaling three packs a day. This
is genuine knowledge, not just some flimsy theory and not

enough to make you dizzy. But the reality of global warming, the
human cause, and the extreme danger are not among the
uncertainties. And I do mean knowledge, all that talk about how
it’s not a problem is just people and politicians blowing smoke
