Global warming can seem too 3 to worry about, or too uncertain-something projected by the same computer 4 that often can't get next week's weather right. On a raw winter day you might think that a few degrees of warming wouldn't be such a bad thing anyway. And no doubt about it: Warnings about 5 change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles.
