　　Passage 6

　　Theres no question that the Earth is getting hotter. The real questions are: How much of the warming is our fault, and are we 47 to slow the devastation by controlling our insatiable 48 for fossil fuels?

　　Global warming can seem too 49 to worry about, or too uncertainsomething projected by the same computer 50 that often cant get next weeks weather right. On a raw winter day you might think that a few degrees of warming wouldnt be such a bad thing anyway. And no doubt about it: Warnings about 51 change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles.

　　Comforting thoughts, perhaps. Unfortunately, however, the Earth has some discomforting news.

　　From Alaska to the snowy peaks of the Andes the world is heating up right now, and fast. Globally, the 52 is up 1F over the past century, but some of the coldest, most remote spots have warmed much more. The results arent pretty. Ice is 53, rivers are running dry, and coasts are 54, threatening communities.

　　The 55 are happening largely out of sight. But they shouldnt be out of mind, because they are omens of whats in store for the 56 of the planet.
