Global warming — in pictures

This multi-media piece from CNN.com has text, narration, and a slide show. Gary Braasch took many of the photographs, and Bill McKibben wrote the essay. Together they dramatize the scope and the urgency of the peril facing the globe. The ability of man to respond quickly enough and effectively enough is open to question, but the authors take heart in noting that now there are pictures to document the threats and make them real to people. Now we can imagine a different world, a better world.
