The best reporting of...climate change has come from Elizabeth Kolbert in the New Yorker. Her three-part series last spring lucidly explained the harbingers of potential disaster: a shrinking of Arctic sea ice by 250 million acres since 1979; a thawing of the permafrost for what appears to be the first time in 120,000 years; a steady warming of Earth's surface temperature; changes in rainfall patterns that could presage severe droughts of the sort that destroyed ancient civilizations. This month she published a new piece, Butterfly Lessons," that looked at how these delicate creatures are moving into new habitats as the planet warms. Her real point was that all life, from microorganisms to human beings, will have to adapt, and in ways that could be dangerous and destabilizing. If people such as...Kolbert are right, we are all but ignoring the biggest story in the history of humankind. Kolbert concluded her series last year with this shattering thought: "It may seem impossible to imagine that a technologically advanced society could choose, in essence, to destroy itself, but that is what we are now in the process of doing." The failure of the United States to get serious about climate change is unforgivable, a human folly beyond imagining.
