Global Warming and Dire Warnings From the Pentagon
Discussions of global warming's probable impacts tend to have a good news/bad news tenor, and often a tone of plucky optimism -- sure, we may be growing cotton instead of corn in Minnesota someday, but we can adapt to that.
Part of this complacency derives from large uncertainties about what those impacts will be, and how gradually they may be felt. Though the warming trend is clear, and the role of human contributions well understood, forecasting the effects remains an exercise in conjecture.
Unfortunate attitudes contribute as well: our impatience with questions that can't be answered clearly and quickly, our indifference to faraway suffering. So does our confidence that we can avoid, manipulate or accommodate all downsides of environmental mismanagement.
