One aspect of climate change that's already affecting people in various parts of the world is the slow but steady rise in sea level (via YaleE360): Pacific and Indian Ocean atoll nations are already being abandoned because of the direct and indirect effects of sea level rise, such as saltwater intrusion into groundwater. In the Marshall Islands, some crops are being grown in abandoned 55-gallon oil drums because the ground is now too salty for planting. New Zealand is accepting, on a gradual basis, all of the inhabitants of the Tuvalu atolls.
George Stephanopoulos turned up at the Supreme Court last week, sitting next to Joel Klein, the deputy White House counsel. Their joint appearance seemed to illustrate the administration's anxiety about the case, Adarand v. Pena, in which the Court is being asked to strike down racial preferences in the construction industry that have been endorsed by every president since Nixon. But Klein assured me afterward that Stephanopoulos, who had never seen a Supreme Court argument before, had come along purely out of curiosity. He picked a good day.
