Flat (and cool) earth society: In response to recent warnings by the United Nations Intergovernmental Panel on Climate Change (IPCC) about the consequences of greenhouse-gas emissions, the conservative American Enterprise Institute is offering a $10,000 prize to scientists and economists who write articles which call attention to weaknesses of the IPCC report. In reporting this news, the Chronicle of Higher Education (March 2) said it is eagerly awaiting a patron who will offer “a reward for papers that discredit the spherical-earth theories that have been circulating for the past millennium or so.”
