On Class M, James Hrynyshyn shows us how climate change will benefit the economies of some U.S. counties while damaging many others. This mostly has to do with location; coastal areas and southern latitudes are more threatened, with Florida poised to suffer worst of all. James writes, “we’re not just talking about polar bears anymore. It’s now about jobs, wages, infrastructure, crime.” Meanwhile, William M. Connolley reports Antarctica’s Larsen C ice shelf is 12% smaller due to a giant iceberg splitting off and heading (presumably) toward Miami. Greg Laden says denial of global warming has shaped political discourse for decades, thanks to “deep pocketed one percenters and corporations harboring the unfortunate delusion that if we pretend climate change is not caused by the burning of fossil fuels, everything will be fine and they’ll keep getting rich.” But public awareness of the problem, like sea level, continues to rise.
