Science writer Phil Plait's worst nightmare came true. The Republicans won control of the U.S. Senate. What can we expect to happen? In Plait's words, the Republicans will "put a cohort of science-deniers [sic] into positions of authority," which "quite literally affects the future of humanity." Why? Because, now, the United States will no longer be able to address climate change, "the single greatest threat we as a species face today."
