In more climate-related news, Houston Mayor Sylvester Turner has tapped the former head of U.S. operations for oil giant Shell to lead Houston’s post-Hurricane Harvey recovery effort. Marvin Odum was the chair of Shell for eight years. He retired in 2016. Hurricane Harvey killed at least 82 people, flooded thousands of homes and destroyed billions of dollars of property. It also caused widespread environmental contamination, triggering a half-million-gallon gasoline spill and the release of up to 5 million pounds of pollutants into the air.
