Incoming Democratic leaders of the House Natural Resources Committee, Rep. Raul M. Grijalva of Arizona and Rep. Alan Lowenthal of California, highlight an environmental report by the U.S. Geological Survey that concluded public lands are responsible for nearly a quarter of all U.S. carbon dioxide emissions. Noting the Trump administration's enthusiastic endorsement of coal mining and oil and gas drilling on public lands, they vow to explore better options, especially in light of another report, mandated by Congress, that gave new urgency to expected impacts of climate change on people's health, their homes, and the overall U.S. economy. "Our parks, forests, oceans, and wild, open spaces shouldn't be used to make our climate crisis worse," say the lawmakers, endorsing the transition to sustainable use of the nation's considerable renewable resources.
