This week President Trump announced that the EPA would reverse and eliminate an Obama Administration greenhouse gas rule that has been unfairly used to justify broad and sweeping “climate change” regulations. Specifically, the EPA will remove the 2009 “endangerment finding,” which identifies six greenhouse gases— which provide vital food for plants in greenhouses— as “a threat to public health and welfare.” And, because this standard was so broadly used, its roll back is being considered the largest act of environmental deregulation in American history.
