In the third major high-court decision in the last two weeks to deal a blow to public health, a 6–3 U.S. Supreme Court majority restricted the ability of the Environmental Protection Agency to effectively regulate the greenhouse-gas emissions that cause climate change and have been proven to harm the public health.
