              FILE - Steam billows from a coal-fired power plant Nov. 18, 2021, in Craig, Colo. The Supreme Court on Thursday, June 30, 2022, limited how the nation’s main anti-air pollution law can be used to reduce carbon dioxide emissions from power plants. By a 6-3 vote, with conservatives in the majority, the court said that the Clean Air Act does not give the Environmental Protection Agency broad authority to regulate greenhouse gas emissions from power plants that contribute to global warming.

I don't have voting rights living in DC so what is there left to do but hold signs and protest." She is concerned about climate change, women's rights, and gay rights. (AP Photo/Jacquelyn Martin)
