The United States was the world’s largest source of carbon emissions for more than a century. In a new analysis, researchers document the changing trends in U.S. carbon emissions from the late 19th century to the early 21st century, focusing on emissions from fossil fuels and industry. They discuss the main factors that contributed to the rollercoaster of changes in historical carbon emissions. The authors close by offering lessons from the U.S. experience for developing countries.

The Michigan Womyn’s Music Festival, hosted from 1976 to 2015, brought together lesbian feminists for a celebration of culture and activism. Today, the festival is perhaps best known for its controversial "womyn-born-womyn” attendance policy, which excluded trans women from participation. A new article in Signs: Journal of Women and Culture in Society examines the fight for trans inclusion at Michfest and positions it within a rich history of activism at the festival, including antiracist activism by women of color.
