Thirty-one of the largest U.S. science societies—collectively representing millions of scientists—sent a letter to Congress this week urging lawmakers to recognize anthropogenic climate change and take decisive action to combat it and its effects. “The letter continues the decades-long efforts of the scientific community to persuade Congress to act on the climate crisis,” says Sarah Green, a chemistry professor at Michigan Technological University who studies climate change and who is affiliated with of several of the societies that signed the letter.
