Three Quick Facts about Climate Science

  1. The “greenhouse effect” describes warming that results when Earth’s atmosphere traps heat radiating from Earth toward space. Scientists believe an expanding greenhouse effect created by higher levels of gases like carbon dioxide (CO2) and methane is causing global temperatures to rise.

  2. The average global temperature has increased nearly 1.5˚F in the last century. About 97% of climate scientists agree that human activity is contributing to this rise.

  3. The Paris Climate Agreement was originally signed on Earth Day 2016. This landmark global accord established goals for countries to address climate change. It sets targets related to limiting a further rise in global temperatures and reducing greenhouse gas emissions. The U.S. announced in January that it would rejoin the agreement.
