About Us

Astronomers for Planet Earth is a volunteer network of astronomers, astronomy students, and astronomy educators committed to bringing our voices to the struggle against climate change and for climate justice. The organization grew out of groups that formed independently in 2019, one in North America and one in Europe.

The nearly 1900 members of Astronomers for Planet Earth (as of June 2023) hail from 74 countries: the United States, United Kingdom, Switzerland, Norway, China, New Zealand, Canada, Hungary, Chile, Germany, Netherlands, France, Denmark, Italy, Brazil, Serbia, Mexico, India, Australia, Ireland, Spain, Czechia, South Africa, Finland, Sweden, Uruguay, Bulgaria, Belgium, Austria, Colombia, Argentina, Nigeria, Portugal, Kenya, Pakistan, Philippines, Azerbaijan, Iran, Dominican Republic, Turkey, Japan, Namibia, Poland, Haiti, Rwanda, Tunisia, Ghana, Mozambique, Greece, Ukraine, Indonesia, Ethiopia, Croatia, Taiwan, Kazakhstan, Madagascar, Cameroon, Paraguay, Sudan, Bangladesh, Nicaragua, Syria, Nepal, Malaysia, Uganda, Trinidad, Estonia, Mauritius, Senegal, Hong Kong, South Korea, Israel, Russia, and Romania.

Adrienne Cool

San Francisco State University

Inspired by the young people in her life, Adrienne founded Astronomers for Planet Earth together with students at SFSU and Debra Fischer at Yale. Like astronomers everywhere, she spends a good deal of time contemplating things that are impossibly far away. She believes that this experience gives astronomers a distinct perspective on our home planet that can and should be harnessed in the struggle to combat climate change.

Debra Fischer

Yale University

Debra is a Professor of Astronomy who has been detecting exoplanets since 1997. She leads the 100 Earths project using the EXPRES spectrograph, built by her team and now operating at the Lowell Discovery Telescope. Planets similar to Earth are hard to find and impractical destinations for humanity. The Earth is our only home. However, the quality of life on Earth is threatened by our use of fossil fuels. Debra wants to do everything possible to mitigate climate change for her children and for all living creatures on Earth. She believes that astronomers can work together to effect equitable solutions.

Our climate statement

Overwhelming scientific evidence demonstrates that human activity — particularly the use of fossil fuels — is warming our planet’s surface and oceans, causing Earth’s climate to change in ways that threaten the future of human civilization world-wide.
