“Witnesses testified on how the greenhouse effect will change the global climate system and possible solutions.”
Carl Sagan testified before Congress in 1985 about the urgent need to address climate change. In this historic footage from 1985, he presents compelling evidence of the devastating impact of human activity on our planet’s climate and calls for immediate action to address this critical issue1.
We are all in this greenhouse together!

What would Carl Sagan do to fight global warming?
Carl Sagan was concerned about climate change and testified before Congress in 1985 about the impact of climate change on Earth. He discussed how burning fossil fuels and using aerosol led to an increase in carbon dioxide in our atmosphere1. He also campaigned for nuclear disarmament and opposed the Strategic Defense Initiative of U.S. Pres. Ronald Reagan2. In 1983 he co-wrote the paper that introduced the concept of “nuclear winter,” a catastrophic global cooling that would result from a nuclear war3.
