Over a dozen climate scientists and advocates were arrested last week as they blocked several U.S. airports, protesting the destructive toll private jets have on the environment. Climate protesters targeted private airports in New Jersey, North Carolina, California and Washington state as part of a coordinated global action that also saw demonstrations at at least 13 other private airports in 12 other countries. Among the protesters arrested was Peter Kalmus, a climate scientist at NASA’s Jet Propulsion Lab.

Peter Kalmus: “I feel so awful doing this. It just — I feel sick at heart, and it just feels, like, incredibly messy. I feel gaslit by society. But I know this is the right thing to do. So, despite the messiness of this moment, I’m standing in solidarity with all of the Earth protectors around the world and with all the young people who feel desperate for their futures.”
