Climate change impacts are here, but public support for action remains polarized. Which climate messages move people? In a ~13,500-person megastudy, we tested 10 of the most-cited messages. Six increased pro-environmental attitudes in the U.S.—but only by 1–4 percentage points. 🧵

Can AI voter guides help voters decide while remaining accurate, nonpartisan, and trustworthy? Very grateful to @stanfordimpactlabs.bsky.social for a new grant supporting our next work on this (building on work led by Joe Mernyk & Jonne Kamphorst): bsky.app/profile/robb...
