Young people in Indiana and across the globe will rally for action against climate change on Friday. But how effective are things like marches and protests?
Research from Indiana University shows they may change people’s attitudes about the climate movement.
IU environmental communications scientist Nathan Geiger was part of a team that surveyed people who watched the March for Science and the People’s Climate March.
He says before the marches, bystanders were skeptical that people could come together to work on big problems like climate change.
