If you want to reduce your carbon footprint, there are plenty of ways to do it: change your lightbulbs, wash your clothes in cold water, buy a fuel-efficient car, eat less red meat, carpool and so on. Texas Tech climate scientist Katharine Hayhoe offers those suggestions and more in the newest addition to her “Global Weirding” series.

If you’re feeling cynical, you might suspect those behavior changes aren’t enough to make a difference. And you’re right. To address global warming, Hayhoe says, people need to cut their own carbon footprints and work with others to do the same.

“The reality is, the government also must act,” she adds.

For her practical suggestions about making change on a large scale, watch the video.

Hayhoe’s “Global Weirding” series is produced by KTTZ Texas Tech Public Media and distributed by PBS Digital Studios. New episodes air on YouTube every other Wednesday.
