These machines suck climate-warming carbon right out of the air

Scientists are looking toward carbon removal or ideas to pull greenhouse gasses right from the atmosphere. NPR's Camila Domonoske joins us to talk about direct air capture, or machines that can pull carbon dioxide out of the atmosphere. And, as Democrats and Republicans go back and forth over border funding, The Washington Post's Arelis Hernández joins us to talk about what's really going on at the U.S.-Mexico border.
