Sucking the carbon out of the sky
Listen now
Description
Most of our efforts to fight climate change, from electric cars to wind turbines, are about pumping fewer greenhouse gases into the atmosphere. But what if we could pull out the gases that are already there? Akshat Rathi, a reporter at Bloomberg with a doctorate in chemistry, knows more about this technology, called “direct air capture,” than just about anyone. He follows companies like Carbon Engineering and Climeworks that are trying to figure out how to take regular air and pull carbon dioxide out of it. If their plans work, they could mean a world with net negative emissions: less carbon in the sky than there is right now, and a cooler planet. But his reporting has also highlighted how elusive carbon capture can be, and how tricky it can be to make the tech work at an affordable price. Rathi and Vox’s Dylan Matthews discuss how direct air capture works, how it’s different from capturing carbon at a fossil fuel plant, and the struggles of one direct air capture company in particular.     Read more of Akshat’s work here: Inside America's Race to Scale Direct-Air Capture Technology - Bloomberg Crushed Rock Could Capture Billions of Tons of Carbon Dioxide - Bloomberg Britain Is Getting Ready to Scale Up Negative-Emissions Technology - Bloomberg Planting Trees Isn’t a Simple Climate Change Solution It Seems - Bloomberg The story behind the world’s first large direct air capture plant — Quartz (qz.com) The ultimate guide to negative-emissions technologies — Quartz (qz.com)   Host: Dylan Matthews (@DylanMatt), senior correspondent, Vox  Producer:  Sofi LaLonde (@sofilalonde)   More to explore: Subscribe to Vox’s Future Perfect newsletter, which breaks down big, complicated problems the world faces and the most efficient ways to solve them.

Climate scientist Kimberly Nicholas co-led a study that showed the single most effective thing an individual can do to decrease their carbon footprint is have fewer kids. Despite that finding, she still says that people who really want to have kids should go ahead with their plans. She explains...

In an ideal world, cutting carbon emissions would be enough to stop global warming. But after dithering for decades, the world needs a back-up plan. Kelly Wanser is the leader of a group called SilverLining that works to promote research into what it calls “solar climate intervention.” Also...
