Summary

Humans must dramatically rein in greenhouse gas emissions in order to slow the planetary warming caused by centuries of fossil fuel combustion. But even if we accomplish that through major reforms to our power supply, food systems, industrial industries and more, we still need to remove huge amounts of carbon already in the atmosphere to stave off the worst impacts of climate disruption. This is no easy task. We need to explore every option – both nature-based solutions and tech solutions. In a two-part series, we look at both categories. First up, the natural mechanisms for carbon capture and storage, from forests to peat bogs to kelp beds. Guests: Ugbaad Kosar, Deputy Director of Policy, Carbon180 Edward Struzik, author, Swamplands: Tundra Beavers, Quaking Bogs and the Improbable World of Peat Bren Smith, Co-Executive Director and Owner, Thimble Island Ocean Farm Benjamin Preston, Senior Policy Researcher, RAND Corporation Learn more about your ad choices.

0:00.0	Hi, just leave on work now. Sorry, it's a bit loud. Um, basically, so I was thinking we could get Mackeys tonight. Had a big Mac on my mind all day and delivery fee on the app is now from 99P. So you win? Of course you are. Love you. Bye. Exclusively on the McDonald's app. 18 plus service fee and small order fee may apply. Participating restaurants. Serving times and teas and fees apply. Hi, it's Greg Dalton. I'd like to hear your comments on the show,
0:23.9	topics we should cover, and guest suggestions. You can reach me at Greg at climate one.org.
0:30.1	This is Climate One. I'm Greg Dalton. To limit climate disruption, we need to pull vast amounts
0:36.7	of carbon dioxide out of the sky.
0:39.6	We're now in a place where focusing on emissions reductions alone is just not enough.
0:45.2	And as important as that is, we still need to do something about all of those legacy emissions that are out there already.
0:52.2	Nature already has many ways of doing this.
0:55.0	Peatlands, which represent only about 3% of the world's terrestrial surface,
1:00.0	store twice as much carbon as all the world's forests combined.
1:04.0	So as carbon storage reservoirs, they're unmatched.
1:08.0	So how can we maximize those powerful tools? If you were to take
1:12.5	less than 4% of U.S. waters to farm seaweed, you could offset the entire agricultural carbon
1:20.0	emissions of California. Can humans use and improve upon the Earth's natural methods of capturing
1:26.6	and storing carbon.
1:28.5	A new IPCC report out this week further details the gravity of our inaction on climate change,
1:34.8	predicting increasingly dire disruption to natural systems and billions of people around the world.
1:40.7	Many of these climate hazards are here now and are accelerating.
1:44.2	We really are sort of a tipping point on climate change.
1:47.0	I think people are realizing that the risks are very real, they're upon us, and we're behind in sort of getting out in front of this particular challenge.
1:55.0	Later in the show, we'll hear from one of the authors of the report, which strengthens the case for going beyond merely reducing
2:01.5	emissions. We need to start sucking existing carbon dioxide out of the sky. Ugbad Kossar is
2:08.3	Deputy Director of Policy at Carbon 180, a nonprofit focused on carbon removal. So we're talking
