๐ŸšจTired of drowning in climate science papers?

๐ŸŽง Remove & Reflect Podcast does the digging for youโ€”turning research & reports into short, sharp episodes on #CDR & #SRM.

YouTube:youtube.com/@removeandreflโ€ฆ

Spotify:open.spotify.com/show/0dxuwkOuHโ€ฆ

Check out some must-listen episodes:๐Ÿงต1/12
This episode dives into a radical proposal: using a buried nuclear explosion on the seafloor to break up basalt & speed up carbon removal via Enhanced Rock Weathering. The goal? Sequester 30 years of global CO2.

This episode unpacks a preprint by Hosea Olayiwola Patrick drawing lessons from COVID-19 for solar geoengineering.

Canada Nickel partnered with NetCarb to scale mineral carbon sequestration at Crawford. NetCarb's tech could boost COโ‚‚ uptake 10โ€‘fold to 10โ€“15โ€ฏMt/year, vs 1.5โ€ฏMt via Canada Nickel's proprietary IPT Carbonation.

๐ŸšจA new study [preprint] shows that injecting sulfur at 50km could make #SolarGeoengineering much safer.

It cools the planet more effectively, speeds ozone recovery & avoids stratospheric disruptions. This could be done using a fleet of clean, reusable H2 rockets.

DETAILS๐Ÿงต1/10 Image
2/ SAI involves spraying SOโ‚‚ into stratosphere, where it forms aerosols that reflect sunlightโ€”cooling Earth. It mimics volcanic eruptions like Mt. Pinatubo (1991), which temporarily cooled the planet.

But current โ€œSAI modelsโ€ inject SO2 at a rate of 10 Tg/yr at ~25km altitude.
3/ But Injecting at 25 km creates problems

Aerosols accumulate in the tropical lower stratosphere, causing up to 6ยฐC warming in that layer.

This disturbs jet streams, increases stratospheric water vapor, and delays the ozone layerโ€™s recoveryโ€”by 25โ€“55 years in Antarctica. Image

๐ŸšจA new study has revealed for the first time that ancient carbon, stored in landscapes for thousands of years or more, can find its way back to the atmosphere as COโ‚‚ is released from the surfaces of rivers at a rate of 1.2 billion tonnes per year.

Details๐Ÿงต1/8 Image
2/ To understand the true source of river COโ‚‚, researchers compiled a global dataset of 1,195 radiocarbon measurements of dissolved inorganic carbon (DIC), COโ‚‚ & CHโ‚„ from rivers & streams.

This let them determine whether the emitted carbon was modernโ€”or much older. Image
3/ Using radiocarbon signatures (ยนโดC), they found that 59% of river COโ‚‚ emissions come from "old" Cโ€”millennia-old soil carbon & even petrogenic carbon (rock-derived, >55,000 years old)

Only ~41% came from recent biological sources like plants & microbes (decadal carbon). Image
