🚨Georgia Tech researchers have developed a low-cost method to pull CO₂ from the air (#DAC) using cold temperatures and common materials, potentially slashing capture costs to ~$70 per ton and expanding where Direct Air Capture can work. #CDR

DETAILS🧵1/9 Image 2/ DAC is a critical tool for fighting climate change, but it’s been too expensive to scale.

Current systems often exceed $200 per ton of CO₂ captured, partly due to the high energy needed to run them.

🚨From Air to Stone🚨

New study revealed that Kenyan fig trees can literally turn parts of themselves to stone, using microbes to convert internal crystals into limestone-like deposits that lock away CO2, sweeten surrounding soil & still yield fruit. #CarbonRemoval

DETAILS🧵1/8 Image 2/ Some Kenyan fig trees, like Ficus wakefieldii, store CO₂ not just as organic matter (wood/leaves) but also as calcium carbonate (CaCO₃) - the same mineral as chalk or limestone.

This process is called the oxalate-carbonate pathway (OCP).

🚨What if we bet too much on future carbon removal tech and it doesn’t deliver?

New study shows that over-relying on #CDR like DACCS & BECCS could let fossil fuel emissions continue longer, delay action, and raise costs later.

Key findings🧵1/9 Image 2/ Many net-zero plans assume large-scale CDR. But techs like direct air capture (DACCS) & bioenergy with CCS (BECCS) are tiny today and scaling them is risky due to land, energy & cost barriers.

🚨A 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.

DETAILS🧵1/10 Image 2/ SAI involves spraying SO₂ into stratosphere, where it forms aerosols that reflect sunlight—cooling Earth. It mimics volcanic eruptions like Mt. Pinatubo (1991), which temporarily cooled the planet.

But current “SAI models” inject SO2 at a rate of 10 Tg/yr at ~25km altitude.

🚨A 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 CO₂ is released from the surfaces of rivers at a rate of 1.2 billion tonnes per year.

Details🧵1/8 Image 2/ To understand the true source of river CO₂, researchers compiled a global dataset of 1,195 radiocarbon measurements of dissolved inorganic carbon (DIC), CO₂ & CH₄ from rivers & streams.

This let them determine whether the emitted carbon was modern—or much older. Image

🚨A NEW study explores a theoretical #geoengineering approach to combat global warming — by altering Earth’s orbit.

Simulations suggest that shifting Earth ~5.8% farther from the Sun could cool the planet by roughly 7K, effectively offsetting projected warming.

DETAILS🧵1/10 2/ Climate models suggest global temperatures could rise by 7K by 2100, driven by greenhouse gas emissions.

This study asks: what if, instead of changing the atmosphere, we changed our position in space?
Specifically: increase Earth’s orbital radius.

🚨Can a single particle both reflect sunlight and capture CO₂—offering a two-in-one tool for climate intervention?🚨

In a new study [preprint], researchers tested the idea with zeolite aerosols. Here's what they found:🧵1/6

#SolarGeoengineering #CDR #ClimateTech Image The concept: Inject aerosols into the stratosphere that not only reflect sunlight (like standard #SAI) but also adsorb CO₂ from the air.

Zeolites, known for their CO₂-trapping ability, seemed like a candidate for this dual function. Image

It proposes using centrifugal lunar launchers and robotic “droid” satellites to fling regolith into the Sun–Earth L1 point, creating a sunshade that cuts incoming sunlight. Image
