🚨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

🚨AstroCool is a proposed emergency geoengineering plan by inventor David Chaum.

It involves mining moon dust & launching it into a space orbit between the Sun & Earth to shade the planet & restore pre-industrial temperatures.🧵1/12

#SRM #SolarGeoengineering #ClimateSolutions Image 2/ AstroCool (the “Plan X” initiative) was unveiled by Chaum as a backup climate fix.

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

How? By adding alkaline rocks like olivine—turning treatment plants into climate allies. A quick thread🧵1/7

#CDR #CarbonRemoval #ClimateSolutions Image 2/ Carbon dioxide removal is about pulling CO₂ out of the air and locking it away.

One such technique, OAE, helps the ocean absorb more CO₂ by increasing its alkalinity, which reduces surface ocean acidity. Image

🚨How much land will CDR take?

New research shows that large-scale #CDR—essential for 1.5°C or 1°C climate goals—could demand vast land areas if we rely on energy crops, potentially up to 10% of today’s cropland. But tech-based sol could greatly reduce that burden.

DETAILS🧵1/8 Image 2/ Most CDR plans today focus on bioenergy with carbon capture (#BECCS), reforestation, and afforestation. These options are land-intensive. This study compares them with other portfolios that prioritize low land use, low cost, high tech readiness, and security.
