🚨NEW STUDY: We could trap 18 billion kilos of CO₂ a year by tweaking how we treat our wastewater.

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.

🚨A recent field study conducted over the Great Barrier Reef has provided key insights regarding sea spray aerosols (SSA).

For the first time, it shows that SSA can reach the cloud base height, advancing Marine Cloud Brightening (#MCB) research.

DETAILS🧵1/8 Image 2/ MCB is a proposed climate intervention that aims to reflect more sunlight by enhancing marine clouds.

The concept relies on artificially generated sea spray aerosols (SSA) at the ocean surface and their transport in sufficient quantities to low-level maritime clouds.

Here’s the details:🧵1/9 Image 2/ Researchers spread finely crushed metabasaltic rocks across test plots in Browns Valley, California, in each of 3yrs.

Along with the crushed rock, some of the applications included compost or a combination of compost & biochar (burned pine & fir left over from local logging). Image

🚨A recent study shows that bottom trawling & dredging not only harm marine ecosystems but also reduce the ocean's capacity to sequester CO₂.

However, human activities like mobile bottom-contact fishing (e.g., trawling) and dredging are disturbing this natural carbon sink. Image

🚨🌋 A new UCLA-led study reveals surprising findings about the 2022 Hunga Tonga—Hunga Haʻapai underwater volcanic eruption. Despite fears it would push global temps past 1.5°C, it actually cooled the Southern Hemisphere by 0.1°C!

Here's why:🧵1/8
#SolarGeoengineering #Aerosols Image 2/ When Hunga Tonga erupted in January 2022, scientists expected the massive release of water vapor to trigger warming, but a key factor shifted: The eruption produced smaller sulfate aerosols that unexpectedly cooled the atmosphere!
