🚨PAPER—The Arctic’s frozen ground, permafrost, holds massive reserves of ancient carbon. As the planet warms, this carbon faces a dangerous release into the atm, accelerating climate change. Could solar geoengineering (#SRM) help save it? The answer is complex.
DETAILS🧵 1/7
2/7 Permafrost is warming faster than the global average, poised to unleash C stored for millennia. This creates a feedback loop—warming leads to more C release, which leads to more warming. Simulations show SRM could limit global warming to 1.5°C & slow permafrost thaw. But...
3/7 This research revealed that, at 1.5°C warming, permafrost loss is reduced by about 50% & carbon loss by about 33% due to SRM, compared to a high-emissions future (SSP5-8.5). However, significant losses still occur, even with SRM. By 2300, the damage remains substantial.

The US government has awarded $101 million in federal funding for five projects to support the development of CO2 capture, removal and conversion test centers.
🚨🏗Imagine a world where buildings don’t just house us but actively fight climate change🏗🚨
A new study reveals that CO2-storing materials in construction could capture 16.6 billion tonnes of CO2 annually — half of global emissions in 2021!

2/ The key lies in re-engineering materials like concrete, asphalt, wood, bricks, and plastics to store carbon. These materials are already used on a massive scale, making them ideal for turning the built environment into a carbon sink.
3/ The carbon-storing materials considered in this work include wood, bio-based plastic (replacing fossil derived materials), carbonateable cement, carbonate-based aggregate, biochar cement filler, portlandite brick, biomass fiber-based brick, and bio-based asphalt bitumen.
