🚨🆕STUDY🚨
"The study explored the wide range in #CDR deployment volumes across 1.5°C compatible & high overshoot pathways by evaluating the links btw CDR & conceptually linked scenario aspects, via focus on CDR in 2050 & scenario properties related to reaching #NetZero CO2."
🧵 Image
"#CDR volumes
were further evaluated in terms of their relative and absolute contribution to total mitigation up until reaching
net-zero CO2, showing considerable variation across scenarios with a median relative contribution of around 20%."
2/7 Image
"The volumes of #CDR in 2050 and 2100 and the cumulative amount throughout the 21st century were most strongly correlated to the degree to which CO2 emissions are reduced as a means of reaching net-zero CO2."
3/7 ImageImage
"The volume of #CDR in 2050
is also substantially correlated to the timing of #NetZero CO2."
4/7 Image
"The robustness of the analyzed relationships was evaluated by comparing different scenario filtering and data-cleaning approaches."
5/7 Image
"Beyond filtering and cleaning, additional factors that influence #CDR deployment in scenarios, such as discount rates, carbon price trajectories, and scenario design choices," were also discussed in this study.

🚨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.
3/ The researchers modeled two total CDR targets:
• 500 GtCO₂ for a 1.5°C pathway
• 1750 GtCO₂ for a 1.0°C pathway

They included not just the land for CDR methods, but also for energy sources like solar and wind to run the full CDR-energy-industry system. Image

🚨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.
3/ A portion of the SSA that reaches cloud height can act as additional cloud condensation nuclei and modify cloud microphysical properties, potentially reducing the amount of solar radiation reaching the sea surface.
