🚨🆕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."
🧵
"#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
"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
"The volume of #CDR in 2050
is also substantially correlated to the timing of #NetZero CO2." 4/7
"The robustness of the analyzed relationships was evaluated by comparing different scenario filtering and data-cleaning approaches." 5/7
"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.

🚨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.
3/ Basically, the paper builds on the science of Milankovitch cycles which is slow, natural variations in Earth’s orbit and tilt that have triggered past ice ages.
These cycles show that even slight orbital changes can dramatically affect climate.
CALL FOR RESEARCH PRESENTATION PROPOSAL—RFF and the Harvard Solar Geoengineering Research Program invite individuals to present research at their upcoming workshop
JPMorgan signed 13-year deal with CO280 to remove 450,000 tons of biogenic CO₂ from a U.S. pulp mill at under $200/ton—one of the largest and lowest-cost CDR deals to date.
