🚨🆕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 do political affiliations shape attitudes toward #SolarGeoengineering?🚨

A conjoint experiment with 2,123 US voters finds that partisanship outweighs message framing—meaning who delivers the message matters more than what the message says.

DETAILS🧵1/9 Image
2/ The discourse on SG as a climate solution is evolving, but public perceptions—especially in the polarized US landscape—remain underexplored. This study () examines how different narratives & partisan sources influence attitudes.nature.com/articles/s4416…
3/Researchers tested 3 SG narratives:

-Complementary: SG as an add-on to emissions cuts

-Substitutive: SG as a standalone climate solution

-Moral hazard: SG as a risky distraction

🚨A breakthrough in carbon storage!🚨

Scientists at @NorthwesternU have developed a NEW carbon-negative building material using seawater, electricity & CO₂.

How does it work? And how much CO₂ can it store? Read on:🧵1/12 Image
2/ This study expands on earlier research that focuses on storing CO2 in concrete [nature.com/articles/s4324…] & using electricity to treat seawater for cementing marine soils [nature.com/articles/s4324…].
Researchers are now injecting CO2 while applying electricity to seawater in lab. Image
Image
3/ PROCESS

To generate the carbon-negative material, the researchers started by inserting electrodes into seawater & applying an electric current. The low electrical current splits water molecules into hydrogen gas (a clean fuel with various applications) & hydroxide ions. Image

🚨A new hope or a phantom menace?🚨

A global survey of 30,000+ people across 30 countries reveals how emotions—hope, fear, anger—shape perceptions of climate change & support for interventions like #CDR & #SRM.

Does hope drive action—or is fear the real motivator? Read on:🧵1/8 Image
2/ To measure “climate emotions” globally, researchers (@ChadM_Baum, Elina Brutschin, Livia Fritz, @BenjaminSovaco1) from Aarhus University & IIASA surveyed adults in 19 languages from Aug–Dec 2022.

Here are some of the findings: Image
3/ Among the 12 most hopeful countries about climate change, there were 11 developing and emerging economies of the Global South (including Nigeria, Kenya, India and Indonesia).

The only Global North country in this group? The United States. Image
