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
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:
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.
Under SAI, global temperatures would be lower than in the SSP2-4.5 climate change scenario.
This affects malaria transmission by shifting EIR toward lower intensity values—meaning fewer infectious mosquito bites.
*Cooler climate = lower EIR
5/ The length of the malaria transmission season (LTS) and overall malaria cases are also projected to decline under SAI compared to SSP2-4.5. This suggests SAI could mitigate some malaria risks associated with warming climates.
6/ Which Countries See the Biggest Changes?
The biggest reductions in EIR (🦟infectivity) from 2045-2069 are projected in India & Bangladesh—the most populous and malaria-prone nations.
Other South Asian countries (Afghanistan, Iran, Bhutan, Nepal, Pakistan) also see declines.
A new study funded by @DegreesNGO suggests Stratospheric Aerosol Injection (#SAI) could lower malaria risk in South Asia by shortening transmission seasons & lowering mosquito infectivity.

2/ Rising temps are expanding malaria-prone areas. This study examined malaria risk in 7 climate-vulnerable South Asian countries—Afghanistan, India, Iran, Bangladesh, Bhutan, Nepal & Pakistan—under moderate climate change (SSP2-4.5) vs. a cooler world with SAI (ARISE-SAI-1.5).
3/ Using a dynamic malaria model, researchers analyzed 3 key transmission indicators:

Brazil secured a $247M investment to restore 54,000 hectares of forests in the Amazon and Cerrado. This initiative will cut 7.75M tonnes of CO₂ and create 21,000 jobs.
@_Capture6, a CA-based company whose integrated system converts waste brine into both fresh water and carbon removal solutions, raised $27.5M in Series A and project funding.
A 16-year experiment in Panama shows that tree diversity—not just tree planting—supercharges carbon storage. Diverse forests stored 57% more carbon than monocultures.
DETAILS:🧵1/9
2/ The study, published in Global Change Biology, analyzed 16 years of data from the Sardinilla experiment in Panama.
Researchers planted forests with 1, 2, 3, or 5 tree species and tracked how carbon moved through the ecosystem.
3/ KEY FINDINGS
More species, more carbon:
•5-species forests stored 57% more carbon in tree biomass than monocultures (35.7 vs. 22.8 Mg C/ha).
•These benefits strengthened over time, even under climate stress.
