๐ŸšจA new CSIRO-led study finds Australia can achieve net-zero emissions cost-effectively by 2050 if it acts early.

Rapid decarbonisation of electricity, scaled #CarbonRemoval, and strategic land offsets are central to success.

Details๐Ÿงต1/9 Image
2/ The research adapts the IEAโ€™s global net-zero scenarios to Australiaโ€™s economy using an integrated economicโ€“energy model.

It compares a Rapid Decarbonisation pathway, consistent with limiting warming to 1.5 ยฐC, with a Stated Policies path leading to ~2.6 ยฐC by 2100. Image
3/ Electricity emerges as cornerstone. In rapid pathway, coal is 85% retired by 2030 & fully phased out by 2035.

Renewables supply ~90% of generation by 2030, cutting emissions intensity to ~15% of 2020 levels & enabling deeper decarbonisation across various sectors. Image

๐ŸšจNew research out on US public perceptions of #SolarGeoengineering:

More Americans oppose SRM research than support it, and 1 in 5 believe government-led atmospheric modification is already underway.

DETAILS๐Ÿงต1/11 Image
2/ Using 64 interviews, 10 focus groups, and a survey of 3,076 Americans, the study found strong initial rejection of solar radiation modification (#SRM) as a research priority.

Skepticism, fear of unintended consequences, and concern over โ€œplaying Godโ€ were dominant themes. Image
3/ Only 32.6% supported further SRM research. A notable 43.7% opposed it. For comparison, support was ~80% in similar studies from a decade ago. Enthusiastic support is now virtually nonexistent in qualitative responses. Image

๐ŸšจHow does #SolarGeoengineering affect air pollution & public health?

New study using a cutting-edge Earth system model shows that #SAI has only modest effects on PMโ‚‚.โ‚… & ozone-related mortality & these impacts are mostly due to climate shifts, not aerosol deposition.๐Ÿงต1/8 Image
2/ Using CESM2-WACCM6 simulations across three scenarios (SSP2-4.5 baseline, ARISE-SAI-1.5, ARISE-SAI-1.0), the study quantifies global mortality attributable to ozone (Oโ‚ƒ) & fine particulate matter (PMโ‚‚.โ‚…) under future SAI deployment targeting 1.5ยฐC and 1.0ยฐC warming levels.
3/ Findings:

In the ARISE-SAI-1.5 scenario, maintaining global mean temp at 1.5ยฐC above pre-industrial levels via SAI results in:

- 1.26% reduction in ozone-related mortality

- 0.86% increase in PMโ‚‚.โ‚…-related mortality during 2060โ€“2069, relative to SSP2-4.5. Image
