๐ŸšจCan aeosols counter AMOC collapse?

A NEW study suggests Stratospheric Aerosol Injection (#SAI) could help prevent the decline of the Atlantic Meridional Overturning Circulation (#AMOC), but only if aerosols are injected in the appropriate latitude & hemisphere.

DETAILS๐Ÿงต1/12 Image
2/ The AMOC is a key component of Earthโ€™s climate system, transporting heat and nutrients across the Atlantic.

Its decline, already underway, is projected to accelerate under global warming, possibly approaching a tipping point this century. Image
3/ Using CESM2(WACCM6), Bednarz et al. ran sensitivity experiments with SOโ‚‚ injections at latitudes from 45ยฐS to 45ยฐN.

Each scenario injected 12 Tg-SOโ‚‚/yr (2035โ€“2069) to test how SAI location affects AMOC stability.

๐ŸšจEnhanced Rock Weathering (#ERW) could remove up to 700 Mt COโ‚‚ by 2070 in the UK if quarry production scales 5โ€“10ร—.

Larger extraction sites boost efficiency but raise major social, logistical & policy challenges.

A new @CommsEarth study models the trade-offs.๐Ÿงต1/11 Image
2/ ERW involves spreading crushed silicate rocks on croplands to capture COโ‚‚.

While previous studies examined its chemistry & agronomic benefits, this work focuses on the supply chain: can the UK sustainably scale rock extraction to meet net-zero needs?
3/ The authors model deployment from 2025โ€“2070 under 3 supply scenarios:

Low (32 Mt rock/yr), medium (97 Mt rock/yr) & high rock (166 Mt rock/yr) demand with variations in whether expansion relies on active, inactive, or new quarries. Image

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
