We are currently doing more, not less SRM than in the past because we don't reduce CO2 aka populations & consumption, we increase it. Doing even more SRM while we also increase the necessity for it - is an existential fallacy. Misinterpretation of #IMO2020 implications. We need R&D to show this?

Multi-year La Niña–El Niño transition influenced Earth’s extreme energy uptake in 2022–2023 - Nature Geoscience The extreme Earth heat uptake in 2022–2023 was mainly driven by the transition from multi-year La Niña to El Niño and a positive energy imbalance linked to human-induced warming, according to multi-mo...

A second opportunity to examine the cloud reduction effects from shipping fuel pollution measures has revealed that the 80% cut in sulphur emissions reduces cloud droplet formation by 67%.

Tempo fa avevo fatto un lungo post su #IMO2020 e i suoi effetti sulla recente accelerazione del riscaldamento climatico. Adesso è uscito un paper di James Hansen (uno dei più grandi climatologi esistenti) a riguardo, vi consiglio di leggerlo.

After 2020 and the IMO2020 emissions measures the Absorbed Solar Radiation rapidly increases out of step with the PDO cloud enhancing changes which should have spurred a decrease of Absorbed Solar Radiation.

The large role of declining atmospheric sulfate deposition and rising CO2 concentrations in stimulating future wetland CH4 emissions About 8 to 15% more aggressive cuts to anthropogenic methane emissions are required to meet the 1.5° and 2°C warming goals.

Reducing sulphate aerosol pollution will save millions of lives. We know however that the clean-up is accelerating global warming. In another cruel twist, it is also increasing wetland methane emissions.

Radiative forcing from the 2020 shipping fuel regulation is large but hard to detect - Communications Earth & Environment Reductions in aerosol cooling as a result of shipping fuel regulations implemented in 2020 led to substantial positive radiative forcing globally, but this change is difficult to detect against a back...

Stoma closing highest UV Levels after 💯 years. Mayor food and carbon cycle disruption from termination shock. ⚡️ #imo2020

So aus historischen Gründen seit über einem Jahrzehnt geht die akademische Diskussion zu den Aerosolen schon!

Das negative Forcing könnte doppelt(!) so hoch sein. #imo2020
