2023 planetary heat uptake from termination shock of inadvertent geoengineering?
Shipping fuel regulations in 2020 that reduced sulfur dioxide emissions by 80% led to substantial warming over parts of the oceans, according to simulations with Earth system, machine learning, and energy balance models, suggesting a termination shock after marine cloud geoengineering could be severe.
The combination of modeled \(\varDelta {N}_{d}\) and observed relationship for LWP and cloud fraction adjustments show that IMO2020 as a termination shock for the inadvertent geoengineering experiment of shipping emissions has had a non-trivial warming effect on the climate. The National Academy of Sciences, Engineering, and Medicines 4 recommended the impact of any outdoor solar radiation management experiment on global mean temperature to be within 1 × 10 −7 K. The forcing magnitude of this inadvertent shock has exceeded this limit by a large margin.
