Yes that’s definitely the preeminent primary hypothesized reason. /s

  Yes, it is, and your snarky response misses the point and misunderstands my comment. Obviously CO2 and other greenhouse gas emissions are what's driving climate change. But climate scientists have been surprised by the recent (like post-pandemic) big spike in heat, especially in the North Atlantic, and they hypothesize that low sulphur shipping rules that went into effect in 2020 reduced the global warming "masking effect" that these aerosols previously had: https://www.carbonbrief.org/analysis-how-low-sulphur-shipping-rules-are-affecting-global-warming/ https://www.carbonbrief.org/analysis-how-low-sulphur-shippin...

    Your own source contradicts you. > Given that there will be a lagged response from the climate to the shift to low-sulphur marine fuel, it is reasonable to expect less than half of the warming resulting from the 2020 regulations to have materialised by 2023, likely only in the hundredths of a degree globally. > This is unlikely to be sufficient to explain the spike in global sea surface temperature in recent weeks, which is around 0.2C above the prior record for this time of year.
