I’ve seen some people putting out charts showing the kind of effect that the massive reduction in sulphur content in shipping fuel is having, and this is the first El Niño we’ve had since that happened (around 2020). It is an improvement, but the sulphur dioxide pollution had the side-effect of basically masking some of the global warming that had already happened by blocking some of the solar irradiance, especially over the ocean. This is apparently changing stuff like cloud formation and seems like it might be a big part of the puzzle. Of course, reducing this pollution is overall good, even if one of the side effects of it being in the atmosphere was somewhat positive… EDIT: Although some analysis such as this - https://www.carbonbrief.org/analysis-how-low-sulphur-shipping-rules-are-affecting-global-warming/ https://www.carbonbrief.org/analysis-how-low-sulphur-shippin... - suggests while there is a big effect, the effect shouldn’t be anywhere as large as what we’re seeing.
