Scientists have discovered that the recent spike in global temperatures may be caused by a reduction in sulfur dioxide pollution from shipping vessels. Ships have long emitted sulfur dioxide, which cools the planet by seeding clouds and reflecting sunlight. However, new regulations that limit sulfur in ship fuels took effect in 2020, leading to a loss of this cooling effect equivalent to a large volcanic eruption each year. Models show this reduction in sulfur dioxide pollution can explain the extra warming seen in the North Atlantic. While pollution is bad, the new regulations provide a natural experiment that gives insight into how intentional geoengineering could potentially combat climate change in the future.

Right, but their point was kind of about side-effects we're not aware of at the time. So that's kind of the entire point, that we think there are no negative side effects only to later find out we were wrong.

So that doesn't really address what they said at all.

Exactly this. We think we know everything when we start doing stuff. But after a while we found out we where wrong and fucked up.
We don't fully understand/comprehend nature and how it all interacts. We shouldn't be so ignorant to think we do understand it.

If only we were allowed to study this approach without so much immediate reflexive opposition.
