Pollution Cuts Have Diminished 'Ship Track' Clouds, Adding To Global Warming (science.org) 134
Paul Voosen writes via Science: Regulations imposed in 2020 by the United Nations's International Maritime Organization (IMO) have cut ships' sulfur pollution by more than 80% and improved air quality worldwide. The reduction has also lessened the effect of sulfate particles in seeding and brightening the distinctive low-lying, reflective clouds that follow in the wake of ships and help cool the planet. The 2020 IMO rule "is a big natural experiment," says Duncan Watson-Parris, an atmospheric physicist at the Scripps Institution of Oceanography. "We're changing the clouds."
By dramatically reducing the number of ship tracks, the planet has warmed up faster, several new studies have found. That trend is magnified in the Atlantic, where maritime traffic is particularly dense. In the shipping corridors, the increased light represents a 50% boost to the warming effect of human carbon emissions. It's as if the world suddenly lost the cooling effect from a fairly large volcanic eruption each year, says Michael Diamond, an atmospheric scientist at Florida State University.
The natural experiment created by the IMO rules is providing a rare opportunity for climate scientists to study a geoengineering scheme in action -- although it is one that is working in the wrong direction. Indeed, one such strategy to slow global warming, called marine cloud brightening, would see ships inject salt particles back into the air, to make clouds more reflective. In Diamond's view, the dramatic decline in ship tracks is clear evidence that humanity could cool off the planet significantly by brightening the clouds. "It suggests pretty strongly that if you wanted to do it on purpose, you could," he says. The findings are available in a new preprint in Atmospheric Chemistry and Physics (ACP).

What has actually happened is the the short-term effects of sulfates has dissipated and as a result, we are experiencing the full impact of our atmosphere. Ships generate and incredible amount of CO2 (one ship can emit the same as millions of cars) so this is an improvement. So yes, in the short-term it's warmer but CO2 it's not emitting will make it even hotter in the long-term.

Blowing sulphur particulates into the atmosphere causes 'global dimming', which reduces the energy input into the system, keeping temperatures down despite the increasing levels of greenhouse gasses. However, the entire process and its results are bad for the environment in ways other than mere temperature.
The simple answer appears to be 'throw something else up there that is not bad for us that will still block some sunlight', but the problem is this is too simple an answer.
I can't see that doing anything but allowing the short-sighted to continue pumping CO2 into the air and heating up the planet, which means the aerosol injection becomes permanent if we want to have comfortable temperatures. And CO2 does more than heat us up - it is acidifying the oceans and I'm going to make a wild-ass guess that there are other less well-known effects we should also be concerned about.
We may well need to do some solar shielding as a stop gap measure, but if we're not sucking the last 140 years of CO2 production out of the atmosphere and sequestering it (and cease to keep adding more, of course), we're delaying the inevitable and making it worse at the same time.
