It’s called geo engineering and problems would include:

1) ocean acidification

2) a sky white rather than blue

3) severely alerted rain patterns

4) a very sharp positive climate transient if for some reason you stop doing it

5) etc etc

Also most climate scientists we simply cannot control a system that chaotic

Also, injecting sulphuric acid at large scale in the atmosphere might not be such a great idea.

But yeah, chemtrails would work.
