Wouldn't aerosols reduce solar irradiance globally, hence reducing the rate of photosynthesis globally...which further reduces natural CO2 capture? How would that help?

No. It can be localized (for large scales of localized).

Also, we are finding through putting solar farms on crop fields, sun light is not the limiter on photosynthesis for many plants. Many plants get too hot, loose moisture, and photosynthesis less.

Nah, Sulfur compounds can lower albedo. That’s actually quite possibly what happened here and why we have sudden outlier acceleration.

Yea. They were basically burning the tar like leftovers from fuel distillation and there was a lot of heavy tankers moving from East Asia to the US.
