There's this idea called aerosol cooling. The idea is we put lots of particles in the air which have an effect of cooling the earth. Where cooling is a temporary ~1C reduction.

There's a hypothesis that this same effect already occurs from anthropogenic sources: namely, pollution. Our global response to COVID-19 unarguably will reduce the amount of pollutant aerosols in our atmosphere. The degree to which that will effect the climate and near term temperature is unknown at least to me, however.

So, if we shut things down is this going to heat us up? Are we about to have a bad time? Is this plausible? If not, why not? I'm kinda spooked.

A wiki snippet for extra context:
>Regional warming: Based on the results of the 2014-2015 Geoengineering Model Intercomparison Project, a model with a standard stratospheric aerosol injection scenario, temperatures in the tropics would cool, and higher latitudes warm, ice sheet, and Arctic sea ice decline would still continue, albeit at a reduced rate. Extreme temperature anomalies would also still increase, but to a lesser degree. In regards to these model results, the author of the study Alan Robock noted:

>If geoengineering were halted all at once, there would be rapid temperature and precipitation increases at 5–10 times the rates from gradual global warming.
