If you could lower the temperature of the planet by up to 1 degree by say, injecting sulphur into the upper atmosphere, that would still be a short term solution unless carbon emissions are reduced, because eventually the ever increasing amount of carbon will result in even higher temperatures, despite the geoengineering efforts. Even worse, if the geoengineering efforts should stop, either due to lack of resources (ie. running low on sulphur) or because it turns out the geoengineering has worse side effects ( like say, acid rain) then the temperature would rise even more catastrophically quickly.
The current effort that is being used, creating clouds from brine has the obvious possible side effect of causing salty rain, which if the clouds happened to blow over farmland and would be obviously not a great thing for agriculture.
The only real solution is to reduce carbon and methane emissions so we don't keep increasing the temperature further. The longer that is put off, the worse it will be for everyone, but particularly for those who can not afford to adapt how or where they live. I personally will be fine - I can easily afford to move to a house on a hill somewhere if my current coastal location starts to flood. Most people living in say, Bangladesh, or a corn farm in Iowa who depends on current rainfall patterns probably will not.
