We already know that major volcanic eruptions and meteor impacts can cause short term decreases in worldwide temperatures because of dust particles high in the atmosphere blocking sunlight. Could this be done in a controlled way, as a temporary solution?

There are some theories around injecting sulfur dioxide or water vapour into the upper atmosphere that woul provide cooling. Personally I think some sort of geo-engineering will happen before the necessary cuts in CO2 can occur.

Still doesn't address ocean acidification and could create a whole slew of us intended consequences but is very cheap to do relative to the cost of actually transitioning away from CO2 while brining developing nations out of poverty.
