There seem to be only two things that we need answers to with regards to dealing with increasing CO2:
1. Can we capture CO2 and prevent it from affecting the climate in a safe way?
2. Could we create a large “blind” between the earth and sun to safely control how much sunlight hits the earth if the temperature gets too hot?
There have been advances in #1 and propositions for #2, but I think most either want to cast blame, bury our heads in the sand, or wallow in self-pity because they think we’re not capable of figuring out a safe solution and/or don’t believe that we could work together to accomplish it.
