I think we'll find the 'greenhouse climate change' is a more complicated problem we will find many other issues reflective atmospheric particuate polution, ozone & other atmospheric chemical reactions etc.
A solutution to increased co2 levels would be to drop spores or seed the oceans to take up extra carbon dioxide out of the air. A small plankton that will also feed fish/wales & contirbute to the food chain.
I agree that the facts point to co2 causing warming of the planet but all this carbon dioxide has been in the air before. We could'nt be efficient enough to get it all out of the ground. How much oil/coal/gas must there be under the oceans that we'll never get. Planton in the ocean will increase in number consuming the extra carbon using sunlight. They then die & drag it to the bottom of the ocean. Remember the ocean is by far the greatest area on the planet.
We may decide to drop particulate air matter over areas like greenland or antartica to decrease temperatures & stop melting.
