Unfortunately neither the weather, nor the environment, are going to get cleaned up. I think this is a given. There has been a lot of talk, plans, agreements, promises, etc. but, in reality, not a whole lot to actually fix anything. This being the case eventually the geo-engineers will begin 'fixing' things. An interesting aside to this is the simple fact that, if they screw up, we will all die!
If you are not familiar with geo-engineering google "geo engineering" and read all about it.
