You first have to assume that there is 'corrective action' that can be taken.  I have yet to see any publication as to what that might be.

The only thing coming from the scientists is that adding more Co2 and Methane etc. is a 'bad thing'.  

What specific effect continuing the 'bad thing' at its current rate or increasing or reducing the 'bad thing' might be has not yet been determined.  

What, if any 'corrective action' can be done and what that might result in over any particular time frame is a mystery at this point.

The scientists must have infusions of research dollars to answer any of those currently indeterminate questions.  

How many dollars and under what circumstances is also a mystery.
