Because absent a near halt on CO2 emissions they are worthless. We will keep emitting past the point where they are useful and will have a much steeper cliff to fall off. If you have ever seen Futurama's "Crime of the Hot", think of dropping the increasingly large ice cube as the analogy. If we solve emissions, then I think everyone agrees we can look at accelerated weathering and other sequestration strategies.
