It has to do with timescales.

As an example, consider the world's population. It took only 70 years for the world to triple it's population (and some countries have seen a 6-fold increase in their population in that time).

There is no ethical way of exactly reversing that and reducing the population by a factor of 3 in 70 years. It will take at least 200, if not longer.

To get our carbon levels down to 1970 levels will take us much longer than 50 years. In the meantime the world will continue heating and secondary effects will kick in.
