The relationship between CO2 emissions and temperature increase is logarithmic, which means that you need to continually double CO2 emissions to see a linear increase in temperature.
When atmospheric CO2 concentration was low it didn't take much to double it and so you could readily affect increases in temperature, but the more CO2 producing capacity we add the harder it gets to double, and we are already at the point where doubling output is no longer feasible, in fact it would require such a huge GDP growth to get another doubling that temps are pretty much guaranteed to plateau where they are.
Put another way, when you have a dollar it's easy to double it to get two, when you have ten thousand dollars it's not so easy to double it to get twenty thousand dollars.
