“Mitigating climate change requires cutting global carbon emissions to near zero.”
Matthew, “Irreversible climate change due to carbon dioxide emissions” published in the Proceedings of the National Academy of Sciences of the United States of America, December 16, 2008, states, “The severity of damaging human-induced climate change depends not only on the magnitude of the change but also on the potential for irreversibility. This paper shows that the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop.
So cutting carbon emissions does not really mitigate climate change.
As wikipedia points out, the first law of thermodynamics is often formulated by stating that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings
Cutting carbon emissions would gradually slow the temperature input but would not reverse the accumulation. The only way to reverse it is to short circuit the left side of the equation by converting the input heat to work and once that is under control then reverse the arrows on the right side by converting that heat, most of which is in the ocean to work as well.
Cutting emissions is at best a half measure.
