At best very temporary. The problem is carbon is being released via fossil fuels and the refinement of various types of ores for industrial uses. Cement making for example is a large contributor. This becomes part of an increased carbon cycle in the Hydrosphere. It takes nature hundreds of millions of years to lock away the carbon. To really make a difference plant material has to be sunk into swamps were it turns into peat and finally into coal after 100 million years or so.
Anthropomorphic global warming became broadly accepted around WW2 when high altitude research revealed Angstrom's error. There wasn't so much concern at the time because industrial activity was much lower than today. For example the release of carbon via industrial activity is six times higher pa today than it was in 1950.
Arrhenius atmospheric CO2 figure of 560 ppmv will now be reached before the century is out rather than the 3,000 years he thought it would take when he first proposed AGW.
The greatest risk is when levels of 800 ppmv are reached in as little as two centuries. This is the end of healthy atmosphere for Man and other advanced mammals and increasing levels beyond 800 ppmv will lead to their extinction.
