    As atmospheric carbon dioxide concentrations increase, the climate gets warmer. The warmer climate speeds up chemical weathering, which consumes carbon dioxide from the atmosphere (i.e. CO2 decreases) and mitigates the greenhouse effect, thus leading to a climate cooling.

    Option c is the answer. Rising temperature and more dissolved CO2 ( by rain carbonic acid formation.)will lead to increased weathering of crustal rocks as a result of faster reaction rates (temperature effect) and greater acidity. Enhanced weathering will use up the excess CO2 thereby cooling the climate.
