How Does Climate Respond to Different Forcings?
Global temperature responds in the same way to carbon dioxide as it does to methane or aerosol changes if the concept of effective radiative forcing is used to quantify the forcing strength.

Atlantic Circulation Consistently Tied to Carbon Dioxide
Past ocean surface conditions suggest that over the past 800,000 years, atmospheric carbon dioxide levels typically rose on millennial timescales when Atlantic overturning was weaker and vice versa.
