CO₂ does play a role but it is not leading temperature changes, instead the atmospheric CO₂ concentration increases when the oceans warm up due to ${reasons} which in turn can lead to an increase in surface temperature - as to whether this is the case depends on many other factors like ocean currents, cloud coverage and more. The opposite is true as well, cooler oceans absorb more CO₂ which leads to a decrease in atmospheric CO₂ concentration which in turn can (but does not have to, see above) lead to a surface temperature decrease.
