NO. There is no link.
A theoretical link has been put forward in the theory of man-made climate change but no link has been demonstrated in thousands of years or even hundreds of thousands of years of data. The only significant relationship is when the Earth warms up at the end of an ice age more CO2 comes into the atmosphere about 800 years later. So if anything is happening it is that temerature drives CO2 some of the time.
