If we accept Warmist claims about the accuracy of temperature and CO2 proxies we get some very awkward findings about long-term trends
During the Ordovician, CO2 was more than ten times higher than at present. Global temperatures ranged between very hot and an ice age. We can state with 100% certainty that as CO2 increases, temperatures will either go up, go down, or stay the same.
