During the winter, the primary driver of climate is sea surface temperatures. Every mainstream seasonal weather forecaster will tell you the same thing. During the summer, soil moisture also becomes important.
Until someone establishes a link between sea surface temperature and CO2, claims that CO2 is driving the climate are complete nonsense. Until GCMs can forecast sea surface temperatures, their output is also complete nonsense.
These facts should be obvious, even to the most clueless climate scientist at the US space agency.
