I think the point would be if the climate changes radically on the planet regardless of humans, why do we think these changes are driven by humanity? Perhaps the point is also what is bad about the warming that is being measured? Ie, if change is inevitable, warming rather than cooling could be more beneficial.
We've lived with cooling already. For most of our current Quaternary Ice Age (that we evolved in), it was cooler most of the time.
Ending it, and we're in much less charted waters. We might revert the Earth to its normal hot climate, but this is one where mammals do not thrive, potentially do not even survive, except at the poles.
