It seems to me that this question might be testable by looking at whether deserts moved north in
previous warm eras.

In
previous work published in 2013 in Nature Geoscience, Pogge von Strandmann and a different team of colleagues used geochemical simulations to determine that an increase in weathering during an
era of
warming 93.5 million years ago known as ocean anoxic event 2 may have led to sequestering of carbon and cooling of the planet.
* As there is more snow / ice to melt than in
previous cold periods presumably even a rise to the levels of
previous warm periods will cause more melting than in
previous eras.
Other than if there is a sudden slow down or reversal in temperatures, which I am not expecting for many years if
previous extended
eras of
warming are repeated.
For example, we saw in the
previous section, that the temperature records show a period of substantial
warming followed by a period of substantial cooling up to the satellite
era.
He also demonstrates the trivial effects of the
warming that is predicted and discounts their claimed negative effects, noting that scientific developments mean we are far less hostage to climate shifts than in
previous eras.»
Mann's research was thorough and interesting, and like Manley's work with CET, and Hansen's with global temperature, was a considerable feat of research and re-interpretation of existing knowledge, which until then had accepted considerable variability, with
previous episodes of
warming exceeding those in the modern
era.
