possible relationship between tectonic rift length and atmospheric CO2 concentration over the last 200 million years

This argument is so stupid and it also makes me pretty angry.

The switches between glaciated icehouse to ice-free greenhouse conditions were processes that took millions of years in the past and were modulated by tectonics (i.e. the fragmentation or formation of supercontinents) and the large changes in CO2 concentration that went with them. For example, the change from peak-Cenozoic conditions to ice sheets on both hemisphere took something 47 million years.

You're welcome to believe that natural variation of climate was just about to undo all that in a few centuries (starting at the same time as human emissions of GHGs accelerate, by wild coincidence I'm sure), but that has absolutely nothing to do with the real world.
