for both these accelerations, no scientific discipline knows a precedent or comparable parallel caused by natural climate fluctuations.

Not actually true, Sky.
Carboniferous period saw the most diverse range of plant and animal life (albeit somewhat less complex than todays), and the period finished in an extremely quick fashion at the end of the period.
Interesting to note, that C02 levels were roughly 3000ppm as opposed to the measly 385 or so of today, and yet the earth supported more and more diverse life than now.
hmmm
