Ahh, I think I expressed myself badly. I didn't mean that temperatures could return, period (although on second reading, my text does convey that). I meant that things couldn't be reversed as in a movie being played backwards, returning things to their original state.
I think we're actually in agreement, but talking past each other due to my poor initial phrasing.

Even if aliens took all of the "excess" CO2 out of the atmosphere tomorrow, manipulated the climate so it was always 1969 weather-wise (because that's the definition of perfection), and gave us an endless supply of dilithium crystals, things 10 years from now would be different than they are today.
Change always happens. The relevant question is good vs bad. (I don't see how one can assume that new species will necessarily be bad.)
