"Climate change is always followed by mass extinction."

DonExodus2 of Youtube fame gave me this answer with succinct brevity.

Here was what I asked him:

If you accept Darwinian evolution, AND you accept climate change, wouldn’t you expect ecosystems to collapse, since they evolved in a different climate? Isn’t it inevitable that species that are selected to survive in a particular environment aren’t going to survive when that environment is altered faster than they can genetically adapt?

He has a collection of interesting and informative videos here:

And here, my quest has ended after much searching, I have FINALLY found scientific corroboration for vast phenological change due to anthropogenic global warming, thanks to a Dr. Camilla Parmesan at the University of Texas:

THANK YOU DR. PARMESAN FOR THIS GEM!

"7. Although evolutionary responses have been documented (mainly in insects), there is little evidence that observed genetic shifts are of the type or magnitude to prevent predicted species extinctions."

Here is a typical large old pin oak with bare branches, a sweet white flower, and a tragic variegated dogwood that cost quite a bit of money, with it's leaves pathetically drooping even after days of rain. Damn.
