I think what they are saying is the climate did not change across the K-T boundary until about 40 million years ago. The asteroid came, the dinosaurs went, but the climate stayed warmer for 25 million more years...

All the stuff I've seen on TV [and you know how accurate that is] postulates a long period of global cooling, lack of sunlight, etc. after the asteroid hit.

This would , by my standards, indicate a fairly massive shift in climate. Oh well, to each his own.

Long period being relative. Long for us (several thousand years). Short for geologic time.
