At least they never had no planks of wood telling us cow farts are destroying the air, and changing the weather, lol.
“If they were unable to migrate south they could have been wiped out. Climate change is now very much on the agenda in trying to determine how the dinosaurs became extinct.
“We now believe that they died out gradually and it is very possible that this could have been caused by a series of climatic changes.''

British researchers claim that a sudden plummeting in the sea temperature of 16F (9C) more than 137 million years ago was the first step towards their eventual road to extinction.

70 million years though? This is just to large a timescale for any climate change theory to hold any water with regards to killing off the dinosaurs.

Climate scientists have less credibility than used car salesmen. When people start telling me what happened to the planet in terms of millions of years and they can't even tell me what happened 5 years ago without distorting and resorting to fake science I sort of tune out.

In the future when the world is so over populated that we have exhausted the meat supplies we learn the secret of time travelling and go back in time and hunt the dinosaurs out of existence!
I don't believe that for one minute, but I have read the theory, sorry no links etc.
The timeline in the OP just doesn't hold up, I think i'll stick with the comet theory for now.
