Were Dinosaurs: (Largely) Killed Off By Rapid Climate Change?

The BBC's, David Attenborough-presented Dinosaurs: The Final Day has received popular acclaim (https://www.theguardian.com/tv-and-radio/2022/apr/15/dinosaurs-the-final-day-with-david-attenborough-review-a-thrilling-slice-of-time-travelling-detective-work). Dinosaurs: The Final Day covered what might well have happened, in one area of North Dakota, on a day around 66 million years ago. Then, an asteroid larger than Everest asteroid, struck the Yucatan peninsula in distant Mexico. The power released has been estimated to have been equivalent to a billion simultaneous Hiroshima atom bombs. The feature-length programme was a broadly convincing account. The animated sequences were, however, a little too prone to poetic licence, for my personal taste. We should remember a number of things about this 'final day'. Firstly, this was a mass extinction event, with dinosaurs only the most notable victims. Many other species were also relatively quickly wiped from the fossil record. In addition, some close dinosaur relatives, e.g. the birds, survived the event and subsequently flourished. Secondly, this might well have been 'the final day' for organisms living in that area of Dakota. It is, however, likely that dinosaurs (and other soon-to-be-extinct organisms) in more distant locations, persisted longer (we could be talking about days here). Thirdly, it seems highly likely that asteroid impact-induced rapid climate change actually caused the, worldwide, mass extinction event. Fourthly, the 'stupid' dinosaurs (we can't even be certain this was the case), didn't cause their own extinction. Our species of the supposedly more intelligent Mammals (Homo sapiens means 'wise man'), might be well on the way to generating our own mass extinction event. We don't even require an asteroid!
