What killed the dinosaurs?

Recommended Posts

 

I know what you are thinking: these silly scientists; first they tell us that an asteroid killed the dinosaurs, now they tell us that it is not true. So, how can we believe them when they tell us that humans are causing global warming? 

On this, I have to tell you something: science is a mighty truth-seeking juggernaut. Yes, individual scientists are not immune from mistakes, political biases, and human failures, but, on the whole, science manages to filter away bad ideas and keep the good ones. The case of the extinction of the dinosaurs is a beautiful example of how well the mechanism works.

As you will read in the article below, dinosaurs, it seems, went away not with an asteroidal bang, but with a volcanic whisper. They were killed over several tens of thousands of years by the global warming created by the emission of gases from the giant basaltic eruption known as the "Deccan Traps", today located on the Indian subcontinent. The discussion is far from being settled and many scientists still favor the impact theory (e.g. Peter Ward and Joe Kirschvink in their recent book "A new history of life"). Personally, I am no specialist in these matters but, if I did my homework well (and I think I did), my impression is that the data overwhelmingly favor the volcanic hypothesis over the asteroidal one.

And, as far as I know, the Dinosaurs went extinct as a result of both the asteroid impact and the Deccan Traps eruption?? :cc_confused:
