Nonsense. What makes your copy and paste suspicious is it's confidence and certainty as to cause and effect. Science is replete with uncertainty. A quick look finds that ....

However it appears much more likely that simple microbes, not the Siberian eruptions, caused the mess 252 million years ago. Do I know that for sure? Nope. Nobody does.
