Hmm, I've visited a huge excavation of mammoths near Rapid City, South Dakota, but I don't remember a strong theme of how the big guys went extinct.   That particular location was speculated as a watering hole that trapped the beasts.       You wouldn't think normal animal behavior would 'pile on' in a search for water, but I suppose if desperate, those things could happen.

I have zero doubt that humans worldwide are contributing to an unnaturally fast rise in temperature.  No doubt.   If we refuse to accept the facts, then we can do nothing to alter the course of the degradation we have today.   

I do find using Mastodon's a big stretch if the authors goal is to gain support for those acknowledging current global warming.

Is that what bothered you Motley, or, was it something else?    People can read the same article and get very different meanings!
