ANU boffins say it wasn’t climate change that did for the megafauna

By johnboy - 1 July 2013 48

ANU is having a go at debunking the idea that the mass extinction of large animals in the Australian mainland 50,000 years ago was caused by random climate variations.

Humans with pointy sticks and hunting fires come sharply into the frame although the boffins don’t go that far.

What’s Your opinion?

Oh dear. Crash goes another climate change myth.

I’d be interested in any source you can cite that blamed megafauna extinctions on climate change?

It’s been a topic of debate for quite a while.

And I bet you this bit of work is not the final word on the subject. For a start it’s based on a single sediment core and you have to infer when the various species became extinct by noting when they stop appearing in the fossil record.

Probably anther case where the press release version is far more strident than the evidence would support. If the journal paper wasn’t behind a pay-wall we might be able to see what the scientists were telling other scientists.

Don’t tell the elephants

That’s why I qualified my statement with the word “most”, smarty-pants :p

I was under the impression that our atmosphere lost the oxygen required to allow the existence of most giant animals, but I may have been completely mislead when I heard that.

Human beings hunt easily-hunted fauna to extinction. Nothing’s new in the world…
Endangered 140-year-old Orange Roughy with your chips anyone? Get it from the fish shop in the Canberra Centre.

Excellent book the Future Eaters.

I’m pretty sure I had already read that in The Future Eaters?

Megafauna tasted good.

Pointy sticks and sharply,ah penetrating puns indeed, although the massive fires may have been triggered by multiple lightning strikes..
