Researchers who studied the fate of six species of 'megafauna' over the past 50,000 years found that climate change and habitat loss were involved in many of the extinctions, with humans playing a part in some cases but not others.

I was watching a show about this the other day and they were saying that climate change was unlikely to have killed the giant armadillo. It survived for more than a million years through multiple ice ages and the wide climatic swings between the. I turn around the next day and I see a "climatologist" declaring that animals are all going to become extinct because of global warming.

Whst do we call it when an existing scientific theory is unable to explain phenemna that we know exists?

It means that the present theory is wrong.
