They predict some species will vanish because they cannot expand into new areas when their native climate heats up.

HELLO!?!?!?! Have not 99.9% of all thr species of plant and animal life that have existed on the Planet Earth become extinct before man existed?

There is also a wobble in the rotational axis of the earth and there is a variation of the rotation of the earth around the sun that is a measurable variable. I think that we don't know nearly enough about the whole system to make any predictions at all. And I detest the canard that man the evil being caused it all.

Prove it. Don't just say it to be so.

A lot of species have gone extinct, that's for sure.

Based on what I've read, ecosystems can adapt to a maximum rate of temperature change of about 2 C per century. That's about the midrange of good estimates for what will happen next century, even from noted skeptics. The Nature article indicates that ecosystem changes are observable due to the warming which has already occurred in the past 100-150 years, most notably the more rapid warming of the last 30 years. That doesn't mean ecosystems will collapse or that major extinctions will ensue (and there are other causes of extinctions that are probably more extensive and also more preventable, such as deforestation).
