I wouldn't worry. Once the ice caps extend down to the tropics, polar bears will eat all the lizards, thus solving the problem once and for all.

Hmm, I sense a cunning plan at work here

Global perils of dirt, glaciers and lizardocalypse overblown, say boffins ? The Register

A trio of new studies out this week have undermined three of the basic ideas underpinning the belief that the world is facing imminent doom as a result of human carbon emissions and perhaps-associated global warming in past decades. It would seem that the menaces of a runaway feedback loop driven by carbon belching from overheated Arctic dirt, surging sea levels powered by melting mountain glaciers, and imminent extinction for cuddly tropical lizards are all a lot less likely than scientists had previously thought.
