"Cold blood won't save lizards from rising temperatures"
[
Despite many claims about climate change wreaking havoc on biodiversity, there
are very few experimentally-validated models that can accurately explain recent
extinctions and project future extinctions based on rising temperatures.
However, a study in last week's Science conclusively links extinctions of
Sceloporus lizard species to climate change and forecasts a gloomy future for
many other lizard species around the world.
