Climate change could cause cold-blooded animals’ thermal tolerance to shrink

ScienceDaily: Cold-blooded animals can tolerate body temperatures only a few degrees above their normal high temperatures before they overheat, which could be a problem as the planet itself warms, according to San Francisco State University researchers. Ectotherms such as fish, reptiles and insects can stretch their body's tolerance of high and low temperatures a little bit at each extreme, but that stretch, or plasticity, is relatively small, the scientists found.
