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

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 new research. As a result, the animals will see their ‘thermal safety margins’ shrink as global temperatures rise. Shifts in behavior or evolutionary changes might be the best hope for these animals to adapt to climate change, the researchers note. —> Read More
