Animals that develop in shallow soils are susceptible to lethal temperatures during heat waves. We found that developing lizards from four populations entered cardiac arrest at temperatures above 46°C. Since temperatures of natural nests can presently exceed this limit, global warming would further reduce recruitment of young.
