Climate change driving 'cost-of-living' squeeze in lizards

Desert lizards are facing a 'cost-of-living' squeeze as global temperatures continue to rise, a new study finds. For a lizard, the 'cost-of-living' is tightly linked to its body temperature, which dictates both how much food it needs and whether it can go outside to feed. Desert lizards are especially challenged because food is sparse, and it is often too hot to forage.
