As the Earth's climate warms, living things will experience increasingly frequent and intense heat waves. But we should not rely too much on evolution for species to acclimatize to it: according to a study published in February in Nature Communications and co-signed by Pierre Calosi, researcher in biology at UQAR, tolerance to heat is much less adaptable than cold hardiness.
