Animals can adapt to increasingly frequent cold snaps

There is substantial genetic variation in nature for both long-term seasonal acclimation and short-term acclimation associated with rapid extreme weather events, a new study shows. While much of the emphasis regarding climate change is on overall warming, increased frequency of extreme weather events is also a critical concern. As fall and spring temperatures rise, animals will increasingly have to deal with rapid changes from warm conditions to dangerously cold temperatures as weather fronts sweep through.
