Abstract Climate change causes warmer and more variable temperatures globally, impacting physiological rates function in ectothermic animals. Acclimation of can help maintain function. However, it is unresolved how variance changes with temperature despite its potential ecological evolutionary importance. We developed new effect sizes that capture both the mean variation across (based on coefficient, ) used them to test acclimation acute thermal responses vary aquatic terrestrial ectotherms using meta‐analysis (>1900 effects from 226 species). Comparing magnitude side‐by‐side provides unique opportunities for evaluating importance plasticity selection under climate change. show increases at higher temperatures, but depends habitat. Freshwater marine are capable have greatest increase variance. In contrast, reduced abilities smaller rate. Simulations suggest these patterns may result differences among‐individual breadth optima performance curves habitats. Our results highlight greater vulnerability because a lack capacity limited provide less raw material adaptation. Considering therefore important understanding will impact populations.
