Summary

Story summary

Researchers at Trinity College Dublin identified a universal thermal performance curve (UTPC) that governs how all life forms respond to temperature changes.
The UTPC shows performance rises with temperature to an optimum, then declines sharply, risking physiological failure or death.
The study analyzed over 2,500 thermal performance curves across diverse species, and scientists will assess whether any deviation is possible as global temperatures continue to rise.
