Global warming increases risk of heat exhaustion in cold-blooded animals

There is a correlation between the geographic distribution of ectotherms or cold-blooded animals and their tolerance to ambient temperature conditions. They can only live where temperatures allow them to grow and reproduce, and the extremes of winter and summer are not too cold or too hot for long periods of time. Animals are injured if the temperature exceeds the threshold they can tolerate. These injuries accumulate over time, ultimately determining whether the species can survive current temperature conditions. The researchers analyzed the temperature sensitivity of 112 species of variegated plants to heat stress. The analysis showed that a 1°C increase in temperature would more than double the thermal damage accumulation rate, and since this is an exponential increase, a 2°C increase in temperature would increase the rate of thermal damage accumulation by more than 4 times, while a 3°C increase in temperature ℃, the speed of damage will increase by more than 8 times. The data suggest that on a global scale, heat injury rates may increase by an average of 700% in ectothermic animals, and by more than 2000% in many environments on land. For aquatic ectotherms, the corresponding figures are 180% and 500%.
