Does global warming cause animals to shrink?

A study of copepods found that the growth rates of the tiny marine crustaceans is highly sensitive to temperature, with implications for the entire food chain.

A study of tiny marine crustaceans called copepods suggests that rising global temperatures can result in smaller animals, at least cold-blooded ones. .
Melting ice, outbreaks of disease, more intense storms and more forest fires are just some of the effects scientists say will accompany human-caused climate change. Scientists are now exploring another, perhaps more surprising, potential effect: Shrinking animals.
A new study has examined how warmer temperatures can result in smaller individuals within a species.
This relationship between size and temperature change only holds for cold-blooded animals,
which rely on external sources, such as sunlight, to warm themselves. Scientists don't understand why this relationship exists. But it's important because size influences an individual's reproductive success, as smaller animals tend to have fewer offspring, and its role in a food chain, among other things.Read More
