Global Warming Could Shrink Humans

If case of prehistoric horse applies.

Global warming causes more extreme weather, rising oceans, melting ice caps, droughts, and animal extinction. Oh, and it might shrink you, too. A group of American scientists published a study Thursday in the journal Science that showed the prehistoric horse—in fact, the first horse—called Sifrhippus, shrank from an average of 12 pounds to about eight and a half some 56 million years ago, when the climate warmed up over thousands of years. Sifrhippus is much smaller than the modern horse—it's about the size of a cat. Scientists have known that mammals tend to shrink with global warming, but the study offered some of the first specific data on the phenomenon.
