global warming could make us shorter.

The warming climate could make us shorter over time, suggest new research that found that mammals in the past had responded to extreme global warming by shrinking in size. while this mammalian dwarfism has previously been linked to the largest of the warming events, the new research has found that this evolutionary process can happen in smaller such events as well. the findings could help shape an understanding of underlying effects of current human caused climate change. we know that during the largest of these hyper-thermals , known as the Paleocene thermal maximum or PETM, temperature rose an estimated 9 to 14 degrees Fahrenheit and some mammals shrank by 30 percent over time, so we wanted to see if this pattern repeated during other warming events.
