World: As the ice caps get smaller, so do Earth’s plants and animals. Wait, what?

  • 45% of species are shrinking over time, a new study says source
  • » Blame climate change, the study says: It’s like scary, natural shrink ray. But, yep, animals such as fish, reptiles, birds and mammals are all smaller than generations previous — apparently a difference of one degree celsius is enough to make things smaller. The researchers, who published their study in the journal Nature Climate Change, warn to not jump to conclusions, though: “We do not yet know the exact mechanisms involved, or why some organisms are getting smaller while others are unaffected,” the authors of the study, based at the National University of Singapore, said in an interview. “Until we understand more, we could be risking negative consequences that we can’t yet quantify.”
