Climate change could shrink animals, warn scientists

Animals could start shrinking because of global warming, scientists have predicted, after discovering that mammals became ‘dwarfed’ in a similar episode of climate change 50 million years ago.The teeth revealed that during Eocene Thermal Maximum 2, a warming event of around 3C that occurred approximately 53.7 million years ago, the animals shrank in size by 14 per cent.Evidence of mammalian dwarfing during the largest warming event on record, the Paleocene-Eocene Thermal Maximum (PET
