We’ve reached a sad milestone: Climate change has claimed its first mammal species. Scientists have been warning us that a large percentage of species will face extinction thanks to manmade global warming, and the future is unfortunately here.According to The Guardian, climate change’s first mammal victim was an adorable rodent known as the Bramble Cay melomys. Sometimes called a mosaic-tailed rat, the melomys was named after Bramble Cay, an Australian island close to Papua New Guinea, that was the only known home for the species.
