Fallout from climate change is escalating at such a rapid pace the world now faces a “narrowing window” to adapt to a warming planet if it does not reduce the emission of greenhouse gases, a United Nations report warns. Released Monday, the latest Intergovernmental Panel on Climate Change (IPCC) report brought together 270 scientists from 67 countries to assess the impacts climate change is having on humans and the ecosystems they rely on. “Today's IPCC report is an atlas of human suffering and a damning indictment of failed climate leadership,” said United Nations Secretary-General António Guterres.
