Nearly 80 percent of the world's poorest, or about 900 million people, are directly exposed to climate hazards exacerbated by global warming, bearing a "double and deeply unequal burden," the United Nations warned Friday.
"No one is immune to the increasingly frequent and stronger climate change effects like droughts, floods, heat waves, and air pollution, but it's the poorest among us who are facing the harshest impact," Haoliang Xu, acting administrator of the United Nations Development Programme, told AFP in a statement.
