Researchers in Canada have predicted that if the world ’s remaining fossil fuels were to be burned , global temperatures would rise by 2020 by 2300 . Temperatures in the Arctic would rise by 17C and the tropical Pacific could see a fourfold increase in rainfall . Meanwhile , rainfall in Africa , the Amazon , southern Africa and the Mediterranean could halve . Central Asia and tropical Africa could also witness decreased rainfall . The scientists had access to more complex estimates than those used to provide previous estimates . They concluded that climate change could be “ considerably more profound ” than already predicted and could result in extreme damage to “ ecosystems , human health , agriculture , economies and other sectors ” .
Researchers in Canada have estimated that if the world’s remaining fossil fuels were to be burned, global temperatures would rise by 8C by 2300. Temperatures in the Arctic would increase by 17C and the tropical Pacific could see a fourfold increase in rainfall. Meanwhile, rainfall in Australia, the Amazon, southern Africa and the Mediterranean could halve. Central Asia and North Africa could also witness decreased rainfall. The researchers had access to more complex models than those used to provide previous estimates. They concluded that climate change could be “considerably more profound” than already predicted and could result in extreme damage to “ecosystems, human health, agriculture, economies and other sectors”.
