Scientists told to plan for bigger climate crises

Scientists are overlooking the impacts and risks posed by an increase in global temperatures of more than 4°C, the United Nations' climate change conference has heard.

World leaders are gathered in Marrakech, Morocco, for the UN’s COP22 climate change conference. The summit is taking place between 7 and 18 November, shortly after the Paris Agreement on climate change entered into force on 4 November.

All governments that have ratified the Paris Agreement are obliged to keep global warming to no more than 2°C above pre-industrial levels.
