In Paris 2015, world governments agreed to keep the increase in mean global temperature to well below 2C above pre-industrial levels and preferably under 1.5C.
Six years later, how can the world meet those goals? How far have we come since 2015 and what is the scale of the task ahead? What are the specific targets we need to hit, and which are the crucial sectors that need decarbonising? And with only days to go before COP26 begins, what do the world’s governments need to do to ensure the Paris Agreement remains attainable?
Five senior scientists with expertise in climate change and GHG emissions laid out their views and took journalists’ questions.
