So what is at stake? There are two issues to address. To remedy this, the paper’s researchers, led by Daniel Mitchell and others at Oxford University, called for a dedicated program of research to help inform what they described as “arguably one of the most momentous to be made in the coming decade.” And they are on the case, with their own dedicated website and a major conference planned at Oxford in the fall. As a commentary published online in Nature Climate Change last week warned, there is “a paucity of scientific analysis” about the consequences of pursuing a 1.5-degree target. They want the job done by 2018, in time to inform renewed talks on toughening emissions targets beyond those agreed upon in Paris.īut the truth is that scientists are only now getting out of the blocks to address what a 1.5-degree world would look like, because until recently it sounded like a political and technological impossibility. In Paris, delegates called on the U.N.’s Intergovernmental Panel on Climate Change (IPCC) to report on the implications of a 1.5 target. So would it be worth it? And is it even remotely achievable? Given we are already at one degree above pre-industrial levels, halting at 1.5 would look to be at least twice as hard as the two-degree option.
