Roy Thompson, FRSE, is Professor Emeritus and Senior Honorary Professorial Fellow, and a former Professor of Environmental Geophysics at the University of Edinburgh, and a friend of my cycling buddy Shane. In his video, available on the University of Edinburgh Social Responsibility and Sustainability page, he opines on the results of Paris. While the Paris accords speak of limiting warming to 1.5C, his model shows that at our current pace we should expect warming of 8C by the end of the century. Experts are divided, but even if all the parties to Paris deliver on their current pledges it will cut the 8C by only 0.1C to 0.5C. Time to redouble the campaign to leave it in the ground.
