So here's the situation. There is no deal. The world's leaders refused to agree to limit our emissions of warming gases. The most they could agree was to officially "note" the scientific evidence about C – with no roadmap to keep us this side of it. You get a sense of how valuable this "noting" is when you look at the things the conference also "noted": the hard work of the airport security staff, and the quality of the catering in the Bella Centre. It seems impossible, but our leaders really did give the stability of our climate the same status as their praise for Danish sandwiches.
