A DEAL struck at the UN Climate talks on December 12th shows an international shift in priorities. To hold global warming to between 1.5°C and 2°C, the long-term goal of the agreement, carbon-dioxide emissions must peak before 2030, and decline altogether soon after 2050. The pledges countries submitted as part of the process will lead to no such outcome; five-yearly review cycles may help crank up their ambition at least. But the variety and flexibility of the national pledges facilitated the dealmaking. Big polluters, such as China, came on board because they could decide how and when to curb their emissions.
