At the end of the month the world will gather in Paris, France for the next round of climate change talks. In advance of the talks, the Financial Times put together this model of how emissions reductions will help—or not—get climate change under control. The piece is two-fold. The first is a ten-step narrative that showcases the tool’s split of the time series into short-, medium-, and long-term impacts and how those work in the best and worst case scenarios. But it then allows the user to jump right on in and create their own scenarios.
