Let’s imagine the most optimistic climate change scenario for a century from now, without going completely bonkers. To do that, let’s first split up greenhouse gas emissions (CO₂-equivalent or “CO₂e”) into non-residual and residual emissions. The latter are emissions that are difficult or impossible to (fully) eliminate due to technological or other limitations. In our scenario, non-residual emissions — that is, emissions that we can actually reduce with current technology and without disastrous socio-economic impacts — continue to grow a little bit for a while (as they do in reality), but the curve starts bending down soon (which is a...
