Episode notes

This chapter discusses the decoupling of CO2 emissions from economic growth in rich countries and the potential offshoring of emissions. The importance of reducing emissions is emphasized, but the need for active technologies to remove CO2 is acknowledged. The concept of learning curves in relation to cost reductions for renewable energy technologies is also explored.

Our planet and its environment are in bad shape, in all sorts of ways. Those of us who want to improve the situation face a dilemma. On the one hand, we have to be forceful and clear-headed about how the bad the situation actually is. On the other, we don't want to give the impression that things are so bad that it's hopeless. That could -- and, empirically, does -- give people the impression that there's no point in working to make things better. Hannah Ritchie is an environmental researcher at Our World in Data who wants to thread this needle: things are bad, but there are ways we can work to make them better.
