Climate change can exacerbate the drivers of migration, other drivers of migration, whether that's food or water stress. And so that's a big problem. Major migration flows, refugee flows, can have a significant regional and international security impact. But there's also, and those are some of the new risks we need to really be worried about. But climate change also impacts the existing geopolitical environment as we know it. In the Arctic, obviously, it's creating a new ocean. In the South China Sea, we see fish stocks moving north, fishing fleets moving into contested waters. So you have tension between China and its neighbors, and that brings in the US as well. So we have these sort of traditional geostrategic environments which are unstable, becoming more unstable. And that's something that climate change is going to potentially create more of. So we should be worried about it.
