The movement of people based on climate related effects has already begun. Some asylum seekers at the US border are there because of climate stress. Trump’s repugnant border policies may set a precedent for the future management of much larger flows of people, across the globe. It is fair to say that the US is building a concentration camp system. History teaches us that such efforts only deteriorate, and we see this in increasing deaths in custody. This is unacceptable to American ideals. We must view our border circumstances in the context of climate change, and demand a humane and farsighted response.
