I am increasingly pessimistic about the long term future of the US. What are the chances that we will still be one country in a generation or two? Trump might have poured gasoline on the fire, but the federal government has been in decline for years. Congress is completely dysfunctional. The filibuster prevents the senate from doing anything. The president is at war with the civil servants and more interested in grift, punishing percieved enemies and erecting monuments to himself instead actually leading.
Addressing climate change requires massive changes and a lot of political courage. There is none.
There is no legal mechanism left that could correct course at this point. You would need to have a constitutional amendment to drastically reshape government and that's DOA. All that's left is snow decline and eventual dissolution
