It advocates a “World War II” style mobilization, of the sort that existed back when the federal government took over almost half the entire economy.
I understand that’s not what you support, but people do support massive efforts like this to combat climate change. My point is simply that when you say climate change will have “untold cost” you make it impossible to understand why the programs you support might be worth it, while a World War II-style mobilization would do more harm than good.
