But is it enough? And how would we know if it were? : The U.S. federal government is proposing to spend a sum of money that starts with a “T” on an infrastructure bill, and much of that money (two trillion dollars) is aimed at fighting the climate crisis. That is remarkable, and not just when you consider that we’re only seventy-five days out from an Administration that didn’t believe climate change was real. In my lifetime, we’ve spent sums like that mainly on highly dangerous infrastructure—aircraft carriers, fighter jets, nuclear weapons—and the wars in which they were used.
