This is the first time-limited giant problem we’ve ever faced (unless you count, say, World War II, which also couldn’t be postponed very long). At this point, having delayed action for so long, the easy baby steps are no longer helpful. A small price on carbon won’t get us as far as it would have a decade or two ago.
In the end, the problem isn’t getting a bill through Congress. The problem is global warming. And it may be useful to begin any discussion of strategy with that in mind.
