Thirty five years after the transition from global cooling panic to global warming panic, There is no unique, broadly accepted GOAL, no PLAN to achieve a goal and no TIMELINE. There is no definition of what a carbon tax would be expected to accomplish, though the economic pain is a given. There is not even agreement on how large a carbon tax should be, though there is much interest in how the revenues might be spent. There is certainly no broad discussion of the fact that a US carbon tax would not solve the "problem".
"You've got to be careful, if you don't know where you're going, because you might end up someplace else.", Yogi Berra, American philosopher
