Need for swift action

I am a strong proponent of a carbon tax to address the climate-related costs of using fossil fuels [“Use carbon tax to fix transportation,” Opinion, Jan. 3]. I also recognize that carbon taxes are at least somewhat regressive (though to what degree is debatable,) and have favored a revenue-neutral carbon tax as a way to internalize the external costs of fossil fuel use.

But the point that Yoram Bauman and Ian Siadak makes is well-taken: We all have a reality problem and the sooner we wake up to it and seek a comprehensive solution, the better chance we have of averting an even larger climate crisis than is already upon us.
