Why is it that a large number of Americans cling to the belief that lowering taxes will increase government revenue while simultaneously dismissing out of hand the possibility that global warming could manifest not only warmer summers but also colder winters?

There may be no succinct answer to that question, but I strongly suspect it has something to do with the relatively recent spread in popularity of the mindset that The Market must be the sole arbiter of all human interaction – both with one another and with the world around us – and thus anything that does not permit us to travel down the path of least resistance can be motivated-reasoned out of existence.
