The inconvenient truth here is that America's environmental activists refuse to acknowledge that they now have a clear public policy
pathway available to them for achieving the steep
emission reductions they desire, a
pathway they can travel reasonably quickly and reasonably successfully
without undue hindrance from climate science skeptics.
Even if switching to natural gas in the short term reduces the US carbon footprint somewhat, it is still not sufficient by itself to put the US on an
emissions reduction pathway consistent with its ethical obligations
without other policy interventions including putting a price on carbon or rapid ramp up of renewable energy.
