First off, I wonder exactly what insights Joe Biden can provide about "what to expect from the Trump administration". I don't think he even knows what's going on in the Obama Administration.

Second is Mckenna's  comment about the cost of Canada's carbon reduction plan.... "While the measures are costly, "the cost of inaction on climate change are much greater"."   What exactly are the costs of inaction and, in the alternative, are there cheaper alternatives that involve less money, less government and less regulation?
