The human enhanced pace of dangerous climate change is a reality and Canada has a valuable role to play in global efforts to reverse that pace.  Arguably that role is to illustrate by concrete action that a modern, advanced economy can materially reduce its carbon footprint without tanking its economic prospects.  It is the absence of proof on this point that is a major drag on global efforts to take more than token steps to address the existential threat currently posed by climate change.

Gwyn Morgan expresses the position that it vis essentially pointless for Canada to address climate change while too many of those convinced by the evidence supporting the climate change thesis are not prepared to develop sound concrete and workable models for transition to a dramatic reduction in net carbon emissions.

A well designed carbon tax regime can be an effective cornerstone for an effective middle course that would constitute the valuable Canadian contribution I describe.
