Perhaps the "prof" should step into the real world for an hour or two.  Money is finite.  The demand for government investments far outstrips supply.  There is a near zero benefit to the planet's climate which will result from Canada's investment - if major polluters increase or do nothing to reduce GHG output.  So the trade-off becomes, spend a few billion dollars knowing in advance nothing will materialize or spend money to reduce homelessness, research on effective ways to reduce GHG's or mitigate the impact of climate change, feed the world's starving - or countless other meaningful options.  You could burn hundred dollar bills to stay warm, but why would you?  Canada should undertake that our GHG emissions will not increase as a percentage of the world's output.  More than that is a huge waste.  With H-D's so far in the clouds the view must be wonderful.  One of the many joys of tenure no doubt!
