Lots of science deniers on here today, lets use facts and science to combat their hate. 

In terms of the oil sands, the efforts to control per bbl carbon has resulted in substantial cuts. "In 2014, oil sands GHG emissions per barrel were 31 percent below 1990 levels. It is expected emissions per barrel will continue to decline over the coming years." - http://www.nrcan.gc.ca/energy/publications/18731 

We also know that the oil sands contributes .1% to global ghg emissions, so it is in reality a negligible contributor to global warming. http://www.nrcan.gc.ca/energy/publications/18731 

These are indisputable facts, this is science. Not screeching eco-fascist terrorism designed to attack infrastructure, instill fear and suit obtuse and irrational agendas. The oil sands are not the problem, they are the shiny hot button that attracts those of less intellectual capacity, who are looking for easy targets.
