I am a concerned Scientist.

I do not believe that economic growth is more important than sustaining our global environment.

I do believe that Alberta's continued development of the tar sands is deeply and morally wrong.

I am

The National Energy Board (NEB) gives the Northern Gateway a conditional go ahead ... BUT what were those probability calculations? ... and where are our morals?

For doubters: has global warming just stopped? Well maybe not quite yet! Watch this (old news) and then this (recent news)!
