Don Mac

I have a B.Sc. and M.Sc. in Earth Sciences. I was a research geologist for 15 years, a climate change/environmental policy advisor in government for about 15 years, a manager of energy technologies for 5 years, and taught at a small university in Alberta, Canada for about 8 years. I still teaching the odd course from time to time.
