Coal's future is safe, but climate's not so certain

Does coal have a future? Climate change protesters and coal traders alike say it's a daft question, but agreement ends there.

For protesters, the shiny black lumps of fossilized wood and plants are contributing to drastic climate change. For traders, coal is an energy no-brainer which offers a ray of hope for 1.6 billion people living without electricity.

They're probably both right.
