First CCS will speed depletion. If a world coal peak without CCS was expected by 2025 it will come sooner if extra coal has to shovelled into the furnaces to power the scrubbing, compression and pumping process

This could be mitigated by achieving 20-30% electricity consumption reductions. Say coal burn per kWh increases by 20-30% but electricity consumption reduces by the same amount then coal tonnage burnt remains the same.

'peak coal' is tendentious, although perhaps an article of faith amongst some here.

Global Warming is real, and now.

If we've run out of coal in the 22nd century, then we'll find an alternative source of energy.

The problem is going to be getting through the 21st century without cooking the planet.

Only a fool would take the mid point of the IPCC case, and not worry about the right hand tail of the distribution.

What chance do we need of a 6 degree C rise in temperature to panic, now? 1%? 0.5%
