Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

"Unpalatable." A good description.

It becomes somewhat more palatable, though, if it's a bridge to a better answer. I expect that projections of ongoing, large CO2 emissions will turn out to be pessimistic because falling costs for solar-energy based electric power and fuels will provide an attractive alternative to burning stuff. At that point, political pressure should be very effective at forcing a switchover.

If solar energy gets cheap enough, as I expect, then we can start thinking about removing surplus CO2 from the atmosphere. Extracting it would require a lot of energy, but not completely overwhelming -- a fraction of human power consumption in 2006 over a fraction of a century.
