Watched 60 minutes on I belive CNBC last night. They had a piece on coal and its hugh impact to the CO2 level when burned by electrical power plants. The rub was the main player in the piece was the CEO of Duke energy. He was saying that something needs to be done quickly to clean up the coal burning, and with all the plants we have it could take up to 40 years to clean it up. He is much in favor of cleaning it up and wants to do it as quickly as he can. Of course when they talked to the NASA climatologist he said that is way to late and we should stop right now any new building of coal power plants. That if we don't act right now in 20 years it will be to late and we will not have the climate that we have enjoyed for thousands of years.
In the mean time it said China and India are producing more CO2 from their plants than the US. Also China is building something like a new coal power plant each week, and they don't scrub the emissions.
The piece did show an impressive coal train comming in with about 100 train cars of coal for delivery. The CEO of duke said the plant receives two train loads a day. That did look like alot of coal because that train was plenty long with coal cars.
