The previous discussion is missing the "reply to" Cap and trade will worsen the recession = economic down turn, not only in the USA but many other countries which depend on the USA to buy the stuff they export to the USA. There will be less investor money to build big wind turbines and install them. Vehicle makers will slow down their plans to produce CNG vehicles. The continuing bad ecconomy will reduce the carbon dioxide emissions more in 2009 than Cap and trade will reduce emissions in many years. USA may become a third world country, (in days) if Cap and trade passes.
If we are at the start of a new ice age, reducing carbon dioxide entering our atmosphere will hasten the crushing of Northern cities, as the mile tall ice cap moves South. Does any one know any good results likely to follow Cap and Trade? Neil
