While attending a meeting of prominent climate sceptics during the U.N. Climate Conference in Copenhagen in December (an anti-COP15, if you will), I listened to each of the speakers put forward their theory on why conventional evidence on the primary causes of climate change should be dismissed as, for lack of a better phrase, complete hokum.

Uncertainty about the future cost of emissions allowances for greenhouse gases is one of the biggest obstacles to winning consent for a cap and trade or cap and refund programme in the U.S. Congress. To have any realistic prospect of passing emissions legislation, lawmakers must find a way to reduce it.
Proponents argue a trading programme would ensure emissions reductions are achieved in the most cost-effective manner. They point to the success of the Environmental Protection Agency (EPA)'s Acid Rain Program in cutting sulphur dioxide (SO2) emissions much more quickly and at a fraction of the expected costs during the 1990s.
As hopes for reaching a binding agreement to cut greenhouse gas emissions at the Copenhagen summit die, climate negotiators could learn useful lessons on how to structure the negotiations from the multiple rounds of trade talks within the GATT/WTO framework.
