With Halloween fast approaching, the Senate appears to be all tricks and no treats. Topping the list is the Joe Lieberman (D-Conn.) and John McCain (R-Ariz.) proposal to cap carbon dioxide emissions. The “Climate Stewardship Act,” which was open for debate in the Senate on Thursday, October 29, seeks to address concerns about global warming. The problem is, the science behind global warming theory is far from complete, and the scientific community continues to identify uncertainties and problems with existing theories about global warming. On the other hand, the costs of measures such as the Lieberman-McCain proposal and the Kyoto Protocol are not inconsequential; passing such proposals is sure to be a trick, not a treat, for all consumers.
