Climate issues dominated the headlines through the fall of 2009. In December, delegates from around the world gathered in Copenhagen in hopes of striking agreement to limit greenhouse gas emissions. Swirling around that meeting of world leaders, bureaucrats, environmental advocates and those looking to make a buck on the climate change debate are new allegations challenging the integrity of the underlying science. Emails leaked by a hacker or whistle blower from the Climatic Research Unit (CRU) in the United Kingdom raise grave concerns about the data used to justify regulations advanced by the Environmental Protection Agency (EPA) and legislation before the U.S. Senate. Picking up where their colleagues in the House of Representatives left off, the Senate pushed ahead with legislation to cap greenhouse gas emissions and create a trading regime, only to see the effort stall as the costs of the proposal became clearer and attention shifted to the equally intractable problem of health care reform.
