More than 10,000 Environmental Protection Agency employees have made a call to Congress to take action on global warming. Jesse Russell reports:

It all started with a petition that began circulating within between staff at the EPA. The petition called on Congress to take immediate action to help stop global warming and called for an end to censorship by the current administration against scientists and specialists who research topics related to climate change and air pollution. The petition was released by the Public Employees for Environmental Responsibility. In addition to the more than 10,000 employees the petition was signed by the presidents of 22 locals in the five unions that represent EPA workers: The American Federation of Government Employees, the Engineers and Scientists of California, the National Association of Government Employees, the National Association of Independent Labor, and the National Treasury Employees Union. Yesterday also marked the day the U.S. Supreme Court was hearing arguments in a case brought by states and environmental groups demanding that the administration begin regulating greenhouse gases.
