On August 2, 2007 Senator Lieberman and John Warner (R-VA) introduced a framework for Lieberman-Warner America’s Climate Security Act of 2007. The proposal, which we refer to here as the “Lieberman-Warner” bill, calls for the United States to make substantial cuts in greenhouse gas (GHG) emissions below current levels by 2050. Such GHG emissions cuts will contribute to global efforts aimed at reducing atmospheric concentrations of GHG and mitigating harm to our climate system. The most recent assessment report of the Intergovernmental Panel on Climate Change provides a scientific basis for the world’s countries to take strong action to mitigate the threats of climate change.
