U.S. Senators on the Energy & Natural Resources Committee appeared to be at a standstill on global warming proposals May 20. They attempted to make sense of several scenarios--including the Congressional Budget Office--of the economic effects of climate change legislation. The legislation in question is by Senators Joe Lieberman (I-CT) and John Warner (R-VA). This week, the legislation has been ping-ponging around the Capital, gaining traction and perhaps bipartisan support, according to sources. Senators lined up on two sides. Conservatives said they expect investments in limiting greenhouse gases to damage the economy and cause job loss. Liberals maintain that not making the investments will end up destroying both the planet and economy. Both sides found justification in methodology presented.
