And the compromises continue:
If changes in the public mood and the party alignment of the U.S. Senate have stalled healthcare legislation, they may have thrown the highly anticipated climate bill under a bus.
President Obama has backed down too. On Tuesday, he signaled that cap-and-trade could go the way of healthcare reform's "public option," saying it could be removed from the climate bill. That would eliminate the market mechanism for pricing greenhouse gas pollution -- and without setting such a carbon price, other measures under consideration, such as a national renewable energy standard, won't go far enough to significantly slow global warming.
