We are the change we have been waiting for, at some later date to be determined:

Less than a month before negotiators will meet in Copenhagen with the lofty goal of crafting a deal to curb global greenhouse gas emissions, the Obama administration is considering endorsing a limited short-term climate pact and deferring more ambitious action until next year.
The scaled-back strategy is driven largely by the realities of domestic politics: The administration is hampered in making an international deal because Congress has not passed climate legislation. So any global pact would be postponed until next year when it would be constrained by whatever domestic climate legislation Congress enacts.
Backing an interim agreement — which would fall far short of what many European and developing nations envisioned when President Obama took office — would be an attempt to keep the U.N.-sponsored talks from being viewed a failure, say administration and congressional officials.
They emphasize that the trimmed-back approach should not be viewed as a withdrawal of U.S. commitment, but rather as a first step: “An interim, operational deal is not meant to be seen as a substitute for a real agreement,” Todd Stern, the U.S. special envoy on climate change, said in an interview. “It’s meant to be seen as substantive building blocks to a full, legal agreement, and perhaps the best chance of getting such an agreement.”
