Here is a video report from Copenhagen where President Obama says a "Meaningful Agreement" has been reached at the end of the "Climate Change Summit" that took place there.
However, no firm commitments were made by key parties, in particular from China or India.
In reality, the "Meaningful Agreement" is nothing more than a fig leaf to give the appearance that something was really accomplished when it was not. Obama arrived at the end of the conference as if he could float in there and work magic. But this was a miserable failure, and a total waste of time, and the White House knows it.
