The largest and most important climate change conference in history opened this morning in Copenhagen, Denmark. Representatives from 192 countries -- governmental, inter-governmental, and non-governmental organizations -- and thousands of journalists arrived by bicycle, train, bio-fueled limo, and plane to witness the 15th Annual Conference of the Parties to the United Nations Framework Convention on Climate Change.

We will blog consistently over the 11 days of the conference and keep you apprised of progress and live coverage from some of our colleagues and partners via Twitter and the Seal the Deal in Copenhagen channel on Live Earth Video.
