With the arrival of President Obama, the Copenhagen climate talks approach a dramatic climax.
On Thursday Secretary of State Clinton breathed new life into the talks by joining with other developed countries in helping to raise the funding needed to prevent destruction of the world's forests, to adapt to global warming, and to deploy clean technology.
That domino leaned against China, because U.S. cooperation on financing is conditioned on China agreeing to effective monitoring of its important emissions pledges. If Obama can seal this transparency deal with China, then the third domino — levels of emissions reductions sufficient to limit global warming to 2°C (3.6°F) in a binding agreement - may also fall and we will emerge with an historic pact. But each domino must fall.
