National leaders are meeting at the United Nations in New York today, to discuss the climate change negotiations. Talks will continue at the G-20 meeting in Pittsburgh later in the week. But hopes look very bleak for progress sufficient to produce at Copenhagen in December a successor treaty to the Kyoto Protocol. The biggest roadblock is the familiar game of “After you, Alphonse.” The United States will not accept quantitative emission targets unless China, India and other developing countries do the same, at the same time. But the developing countries will not cut their emissions below the Business as Usual path (BAU) unless the rich countries go first.
