Genau diese Entwicklung habe ich seit mehr als einem Jahr vorausgesagt: President-elect Barack Obama’s administration is prepared to embrace mandatory limits on greenhouse gas emissions in the United States but will push through Congress a new international climate treaty only if China and other big emitters join in a “global solution,” Sen. John Kerry warned at the latest round of climate talks Thursday in Poland. Unless China and other powerhouses in the developing world agree to quickly follow the U.S. toward large-scale emissions cuts, “there’s no way for us to get from here to there” in terms of holding climate change to less than catastrophic levels, he said at a news conference.
