选一段：
First, all major economies must put forward decisive national actions that will reduce their emissions, and begin to turn the corner on climate change. I’m pleased that many of us have already done so, and I’m confident that America will fulfill the commitments that we have made: cutting our emissions in the range of 17 percent by 2020, and by more than 80 percent by 2050 in line with final legislation.

可国内新闻网站高挂：奥巴马气候大会发言，未就减排做出承诺。
