It remains far from clear, however, whether the shift in rhetoric and policy will move the planet any closer to embracing the best response. Both McCain and Obama could leave future generations lumbered with the costs of major cuts in carbon emissions – without major cuts in temperatures.
但是，在措辞和政策上的变化是否会使这个星球更近一步的迎来最佳的反响，这还远远不清楚。麦凯恩和奥巴马都可以让后人受到重大碳减排－而对气温升高没有多大遏制－的措施的代价的拖累。
