Many political leaders have expressed support for strong action on climate change, but what most of them regard as “strong action” will not be enough to get us back below 350 ppm. In some countries, including the United States, there are major political obstacles to taking even modest steps.
虽然许多政治家都赞成对气候变化采取强力行动，但其中大多数人所认为的“强力行动”并不足以把我们带回到350ppm的大气二氧化碳含量水平。而在包括美国在内的一些国家，即使想要采取更为温和的措施都要面对巨大的政治阻力。
