On a per capita basis, the U.S. contribution to this historical stock is more than 18 times that of India, for example. And while wealthy nations like the U.S. ask today’s big developing-country emitters like India to reduce emissions now, those developing countries rightfully demand that their rich neighbors do more, given the wealth they’ve gained from years of burning fossil fuels unchecked. The result is a finger-pointing contest that leaves the world neither doing enough now to deal with the realities of climate change, nor planning to do so in the future.
