I don't understand the relevance of determining who is rich or poor among countries just so curbing man-made gas emissions can be started. Why can't just countries unite and start moving as changes in climate have already caused catastrophic damages. There are just too many disputes going on while the problem is getting worse by the minute. America has spent billions of money in the war so why can't it do the same to solve climate change?
China claims that the US releases most of the heat-trapping gases. Fine. But this was in the 1950's. Times have changed and now China's share of global emissions exceeds 25 percent, while the U.S. share has fallen toward 20 percent. But still China argues that the US is unwilling to live up to their obligations to cut carbon emissions.
China is the world's second largest economy but is still considered a developing country under UN classification. This means that developed countries are obliged to give them money in their fight against climate change. Isn't China lucky?
