Coral Davenport of the NYT provides some of the basics of the Paris climate change agreement. This includes an effort to cut greenhouse gas emissions by half to avoid a situation in which atmospheric temperatures rise by 2 degrees Celsius or 3.6 degree Fahrenheit.  The earlier effort to negotiate an accord failed in 2009 in Copenhagen. This time all 186 countries were asked to signup with the USA and China, the No. 1 and No. 2 polluters and India leading the way.

How did this happen now? As Davenport points out there are scientific studies. But this is not the primary reason China is shifting.Davenport fails to emphasize the health concerns and pollution concerns that motivated China to shift away from coal.

The other big polluter India is shifting because it is learning from China's experience. Davenport mentions the resistance to the scientific evidence in the Republican party. As a result it is already clear that it lacks support in Congress and under a future Republican administration. In a fashion similar to healthcare, president Obama failed to create a consensus before proceeding in the hope that this would be better than waiting. However American industry is already moving away from coal as documented in Links- "The Trump executive order on coal and the continuing shift to natural gas." Utilities in the U.S. are making the shift away from coal because of the economics and planning ahead as governments can change every four years. ...

This follows the decision by the IMF to add the renminbi as one of the leading currencies with the dollar, pound, yen and euro.
