Hi Rich; more research, this is china after all, still says coal production down in 2014 and 2015.
They have canceled building coal plants both in 2016 and 2017 and in 2017 put a moratorium on building. Air quality is very bad, people are protesting, 750,000 deaths a year. It will be years before emissions will drop, California ocean pH is down to 7.4 in places, that from average of 8.1. Like the Richter scale the pH is exponential.
I'm not sure if anybody really knows what will happen in our oceans, or what is happening but killing a level in a food pyramid, especially near the bottom can't be good for levels above. 
King Salmon returns have been a problem in the Copper and Yukon, there are coral reefs , . being killed by heat worldwide. ocean food chain failure would really impact Alaska.
China's response's to problems are not encumbered by a two party system but there is plenty of corruption and foot dragging, meanwhile ice is melting ocean rising hard to be optimistic.
