China, Climate, Coal

I've been following this week's climate talks (between President Obama and Chinese President Xi Jinping) with interest.  Mr. Xi said his country would curtail carbon dioxide emissions so that they would peak “around 2030.” Mr. Obama pledged that the United States would cut emissions by at least 26 percent from 2005 levels by 2025 — a goal in line with targets he promised in a 2009 United Nations accord. This is better than nothing, but still sounds like too little and too late....
