Since China is the country where you can't see three feet in front of you and everyone needs a breath mask to survive, they should be "a champion of the agreement and as a world leader."

"Standing on the international stage" does not require one to be leading every parade down the street.

 Since the primary role the Paris Accord had for the United States was to provide taxpayer money,   I'm perfectly comfortable to watch all those others spend their taxpayer's money instead of mine.

If Europe and China will now have the "advantage in the burgeoning field of renewable energy", the US will just have to muddle along.

"Hydroelectric power is currently the largest producer of renewable power in the U.S. It produced around 6.14% of the nation's total electricity in 2015 which was 45.71% of the total renewable power in the U.S.

"Wind power provides 4.1% of the nation's electricity."

Solar power currently produces 0.59% of US renewable energy and 0.08% of total energy.
