Let China clean their own back yard first.

Does that mean our air conditioners will be stunted again?
The hubris to believe that we can control the climate or that outlawing one compound will make any difference whatsoever...
And I notice this too was done on the sly, like everything else.

Finally, having put in place a credible plan to meet its international climate goals, then the United States can negotiate a global climate treaty in 2015.

He can negotiate it (however unlikely that may be) but Obama will never be able to get the Senate to ratify a global climate treaty in 2015. Remember, it takes a 2/3 majority.

A 1987 agreement banned those, giving rise to HFCs as a replacement, which don’t cause an ozone hole but do heat up the atmosphere a lot.

From Wikipedia:

Regulation and DuPont

In 1978 the United States banned the use of CFCs such as Freon in aerosol cans, the beginning of a long series of regulatory actions against their use. The critical DuPont manufacturing patent for Freon ("Process for Fluorinating Halohydrocarbons", U.S. Patent #3258500) was set to expire in 1979. In conjunction with other industrial peers DuPont sponsored efforts such as the "Alliance for Responsible CFC Policy" to question anti-CFC science, but in a turnabout in 1986 DuPont, with new patents in hand, publicly condemned CFCs.[9] DuPont representatives appeared before the Montreal Protocol urging that CFCs be banned worldwide and stated that their new HCFCs would meet the worldwide demand for refrigerants.[9]

Let's see, 1986 plus 34 years (issuance term plus renewal) is 2020. Any bets on whether DuPont has a replacement for HFC?

CFC’s and HFC’s are by far worse than CO2 but the article is wrong. China is the worst polluter.
