Intergovernmental agreements were never going to fix anything. Sensible measures are being proven to to be effective, including price signals at a national level, and are how things will be best handled.
Flattening global emissions are a good thing but there is a connection between emissions and economic activity. With some major nations dropping economically, there cannot be complacency.
International agreements saved the ozone layer, so it can fix some things.. However, they way global warming has been handled has been pretty bad. It is hardly surprising that quite a few countries do not like to have binding limits that put formal limits on their economic activities, it would be better if CO2-emissions were internationally taxed to achieve the same effect without formally limiting the emissions from any country.
