Could you just give us the executive summary please -- in a paragraph? I don't think you really need to, or I don't need to anyway, spend an hour teasing out a couple ideas.

Weak stuff? It's the one thing in place that's been signed by 195 countries and ratified by 147 countries. Will the reduction pledges get us to 2 degree celsius? Not according to this NY Times graphic: https://www.nytimes.com/interactive/2017…®ion=top-news&WT.nav=top-news&_r=0

but it's a building block, a place to start, the only game in town, etc. Work with it, get early victories and improve on it, rather than pontificate from the sidelines about it being weak stuff

Right?
The ACA is weak stuff, except where it isn't. The idea is to get the framework in place, then build upon it.

@3
In any case it doesn't provide much of grounds for disagreement
