I've seen a few graphs in my day, and they generally don't do that. Sure, it could happen, but it almost certainly won't. :(

That said, the US and China both making steady progress is very good, but then again, a Trump presidency certainly might see some of that reverse.

I think the big questions is: how do we get Russia and India to curb their emissions? If India follows China's per capita curve, but with a 20 year delay, it'll be disastrous. They're going to need significant help to continue industrializing without seeing a huge rise in emissions.

I don't think I'd have seen this coming even 5 years ago, but China really might be positioned to be a global climate leader.
