Dear Journalists,
1. "If we do not change course by 2020, we risk missing the point where we can avoid runaway climate change" @AntonioGuterres
*self-reinforcing feedbacks causing a lot of continued warming even with emissions reductions
2. It's June 2020
This is the context.

'Runaway' is a very tricky word in the context of climate change as it is used in different ways.
This conversation sums things up quite nicely, I think:

I was told to delete this tweet because the article says 'runaway' means that at 2C (by ~2035) warming to 3C- 5C becomes inevitable. Looking at Arctic, forest and other feedbacks this looks plausible to me (particularly 3C) but I wouldn't state it as fact.
Keep in mind Arctic feedbacks (albedo, permafrost etc) could lead to a huge amount of additional warming within decades (>1°C?), but we just don't know. Some warming looks inevitable to me, but how much?
