Yeah, I think it's more than that now (6 years later). What I'm hearing from the climate science community is that we have 2C baked-in (no pun intended), and given that we aren't doing close to enough to stop the trend, we'll hit at least 2.2-2.3C within the century.

As I said, I've already realized that we aren't going to do anything. And as you said, the US will survive it (most likely). Though there may have to be migrations, coastal cities almost certainly will have to be walled-off from the sea, the US Navy is already moving one of their bases inland in anticipation (I think it was in Virginia?). It's not gonna be cheap. Building walls around Miami, L.A., NYC, etc, will be very expensive.

The mass refugee problem from other nations will be a challenge. If LM is screaming about migrants now...just wait. I think 1/3 of Bangladesh will be underwater (at least at high tide) by the end of the century.

It's gonna be a mess, and our grandchildren will curse us.
