Um, Canada has ⅔ of _all of the coastline in the world_.

@mattdm Is that before or after the effects of projected sea level rise?

That is now.
My guess, though, is that the fraction will increase, because a lot of the world total is islands.

I expect that as you measure with higher precision, Canada and Norway go even higher up the list.

Yeah I am really just wildly guessing here.
Indonesia is losing hundreds of actual whole islands already (sea level rise _and_ sinking land). But I think maybe Canada will still have a really jagged coat, just a different one (including outcrops that didn't used to be islands but then are).
