I agree and I'd hope to see the information tweaked based on latest research, which is what they're doing. Hope other spots with similar plaques and signs follow suit. Just so skeptics have less to argue with, not just entering the park and going 'Ha, see, signs in this place are wrong so, clearly, climate science is wrong.' Yes, true, our estimates are changing on the regular but that's better than just pretending like the problem doesn't exist or hoping it's small.

Even if they change signs to read 'will melt in 2050', that's still terrifying. So I do hope they put up new data soon.
