We are obliged by the proposed new Canadian laws against spreading climate disinformation on the internet to tell you that this graph is upward sloping. And that Alaska is one of those states that, being near the Arctic, is especially hard hit by climate change along with all the others. So its sea levels must be rising rapidly. And as you can see, they are. From 1980 to the present the sea surface at Juneau has risen by nearly 15.5 mm per year. And to make it even scarier, it’s rising down, because “nearly” in this case is a euphemism for “minus”. Where will it all end?
Well, at CDN we like to calculate how long it would take for the sea to go up by one meter in the various spots on our “CDN by the sea” tour at whatever rate it is currently rising there. And in Juneau the answer is just minus 65 years, plus however long it takes to build a time machine that can run backwards. So if you plan to go to the water’s edge in Juneau, you probably won’t want flip flops because it’s not all that warm, and anyway a good pair of running shoes might come in handier.
