Rising sea levels will drown your Western art history course

At least Macchu Picchu is probably safe from sea level rise.


You know how we sometimes like movies in which famous world landmarks are dramatically destroyed? Climate change is about to bring those scenes to a museum near you, albeit with fewer meteors and more meteoric sea level rise.

According to a new report published Wednesday in Environmental Research Letters, everything you love is going to disappear, assuming you are the kind of person who loves old art and history and stuff. The researchers looked at UNESCO World Heritage sites, which, like humans, tend to cluster near the coasts. They simulated flooding the world with an average of 6.6 meters of sea level rise over a couple of centuries. The result was a very soggy situation: About 140 of 720 sites surveyed would be underwater, or at least in the kiddie pool — and that’s without even accounting for storm surge. As one of the researchers encouragingly clarified, these are the low-ball estimates.

Among the soon-to-be-amphibious landmarks are Westminster Abbey and the Tower of London, the Leaning Tower of Pisa (soon with extra leaning!), some old important-sounding German cities, downtown Bruges, and Naples (unless the volcano gets it first). If your tastes incline to the New World instead, you can focus your anxiety of impending loss on the Statue of Liberty and historic Havana. In any case, Atlantis is about to gain a whole bunch of cultural capital:



The purple dots are in trouble even if the thermostat stays where it’s at; everything else up to yellow will drown with just 3 degrees C extra.

3. Are we going to start moving stuff BEFORE it goes under...

... or is every individual event going to be an "unexpected" catastrophe up until the point our civilization has failed and nobody gives a damn because they are too busy looking for food and fighting off bandits or being bandits themselves?

I suspect it will be the later "unexpected" scenario. Every time a surprise until nothing is left.

5. Inclusion of the Statue of Liberty is the kind of reckless hype that helps the deniers.

A reference to the "impending loss (of) the Statue of Liberty" will naturally suggest to most readers that some or all of the statue would be under water. That's preposterous. Liberty Island is flat and low-lying, so if you want to say that the island would be completely flooded, fine; I'm prepared to believe that sea level rise of 6.6 meters would leave no land above the water.

That doesn't mean the loss of the statue, though. Even the Statue of Liberty's sandals are more than 150 feet above the ground, because of the foundation and pedestal.

Maybe the current entrance would be under water. It wouldn't be a big deal to cut another entrance and build a new dock.

I'm not downplaying the climate change crisis. This is just a matter of tactics in how we present it to the public. When we have so many valid arguments, it's foolish to overstate the case so wildly.

http://www.nps.gov/stli/historyculture/statue-statistics.htm

Now, I could NOT find the height of the Walls of Fort Wood (That is the STAR Fort that is the true base of the Stature of Liberty) but Fort Clinton, built at the same time and designed to take the same amount of fire power has walls 20 feet tall. Thus I suspect Fort Wood's wall is only 20 feet tall. The Island itself appears to be less then 6 feet from the water, thus the TOP of the walls of Fort Wood are at least 21 feet above sea level. This is important for the single possible jump in sea level is if the West Antarctic Ice Sheet collapses, and that would rise world wide sea levels about 21 feet. The max is 60 METERs (about 180 feet).

Thus the Statute of Liberty will be above water and so would be its massive base, but the Star Fort it is built on would disappear. When the even larger EAST Antarctic Ice Sheet melts away, the statute would be waist deep, but that is NOT expected for over 100 years for the East Antarctic Ice Sheet is on the HIGHEST overall Continent in the world with little contact between the Ice Sheets in East Antarctica and the oceans (unlike the WEST Antarctic Ice Sheet, while smaller, is based BELOW sea level and thus has direct contact with the ocean and any increase in ocean temperatures).

Thus the Statute if the sea levels raise 65 METERS:
