Think Progress Warns of Sea Level Rise 2000 Years from Today. Again.

You can’t criticize Think Progress for not recycling. Here’s some familiar-sounding alarmism:

East Antarctic Melting Could Raise Sea Levels By 10 To 13 Feet, Study Finds

A region of East Antarctica is more vulnerable than previously thought to a massive thaw that could result in world sea levels rising for thousands of years, a study found Sunday.

The study, published in the journal Nature Climate Change, looked at the 600-mile Wilkes Basin in East Antarctica, which, if it melted, has enough ice to raise sea levels by 10 to 13 feet. Researchers found that the region was vulnerable to melting because it’s held in place by a small “ice plug” that may melt over the next few centuries, meaning East Antarctica could “become a large contributor to future sea-level rise on timescales beyond a century,” according to the article.

“East Antarctica’s Wilkes Basin is like a bottle on a slant. Once uncorked, it empties out,” Matthias Mengel, lead author of the study, said in a statement.

Which is a lot like this from March:

Sea Level Rise Threatens The Statue Of Liberty And Hundreds Of Other Cultural Heritage Sites

Almost 200 cultural heritage sites, including the Statue of Liberty and the Sydney Opera House, could be compromised if global warming reaches 3 degrees above pre-industrial levels, a new report in Environmental Research Letters shows.

The research released Tuesday from Austria and Germany used both sea-level estimates for the next 2000 years and high-resolution topography data to compute which of the more than 700 listed UNESCO World Heritage sites would be affected by sea-level rise at different levels of sustained future warming. The report found that if warming reaches 3 degrees Celsius, sea level would rise six feet in the next 2,000 years, and 170 of those sites would be drowned.

Oh, and by the way, we’ll probably be more worried about an ice age 2,000 years from now than Antarctica’s melting ice. Via MIT’s Technology Review:

But even that warming will not stave off the eventual return of huge glaciers, because ice ages last for millennia and fossil fuels will not.In about 300 years, all available fossil fuels may well have been consumed.Over the following centuries, excess carbon dioxide will naturally dissolve into the oceans or get trapped by the formation of carbonate minerals. Such processes won’t be offset by the industrial emissions we see today, and atmospheric carbon dioxide will slowly decline toward preindustrial levels. In about 2,000 years, when the types of planetary motions that can induce polar cooling start to coincide again, the current warming trend will be a distant memory.

I guess in 2,000 years, after humans have moved to Mars to avoid the ice age, Think Progress will bitch about how anthropogenic factors are messing up the terraformed atmosphere.
