Study Suggests Buried Internet Infrastructure at Risk as Sea Levels Rise (eurekalert.org) 191

Thousands of miles of buried fiber optic cable in densely populated coastal regions of the United States may soon be inundated by rising seas, according to a new study by researchers at the University of Wisconsin-Madison and the University of Oregon. From a report: The study, presented Monday at a meeting of internet network researchers, portrays critical communications infrastructure that could be submerged by rising seas in as soon as 15 years, according to the study's senior author, Paul Barford, a UW-Madison professor of computer science. "Most of the damage that's going to be done in the next 100 years will be done sooner than later," says Barford, an authority on the "physical internet" -- the buried fiber optic cables, data centers, traffic exchanges and termination points that are the nerve centers, arteries and hubs of the vast global information network. "That surprised us. The expectation was that we'd have 50 years to plan for it. We don't have 50 years."

The study, conducted with Barford's former student Ramakrishnan Durairajan, now of the University of Oregon, and Carol Barford, who directs UW-Madison's Center for Sustainability and the Global Environment, is the first assessment of risk of climate change to the internet. It suggests that by the year 2033 more than 4,000 miles of buried fiber optic conduit will be underwater and more than 1,100 traffic hubs will be surrounded by water. The most susceptible U.S. cities, according to the report, are New York, Miami and Seattle, but the effects would not be confined to those areas and would ripple across the internet, says Barford, potentially disrupting global communications.

        All OSP (Outside Plant) fiber optic cable is rated for full immersion. And since measured sea level rise is far less than 0.1 inches per year, in 100 years mean sea level will go up about 10 inches. Assuming it doesnt reverse itself. So move along, ignore the chicken littles.

        I'd like more information on what constitutes "water resistance" and what violates a water resistance claim.

        My guess is anything buried in the ground anyplace other than a desert has some ability to withstand immersion in fresh water nearly indefinitely. A lot of low-lying areas can be prone to periodic flooding or other conditions which would amount to water immersion.

        I'd guess that water pressure is probably a key variable -- "water resistance" probably isn't guaranteed for continuous immersion beyond 5-

Same stuff they bury in the ground and even then it's usually a double conduit. The bigger danger is "shifting" of material in the ground and it breaking the conduit, in turn breaking the cable. We have this problem in Canada with winter freeze/thaw cycles where 4-6"+ movement in the ground is possible. It's why we usually bury at 5.5-6.5' the

    • Stuff underground gets wet already, just in case you didn't know about "rain" and such.

      That sounds like common sense until you actually see how infrastructure is designed. Most stuff underground most definitely does not get wet. Most of this stuff has many services that exist in order to keep it dry while underground.

      A sump pump works great during a storm, not so much for draining an ocean. Also infrastructure typically doesn't cope well at all with flood waters, so even heavy rain is a problem.

    We are fundamentally incapable of long term planning. If we faced a scenario of nothing happening for 50 years and then everything happening at once, we'd be devastated. If things happen throughout the 50 years though, great. It is much easier to handle many little disasters than one big one when you can't plan. It also helps to keep the issue in the public consciousness.

      • Stop making things up. They didn't say we'd all drown, so why do you pretend they did? They actually said, "more than 4,000 miles of buried fiber optic conduit will be underwater." That's not a made up number. They looked at where conduit is buried, how deeply it's buried, and which segments will be underwater in 15 years. And yes, it doesn't take a lot of rise to do that. They were surprised at how much is just a few inches above the current water level. But I guess if you don't like facts, it's eas

        • 45mm is not not "a few inches".

          You are being manipulated and believe nonsense.

          no additional conduit will be submerged if the average ocean depth increases 45mm more.

          waves are higher than 45mm! tides are more than 45mm

          • In 2013, the IPCC estimated the current rate of sea level rise [wikipedia.org] as 3.2 mm/year. If we assume that rate, we get 48 mm in the next 15 years, or about 1.9 inches. But that's an underestimate, because sea level rise is accelerating [nasa.gov]. It has increased substantially in the last 20 years, and that 2013 number is already out of date. The current rate is estimated at 3.4 mm/year. That gives 51 mm or 2 inches. But of course it's still accelerating, so the actual rise over the next 15 years will be a bit more than

            • storm surges last for days and go many inches. look at all the major fiber that fails when that happens.....nope.

  • Relocating Internet infrastructure is a small problem compared to relocating billion of people that live near the sea.

    Even in the US, where there is a lot of inhabited land inside the country, that would cost a lot. Who will pay?

  • "Most of the damage that's going to be done in the next 100 years will be done sooner than later"

    Based on my very rudimentary knowledge of global warming, exponential curves, runaway effects and what have you. That statement is entirely false?

    Also a bit of a scare article. I assume it's implying the 'data sheds' where massive undersea lines terminate are close to the sea (they likely are!) but moving these are probably very very small scale problems in comparison to other issues if the sea rises the dista

    • Global warming is bad, how can we tie it to the internet!!!?

      You are missing an EXTREMELY important point here.

      Almost NOBODY gives a shit about "BILLIONS of OTHER PEOPLE" having issues, but HOLY FUCK WHAT DO YOU MEAN FACEBOOK WILL BE OFFLINE?????? will always get BILLIONS OF VOTERS attention.

  • How long have these supposedly vulnerable cables been in place? The Internet didn't exist before the 1990s. (I know, youngsters, the ARPANet existed earlier, in fact I was using it in the late 1980s. But I'm referring to the modern network that's grown by leaps and bounds.)

    I'd bet these vulnerable cables were put in place in the last couple decades at most, probably 15 years ago. And if they can be placed that quickly, then they can be replaced with newer ones over the next 15 years, a few inches (at l
