Transcript:

Using NOAA's extreme sea level rise estimate, recommended for forecasts involving long-term infrastructure like this, the researchers say that 15 years from now, 4,100 miles of fiber-optic cable could be underwater. And 1,100 internet hubs could be surrounded by water. And remember, our land-based infrastructure isn't waterproof, like transoceanic cables are. "Seawater comes in, and cabling is not meant to work underwater. So signals will be interrupted and dropped. You know, the actual infrastructure itself might deteriorate." The researchers presented the peer reviewed findings at the Applied Networking Research Workshop in Montreal this week. They also write that large internet service providers including AT&T, Century Link and Inteliquent face the greatest risk. So if these predictions play out, internet companies need to harden their networks soon, they say. Or we could lose service during the emergency right when we need it most.
