Reuters: Climate change risk threatens 18 U.S. military sites: study
Rising sea levels due to hurricanes and tidal flooding intensified by climate change will put military bases along the U.S. East Coast and Gulf Coast at risk, according to a report released on Wednesday.
Nonprofit group the Union of Concerned Scientists analyzed 18 military installations that represent more than 120 coastal bases nationwide to weigh the impact of climate change on their operations.
Faster rates of sea level rises in the second half of this century could mean that tidal flooding will become a daily occurrence for some installations, pushing useable land needed for military training and testing into tidal zones, said the report titled "The U.S. Military on the Front Lines of Rising Seas."

ReplyDeleteRay Toll, a retired naval oceanographer, says the "majority of [the naval base], if not all of it" is at risk of flooding "because it's so low and it's flat."
ReplyDeleteThe Norfolk-Hampton Roads area in Virginia is home to the largest naval operation in the world. This area is particularly vulnerable because the land is sinking as sea levels are rising. Planning for that is both a national security concern and a topic of discussion among the area's business owners.
WNU Editor,
ReplyDeleteSince 1994, NASA has recorded a 9.01 cm rise in sea levels, 19.8 cm rise in sea levels since 1870.
While some low lying islands have disappeared from sea level rise, unless your City is only an inch or two above sea level, you arn't going to see a city "drowning" from the direct effects of sea level rise for quite a while.
It's the indirect effects that are causeing problems right now.

Drain's run on a 1":7' ratio. Any slope greater than that and the waste is left behind in the drain as the water runs off. Any slope less than that, and the waste settles out as the water doesn't have enough velocity to carry it away. If you have a 1" rise of water, covering the drains exit into the sewer system, long enough, then you get a "shock hydraulic dam effect", water and waste then backs up in your drain, until you flush your toilet and the contents bubble up into your basement through the floor drain.
Storm drain systems are vulnerable to the same effect, which is why now, in low lying cities like Tampa and Norfolk, rain falls not a problem in the past, now cause massive flooding.
The short term "fix" is watertight seawalls and massive high speed pumping stations to evacuate the water. For a City like Norfolk, is only a multibillion dollar project that should have been started years ago. For a City like Tampa, on porous limestone, there is no solution other than relocate.
Mountain retreats in Quebec are safe. Rest easy.
