Here's a long story by CBS News on Smith Island in the Chesapeake Bay, a tiny island that is shrinking due to erosion and sea level rise. Of course, the islanders are determined to stay.
Erosion eats away up to 12 feet of shoreline a year, according to the Army Corps of Engineers, writesCBS News.
"When I was a little girl they used to say, 'The island's sinking. Now, this weren't yesterday. This has been a long time ago," Marshall said. "Well, fast forward 60-70 years, we're still here."
and
"While Maryland's 2013 offer to buy and demolish Smith Island homes was shot down, it did sound alarms for residents. Watermen and retirees learned how to apply for grants and lobby legislators. They've been successful, receiving more than $43 million for elevating roads, building jetties, restoring buildings and drawing in tourists."
That's for an island of about 200 people, so $200,000 per resident. Add that to the cost of climate change.
A similar island in the Bay, Tangiers Island, is in the same predicament and has the same denial. They want money to build a wall around their island. (What's the point of living on an island if you can't see the ocean?) They're asking for $20-$30 million.
These stories aren't new; they've been coming since decades. Here's an article from 2010.
This is sad and infuriating. Of course the residents want to stay--it's been their beautiful home for decades if not longer. For some it's the only life they know. Their denial is equally sad, and we know it will ultimately be futile, probably sooner than later. And it's infuriating because such situations will become more and more common in the next few decades, and everyone will want to stay, stay, stay until they too give up and, defeated, paddle ashore. What's infuriating is that US politicians simply don't care. Trump thinks the ocean will rise "one-eighth of an inch over the next 400 years" and thinks that's fine because it will create more oceanfront property. There is simply no end to the amount of stupidity that comes out of his mouth, which presumably started in his brain. America elected this dumbass. This is the most shameful election result in the history of the US, so bad that I think it portends the end of the country (which, to be honest, has been coming on for awhile, about since 9/11 and the resulting Gulf War, certainly since the 2008 financial crisis). Or at least a country continuing--faster now--on its way to a shambles of a society. 50% of Americans deserve it. 50% will suffer along with them. Some will presumably drown in their own homes.
I never knew this, though I probably should have. The nautical unit of speed is the knot, which is 1 nautical mile per hour. But it's really 1 arcsec/hr, where the arcmin is taken along the surface of the Earth.
The nautical mile "was defined as the meridian arc length corresponding to one minute (1/60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees). Today the international nautical mile is defined as 1,852 metres (about 6,076 ft; 1.151 mi). The derived unit of speed is the knot, one nautical mile per hour."
I always thought it had something to do with ropes with knots hanging off a ship moving in the water. Maybe that was how they estimated it when traveling, but it wasn't the (somewhat arbitrary) definition as I thought. Good to know.
Here's the event page. 11:02 am Pacific Standard Time, 18:44 UTC.
There were 6.6 and 5.8 precursors in the 15 minutes before this big one.
It was less than 100 km offshore and tsunami warnings have been put up, but the quake(s) were over 2 hours ago so any tsunami would have perhaps hit already (?).
A little too close for comfort. I fear the coming M 9.0 earthquake in the Pacific Northwest will happen on a frigid January morning when I'm in the shower. I just hope I can find my eyeglasses and something to wear.
It sure looks like warming since the last 1970s is starting to accelerate.... But I'm sure that can be explained by someone once sneezing 21 years ago within 10 m of a single weather station in Greenland.
