Rate of sea-level rise 'steeper'

Source: BBC

Their reassessment of tide gauge data from 1900-1990 found that the world's seas went up more slowly than earlier estimates - by about 1.2mm per year.

But this makes the 3mm per year tracked by satellites since 1990 a much bigger trend change as a consequence.

It could mean some projections for future rises having to be revisited.

"Our estimates from 1993 to 2010 agree with [the prior] estimates from modern tide gauges and satellite altimetry, within the bounds of uncertainty. But that means that the acceleration into the last two decades is far worse than previously thought," said Dr Carling Hay from Harvard University in Cambridge, Massachusetts.

"This new acceleration is about 25% higher than previous estimates," she told BBC News.

3. King Tides morphing into Emperor Tides? Buh-bye Miami, Norfolk, Savannah

and coastal points in between. The question is which people living in these expanding flood plains are pragmatic enough to sell their homes there now while there is still a real estate market of clueless new retirees, and which people will sentimentally & stubbornly wait to be flooded out. Cause if you can't get a mortgage and flood insurance on these properties, and that day has already arrived in some areas, there is no market for them. If you want to stay there, lease a property or get a houseboat.

A national report released recently by the Union of Concerned Scientists highlights these nuisance flooding events in U.S. coastal communities and warns that more and worse coastal floods are coming in future decades.

“Several decades ago, flooding at high tide was simply not a problem,” said Melanie Fitzpatrick, report co-author and climate scientist at the Union of Concerned Scientists. “Today, when the tide is extra high, people find themselves splashing through downtown Miami, Norfolk and Annapolis on sunny days and dealing with flooded roads in Atlantic City, Savannah and the coast of New Hampshire.”


In Norfolk, evidence of climate change is in the streets at high tide
NORFOLK — At high tide on the small inlet next to Norfolk’s most prestigious art museum, the water lapped at the very top of the concrete sea wall that has held it back for 100 years. It seeped up through storm drains, puddled on the promenade and spread, half a foot deep, across the street, where a sign read, “Road Closed.”

The sun was shining, but all around the inlet people were bracing for more serious flooding. The Chrysler Museum of Art had just completed a $24 million renovation that emptied the basement, now accessible only by ladder, and lifted the heating and air-conditioning systems to the top floor. A local accounting firm stood behind a homemade barricade of stanchions and detachable flaps rigged to keep the water out. And the congregation of the Unitarian Church of Norfolk was looking to evacuate.

“We don’t like being the poster child for climate change,” said the Rev. Jennifer Slade, who added that the building, with its carved-wood sanctuary and soaring flood-insurance rates, would soon be on the market for the first time in four decades. “I don’t know many churches that have to put the tide chart on their Web site” so people know whether they can get to church.

On May 6, the Obama administration released the third National Climate Assessment, and President Obama proclaimed climate change no longer a theory; its effects, he said, are already here. This came as no surprise in Norfolk, where normal tides have risen 11 / 2 feet over the past century and the sea is rising faster than anywhere else on the East Coast.

Check out these pictures of street flooding in Norfolk - the owners can write off those cars. Come to think of it, in addition to being unable to get mortgages/homeowners' insurance, auto insurance will also be hard to get/incredibly expensive in those areas.

4. Sadly, this will continue as people wake up

And realize that climate change is real. The terrible news is that even every country changed their behavior tomorrow, this ocean rise may eventually slow but I fear we cannot stop it. It's too late, but we should do everything in our power to try.

5. A lot of people live in the 'flood plains' can't afford to move or afford insurance. Fema will not

Fema will not sell pre-insurance either to those who live in flood plains. The price of home insurance for those who live in flood plains is already sky high.

That means the insurance corps, the federal agencies all know those low lay areas are doomed the next big hurricane.

Even if you can't afford insurance or the Fema pre-insurance, get free quotes...it's a very good 'free' way to tell if you're going to flood in future.

7. The conservative hive will doubt...

... whatever they're told to doubt. It's the evil scum like the Kochs, Inhofe, and other Neocon thought-fuhrers who KNOW they're lying through their teeth and endangering the lives of millions, who must be held accountable for what amounts to a crime against humanity. All of humanity IS threatened by their actions - or inactions - after all. But, like all sociopaths, they simply don't give a shit. Whatever serves their malign, greedy purposes is all that matters.

The Brits will bet on anything. I wonder if anyone's taking odds on whether it'll be the West Antarctic ice sheet, or Greenland's that does the Big Splash first? My money's on Greenland. Any takers?
