Flooding of Coast, Caused by Global Warming, Has Already Begun http://nyti.ms/2c9EXZQ

 

I think global warming deniers should build homes there. Put your money where your mouth is, otherwise shut your piehole.

 

The coastal lands, which are timeless, will never change because nothing ever changes.

 

A thousand years ago to a thousand years from now.

Waterfront homes in Key West start at a million. They are building more, not less.

For a little while.....your kind of insanity might prevail.....but then reality is coming along fairly quickly to bitch-slap the blind rightwingnut imbeciles who are still building or buying homes there......good news for you, nutty retard...you might finally be able to afford a ocean front house when they are selling for ten bucks.

Sure for a while. I can't predict the future but I CAN predict the gamble wealthy people are making on owning real estate on the coasts.

 

...and they're not deterred

1900 Galveston hurricane - Wikipedia, the free encyclopedia

The Great Galveston Hurricane was a Category 4 storm, with winds of up to 145 miles per hour, which made landfall on September 8, 1900, in Galveston, Texas, in the United States, leaving about 8,000 dead. It was the deadliest hurricane in US history.

So what, moron?

 

Why do you imagine that pointing to some strong storm a hundred or so years ago has any significance to the current situation? Why do you imagine that only hurricanes that strike the USA should count?

 

The 1970 Bhola cyclone is the deadliest tropical cyclone on record, killing more than 300,000 people[123] and potentially as many as 1 million[124] after striking the densely populated Ganges Delta region of Bangladesh on November 13, 1970. Its powerful storm surge was responsible for the high death toll.[123] Elsewhere, Typhoon Nina killed nearly 100,000 in China in 1975.[126] Tropical Storm Thelma in November 1991 killed thousands in the Philippines,[128] although the strongest typhoon to ever make landfall on record was Typhoon Haiyan on November 2013, causing widespread devastation in the Eastern Visayas and killing at least 6,300 people in that country alone. In 1982, the unnamed tropical depression that eventually became Hurricane Paul killed around 1,000 people in Central America.[129]

Are they? It will only take a few military trained snipers to even the score. Every Marine is a sharp shooter. There are a lot of scout snipers out there. While I don't condone such things if it happens good people will be grinning from to ear. Robes Pierre knew what to do about the filthy rich criminal elite. I think it is time to grease up the guillotine.

La is disappearing the quickest...thousands of acres daily are disappearing

 

The upside is that a lot of Florida will be submerged. I hope they secede first. When they cry for help we can just say FUCK YOU CONS!

This shit has been going on for 100s of thousands of years. Same as earthquakes. Same as tornadoes. The Earth is and has been dynamic since day one.

One other thing; Gore & people like him are as crazy as bed bugs.

I will vote for Trump; and if he does win, it will be comforting for me to know that my vote contributed to greasing America's slide into Hell.

 

Human caused global warming is intensifying the largest storms. That fact is not diminished by the fact that the Earth has always had some strong storms on occasion in the past.

 

Former Vice-President Gore and the world scientific community are quite sane and live in the real world. You, on the other hand, are totally bugfuck insane and live in some deranged rightwingnut fantasy world.

This isn't some back-in-the-day, old-folks-exaggerating type of story. As Billiot knows all too well, the marsh of Louisiana's fragile coast is disappearing at a mind-blowing rate.
A football field of land, on average, falls into the Gulf each hour.
That bears repeating: A football field of land, per hour, gone.
So, that's 24 football fields.
At 1.3 acres per field, that's 31.2 w/o cheerleaders ... per day.
So lets hype and spin and be petrified at the thought a thirteen year old is on this forum.

That is a figure for Louisiana's hourly land loss that has been quoted for the last decade or more, as if there have been no changes in the rate since it was first calculated.

 

Actually back before 2008, scientists had already cited a higher figure.

The rate figure is undoubtably higher now, as sea levels are higher than they were a decade ago. The rate will continue to climb as Greenland and Antarctica ice sheets continue to melt at accelerating rates, and it will abruptly soar when one of the ice sheets collapses and disintegrates.

 

Abrupt Sea Level Rise Looms As Increasingly Realistic Threat

Ninety-nine percent of the planet's freshwater ice is locked up in the Antarctic and Greenland ice caps. Now, a growing number of studies are raising the possibility that as those ice sheets melt, sea levels could rise by six feet this century, and far higher in the next, flooding many of the world's populated coastal areas.

Last month in Greenland, more than a tenth of the ice sheets surface was melting in the unseasonably warm spring sun, smashing 2010s record for a thaw so early in the year. In the Antarctic, warm water licking at the base of the continents western ice sheet is, in effect, dissolving the cork that holds back the flow of glaciers into the sea; ice is now seeping like wine from a toppled bottle.

 

The planets polar ice is melting fast, and recent satellite data, models, and fieldwork have left scientists sobered by the speed of the sea level rise we should expect over the coming decades. Although researchers have long projected that the planets biggest ice sheets and glaciers will wilt in the face of rising temperatures, estimates of the rate of that change keep going up. When the Intergovernmental Panel on Climate Change (IPCC) put out its last report in 2013, the consensus was for under a meter (3.3 feet) of sea level rise by 2100. In just the last few years, at least one modeling study suggests we might need to double that.

 

Eric Rignot at the University of California, Irvine says that study underscores the possible speed of ice sheet melt and collapse. "Once these processes start to kick in," he says, "they're very fast."

 

The Earth has seen sudden climate change and rapid sea level rise before. At the end of the planets last glaciation, starting about 14,000 years ago, sea levels rose by more than 13 feet a century as the huge North American ice sheet melted. Greenland is losing some 200 billion tons of ice each year. That rate doubled from the 1900s to the 2000s.But researchers are hesitant about predicting similarly rapid climate shifts in our future given the huge stakes involved: The rapid collapse of todays polar ice sheets would erase densely populated parts of our coastlines.

 

"Today, were struggling with 3 millimeters [0.1 inch] per year [of sea level rise]," says Robert DeConto at the University of Massachusetts-Amherst, co-author of one of the more sobering new studies. "We're talking about centimeters per year. That's really tough. At that point your engineering can't keep up; you're down to demolition and rebuilding."

 

Antarctica and Greenland hold the overwhelming majority of the worlds ice: Ninety percent of the planets freshwater ice is locked up in Antarcticas ice cap and nine percent in Greenlands. Today, the ice sheet that's inarguably melting fastest is Greenland. That giant block of ice, which has the potential to raise global sea levels by 23 feet if it melts in its entirety, is losing some 200 billion tons of ice each year. That rate has doubled from the 1900s to the 2000s.

 

"We are seeing changes in Greenland in all four corners, even in the far north," says Rignot. Many of the outlet glaciers that flow down fjords into the sea, which were "on the fence" about retreating or advancing over the past decade, are now "starting to fall apart," he says.

And they're moving fast. "The flow speeds we talk about today would have been jaw-dropping in the 1990s," says Ted Scambos of the University of Colorado's National Snow and Ice Data Center. Greenland's Jakobshavn Glacier dumped ice into the sea at the astonishing rate of 150 feet per day in the summer of 2012. The most dramatic action in Greenland is simply from surface melting, as temperatures there and across the Arctic have soared in the last four decades. In 2012, Greenland lost a record 562 billion tons of ice as more than 90 percent of its surface melted in the summer sun.

 

Many questions remain about the physics of Greenland's ice loss, such as whether meltwater gets soaked up by a 'sponge' of snow and ice, or trickles down to lubricate the base of the ice sheet and speed its seaward movement. Most modeling work has been about how Greenlands melt tracks rising air temperatures; far less is known about how warming waters might eat away at the edges of its ice sheet. Rignot is part of a team now launching the Oceans Melting Greenland project (with the intentionally punny acronym OMG) to investigate that. These uncertainties make Rignot think that estimates of Greenlands melt -- contributing as much as 9 inches of global sea level rise by 2100, according to the 2013 IPCC report -- have been far too conservative. Assuming that the Greenland ice sheet's demise "will be slow is wishful thinking," Rignot says.

 

But most scientists say there shouldn't be too many serious surprises about the physics governing Greenland's ice loss. Although the ice sheet can be expected to steadily melt in the face of rising temperatures, Greenland's ice cap shouldnt rapidly collapse, because most of its ice sits safely on rock far above sea level. "Greenland is more predictable and straightforward," says DeConto.

 

For fear of rapid, runaway collapse, the research community turns its eyes south.

 

Antarctica is, for now, losing ice more slowly than Greenland. The latest data from the GRACE project -- twin satellites that measure mass using gravity data -- say Antarctica is losing about 92 billion tons of ice per year, with that rate having doubled from 2003 to 2014. The sizeable western half of Antarctica holds some of the fastest-warming areas on the planet.But Antarctica is vast -- 1.5 times the size of the United States, with ice three miles thick in places -- and holds enough ice to raise global sea levels by roughly 200 feet.

 

The larger, eastern half lies mostly above sea level and remains very cold; researchers have typically considered its ice stable, though even that view is beginning to change. The sizeable western half of the Antarctic, by contrast, has its base lying below sea level, and holds some of the fastest warming areas on the planet. "You look at West Antarctica and you think: How come its still there?" says Rignot.

 

Warming ocean water licking at the underside of the floating edges of the Western Antarctic Ice Sheet is eating away at the line where the ice rests on solid rock. Much of the bedrock of the Antarctic slopes downward toward the center of the continent, so as the invading water flows downhill it seeps further and further inland, causing ever-larger chunks of glaciers to flow faster into the sea. This so-called "grounding line" has been eroding inland rapidly, in some parts of West Antarctica at rates of miles per year. In 2014, satellite radar images revealed just how vulnerable five massive glaciers flowing into the Admundsen Sea are from this effect. And a 2015 paper showed that the same thing is happening more slowly to Totten Glacier, one of the biggest glaciers in the east.

 

Such dramatic processes have been the bane of Antarctic modeling and the reason why scientists have been loathe to put a number on sea level contributions from a melting southern continent. Then in March came a report in Nature that some say represents a step change in our ability to do that. DeConto and David Pollard of Pennsylvania State University put into their ice sheet model two basic phenomena: meltwater trickling down to lubricate glacier flow, and giant walls of ice (created when the ends of glaciers snap off) simply collapsing under their own weight. These new modeling parameters gave DeConto and Pollard a better understanding of past sea level rise events. For the Pliocene era 3 million years ago, for example -- when seas were dozens of feet higher than today -- older models estimated that a partially melting Antarctic added about 23 feet to global sea level rise. The new model increased Antarcticas contribution to sea level rise during the Pliocene to 56 feet.

Turning their model to the future, DeConto and Pollard project more than three feet of sea level rise from Antarctica alone by 2100 -- assuming growing greenhouse gas emissions that boost the planets temperature by about 4 degrees C (7 degrees F). That is far more than the last IPCC estimate in 2013, which projected less than eight inches of sea level rise from a melting Antarctic by 2100, with a possibility for inches more from the dramatic collapse of Antarctic glaciers.

 

Even DeConto admits that, under the model used in his paper, the timing and pace of Antarctica's ice loss is "really uncertain" -- it could be a decade or two, or three or four, before these dramatic processes start to kick in, he says. "The paper just shows the potentials, which are really big and really scary," says DeConto. But Scambos and other observers call DeContos numbers "perfectly plausible."

 

Researchers could better pin down their models if they could track the rate of sea level rise from polar ice sheet collapse in the past, but this has proven hard to do. When seas rose a whopping 13 feet per century at the end of the last glaciation (the current record-holder for known rates of sea level rise in the past), much of the water came from an ice sheet over North America, where there isn't one today. "I wouldnt use that as an analogue for the future," says paleo-geologist Andrea Dutton of the University of Florida, who wrote a recent review of past records of sea level rise. "But it has important lessons for us nonetheless -- that ice sheets can retreat suddenly and in steps instead of gradually."

 

For a better analogue of what's going on today, researchers often look to the last interglacial period, about 120,000 years ago, when temperatures were about a degree warmer than pre-industrial levels and seas were 20 to 30 feet higher than today. Ice cores from Greenland have suggested that much of that water must have come from the Antarctic. To find out just how fast sea levels rose at that time, Dutton is now looking at old corals in Mexico, Florida, and Australia; corals can be used to track sea level, since they grow in shallow waters to capture sunlight.

A map of sea level rise around the world, and how it was higher in one place than another, could be used to infer where the water came from. Success isnt guaranteed; corals are notoriously difficult to date. And whatever they find, notes Scambos, it will still be hard to draw a parallel to the modern world.

 

"That was a natural warming period in Earths history," Scambos says. "We're putting our pedal to the metal today; we're driving the system very hard."

 

James Hansen, a climatologist at Columbia University, summarized the evidence for rapid sea level rise in a recent controversial paper, raising some eyebrows at its stark warnings of catastrophe. Though many researchers have taken issue with the dramatic tone and specific details of that paper, its conclusion -- that multi-meter sea level rise is possible in the next 50, 100, or 200 years -- does not seem so alarmist in the face of other recent work.

 

"I think a lot of us who work on paleo records are all aware that a lot of change can happen very quickly -- I'm always looking at big numbers," says Dutton, who hasn't been startled by recent studies like DeConto's. "It's always going to be a difficult question to answer. Maybe we need to accept we're always going to have this uncertainty and just prepare for the worst."
