Coastal erosion is a huge problem.....just from a small 20mm rise, hate to think when sea levels rise further.
Arctic 'Report Card': Scientists see glacial melt and less sea ice
NOAA chief says changes in ocean and atmosphere affect weather patterns elsewhere

SAN FRANCISCO — Arctic glaciers retreated at record levels in 2012, while summer snow melted in the region much more rapidly than it has in the past, according to a new report by the National Oceanic and Atmospheric Administration.
The findings, presented here Wednesday at the annual meeting of the American Geophysical Union, are part of the annual "Arctic Report Card," which was assembled by more than 140 scientists to assess the state of the North Pole.
The report found that Greenland's Arctic sea ice and glaciers were melting at a record rate and that sea-level rise has accelerated in the region. That has caused a population boom in lower-level organisms such as plankton, but has disrupted the life cycles of animals ranging from lemmings to the Arctic fox.
But the impacts of the warming Arctic may reach beyond the northern latitudes, said NOAA chief Jane Lubchenco during a press conference.
"What happens in the Arctic doesn't always stay in the Arctic. We're seeing Arctic changes in the ocean and the atmosphere that affect weather patterns elsewhere," she said.
In 2012, Greenland saw the warmest summer in 170 years, said Jason E. Box, of the Byrd Polar Research Center.
And September sea-ice extent — the area of water with at least 15 percent sea ice — throughout the Arctic is the lowest on record (which dates to 1979), beating the previous record set in just 2007.
.
Melting of the Greenland ice sheet also beat previous records set in 2010, with almost the entire sheet melting by mid-July, Box said.
"The 40 largest glaciers lost an area about twice that of the previous decade average," he said. "Extensive surface melting was documented for the first time at the highest elevations of the ice sheet." [Images of Melt: Earth's Vanishing Ice]
That's contributing to fast-rising seas and warmer ocean waters, Box added.
In addition, the higher melting has reduced the reflectivity of the ice surface, causing land areas to absorb more heat, which causes more melt in a self-reinforcing cycle, he said.

Summer snowmelt in the Northern Hemisphere also accelerated further decreasing the reflectivity of the land — as snow reflects more sunlight back to space than exposed land — and causing the land to trap more heat in a positive feedback cycle.
All this warming has caused a change in the organisms that live in the North, said Martin Jeffries, a geophysicist at the University of Alaska and an editor of the report card.
"Unexpectedly large phytoplankton blooms have been observed this summertime," Jeffries said. Prior estimates of how much plankton was blooming may have been 10 times too low, he added.
In areas near melting sea ice, the tundra's permafrost, or permanently frozen soil, is also greening, with a longer summer season and warmer summers, he said. Permafrost temperatures 66 feet below the surface were the highest on record at eight of 10 observatories in Alaska, and matched the 2011 records at two sites.
That soil warming is affecting some of the iconic species of the Arctic, such as the lemmings or small rodents, whose life cycles are getting more chaotic and unpredictable, Jeffries said. Warming weather has also increased pressure on the Arctic fox, which relies on the lemming as its main food source.
"The larger red fox has been expanding its range northward, leading to predation on and competition with the Arctic fox for food and resources," he said.
These changes could impact areas other than the Arctic, Lubchenco said.
"We know that melting ice in Greenland can contribute to sea-level rise around the world, and many of the biological changes we are seeing around the world affect systems elsewhere, for instance migratory birds."
For instance, rising sea levels may have contributed to record surge heights along the U.S. coastline during Hurricane Sandy, Lubchenco told LiveScience.

Keep seeing the mentally challenged point to record snowfall in parts of the world as proof positive that there is no global warming. First of all it's "climate change". If you can't get past "global warming" then you'll never get it. Record precipitation is caused by record moisture in the atmosphere. That record moisture in the atmosphere is in turn caused by record heat absorption of large bodies of water. If you don't know the difference between temperature and heat content then you don't know what you're talking about and need to step away from the microphone.

they used to think the moon had something to do with tides. I think they believe that now btw...
I know exactly what the moon is for...

The Maeslantkering is a storm surge barrier on the imaginary dividing line between the Nieuwe Waterweg waterway located at Hoek van Holland and the river the Scheur located along the cities of Maassluis and Vlaardingen up to the confluence of the rivers Oude Maas and Nieuwe Maas, Netherlands, ... which automatically closes when needed. It is part of the Delta Works and it is one of largest moving structures on Earth, rivalling the Green Bank Telescope in the USA and the Bagger 288 excavator in Germany.  A little video : |

when a big chunk falls off, silly... it will float. newsflash, the sea level still will not rise. now... you better make sure you start putting away for my $1,000,000 payment. Ever heard the term "displacement" ? Look it up. erm.. yes... I know what water displacement is... what does that have to do with my original comments about sea level rising? |

oh dear...
well, water displacement has been happening from the beginning of time and pretty much has nothing to do with humans altering the climate...
next!

You have no idea. ;D good... your ideas are f***ed. i like my ideas better. I'm just ASTOUNDED you believe they measured the height of water 100 yrs ago! carry on! |

What can you tell us about your understanding about geological surveys, Caskur ? Seriously, you really are making a fool of yourself with all this nonsense. |

Sea ice is not floating....it is ice that comes from the land and extends out from land with the base of the sea ice on the sea floor. When that melts and brings with it the ice of the land that's when sea levels rise, as what is happening with Greenland.
Glaciers break off in big chunks...sea levels have risen, there is no doubt, many Pacific Islands are suffering the effects of bigger tides.....coastal erosion is happening at such a rate surf clubs are being washed away.
Frequent major floods in the north of the country while the south fries with bushfires and the numbnuts still think it ain't happening.
The perception climate change is not from human actions is going down the plug hole, only those who know little of science still hold a sceptic stance of denial.

if anything has been displaced water-wise... then the cause of it is two floating islands the size of the USA mainland floating in the Pacific.... clean up the plastic soup to make way for the big iceberg catastrophe....I can see it now... the next big hollywoodland block buster, "The Day The Burg Melts" movie at 9....

What a lot of rot... idiots built too close to the water on the shore and didn't factor in a severe storm... that isn't rocket science.... nor is it climate change... that is just BAD engineering...period. |

Storms, according to the global warming faithfull they only came about in the last 100 years after 4 billion years of climate controlled bliss where every day was perfect ;D

You make something up Garfield and run with it everytime which is unscientific just a programmed brainwashed brain that cannot think for itself or concede the frequency of storms have changed.

The frequency of storms in your brain have changed thats for sure and thats where you get confused, your brain isn't the planet spincycle, the planets fine, its your brain that needs attention.

Part of Prez Obama's State of the Union address....clearly the deniers are the fringe cult group.....destined to join the dinosaurs..followed by a youtube vid on melting glaciers ....huge...  "After years of talking about it, we are finally poised to control our own energy future. We produce more oil at home than we have in 15 years. We have doubled the distance our cars will go on a gallon of gas, and the amount of renewable energy we generate from sources like wind and solar – with tens of thousands of good, American jobs to show for it. We produce more natural gas than ever before – and nearly everyone’s energy bill is lower because of it. And over the last four years, our emissions of the dangerous carbon pollution that threatens our planet have actually fallen. But for the sake of our children and our future, we must do more to combat climate change. Yes, it’s true that no single event makes a trend. But the fact is, the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, and floods – all are now more frequent and intense. We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science – and act before it’s too late. The good news is, we can make meaningful progress on this issue while driving strong economic growth. I urge this Congress to pursue a bipartisan, market-based solution to climate change, like the one John McCain and Joe Lieberman worked on together a few years ago. But if Congress won’t act soon to protect future generations, I will. I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy. |
