The Great Glacier Melt Spreads to Greenland’s North


The Zachariæ Isstrøm glacier holds enough water to raise the sea level 19 inches—and it’s thawing rapidly.

A Greenland glacier that holds the equivalent of 19 inches of sea-level rise has been melting at an accelerated rate since 2012, shedding as much as 5 billion metric tons a year, according to a new study published in the journal Science.

While scientists have observed the melting of Greenland’s southern glaciers, the Zachariæ Isstrøm glacier is the first major glacier in the northern part of the country to show similar losses.

“That may be an indication that climate warming is spreading toward the poles,” said Jeremie Mouginot, the study’s lead author and an associate project scientist at the University of California, Irvine.

Working with researchers at NASA’s Jet Propulsion Laboratory and the University of Kansas, the team used aerial surveys, radar, laser profiling systems, and satellite observations from multiple international space agencies to piece together 40 years of data.

They found that the Zachariæ glacier is rapidly eroding from the bottom thanks to warmer ocean water and increasing levels of meltwater that are affecting the ice sheet surface.

while its underside is compromised by currents carrying warmer ocean water, and the glacier is now breaking away into bits and pieces and retreating into deeper ground,” Eric Rignot, study coauthor and UC Irvine professor of Earth system science, said in a statement.

“From our record, it is the first time Zachariæ has retreated so far inland and has lost its floating ice shelf,” Mouginot said.

The researchers also pointed out a neighboring glacier, Nioghalvfjerdsfjorden, which is experiencing rapid ice melts but at a slower pace than Zachariæ. The two glaciers make up 12 percent of Greenland’s ice sheet. If both fully collapsed, it would mean 39 inches of sea-level rise for the world.

“At the present rate of mass loss, it would take millennia for the glacier to completely disappear,” Mouginot said. “But we do not know how fast the glacier will flow in the coming decades.”

Scientists estimate Greenland’s 650,000-square-mile ice sheet is losing 303 billion tons of ice on average per year. But more ice loss from the north could mean an acceleration of the Intergovernmental Panel on Climate Change’s projection of sea-level rise of 1.6 feet to 3.2 feet by the end of the century. If the entire ice sheet melted, it would raise sea levels by more than 20 feet worldwide.

“Not long ago, we wondered about the effect on sea levels if Earth’s major glaciers were to start retreating,” Rignot said. “We no longer need to wonder; for a couple of decades now, we’ve been able to directly observe the results of climate warming on polar glaciers. The changes are staggering and are now affecting the four corners of Greenland.”

Arctic Ice Breaks Up in Beaufort Sea


Sadly global warming folks will have fun scare-mongering with these images,  when the real problem’s are influenced by extreme climate change cycles, incoming space weather and military geoengineering. One can’t help wonder how much of this melt-off  has it’s true source in nuclear fall-out from “hot”” radioactive particles carried in the jet stream from Fukushima, nuclear testing and airborne depleted uranium from Afghanistan, Iraq and Libya. Last year Greenland lost an enormous amount of ice cover

The rapid melt north of Alaska is part of a larger phenomenon. Sea ice across the entire Arctic reached record-low levels last year. High-pressure pattern over the region kept skies clear at the very time of year when sunlight lasts the longest. In addition, larger-scale climate patterns in early June 2012 favored ice retreat along the coastlines of Alaska and Siberia.

The early onset of the spring melt and the sunny skies around the solstice increased the likelihood of heightened melt rates throughout the rest of the summer, largely by reducing albedo: the proportion of solar energy reflected back into space. If an object reflects all the energy it receives, it has an albedo of 1.0. Sea ice has high albedo because of its bright appearance. But when it starts to melt, its albedo drops from roughly 0.9 to 0.7, causing the ice to absorb more energy. Increased energy absorption leads to increased melt, which exposes ocean water. Thanks to its dark appearance, ocean water has an albedo of less than 0.1. Long, sunny days pour energy into the water, and it retains the heat throughout the summer. In September, when the Sun is low on the horizon, the heated ocean water continues melting sea ice.

Jakarta sinking by up to 10cm a year, as water supplies dry up

Jakarta flood

Increasing sea levels caused some parts of north Jakarta to flood during a high tide in 2009

Experts in Indonesia are preparing to build a huge wall to stop the ocean from swamping parts of Jakarta.

Some suburbs in the capital already go underwater when there is a big tide but the problem is expected to get even worse.

Jakarta is sinking by up to 10 centimetres a year and Indonesia’s national disaster centre says with oceans rising, large parts of the city, including the airport, will be inundated by 2030.

Flooding and high tides are already causing problems for some residents in the city of 10 million people.

Kartoyo’s roadside food stall is swimming in about 30 centimetres of water.

“It has been easier,” he said.

“This kind of flood is manageable but hopefully it won’t get higher.”

“The people here before, they couldn’t even go to the market because of the flood and the children couldn’t go to school.”

In 2009 the council built a small sea wall, but the ocean still pushes its way up through the drains and into homes.

But while some suburbs still go under and the roads are rivers, residents across town have the opposite problem.

Juriah lives next to a new development, one of the many pushing skywards as Indonesia’s economy booms, but the water supply to her suburb has disappeared.

“Because the development project next door sucks up all the water, the water stopped since the project started – about three months ago. That’s what caused it I think,” she said.

“I use a small water pump, and no water flows.

“In the beginning there was a little water but in the end it just stopped.”

‘Extensive flooding’

As developers suck up the watertable it dries out and the city slumps into the empty cavity.

“From our observations, since the 1960s the ground water has declined around 30 metres,” the head of water resources at Indonesia’s energy and mineral resources ministry, Dodid Murdohardono, said.

“The decline of ground water causes pressure in the groundwater lining and that’s why Jakarta is sinking.”

Sutopo Purwo Nugroho, an expert hydrologist with the National Disaster Mitigation Agency, says if the problem is not remedied, it could have massive consequences.

“If this continues, the area will have permanent flooding will increase especially with the additional increase of sea level in Jakarta Bay or the Java Sea, which is around seven millimetres per year,” he said.

“If our efforts aren’t fast enough compared to the causes, more than five million people could be affected.”

The city’s given itself less than 20 years to sort it out.

To curb the twin problems of the city sinking and the ground water drying up, the government’s attempting to restrict the amount industries can take.

“And in the next 30 years the government of Jakarta plans to build a giant dam around Jakarta Bay to anticipate the increased sea levels, tidal waves and land subsidence,” Mr Nugroho said.

“If the land sinking isn’t resolved, then there will be widespread tidal waves that would cause more extensive flooding in Jakarta.”

Note: I covered this story over a year ago, what’s happening to Indonesia and other islands is they’re sinking from Post Glacial Rebound Effect, which is caused by the weight of the water from melting glaciers. Basically the floor of the ocean is sinking under the excess weight, causing the islands to sink below sea level. If you go to Google Sky and zoom in around Indonesia’s coast line you can see coastal villages that have already completely submerged and that the water is approaching Jakarta’s airport. ABC is reporting the “official” storyline on sea levels rising from global warming, when that’s not the case in this situation. Also, blaming it on problems with low levels in the watertable sounds a bit far fetched when you examine the submerged coastal villages.

W. Antarctic warming among world’s fastest


by Staff Writers
Columbus, Ohio (UPI) Dec 24, 2012


disclaimer: image is for illustration purposes only

The western portion of Antarctica is warming twice as fast as previously thought and triple the world’s average temperature rise, U.S. scientists say.

The temperature in the center of western Antarctica, about 700 miles from the South Pole, has risen 4.3 degrees Fahrenheit since 1958, making that area one of the fastest-warming regions on Earth, the researchers wrote in the journal Nature Geoscience.

A 2009 measurement considered authoritative had indicated that part of the continent, which resembles a giant peninsula stretching roughly from the South Pole toward the southern tip of South America, had warmed just 2.2 degrees since 1957.

Eric J. Steig, a University of Washington researcher who led the 2009 work, told The New York Times the new research supersedes his efforts.

“I think their results are better than ours, and should be adopted as the best estimate,” he said.

Surface temperatures at the middle of the West Antarctic Ice Sheet, which covers the land, remain well below freezing most of the year, but increasingly rise above freezing during the December-through-February summer months, said the researchers from Ohio State University, the University of Wisconsin-Madison and the National Center for Atmospheric Research.

“Our record suggests that continued summer warming in West Antarctica could upset the surface mass balance of the ice sheet, so that the region could make an even bigger contribution to sea level rise than it already does,” Ohio State geography Professor David Bromwich said.

Some scientists fear the ice sheet could collapse like the Larsen B Ice Shelf did in February 2002.

“We’ve already seen enhanced surface melting contribute to the breakup of the Antarctic’s Larsen B Ice Shelf, where glaciers at the edge discharged massive sections of ice into the ocean that contributed to sea level rise,” study co-author and NCAR scientist Andrew Monaghan said.

“The stakes would be much higher if a similar event occurred to an ice shelf restraining one of the enormous WAIS glaciers,” he said.

The ice-sheet breakup could take centuries, but could raise global sea levels 10 feet or more, the researchers said.

The base of the ice sheet sits below sea level in a configuration that makes it especially vulnerable, they said.

Their research was funded by the U.S. government’s National Science Foundation

Note: What about the earth heating up from below the surface as temperatures are apparently rising due to magma rising to the surface, which is indicated by the great number of volcano’s erupting above ground and at the bottom of the oceans? Surely that will speed up the melting of the ice, indicating that their computer models are way off if they haven’t factored that in to the data.
