NASA Study Shows Global Sea Ice Diminishing, Despite Antarctic Gains
Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new NASA study finds. As a whole, the planet has been shedding sea ice at an average annual rate of 13,500 square miles (35,000 square kilometers) since 1979, the equivalent of losing an area of sea ice larger than the state of Maryland every year.

“Even though Antarctic sea ice reached a new record maximum this past September, global sea ice is still decreasing,” said Claire Parkinson, author of the study and climate scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “That’s because the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice.”


NASA Study Shows Global Sea Ice Diminishing, Despite Antarctic Gains

dudette, did you really just post that? funny stuff right there. You probably won't get it since you posted it, but think about what sea ice is for moment, and what would be wrong with diminishing sea ice. What are the hazards of that dear?

Maybe this will help.

Greenland loses ice to the sea mainly through two processes: the shedding of icebergs from glaciers that run into the sea, and surface melt runoff.

Observations from the Jason series have revolutionized scientists' understanding of contemporary sea level rise and its causes. We know that today's sea level rise is about one-third the result of the warming of existing ocean water, with the remainder coming from melting land ice.



“Solid ice losses have been studied in great detail by scientists for years, but the melt water component, despite being the dominant agent in the ice sheet's mass balance, has received comparatively less study,” Smith said. “This is particularly true for the surface water hydrology on top of the ice sheet, which has received very little study.”



The handful of ice sheet surface hydrology studies have mostly focused on Greenland’s massive melt water lakes, which can disappear in a matter of hours, engulfed by the ice. But Smith and his team believe that rivers sinking into holes in the ice are the main agent transporting water from the top to the bottom of the ice sheet.



“While lake drainages do suddenly pump a large volume of water all at once to the ice sheet, in fact the amount of water they put into the ice sheet is almost trivial compared to the flux of water moving through these intricate, very efficient drainage networks [of rivers] that spread across the surface of the ablation [or melt] zone each summer,” Smith said.



Besides contributing to sea level rise, melt water runoff also accelerates ice loss: when the water percolates through the ice sheet and reaches the rock below, it slightly lifts the ice, helping it flow faster toward the ocean. Also, the intensity and area of surface melt are projected to increase with climate change.

Warming Seas, Melting Ice Sheets

wow, the ultimate stupid posted up for all to see. Carla says Sea ice melt increases sea level rise. Now I'm a fairly reasonable person, so, carla, please go look that up again. remember if you add ice to a glass full of liquid, note the level of the fluid, when the ice melts will the fluid rise? Please, please, answer the question. I want to believe you're smarter than that. maybe look up volume.

LOL, that's from the OP's link.

what is from the OP that stated sea ice melt causes sea level rise? post the excerpt that stated that.

The information I posted is from Owl's NASA link.

Let's say this is true. How is supposed to effect us?

Do you think polar bears will appear in your backyard?

For some weird reason, nitwits always think of "global" as their backyard. Seriously, if you're this ignorant, there's no point in having us having a discussion.

I don't have time for you.

Is this guy a nitwit?

"Harold Warren Lewis, a respected physicist who had previously advised both the U.S. Government and the Pentagon on various matters including missile defence and nuclear winter, shocked his peers when he disseminated his letter of resignation from the American Physical Society."

- See more at: Top U.S. physicist claims global warming is a “scam”

"Lewis accused the American Physical Society of supporting “the global warming scam, with the trillions of dollars driving it that has corrupted so many scientists.” The physicist’s letter contained a number of complaints, including the APS’ lack of a response to his endeavours to gather a committee to evaluate evidence for a human link to climate change. Lewis revealed that global warming was “the greatest and most successful pseudoscientific fraud” he has even seen in his career."

I don't believe he's a nitwit, but I do believe he's wrong. I also suspect he's a liar. He is a member of the GWPF think tank, who have rejected requests to disclose its funding sources on at least four different occasions.

Accounts show extent to which secretive think tank is funded by anonymous donors rather than income from membership fees

And from Wikipedia..

"Its income suggests that it only has about 80 members, which means that it is a fringe group promoting the interests of a very small number of politically motivated campaigners."

In March 2012, The Guardian revealed that it had uncovered emails in which Michael Hintze, founder of the hedge fund CQS and a major donor to the UK Conservative Party, disclosed having donated to GWPF; the previous October, Hintze had been at the center of a funding scandal that led to the resignation of then-Secretary of State for Defence Liam Fox and the dismissal of Hintze's then-charity adviser, Oliver Hylton.

Chris Huhne, former UK Secretary of State for Energy and Climate Change attacked Lord Lawson's influential climate sceptic think-tank.

In 2014 the Charity Commission ruled that the GWPF had has breached rules on impartiality in its climate change coverage, blurred fact and comment and demonstrated a clear bias.

NASA Study: Mass Gains of Antarctic Ice Sheet Greater than Losses

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.

“We’re essentially in agreement with other studies that show an increase in ice discharge in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica,” said Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published on Oct. 30 in the Journal of Glaciology. “Our main disagreement is for East Antarctica and the interior of West Antarctica – there, we see an ice gain that exceeds the losses in the other areas.” Zwally added that his team “measured small height changes over large areas, as well as the large changes observed over smaller areas.”

Scientists calculate how much the ice sheet is growing or shrinking from the changes in surface height that are measured by the satellite altimeters. In locations where the amount of new snowfall accumulating on an ice sheet is not equal to the ice flow downward and outward to the ocean, the surface height changes and the ice-sheet mass grows or shrinks.

But it might only take a few decades for Antarctica’s growth to reverse, according to Zwally. “If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years -- I don’t think there will be enough snowfall increase to offset these losses.”

The study analyzed changes in the surface height of the Antarctic ice sheet measured by radar altimeters on two European Space Agency European Remote Sensing (ERS) satellites, spanning from 1992 to 2001, and by the laser altimeter on NASA’s Ice, Cloud, and land Elevation Satellite (ICESat) from 2003 to 2008.

Zwally said that while other scientists have assumed that the gains in elevation seen in East Antarctica are due to recent increases in snow accumulation, his team used meteorological data beginning in 1979 to show that the snowfall in East Antarctica actually decreased by 11 billion tons per year during both the ERS and ICESat periods. They also used information on snow accumulation for tens of thousands of years, derived by other scientists from ice cores, to conclude that East Antarctica has been thickening for a very long time.

“At the end of the last Ice Age, the air became warmer and carried more moisture across the continent, doubling the amount of snow dropped on the ice sheet,” Zwally said.

dudette, did you really just post that? funny stuff right there. You probably won't get it since you posted it, but think about what sea ice is for moment, and what would be wrong with diminishing sea ice. What are the hazards of that dear?

Maybe this will help.

Greenland loses ice to the sea mainly through two processes: the shedding of icebergs from glaciers that run into the sea, and surface melt runoff.

Observations from the Jason series have revolutionized scientists' understanding of contemporary sea level rise and its causes. We know that today's sea level rise is about one-third the result of the warming of existing ocean water, with the remainder coming from melting land ice.



“Solid ice losses have been studied in great detail by scientists for years, but the melt water component, despite being the dominant agent in the ice sheet's mass balance, has received comparatively less study,” Smith said. “This is particularly true for the surface water hydrology on top of the ice sheet, which has received very little study.”



The handful of ice sheet surface hydrology studies have mostly focused on Greenland’s massive melt water lakes, which can disappear in a matter of hours, engulfed by the ice. But Smith and his team believe that rivers sinking into holes in the ice are the main agent transporting water from the top to the bottom of the ice sheet.



“While lake drainages do suddenly pump a large volume of water all at once to the ice sheet, in fact the amount of water they put into the ice sheet is almost trivial compared to the flux of water moving through these intricate, very efficient drainage networks [of rivers] that spread across the surface of the ablation [or melt] zone each summer,” Smith said.



Besides contributing to sea level rise, melt water runoff also accelerates ice loss: when the water percolates through the ice sheet and reaches the rock below, it slightly lifts the ice, helping it flow faster toward the ocean. Also, the intensity and area of surface melt are projected to increase with climate change.

wow, the ultimate stupid posted up for all to see. Carla says Sea ice melt increases sea level rise. Now I'm a fairly reasonable person, so, carla, please go look that up again. remember if you add ice to a glass full of liquid, note the level of the fluid, when the ice melts will the fluid rise? Please, please, answer the question. I want to believe you're smarter than that. maybe look up volume.

LOL, that's from the OP's link.

what is from the OP that stated sea ice melt causes sea level rise? post the excerpt that stated that.

The information I posted is from Owl's NASA link.

excerpt from the link:]

"Zwally’s team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.

“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said. “But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”"

"Oddly, for years they dined out on talk of 'melting polar ice caps', always and clearly in the plural. That's what the theory and their models said. Just not what reality said. After confrontation with defiant reality became too much, Al Gore famously shifted his rhetoric to refer only to 'the north polar ice cap'.

Eyeah..

These gains far outpace losses in places where ice is dwindling, including the Antarctic Peninsula and the Thwaites and Pine Island area of West Antarctica, according to the news release.

NASA's analysis of ice core samples show that Antarctica's extra snowfall, which began 10,000 years ago, has been compacting into solid ice, thickening West Antarctica's sheet by .7 inches per year.

But climate change deniers shouldn't get smug just yet.

We're only a few decades away from net ice loss in Antarctica, NASA experts say.

“If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years -- I don’t think there will be enough snowfall increase to offset these losses," Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, said in a news release.

So I'm still curious where you got your news from. It wasn't from that report, so again, if sea ice melts does sea level rise? tough question to answer especially for you.

I've already told you that the info I posted is from the same link...just scroll down.

I'm still looking for where it states that sea ice melt increases sea level.. Please post up that excerpt please.

looks like you have one more to add.

Looking more closely at Zwally's study, it doesn't seem as good as the others. It's using older tech, ICEsat, and it tries to combine radar and laser altimeter measurements, separated in time, with a gap between them. Not easy, because the laser measures the top of the snow, while the radar penetrates a variable distance into it, depending how firmly the snow is packed.

In contrast, one of the other studies uses the gravity measurements of the GRACE satellite. Much simpler in comparison, and using the same instrument the whole time. Gravity just depends on the mass, which is the thing we're trying to measure. And another study uses the European Cryosat-2 data. Newer satellite, better data. And the two studies with the more accurate and simpler data agree with each other, and not with Zwally.

Fortunately, work will be ongoing, with the USA launching ICEsat-2 in 2018. That is, unless the deniers get their way, as deniers are more or less demanding that NASA cease all earth science missions, being that more accurate data is politically inconvenient to the deniers.

LOL, that's from the OP's link.

what is from the OP that stated sea ice melt causes sea level rise? post the excerpt that stated that.

What you do is click on the link in the OP, then scroll down.

here is what I found sweetie:

"Zwally’s team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.

“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said. “But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”"

I don't believe you read the article I posted correctly.


Greenland loses ice to the sea mainly through twoprocesses: the shedding of icebergs from glaciers that run into the sea, and surface melt runoff.

Observations from the Jason series have revolutionized scientists' understanding of contemporary sea level rise and its causes. We know that today's sea level rise is about one-third the result of the warming of existing ocean water, with the remainder coming from melting land ice.



“Solid ice losses have been studied in great detail by scientists for years, but the melt water component, despite being the dominant agent in the ice sheet's mass balance, has received comparatively less study,” Smith said. “This is particularly true for the surface water hydrology on top of the ice sheet, which has received very little study.”



The handful of ice sheet surface hydrology studies have mostly focused on Greenland’s massive melt water lakes, which can disappear in a matter of hours, engulfed by the ice. But Smith and his team believe that rivers sinking into holes in the ice are the main agent transporting water from the top to the bottom of the ice sheet.



“While lake drainages do suddenly pump a large volume of water all at once to the ice sheet, in fact the amount of water they put into the ice sheet is almost trivial compared to the flux of water moving through these intricate, very efficient drainage networks [of rivers] that spread across the surface of the ablation [or melt] zone each summer,” Smith said.



Besides contributing to sea level rise, melt water runoff also accelerates ice loss: when the water percolates through the ice sheet and reaches the rock below, it slightly lifts the ice, helping it flow faster toward the ocean. Also, the intensity and area of surface melt are projected to increase with climate change.

again, it states melting land ice, still not sure where you get the rise from sea ice. Please explain.

still land ice, waiting on that explanation of sea ice melt and sea rise.
