NASA : Antarctica is ****GAINING**** ice

[Contumacious]

Antarctica is actually gaining ice, says NASA.




A new NASA study found that Antarctica has been adding more ice than it's been losing, challenging other research, including that of the UN's Intergovernmental Panel on Climate Change, that concludes that Earth’s southern continent is losing land ice overall.

In a paper published in the Journal of Glaciology on Friday, researchers from NASA's Goddard Space Flight Center, the University of Maryland in College Park, and the engineering firm Sigma Space Corporation offer a new analysis of satellite data that show a [URL='http://www.ingentaconnect.com/content/igsoc/jog/pre-prints/content-ings_jog_15j071;jsessionid=pi1c23u2cqo4.alexandra']net gain of 112 billion tons of ice a year from 1992 to 2001 in the Antarctic ice sheet.

That gain slowed to 82 billion tons of ice per year between 2003 and 2008.


The NASA study destroys the Ludditic Claim that Globull Warming is a scientific fact .

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.

"Reporting on Antarctic ice often fails to recognise the fundamental difference between sea ice and land ice. Antarctic land ice is the ice which has accumulated over thousands of years on the Antarctica landmass through snowfall. This land ice therefore is actually stored ocean water that once evaporated and then fell as precipitation on the land. Antarctic sea ice is entirely different as it is ice which forms in salt water during the winter and almost entirely melts again in the summer.

Importantly, when land ice melts and flows into the oceans global sea levels rise on average; when sea ice melts sea levels do not change measurably but other parts of the climate system are affected, like increased absorbtion of solar energy by the darker oceans.

To summarize the situation with Antarctic ice trends:

* Antarctic land ice is decreasing at an accelerating rate
* Antarctic sea ice is increasing despite the warming Southern Ocean
"
Is Antarctica losing or gaining ice?

Good explanation of what's happening and the key difference between land and sea ice.

So...there is Global Warming/Climate Change ice and then there's regular ice, got it moron.

*Yawn*

The planet is in the midst of an ice age. And people complain that the ice age might be ending in the next 50,000 years.

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.”

LOL, ice is diminishing, despite Antarctic gains.


You, cannot make this stuff up folks.

Ah, the sweet smell of duplicate threads. When the true believers get fed their talking points, their reflex action is to immediately cut and paste.

For inexplicable reasons, deniers are claiming that study as some kind of endorsement of their paranoid conspiracy ravings and hilariously bad debunked science. Normal people, however, just see it as science working in the normal way. There are disagreements, more data is found, and things are worked out.

We're looking some major logic failures from the deniers here. The study was basically about precipitation. Global warming is about temperature, hence the world "warming". Precipitation and temperature are different things. Contrary to bad denier logic, more precipitation does not mean colder temperatures. It snows more in Antarctica as temperatures there rise, being warmer air holds more moisture, and it still never gets warm enough to rain instead of snow. Basic science, which is why deniers fail so completely at it.

Let's have some more fun with the deniers. They're heaping praise on Zwally, the study author. So what else did he say?

He says that means sea level rise elsewhere is worse than previously thought.
---
"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."
---

And he says the trend is for more warming and more melt in Antarctica
---
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."

Ooh, deniers are in a tough spot now. They just declared Zwally was infallible, then there goes Zwally supporting mainstream global warming science. So will they now backpedal frantically, or just run away?

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."

LOL, ice is diminishing, despite Antarctic gains.


You, cannot make this stuff up folks.

Have you ever been there? I have.

All the ice isn't going to melt.

I just want to know what YOU think the effects are going to be.
