Say What!?! NASA study: Mass gains of Antarctic Ice Sheet greater than losses

[depotoo]

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.

The biggest hoax in history.

There are now three new studies out that show the IPCC line of thought total BS. Antarctica has gained over 220 billion tons of ice this year alone.. Then we have Greenland which has shown a 300% increase in Ice this year alone and over the last five years the ice growth has surpassed the loss by 200%...

The AGW meme is crashing as the empirical evidence disproving it keeps piling up, just like the Ice is..

 

[S.J.]

Weather happens.

 

[Billy_Bob]

From the Dutch Meteorological Institute (DMI):

"Greenland is blowing away all records for ice gain this year. They have gained almost 200 billion tons of snow and ice over the past two months, which is more than 50% above normal. The surface of the ice gained more than 200 billion tons during the previous 12 months.

Five hundred billion tons of snow falls on Greenland every year. All of that has to return to the sea by either melt or glacier calving. Otherwise the ice would be piled up to the top of the atmosphere."

The Hits keep on coming...

I believe that we are reaching a point where the empirical evidence cannot be ignored or explained away by lies. And the general public is becoming aware of just how they have been lied to and abused..

Zwally (an Arctic death spiralist) had two NASA laser altimetry papers in 2011 and 2012 that showed Antarctic gains of 45 and 65 Gt. I defy anyone to find them now. They went down the memory hole. As inconvenient findings often do.

Well the way back machine still has them..

The 2011 paper looks interesting..

 

[Billy_Bob]

Even during the periods that they say were warming the actual ice mass loss/recovered was near zero. And each year ended in positive gains... OUCH! And NASA knew they had gains of 164 billion tons of ice while touting the hype that we were all going to burn and flood... Now that is stunning.. Evidence of intentional lying by NASA.... positive gains as late as 2005, 2006, 2008 and 2009 they NEW WERE HAPPENING!

 

[IanC]

GRACE was a new technology that was showing ice loss, probably through poor calibration. There is a lot of slack in the system that can be used to get the results they wanted. But only for so long, sooner or later a correction back to reality must happen. For SLR as well as ice. That's why new adjustments have to be brought online.

I hope no one missed the point that increased discharge - which was not disputed - is what is raising the Earth's sea level.

Using measurements of the elevation of the Antarctic ice sheet made by a suite of satellites, the researchers found that the Southern Antarctic Peninsula showed no signs of change up to 2009. Around 2009, multiple glaciers along a vast coastal expanse, measuring some 750km in length, suddenly started to shed ice into the ocean at a nearly constant rate of 60 cubic km, or about 55 trillion litres of water, each year.

This makes the region the second largest contributor to sea level rise in Antarctica and the ice loss shows no sign of waning.

Dr Bert Wouters, a Marie Curie Fellow at the University of Bristol, who lead the study said: "To date, the glaciers added roughly 300 cubic km of water to the ocean. That's the equivalent of the volume of nearly 350,000 Empire State Buildings combined."

The changes were observed using the CryoSat-2 satellite, a mission of the European Space Agency dedicated to remote-sensing of ice. From an altitude of about 700km, the satellite sends a radar pulse to Earth, which is reflected by the ice and subsequently received back at the satellite. From the time the pulse takes to travel, the elevation of the ice surface can retrieved with incredible accuracy. By analysing roughly 5 years of the data, the researchers found that the ice surface of some of the glaciers is currently going down by as much as 4m each year.

The ice loss in the region is so large that it causes small changes in the gravity field of the Earth, which can be detected by another satellite mission, the Gravity Recovery and Climate Experiment (GRACE).

Looks like the loss of ice is much greater than the inland gain.

"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."

Two differant methods of measurement and two differant results. So we need some field work to resolve the differances In the meantime, note that both speak of the increased temperatures increasing snowfall in the interior. How does that fit in your nonsense about cooling?

You dont get it... the ocean circulation was warm which caused the interior to warm. That has now changed by empirical evidence. this caused an increase in snow and ice creation, funny how the earth does that to maintain balance. There has been no step warming, only cyclical natural variation change due to ocean circulations as we see that warming is now gone and no step increase is seen..

 

[CrusaderFrank]

Er, the ice gained because of global warming...Denier!!!

We have consensus!!

You mean the increased discharge that was negated due to increased snow and ice creation? As there is no sea level change recorded or observed.

 

[depotoo]

Do you not see they are stating the new ice makes up, plus some, for the losses. What don't you get?

And are you now agreeing the 'settled' science isn't so settled.

I see a thread title like this and do not have to open it to see who is going to post what.

Great for a morning laugh. Thanks

Seems Greenland is showing changes, as well-

Despite fears that global warming is harming the Arctic region faster than the rest of the world, Greenland is defying climate scientists and currently growing at its fastest rate in four years.

The Danish Meteorological Institute reports that Greenland’s ice sheet has seen more growth so far this year than in the last four years. Greenland’s growth in 2015 is also higher than the mean growth for 1990 to 2011.
