Antarctic land ice vanishing faster

[mamooth]

As measurements keep getting get better, we keep finding things are worse than originally thought. That generally goes for all climate science; the IPCC and other "alarmists" have been erring on the side of making predictions that are less severe than the reality.

Abstract
We use 3 years of Cryosat-2 radar altimeter data to develop the first comprehensive assessment of Antarctic ice sheet elevation change. This new data set provides near-continuous (96%) coverage of the entire continent, extending to within 215 km of the South Pole and leading to a fivefold increase in the sampling of coastal regions where the vast majority of all ice losses occur. Between 2010 and 2013, West Antarctica, East Antarctica, and the Antarctic Peninsula changed in mass by −134 ± 27, −3 ± 36, and −23 ± 18 Gt yr−1, respectively. In West Antarctica, signals of imbalance are present in areas that were poorly surveyed by past missions, contributing additional losses that bring altimeter observations closer to estimates based on other geodetic techniques. However, the average rate of ice thinning in West Antarctica has also continued to rise, and mass losses from this sector are now 31% greater than over the period 2005–2010.

Mass loss of the Amundsen Sea Embayment of West Antarctica from four independent techniques - Sutterley - Geophysical Research Letters - Wiley Online Library
---
Abstract
We compare four independent estimates of the mass balance of the Amundsen Sea Embayment of West Antarctica, an area experiencing rapid retreat and mass loss to the sea. We use ICESat and Operation IceBridge laser altimetry, Envisat radar altimetry, GRACE time-variable gravity, RACMO2.3 surface mass balance, ice velocity from imaging radars and ice thickness from radar sounders. The four methods agree in terms of mass loss and acceleration in loss at the regional scale. Over 1992–2013, the mass loss is 83±5 Gt/yr with an acceleration of 6.1±0.7 Gt/yr2. During the common period 2003–2009, the mass loss is 84±10 Gt/yr with an acceleration of 16.3±5.6 Gt/yr2, nearly three times the acceleration over 1992–2013. Over 2003–2011, the mass loss is 102±10 Gt/yr with an acceleration of 15.7±4.0 Gt/yr2. The results reconcile independent mass balance estimates in a setting dominated by change in ice dynamics with significant variability in surface mass balance.

So as you change the methods you use to measure, you get the results you are looking for?

 

[mamooth]

Marty, don't you regard it as sad that your kneejerk response to any new data is to instantly declare it has to be fraudulent?

Most others do regard it as sad. You're a conspiracy cultist, just like most other deniers.

The harder you guys try, the more desperate you look.

I wonder what beautiful mysteries lie beneath the ice in Antarctica.​

Talking about Antarctic ice-melt these days is like a mousefart in a Hurricane.

So, the denialists have only nonsense for an answer to real research.

Have you ever, once...just once....questioned the information being spoon-fed you?

 

[Old Rocks]

Have you ever just once questioned why all the Scientific Societies, all the National Academies of Science, and all the major Universities all state AGW is real? That is scientists from every country and culture in the world.

Perhaps you would be wiser to question the people who you get your information from.

Changing the metrics and then trying to apply them to the old standard is not science.. ITS LYING... HIDING THE TRUTH....MISINFORMATION MONGERING......

This is a dam alarmist desperation play...

The fact is, the land ice is much the same as it has been for over 8,000 years. Even the paper admits this... They admit that there have been fluctuations in ice coverage and this is NOT OUTSIDE OF NORMAL VARIATION..

 

[Old Rocks]

Really? So you know all this, but don't know how to link to it. Typical for an adolescent. How you coming on that Phd in atmospheric physics. LOL

i guess the OP's link is magical and nonexistent..... Moron!!!

As you guys used to like to say....follow the money. Now that you are using politics to buy scientific opinion, you don't suggest following the money any more. Wonder why?

He would never have guessed that you were talking about the paper in the OP....magic again. The information you referenced is not visible to true believers. It appears as just a blank space.

Might ask how they square this supposed unprecedented loss of land ice with the decelerating rate of sea level increase over the past three quarters of a century or so....more magic I guess. CO2 can apparently do anything....except perhaps demonstrate how it does of its tricks in a laboratory setting. The magic apparently only works in the wild.

Cool more land to use. Hope nature speeds up already.
