Antarctic Ice

[chuckChuck]

Contrary to what our resident denialists 'believe" NASA clearly says that the antarctic is losing ice mass.

I am sure some of the denailist could stand at the foot of the glaciers in the Columbia ice fields, with their well marked signs for their decades of shrinking, and still try to tell us that climate change is not happening! LOL

Antarctic Ice Mass Loss 2002-2020
Released on March 21, 2021

The mass of the Antarctic ice sheet has changed over the last decades. Research based on observations from the Gravity Recovery and Climate Experiment (GRACE) satellites (2002-2017) and GRACE Follow-On (since 2018 - ) indicates that between 2002 and 2020, Antarctica shed approximately 150 gigatons of ice per year, causing global sea level to rise by 0.4 millimeters per year. These images, created from GRACE and GRACE-FO data, show changes in Antarctic ice mass since 2002. Orange and red shades indicate areas that lost ice mass, while light blue shades indicate areas that gained ice mass. White indicates areas where there has been very little or no change in ice mass since 2002. Areas in East Antarctica experienced modest amounts of mass gain due to increased snow accumulation. However, this gain is more than offset by significant ice mass loss on the West Antarctic Ice Sheet (dark red) over the 19-year period. Floating ice shelves whose mass change GRACE & GRACE-FO do not measure are colored gray. The average flow lines (grey; created from satellite radar interferometry) of Antarctica’s ice converge into the locations of prominent outlet glaciers, and coincide with areas of highest mass loss (i.e., Pine Island and Thwaites glaciers in West-Antarctica). This supports other observations that warming ocean waters around Antarctica play a key role in contemporary ice mass loss.

.4 mm per year - Staples has card stock paper that thick.

Its always best to put up one of these climate posts every few days to trap trolls like chuck.

He will literally spend weeks trying to find peer reviewed articles to support his delusion.

Yes, well done Jazz.
This kept Chuck busy for an entire 10 days ( so far) trying to contradict NASA's studies indicating both sea ice gain, and ice sheet gain in Antarctica.

From NASA's own website:

The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away

thickening the ice in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7 centimeters) per year. This small thickening, sustained over thousands of years and spread over the vast expanse of these sectors of Antarctica, corresponds to a very large gain of ice

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.

Better stick with claiming that there is consensus and that the science is settled.

Ice loss mass in the antarctic is variable depending on location with some areas showing no losses and some areas gains. If you watch the video in the link below it graphically shows where ice loss is occurring.

Scientist say parts of the Antarctica have been much less affected by warming than other regions due to several factors.

"Areas in East Antarctica experienced modest amounts of mass gain due to increased snow accumulation. However, this gain is more than offset by significant ice mass loss on the West Antarctic Ice Sheet (dark red) over the 19-year period."

Denialists try to use the antarctic as a poster child for claiming climate change is not happening. A5 posts conflicting information, without providing context and explanation or references.

But when more clear cut rapid and well documented ice loss is occurring in the arctic and in mountain glaciers, the denialists will ignore it or just say the climate has always changed, ignoring mountains of physical evidence. Its all a conspiracy, no doubt!

Climate scientists know that climate change is occurring more rapidly in some regions of the world than in others. So suggesting that antarctic is representative of global climate change "not happening" is ridiculous.

Since A5 is so certain human caused climate change is not occurring and he has the "evidence" to prove it. You would think if A5 has the evidence, so would all the climate scientists, who spend their careers studying climate, would have the evidence as well?

But when A5 has been asked to name one scientific organization that says human caused climate change is not happening, all we hear is crickets!

We know why A5 doesn't answer the question!

A5 will quickly change the subject in his next post and bring up some other denialist distraction.

So if higher CO2 causes them to melt when will they stop melting?

[chuckChuck]

You would think that if climate change is not occurring or that the rockies are cooling then the 1992 sign would be in ice?

By current measurements, the Athabasca Glacier is retreating up to 16.4 ft (5 m) per year. At its most recent advancement nearly 175 years ago, the glacier covered the entire area where the Icefield Centre parking lot is today, shown in the photo. (Compare the current appearance of the glacier in this photo with the 1844 photo on the informational sign.) According to notes from the CBC documentary “Geologic Journey,” geologists predict that at its current rate of retreat, the glacier will become an alpine meadow in one hundred years. Athabasca Glacier is just one of 2,500 glaciers in British Columbia and Alberta (most are in retreat). Note that there are an estimated 200,000 glaciers across the globe.

No one says climate change isn't happening. Nor that humans are a part of it. Myself included. We have been through this dozens of times.
Enough with the futile strawman argument.

But within your own go to scientific organization, NASA, there is no consensus if Antarctric is gaining or losing mass. With the most definitive recent data from NASA indicating it is gaining mass, not getting warmer, and gaining sea ice. Yet you continue to repeat the lie that it is losing mass, contradicting the best climate scientists at NASA. You know, the ones who spend their careers studying climate, and showing us the evidence.

The reason why this is important is that all of the scary catastrophic scenarios you trot out, are based on Antarctic ice melting. And ALL of the models have it warming and melting at very high levels.
Since it is doing the opposite, and since 90% of the worlds ice is located there, all of the models are clearly wrong.
That means all of the scary future scenarios are even more wrong.
That means sea level rise is overestimated by an order of magnitude.
That means that there science is clearly not settled, nor is there consensus, nor is the debate over.

Perhaps instead of digging yourself ever deeper into a hole, you should call in the boss to take over. dml did come along to attempt some damage control after the disaster you created in the last climate change thread where you got in way over your head.

Or maybe you should leave climate science to the scientists, instead of contradicting them, spreading misinformation and fake news, and making their jobs even more difficult.

Human caused warming relative to natural warming.
