In a study published in 2017 scientists were able to combine information from satellite altimetry, gravimetry, and GPS to measure the ice balance in East Antarctica from 2003-2013 When looking at this data they were unable to confirm Zwally’s findings. Also, in order to calibrate their measurements, Zwally’s team bounced lasers of the Southern Ocean which may not have been reliable. That result is controversial. Abstract. After all, how can sea levels be rising from glaciers melting if Antarctica is gaining mass year after year? "It should not take away from the concern about climate warming.". If global warming caused less ice in West Antarctica, how did it cause more ice in Eastern Antarctica? The study would turn out to not be accurate. These new findings were based on data that came from studying changes in the surface height of the Antarctic ice sheet using radar altimeters. Although found only in the Arctic and the Antarctic, it influences Earth’s climate in big ways. This information was not at all in line with previous findings on the subject which insisted that Antarctica has been losing ice mass because of global warming. The November gain was the highest on record, by a wide margin. Sea ice surrounding Antarctica has long baffled scientists. The growing season has not ended, and 2019 Arctic sea-ice extent is already higher than the previous four years and six out of … To better understand this influence, an initial state intercomparison exercise (initMIP) has been developed to compare, … Published on 11/13/2015 at 5:00 AM. It will accomplish this by firing 10,000 laser pulses per second toward the surface of the Earth and timing how long it takes for the pulses to get back to the satellite. Here’s the money quote: When averaged over the whole WAIS [West Antarctic Ice Sheet] , SMB [surface mass balance] shows a significantly negative trend (-1.9± 2.2Gt yr-1decade-1, p<0.01) [loss of ice] during the 19th century, but a significantly positive trend (5.4± 2.9Gt decade-1, p<0.01) [gain in ice] in the 20th century. The social media posts have been talking about how this proves that climate change was a hoax all along. Meanwhile, the team found the East Antarctic ice sheet has remained relatively balanced during the past 25 years, gaining an average of 5.5 billion tons (5 billion metric tons) of ice per year. Meanwhile, the team found the East Antarctic ice sheet has remained relatively balanced during the past 25 years, gaining an average of 5.5 billion tons (5 billion metric tons) of ice per year. https://tambonthongchai.com/2019/06/27/antarctica/. As the article opens with “you won’t see this on the BBC or in the MSM”. These gains were not just in recent years but had been the result of increased snowfall over the past 10,000 years or since the last ice age. Since 2015 scientists have had a chance to look over the data and have had time to do a few follow-up studies and the results are clear. Meant to write ‘Paul’. Antarctica is shedding ice at a staggering rate. A gigaton (Gt) corresponds to a billion metric tons, or 1.1 billion U.S. tons. Antarctic land ice is the ice which has accumulated over thousands of years on the Antarctica landmass through snowfall. Between 2003 and 2088, the net gain slowed to 82 billion tons of ice each year. Spatial and temporal Antarctic Ice Sheet mass trends, glacio‐isostatic adjustment, and surface processes from a joint inversion of satellite altimeter, gravity, and GPS data. Sea ice waxes and wanes with the seasons, but minimum and maximum extents rarely match from year to year; over years and decades, summer and winter extents vary. Which may explain why you have heard nothing about this new publication which has been accepted in Journal of Geophysical Research-Atmospheres but isn’t in print yet: “A New 200‐Year Spatial Reconstruction of West Antarctic Surface Mass Balance,” by Yetang Yang (Shandang Normal University, China) and five co-authors. The data was collected using two European Space Agency European Remote Sensing satellites and NASA’s Ice, Cloud, and land Elevation Satellite. Its bright surface reflects sunlight back into space. “Antarctic sea ice extents reached a record high of 12.8 × 106 km2 in 2014”-> 2014: More ice than ever-> 2017: Lowest level since 1979-> 2018/2019: More ice than 2017 -> growing! In 2015 a study was published by NASA, the lead author was Jay Zwally, a glaciologist with NASA Goddard Space Flight Center. The November gain was the highest on record, by a wide margin. “The WAIS experienced a significant loss of ice in the 19th century when it was colder than the 20th century average. In the past week or so I have been reading a few articles and social media posts on the subject of Antarctica gaining ice mass. However, it was not enough to offset the losses in West Antarctica and the Antarctic Peninsula. Although measurements are rather hard to come by, it is clear that the Southern Ocean surrounding Antarctica has warmed a few tenths of a degree (C) since 1900. 121, Issue. Whereas Arctic sea ice mostly sits in the middle of land-locked ocean—which is more sensitive to sunlight and warming air—Antarctic sea ice surrounds land and is constantly exposed to high winds and waves. Increasing the moisture would therefore increase the snow load which should increase the ice mass balance, which is why I find this result (and Jay Zwally’s) not particularly surprising. Some comments on the AEP thread seem to have gone into the cold store a.k.a spam folder? The study goes on to say that sea levels cannot be rising because of glaciers melting in Antarctica because its actually gaining ice. When we look at all the available data the big picture becomes clear. That search would likely uncover one 2015 publication by NASA’s Jay Zwally in the Journal of Glaciology using actual weather data that showed increasing snowfall, primarily over East Antarctica, was adding a small amount of ice. Scientists tend to agree ice loss has increased in western Antarctica and the Antarctic Peninsula has increased. The results are very similar for both time-slice patterns driven by the underlying time … In short, climate change is real and always has been. “Still, when considering the 40-y record as a whole, the Antarctic sea ice continues to have a positive overall trend in yearly average ice extents.” 1984? In spite of those heart-wrenching stories about melting ice in Antarctica, a new NASA study has found that mass gains of the Antarctic Ice Sheet are greater than the losses on … Much like in 2015, Zwally’s upcoming study will run up against the so-called “consensus,” including a paper published by a team of 80 scientists in the journal Nature on Wednesday.
