“Changes in climate forcing directly affect the rate of ice growth,” he said, “not the amount of ice.” Year to year cooling in autumn, for example, may cause faster ice growth … Fortunately, Antarctica is increasing its ice level faster than it is decreasing. Greenland and Antarctica are gaining ice inland, but still losing it overall. However, a new study from earlier this year finds this is not the case, as Pat Michaels explains: The West Antarctic Ice Sheet is growing, but I bet you didn’t read about it in the news. (CNN) — Antarctica is gaining more ice than it has lost, according to a new study by NASA. As a result of these complex expected changes, there are a number of uncertainties in past, present and future ice sheet mass balance. We compare the results with a surface mass balance model to deduce the ice sheet mass balance. Over the past … However it is gaining ice extent. Antarctic ice looms. I can’t believe you missed the “raspberry snow” story. On that day, on that island, the Antarctic was hotter than Cape Town. and "The ice gained in the interior is roughly balanced by the ice loss at the edges." In … While there is evidence that the ice cap in East Antarctica is growing, it has been widely claimed that it has been melting back in the West.. Global Sea Ice Growing. (Greg Roberts, The Australian) Arguments that we needn't worry about … But decades of remote sensing and seafloor … Reply. The extra snowfall that began 10,000 years ago has been slowly accumulating on the ice sheet and compacting into solid ice over millennia, thickening the ice in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7 centimeters) per year. Global warming is evaporating more moisture into the atmosphere which causes more rain. Zwally said his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west. These factors affect Antarctic sea ice growth and melt processes, thickness evolution and drift and impart high regional and seasonal variability. 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. Antarctica is losing far more ice than it’s gaining and the rates of loss are increasing as time goes on. Peter Carroll says: March 2, 2020 at 11:39 am . Every year Antarctic sea ice undergoes a six‐fold change in ice‐covered area; it is one of the largest seasonal signals on earth. Literally. This small thickening, sustained over thousands of years and spread over the vast expanse of these sectors of Antarctica … Close to 70% of the world’s freshwater is locked into Antarctica’s snow and ice… (Greg Roberts, The Australian) Antarctica is a continent with 98% of the land covered by ice, and is surrounded by ocean that has much of its surface covered by seasonal sea ice. The 1981 to 2010 median is in dark gray. Greenland and Antarctica are gaining ice inland, but still losing it overall. However, it is more likely that the Greenland and Antarctic ice sheets will lose mass over the next century, with rapid coastal changes, increases in ice flow and ice-shelf collapse all likely 4. May 1, 2020 Frank Jones. NASA recently released a study suggesting that the Antarctic Ice Sheet is gaining more ice than it is losing -- a finding that, at first blush, ... Oct 28, 2020 … More rain is freshening the surface water enabling more sea surface ice to form. By Paul Homewood . 0. Issues NASA Study: Antarctica is Gaining Ice Findings challenge those of UN panel studying climate change. A new NASA study found that Antarctica is gaining more ice than it's losing. The Antarctic ice sheets are losing mass at an accelerating rate. The palaeoclimate record shows, however, that it has retreated during previous episodes of prolonged warmth. One new paper 1, which states there has been less surface melting recently than in past years, has been cited as “proof” that there’s no global warming.Other evidence that the amount of sea ice around Antarctica seems to be increasing slightly 2-4 is … IMAGE: A BAND OF CLOUDS IN AN ATMOSPHERIC RIVER EXTENDING FROM SOUTH AMERICA TO THE ANTARCTIC SEA ICE ZONE ON SEPT. 16, 2017.view more CREDIT: NASA. address your point and quite well describe what is going on down there. 121, Issue. The total mass loss increased from 40 ± 9 Gt/y in 1979–1990 to 50 ± 14 Gt/y in 1989–2000, 166 ± 18 … Climate Myth: Antarctica is gaining ice "[Ice] is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap." After being above average for much of the austral winter and spring, Antarctic sea ice extent has only increased-further into the summer months, to a level now tracking the 1979-1990 average.. Antarctica’s unusual cold is having an impact on the its sea ice. In the tug-of-war between coastal melting and inland ice buildup, the meltdown is winning in both Greenland and Antarctica. 2, p. 182. It is caused by a bloom of algae and was noted by Aristotle, in his writings, only 1000 years ago. Initial observations from NASA’s ICESat-2 satellite in 2018 and 2019 reveal how the Greenland and Antarctic ice sheets have changed since the … Geo Guy, I think that upon reading the text and not just looking at the figures, the two sentences "While the interior of East Antarctica is gaining land ice, overall Antarctica is losing land ice at an accelerating rate. " A recent paper claims Antarctica’s net ice loss has dramatically increased in recent years, but forthcoming research will challenge that claim. Most studies on Antarctic sea ice trends focus on changes in ice extent. February extents are depicted in red, September extents in green, and all other extents in black. I guess it refers to newly deposited Antarctic snow and ice blowing a raspberry at climate scientists. Antarctic sea ice is gaining sea ice but Antarctica is losing land ice at an accelerating rate, which has implications for sea level rise. The Ross Ice Shelf, for example, is more than 370 miles … In the tug-of-war between coastal melting and inland ice buildup, the meltdown is winning in both Greenland and Antarctica. Is Antarctica melting or is it gaining ice? The gray areas around the median … Ice loss was limited to West Antarctica and the Antarctic Peninsula; the bigger East Antarctic sheet gained mass over that time. Climate myth: Antarctica is gaining ice "[Ice] is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap." Page 5 of 8 from the intermediate version of Antarctica is gaining ice. But in 2015, a group of NASA scientists published a controversial study that found Antarctica was instead gaining ice. The graph above shows Arctic sea ice extent as of January 6, 2020, along with daily ice extent data for four previous years and the record low year. Astronaut Scott Kelly just broke the record for the longest US single spaceflight, and the pictures he's taken along the way are incredible . It contradicted prominent previous findings — … Figure 4: Monthly average sea ice extents for the Southern Hemisphere, January 1979–December 2018. Reporting on Antarctic ice … The NASA team combined space- and land-based measurements and found so much snow dropping in East Antarctica that even with drastic melting elsewhere, the continent was adding some 80 billion tons of ice annually. For Holland, it was more important to look at how fast the ice was growing or shrinking from season to season. The data show that the continent is gaining more ice in some areas, like parts of East Antarctica. Much of the ice edge of Antarctica is made up of massive cliffs, its size and expanse almost incomprehensible from photographs. That process is already underway, says Scambos, and … 2019 to 2020 is shown in blue, 2018 to 2019 in green, 2017 to 2018 in orange, 2016 to 2017 in brown, 2015 to 2016 in purple, and 2012 to 2013 in dotted brown. According to the Gravity satellite measurements (GRACE) Antarctica is losing ice mass. We use updated drainage inventory, ice thickness, and ice velocity data to calculate the grounding line ice discharge of 176 basins draining the Antarctic Ice Sheet from 1979 to 2017. The phrase “at a glacial pace” once invoked a sense of slow and unchangeable movement, an almost imperceptible motion. Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as … There has been lots of talk lately about Antarctica and whether or not the continent’s giant ice sheet is melting. Glacier in Antarctica / AP Morgan Chalfant-November 3, 2015 10:21 AM A new study is being misinterpreted to say that Antarctica is gaining ice, but it's still losing huge amounts of ice every year. The Antarctic ice sheet gathered mass at the rate of 112 billion tons of ice every year from 1992 to 2001, they said, which slowed to 82 billion tons of ice gain per year between 2003 and 2008. Journal of Geophysical Research: Earth Surface, Vol. (B) Monthly deviations … If all the ice in West Antarctica melts and slides into the sea, it is likely to contribute several meters to sea level rise. In short, climate change is real and always has been. Initial observations from NASA’s ICESat-2 satellite in 2018 and 2019 reveal how the Greenland and Antarctic ice sheets have changed since the … A team of NASA scientists examined by satellite images the altitude of the ice sheet and they concluded that the increase is favorable.The methods used to reach this conclusion are worthy of recognition, but this finding generated conflicts between investigations of more than a decade. Single-letter abbreviations are used for months. In other areas, it is losing ice, and more rapidly. (Inset) The 40-y average annual cycle. But that isn't a sign that climate change is slowing down. March 1, 2020 at 10:00 pm . Published April 30, 2020. This in turn enables the sea ice extent to increase. The East Antarctic ice sheet may be gaining mass in the current, warming climate. NASA says Antarctica is gaining ice. It is however highly variable and frequently exposed to strong storms, high winds and waves. How do scientists explain and engage with this increasingly urgent climate crisis?
