https://www.cfact.org/2019/10/24/worlds-largest-ice-sheet-growing/ https://earthdata.nasa.gov/learn/sensing-our-planet/unexpected-ice Paul Holland, a climate modeler with the British Antarctic Survey, has spent the last ten years studying Antarctica’s sea ice and the Southern Ocean.
Lately, he has been scrutinizing the seasons of Antarctica and how fast the ice comes and goes. Holland thinks these seasons may be a key to a conundrum:
If Earth’s temperatures are getting warmer and sea ice in the Arctic has been shrinking fast, why then is sea ice in the Antarctic slowly increasing?
"The West Antarctic ice sheet, the biggest mass of ice in the world, has been growing since the end of the nineteenth century. The Chinese study concludes that Antarctic ice exhibited a “significant negative trend” during the nineteenth century, then a “significant positive trend” throughout the 20th."

Abstract
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. This is not consistent with the previously reported insignificant changes in snow accumulation over the WAIS during the past 50 years…One possible explanation is the lack of recent ice core records in the [previously published work over the] AP [Antarctic Peninsula] and coastal zones in these studies and a high weight given to cores from the interior of Antarctica.
