A fresh study conducted by NASA suggests Antarctica is gaining more ice than what it is losing. This report is contradicting various other reports by other climate activists around the globe.
"We are essentially in agreement with other studies that show an increase in ice discharge in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica," said Jay Zwally, glaciologist with NASA Goddard Space Flight Centre in Greenbelt, Maryland in a report published in the Journal of Glaciology. One of the main points of disagreement is for East Antarctica and the interior of West Antarctica."Here, we see an ice gain that exceeds the losses in the other areas," he added.
According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.
"If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same, rate they've been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years," Zwally said in the report. According to Zwally, the growth may reverse in 2-3 decades.Zwally also hinted that Antarctica may not be responsible for increase in sea levels, which meant that some other factor was not accounted for."It will contribute to solving the problem of Antarctica's mass balance by providing a long-term record of elevation changes," said ICESat-2 deputy project scientist and glaciologist Tom Neumann from NASA's Goddard Space Flight Center.
Antarctica, the southernmost continent and site of the South Pole, is a virtually uninhabited, ice-covered landmass. Most cruises to the continent visit the Antarctic Peninsula, which stretches toward South America. About 98% of Antarctica is covered by ice that averages 1.9 kilometers (1.2 mi) in thickness, which extends to all but the northernmost reaches of the Antartic Peninsula.
