As we've noted before, the West Antarctic ice sheet is of particular concern because, like a building that stands on an uneven foundation, it is inherently unstable, making it especially vulnerable to the warming climate.
Back in 1992 till 2017 the continent lost nearly 84 billion tons of ice per year, and within the next five years after that it sailed over to nearly 240 billion tons each year. From 2012 to 2017, the melt rate increased to more than 241 billion tons a year (219 billion metric tons). Scientists have always been eyeing the West Antarctic ice sheet as the least stable region of the continent, and a NASA-lead study confirmed that ice losses were accelerating there earlier this year. This led to the fact that each year the water level increases by 3 mm.
That leap in ice loss is concentrated in West Antarctica, where losses jumped from 53 billion metric tons of ice in 1992 to 159 billion metric tons in 2017. It for the fast five years i.e. from 2012-2017 melting charges in the Antarctica Ocean tripled between these five years, according to the printed news on the journal Nature. If this continues, then any time soon there may cause a drop down to the ice, and sea level could potentially rise. 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. There's enough frost stacked on top of Antarctica that is enough to raise the sea level worldwide by approximately 200 feet. Knowing how much ice it's losing is key to understanding the impacts of climate change now and its pace in the future.
Scientists have reviewed decades of satellite measurements to reveal how and why Antarctica's glaciers, ice shelves and sea ice are changing.
