"Satellite observations of polar ice are essential for monitoring and predicting how climate change could affect ice losses and sea level rise", claimedIvins "While computer simulations allow us to make projections from climate change scenarios, the satellite measurements provide prima facie, rather irrefutable, evidence".
"Every centimeter of sea level rise leads to coastal flooding and coastal erosion, disrupting people's lives around the planet", claimed Shepherd.
Combined losses from both ice sheets came to a head at 552 billion lots each year in 2010 as well as balanced 475 billion lots each year for the rest of the years.
The study took its data from satellites that were created to measure changes to the Earth's gravitational pull that result from changes in mass, including water.
In the study, scientists have calculated that the enormous ice sheets in Greenland have lost an average of 268 billion tons of ice between 2002 and 2019.
Using an incredible amount of data regarding the thickness of ice sheets located around the world, their speed of melting, and their location relative to various coastal cities, the powerful web tool can show you exactly which cities stand to be consumed by the ocean, and which specific ice sheets will cause that to happen.
"There is a significant [melt] component also coming from the north and northeast of Greenland. And so, basically, we have the loss all around the ice sheet", she said. Past year was the hottest on record for the Arctic, with the annual minimum extent of sea ice in the region its second-lowest on record.
The study also examines ice loss in Antarctica, finding while ice loss continues in the Antarctic Peninsula and western Antarctica, including the Amundsen Sea Embayment, there was a mass gain from increased snowfall in a part of East Antarctica known as Queen Maud Land.
"In Antarctica, the mass loss in the west proceeds unabated, which is very bad news for sea level rise", Velicogna said.
Lead author of the JPL/UCI study, Isabella Velicogna while acknowledging the really hot summer in the Arctic exclaimed in a statement to JPL, "We knew this past summer had been particularly warm in Greenland, melting every corner of the ice sheet". All overall, Greenland as well as Antarctica have actually shed 6.4 trillion lots of ice given that the 1990 s.
For many scientists, Greenland is considered "ground zero" for climate change, a place where the effects of global warming are most evident - including growing temperatures, warming oceans, and melting ice.
Typically, a new satellite mission will overlap with the old one to iron out any discrepancies, but in this case, the GRACE-FO satellites weren't ready to be launched until after the previous generation of satellites went out of service.
