Greenland already locked in to major sea level rise: study

Greenland locked in to major sea,According to a study released on Monday, the melting of Greenland’s ice sheet will result in significant sea level rise even in the absence of any additional future global warming, with potentially “ominous” repercussions for this century if temperatures continue to climb.

Depending on humankind’s attempts to stop global warming, rising sea levels—driven primarily by melting ice sheets in Greenland and Antarctica—are expected to redraw the world over millennia and eventually flood land that is currently home to hundreds of millions of people.

According to NASA, the Arctic region is currently heating up more quickly than the rest of the planet, which is the main cause of the Earth’s oceans being swollen.

According to a recent study published in Nature Climate Change, the Greenland ice sheet will lose 3.3 percent of its volume due to warming, contributing 27.4 millimetres to sea level rise, regardless of any future fossil fuel emissions.

While the researchers were unable to provide a specific timeline, they did state that the majority of it would occur by 2100, which suggests that the hazards this century may be underestimated by the present sea level rise model forecasts.

Because future warming is not taken into consideration, the “shocking” figures are also a lowest estimate, according to lead author Jason Box of the National Geological Survey of Denmark and Greenland.

“It is a lower bound with caution. For further commitment, the climate merely has to continue warming near Greenland “He informed AFP.

According to the study, the sea level might rise by about 78 cm if the high melting rates recorded in 2012 became a yearly occurrence. This would be enough to inundate large stretches of low-lying coastlines and intensify floods and storm surges.

According to the authors, this “should serve as an awful prediction for Greenland’s trajectory during a 21st century of warming.”

The Intergovernmental Panel on Climate Change (IPCC) predicted that the Greenland ice sheet will contribute up to 18 cm of sea level rise by 2100 under the highest emissions scenario in a key study on climate science released last year.

The most recent research conducted by Box’s team, Greenland locked in to major sea one of the authors of that article, indicates that those figures may be “too low.”

To estimate how the Greenland ice sheet will respond to the current warming, Box and colleagues used two decades of observations and observational data rather than computer models.
Every year, snowfall adds mass to the upper portions of the ice sheet, but since the 1980s, the region has had an ice “budget deficit,” meaning that it is losing more ice than it is gaining due to surface melting and other processes.
