Researchers warn of melting Antarctic ice sheets

Scientists from Australia and elsewhere warn that runaway climate change could melt the East Antarctic ice sheet and raise sea levels by up to 5 meters. increase. The study will be published Thursday in Nature.

Reports by Australian and international researchers are another stark warning of what will happen if the 2015 Paris Agreement goal of limiting temperature rise is not met.

This study suggests that the melting of the world's largest ice sheet in East Antarctica could ultimately lead to dramatic sea-level rise, although it may be necessary to address climate change.

The East Antarctic Ice Sheet holds most of the world's glacial ice.

Researchers have described it as a "sleeping giant" that should not be awakened due to the tremendous impact its melting ice can have on the ocean surface.

Ice shelves were thought to be more stable and much less susceptible to global warming than the West Antarctic and Greenland ice sheets.

However, Scientists now believe that ice loss has been confirmed, showing clear signs of vulnerability to climate change.

Co-author of the study, Australia Melting East Antarctic ice sheets could ultimately be catastrophic, says Nellie Abram, a professor at the National University's Graduate School of Earth Sciences.

"By 2500, East Antarctica could contribute up to 5 meters of sea level rise, in addition to that from Greenland and West Antarctica," Abram said. "So it's a really high-impact scenario globally, and it gives us even more reason to make sure we're doing everything we can to avoid exceeding the 2°C warming level."

Researchers say adhering to the climate targets set in the French capital in 2015 is fundamental.

The Paris Agreement was the first to bring nearly all the countries of the world together into a single agreement to reduce greenhouse gas emissions.

The study argues that the vast East Antarctic ice sheet will remain stable if temperature rise is limited to 2 degrees Celsius, but warming will cause melting and sea level warns that it could rise many meters.

In the best-case scenario, if temperature rise is limited, snowfall may gain more ice than the ice sheet actually loses.

The study was published Thursday in the journal Nature. Stakeholders included the Australian National University, the Australian Center for Antarctic Science Research, and other experts from the UK, US and France.
