The coming decades will likely witness a substantial acceleration in the melting of West Antarctica's ice shelves, even if the world cuts down on planet-warming emissions, warns new research.&nbsp;

This, as per a study Monday, published in the journal Nature Climate Change on Monday, would drive rising sea levels.

<h2>'Lost control'</h2>

The study, as per AFP, found that no matter the degree of warming this century, West Antarctica's Ice Sheet melting will speed up as warmer water in the Amundsen Sea erodes ice shelves bordering the ocean.

As per estimates, even under the best-case scenario, if humanity were to successfully limit warming to 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels, ice would still melt three times faster this century than it did last century.&nbsp;

Researchers, as per Reuters, warned that humans had "lost control" of the fate of thinning ice shelves.

"Reducing emissions can help to prevent the worst-case scenario of melting, but beyond that mitigation has a negligible impact," said Kaitlin Naughten, the study's lead author, and an ocean-ice modeller at the British Antarctic Survey.&nbsp;

"It appears that we may have lost control of the West Antarctic ice shelf melting over the 21st century."

<h2>How did researchers conclude this ominous future?</h2>

Researchers used computer modelling to determine that faster ice shelf melting is already inevitable in the coming decades as the ocean warms.

They ran simulations on Britain's national supercomputer. These simulations were based on a single model and were used to assess increases in ocean temperatures under different warming scenarios.&nbsp;

"Our simulation suggests that we are now committed to a rapid increase in the rate of ocean warming and ice shelf melting for the rest of the century," said Naughten while talking to reporters.&nbsp;

As per Tiago Segabinazzi Dotto, a senior research scientist at Britain's National Oceanography Centre, the results "need to be treated carefully since different models and even ensembles of the same model can give different responses". However, Dotto, who was not part of the study, acknowledged that the findings align with other research pointing to the imminent collapse of ice shelves in the Amundsen Sea.

Humans have 'lost control,' no amount of emission cut will slow down melting of Antarctica ice shelves: Study

A new study has revealed that Greenland's ice sheet is melting rapidly from its base, and as a result, the melting water is contributing to sea level rise around the globe.

The research study claims that Greenland's ice sheet,&nbsp;the biggest ice sheet in the world after Antarctica, has melted so much in the past decade that global sea levels rose by 1 centimetre.

During warmer months, meltwater meanders into lakes and streams on the surface of the ice sheet. Some of that water drains to the bottom of the ice sheet, falling through cracks and large fractures that form in the ice with movement and stress.

That meltwater contributes to more melting at the bottom of the ice sheet, which in turn promotes faster flow and increases the quantity of ice discharged into the ocean.

The study, published in the journal Nature Communications on Monday, says that 3.5 trillion tonnes of Greenland's ice sheet melted from 2011 to 2020.

Researchers from the University of Leeds Centre for Polar Observation and Modelling in Northern England found that it is melting at an exceptional rate, increasing 21 per cent in the past 40 years.

"Observations show that&nbsp;extreme melt events in Greenland have become more frequent and more intense—as well as more erratic—which is a global problem,"&nbsp;Lin Gilbert, co-author of the study,&nbsp;said in a statement.&nbsp;

The team used satellite data from&nbsp;the European Space Agency to estimate the elevation of the ice sheet.

It's a method that has previously been used on floating ice sheets around Antarctica.

They found that from 2011 to 2020, the runoff from Greenland's ice sheet averaged about 357 billion tonnes a year.

Greenland’s ice sheet melting faster than previously thought, raising global sea level, says study

Researchers with the National Snow and Ice Data Center said the minimum was most likely reached on Sept. 15, with 1.44 million square miles of ocean covered in ice.

Arctic sea ice melts to second lowest level on record

Describing the ice loss as "staggering," the group found that melting glaciers and ice sheets could cause sea levels to rise dramatically
