The ice rivers in the world melt faster than ever registered under the influence of climate change, according to the most comprehensive scientific analysis so far.

Mountain rivers – frozen rivers of ice – work as a supplier of freshwater for millions of people all over the world and close a sufficient amount of water to raise the levels of the global sea by 32 cm (13 inches) if they melted completely.

But since the beginning of the century, they lost more than 6500 billion tons – or 5 % – of ice.

The fusion speed is increasing. Over the past decade or so, ice river losses have been higher than a third than 2000-2011.

The study collected more than 230 regional estimate of 35 searches all over the world, making scientists more confident about the speedy melting of the ice rivers, and how they will develop in the future.

Ice rivers are excellent climate change indicators.

In a stable climate, they remain almost the same size, and gain approximately ice by the snow they lose by melting.

But the ice escapes have shrunk to a large extent everywhere over the past twenty years, as temperatures have increased due to human activities, mainly burning fossil fuels.

Between 2000 and 2023, the ice rivers were lost outside the main ice leaves in Greenland and the Antarctic continent about 270 billion tons of ice annually on average.

These numbers are not easy to get your head. So Michael Zembe, Director of the Ice World Watch Service and the main author of the study uses an analogy.

270 billion tons of ice correspond to one year. [water] He told BBC News: “The consumption of the entire world in 30 years, assuming 3 liters per person.”

The rate of change in some areas was especially extremist. Central Europe, for example, has lost 39 % of the ice ice more than 20 years ago.

The severity of this study, It was published in the Nature magazineIt is not the discovery that the ice rivers melt faster and faster – we have already known it. Instead, its strength is to attract evidence from all over the research community.

There are different ways to estimate how to change the ice flowers, from field measurements to different types of satellite data. Each has its advantages and disadvantages.

Direct measurements on the ice rivers, for example, provide very detailed information, but only available to a small part of more than 200,000 icebergs around the world.

By systematically combining these different methods, scientists can be more certain about what is going on.

Andy Shbred, head of the Geography and Environment Department at the University of Northomia, who was not a composer of modern study, said that the society’s estimates are “vital because they give people confidence to benefit from their results,” which was not a composer of modern study.

“This includes other climate scientists, governments and industry, as well as anyone interested in the effects of global warming.”

Ice rivers take some time to fully respond to climate change – depending on their size, anywhere between a few years and several decades.

This means that they will continue to melt in the coming years.

However, decisively, the amount of ice lost at the end of the century depends heavily on the amount of what humanity continues to heat the planet by launching carbon dioxide and other greenhouse gases.

This may be the difference between the loss of a quarter of ice ice in the world, if the global climate goals are achieved, and about half if the uncontrolled warming continues, the study warns.

“Each degree of temperature we can avoid will save some icy rivers, and will save us from a lot of damage,” explained Professor ZEP.

These consequences exceed local changes in landscapes and ecosystems – or “what happens in the iceberg does not remain there,” says Professor Zembe.

Hundreds of millions of people around the world depend somewhat on seasonal melting water of ice rivers, which work like giant tanks to help the population on drying. When the ice glycs disappear, as well as supply them with water.

There are global consequences as well. Even small increases at the world sea level-from mountain mountain rivers, the main ice sorts of Greenland and the southern pole, and the warmer ocean water, can significantly increase the frequency of coastal floods.

Professor Shabard said: “Every centimeter of sea levels is exposing two million people to the annual floods somewhere on our planet,” said Professor Shabard.

The levels of the global sea have already increased by more than 20 cm (8 inches) since 1900, with about half of that since the early 1990s, and the fastest increases in the coming decades are expected.
