‘Matter of survival’: All of Earth’s glacier regions shrank again in 2024, says UN

‘Preservation of glaciers is a not just an environmental, economic and societal necessity: it’s a matter of survival,’ said the UN’s World Meteorological Organisation.

ALL 19 OF the world’s glacier regions experienced a net loss of mass in 2024 for the third consecutive year, the United Nations said today, warning that saving the planet’s glaciers was now a matter of “survival”.

Five of the last six years have seen the most rapid glacier retreat on record, the UN’s World Meteorological Organisation weather, climate and water agency said, on the inaugural World Day for Glaciers.

“Preservation of glaciers is a not just an environmental, economic and societal necessity: it’s a matter of survival,” said WMO chief Celeste Saulo.

Beyond the continental ice sheets of Greenland and Antarctica, more than 275,000 glaciers worldwide cover approximately 700,000 square kilometres, said the WMO.

But they are rapidly shrinking due to climate change.

“The 2024 hydrological year marked the third year in a row in which all 19 glacier regions experienced a net mass loss,” the WMO added.

Together, they lost 450 billion tonnes of mass, the agency said, citing new data from the Swiss-based World Glacier Monitoring Service (WGMS).

It was the fourth worst year on record, with the worst being in 2023.

This week, The Journal analysed the WMO report, as well as Met Éireann data for last year, to capture the spiralling climate change crisis in Ireland and worldwide

Huge loss over 50 years

“From 2022-2024, we saw the largest three-year loss of glaciers on record,” said Saulo.

Glacier mass loss last year was relatively moderate in regions such as the Canadian Arctic and the peripheral glaciers of Greenland – but glaciers in Scandinavia, Norway’s Svalbard archipelago and North Asia experienced their worst year on record.

Based on a compilation of worldwide observations, the WGMS estimates that glaciers – separate from the continental ice sheets in Greenland and Antarctica – have lost more than 9,000 billion tonnes since records began in 1975.

“This is equivalent to a huge ice block of the size of Germany with a thickness of 25 metres,” said WGMS director Michael Zemp.

At current rates of melting, many glaciers in western Canada and the United States, Scandinavia, central Europe, the Caucasus, New Zealand “will not survive the 21st century”, said the WMO.

The agency said that together with ice sheets, glaciers store around 70% of the world’s freshwater resources, with high mountain regions acting like the world’s water towers. If they disappear, that would threaten water supplies for millions of people downstream.

‘Ignoring the problem’

For the UN, the only possible response is to combat global warming by reducing greenhouse gas emissions.

“We can negotiate many things in the end, but we cannot negotiate physical laws like the melting point of ice,” said Stefan Uhlenbrook, the WMO’s water and cryosphere director.

He declined to comment on the return to office in January of US President Donald Trump, a climate change sceptic who has pulled the United States out of the landmark 2015 Paris climate accords.

However, Uhlenbrook said that “ignoring the problem” of climate change “is maybe convenient for a short period of time”, but “that will not help us to get closer to a solution”.

For the inaugural World Day for Glaciers, the WGMS named a US glacier as its first Glacier of the Year.

The South Cascade Glacier in Washington state has been monitored continuously since 1952 and provides one of the longest uninterrupted records of glaciological mass balance in the western hemisphere.

    @087 bed: “The vast majority of climate scientists agree that climate change is real and primarily caused by human activities. Studies consistently show that approximately 97% to over 99% of actively publishing climate scientists support this consensus, based on extensive peer-reviewed research. EG:a 2013 study by Cook et al. found that 97.1% of climate science papers taking a position endorsed the idea that human activities are driving global warming. More recent analyses, such as a 2021 study by Lynas et al., surveyed over 88,000 climate-related studies and concluded that more than 99.9% of peer-reviewed papers agree on human-driven climate change. This high level of agreement reflects decades of data from temperature records, ice core samples, and greenhouse gas measurements.”

    @Thesaltyurchin: Does the glass overflow when the ice cube melts? No, the water level in the glass is unchanged. That’s because the volume of water displaced by the floating ice cube (the amount of the ice cube below water) is equal to the amount of water contained in the ice cube.

    @Pól Pot: Most glaciers are currently above sea levels, so their water will feed the ocean, when it was till now retained as ice at higher altitude. But sea level rises are mostly caused by the increase in water temperatures globally.

    @Pól Pot: First of all, when water freezes it’s density is reduced and its volume increases by about 9%. In other words, it expands. However, because ice floats a small part is above the surface so when it melts the water level should stay the same.
    Now, in the article it talks about continental ice, which is not floating, it’s on land in the form of glaciers. That’s different to sea ice.

    Try this simple experiment at home to demonstrate the concept of melting continental ice compared to sea ice. Get two glasses and 2 ice cubes. Place one of the ice cubes in one glass and then fill the glass with water to the top. With the other glass, fill it to the top with water and put in an ice cube. Which glass causes more of a mess? Your answer on a postcard please.

    This climate alarmism really needs to stop. Note how they said “glacier regions” and not simply just “glaciers” because it allows the writers to make sweeping generalisations. Glaciers in parts of Antarctica and the Karakoram range (Himalayas) have shown periods of growth or stability. The idea that every single glacier shrunk blatantly ignores regional variations. Glacial retreat did not start in the industrial era. The vast majority of glaciers began receding in the 1800s, long before Co2 levels rose significantly. This suggests natural climate cycles play a major role. We know that during the Medieval Warm Period that glaciers were smaller and during the Little Ice Age they expanded. So glacier changes are not exclusively tied to human activity. Sea level increases are not dangerous.

    At the end of the last ice age, the glaciers reached NYC and London. When the ice sheet receded, the oceans raised 100m. Ireland, the UK, Iceland, … became islands. There is a reason why all those caves with paintings found in France and Spain have been preserved as their entrance used to be above the sea level at that time.

    As far as I know, 12,000 years ago, we didn’t have the technologies, cars, tankers, planes, … we have today. There is an impact of man, but it is ALSO a natural phenomenon…

    Nature goes through cycles, and we might be accelerating it, but if our “primitive” ancestors survived it, it is dishonest to tell people that we’re on the brink of extinction…
