Switzerland has lost 10% of its glaciers in just two years in ‘catastrophic’ ice melt, study shows
Switzerland has lost 10% of its glaciers in just two years, research shows, after high summer heat and low winter snowfall.
The country lost as much ice in the 24 months as it did in the three decades before 1990, researchers said, describing the ice melt as “catastrophic”.
Switzerland – home to the most glaciers of any country in Europe – has seen 4% of its total glacier volume disappear in 2023, the second-biggest decline in a single year on top of a record 6% drop in 2022.
The team at Glacier Monitoring Switzerland (GLAMOS) said the “massive ice loss” stemmed from a winter with very low volumes of snow – which falls on top of glaciers and protects them from exposure to direct sunlight – and high summer temperatures.
All of Switzerland – where the Alps cut a swathe through most of the southern and central parts of the country – was affected, though glaciers in the southern and eastern regions melted almost as fast as in 2022’s record thaw.
In some places, GLAMOS had to cease monitoring due to the melt.

Images posted on social media by Matthias Huss, who leads GLAMOS, during data collection trips in recent weeks showed new lakes forming next to glacier tongues, as well as streams of melt water running through ice caves, and bare rock poking out from thinning ice.
“This year was very problematic for glaciers because there was really little snow in winter, and the summer was very warm,” he said.
“The combination of these two factors is the worst that can happen to glaciers.”
More than half of the glaciers in the Alps are in Switzerland where temperatures are rising by around twice the global average due to climate change.
In some places, bodies lost long ago have been recovered as ice sheets have shrunk.
“Melting of several metres was measured in southern Valais (region) and the Engadin valley at a level above 3,200 metres (10,500ft), an altitude at which glaciers had until recently preserved their equilibrium,” the GLAMOS team said.

The average loss of ice thickness was up to three metres (10ft) in places such as the Gries Glacier in Valais, the Basodino Glacier in the southern canton, or region, of Ticino, and the Vadret Pers glacier system in eastern Graubunden.
The situation in some parts of the central Bernese Oberland and the Valais was less dramatic – such as for the Aletsch Glacier in Valais and Plaine Morte Glacier in the canton of Bern, because they enjoyed more winter snowfall.
But even in such areas, “a loss of over two metres of the average ice thickness is extremely high,” the team said.
In a stark and direct intervention, Martin Griffiths, the former UN humanitarian chief, has described the situation in Gaza as genocide.
The statement, made during an interview I conducted with Griffiths on The World, marks one of the most pointed accusations yet from a figure known to be deeply embedded in the world of international politics and diplomacy.
“I think now we’ve got to the point this is unequivocal. Of course it is genocide. Just as it is weaponising aid.
“We don’t need to look behind ourselves to see that’s the case. That should encourage us even more because we, of course, all doubted whether it would come to that level of definition.
“We all doubted whether famine is actually there. I think starvation is killing people. That’s bad enough. We don’t have to worry about famine, which is obviously there lurking in the shadows.
“Also, genocide… of course that’s what has happened. We only need to look at the statements made. Prime Minister Netanyahu has the virtue of being very clear about his objectives.”

Ex-Israeli aide dismisses genocide claims
His choice of words is extraordinary – not just for its gravity, but because it’s Griffiths who is saying it.
A veteran diplomat with decades of experience navigating complex international crises, Griffiths is known for his calm and thoughtful demeanour – not for inflammatory language.
For him to use the term “genocide” in a television interview signals a significant shift in how some within the international system are now interpreting events on the ground in Gaza – 20 months since Israel launched its war.

The timing is also noteworthy.

He said: “What more evidence do you need now? Will you act decisively to prevent genocide and to ensure respect for international humanitarian law? Or will you say instead: ‘we did all we could?'”
Whilst he stopped short, his tone showed a clear change in how leading international figures now view the direction of Israeli military operations in Gaza; staggering civilian deaths, and the statements made by Israeli officials prosecuting this war.

Griffiths’ remarks now go a step further.
It comes as the British government continues to grapple with public anger over the mounting civilian toll – and faces growing scrutiny over its continued arms exports to Israel.

Children ‘should be treated in UK’
This latest statement by Griffiths doesn’t just reflect humanitarian concern.
As a former ambassador, he knows the weight his words carry.
And with the humanitarian crisis in Gaza worsening, his warning challenges Israel’s allies to ask deeply uncomfortable questions.

Lawyers representing Israel against accusations brought by South Africa to the International Court of Justice last year – accusing its actions in Gaza of amounting to genocide – called the claims “unfounded”, “absurd” and amounting to “libel”.
They went on to say Israel respected international law and had a right to defend itself.

More than 40% of Europe slides into drought, including pockets of Greece, southern Italy and Spain
Well over a third of Europe, including parts of holiday destinations like Spain, Greece and Italy, are now in drought.
March was Europe’s warmest on record – a trend driven by climate change – and also saw below average rain across large parts of the north and east of the continent.
Now 41.2% of Europe finds itself in some form of drought, according to the latest update from the EU’s European Drought Observatory, which covers 11 to 20 May.
It is most acute in pockets of south-eastern Spain, Cyprus, Greece and Albania, where the strongest “alert” category has been issued, as well as parts of Poland and Ukraine.
But broad stretches of northern and eastern Europe through France, Germany, Poland and Ukraine also drying up, sowing concerns about crop yields.
On Thursday, the UK’s Environment Agency officially declared a drought in North West England after river and reservoir levels were licked away by a dry spring.

Greece tourism is ‘unsustainable’
In Greece, “overtourism” from millions flocking to its beaches adds further pressure to water supplies, said Nikitas Mylopoulos, professor of water resource management at Thessaly University.
“The tourist sector is unsustainable and there is no planning… leading to a tremendous rise in water demand in summer,” he told Sky News.
“The islands have an intense problem of drought and water scarcity.”
Islands like Santorini and Mykonos are now forced to ship in water from Athens or desalination plants to provide for showers and swimming pools. In the past, many residents could make do with local methods like rainwater harvesting.
But agriculture is a far bigger drain on the country’s water, with waste rife and policies lacking, said Prof Mylopoulos.

‘Tropical nights’ soar in European hotspots
Wildfire season could be ‘particularly difficult’
This year’s hot and dry conditions are also fuelling the risk of yet another fierce wildfire season in Greece.
Last week civil protection minister Ioannis Kefalogiannis warned of a “particularly difficult” summer.
He said a record 18,000 firefighters have been deployed and the drone fleet almost doubled in a bid to combat fires being fuelled by a hotter climate.
Droughts and their causes are more complicated, but scientists at World Weather Attribution say global warming is exacerbating drought in some parts of the world, including around the Mediterranean.

They found the drought of 2022, which spread across the Northern Hemisphere, was made 20 times more likely by climate change.
The International Hydropower Association said drought and intense rain in Europe are pushing power plants to “operate at the limits of their existing equipment”.
Extreme weather costs the EU about €28.3bn (£23.8bn) in lost crops and livestock per year, according to insurance firm Howden.
Hayley Fowler, professor of climate change impacts at Newcastle University, said: “With global warming, we expect more prolonged and intense droughts and heatwaves punctuated by more intense rainfall, possibly causing flash floods.
“In recent years, we have experienced more of these atmospheric blocks, causing record heat and persistent drought, as well as severe flooding in other locations in Europe.
“Recent months have been no different, with prolonged dry conditions and heatwaves in northern Europe and floods in southern Europe.”
At least 117 people have died and others are still missing after heavy flooding in Nigeria, an emergency official said.
Authorities initially said 21 people had died but this figure has today risen significantly.
Media reports quoting local government officials said a dam collapse has worsened the situation.
Ibrahim Hussaini, head of Niger State Emergency Management Agency, said some 3,000 houses were underwater in two communities.
Videos posted on social media show floodwater sweeping through neighbourhoods, with rooftops barely visible above the brown currents. One clip shows a tanker floating through a town.

The chairman of the Mokwa local government area suggested poor infrastructure has worsened the impact of the flooding.
Jibril Muregi has appealed to the government to start “long overdue” construction of waterways in the area under a climate resilience project.

In a similar occurrence last September, torrential rains and a dam collapse in Nigeria’s northeastern Maiduguri caused severe flooding, leaving at least 30 people dead and displacing millions.
Nigeria is prone to flooding during the rainy season, which began in April – and flooding is becoming more common and extreme as the climate warms.

Hotter air is thirstier and can hold more moisture – about 7% more for every 1C warmer – meaning it unleashes heavier flooding when it rains.
Violent rain, which killed hundreds of people in Nigeria during 2022, was made at least 80 times more likely and 20% more intense by climate change, analysis by World Weather Attribution found.
