Headline discussing the threat of melting glaciers to European villages, with a date of August 3, 2025.

In a small village in Switzerlandโ€™s beautiful Loetschental valley, Matthias Bellwald walks down the main street and is greeted every few steps by locals who smile or offer a handshake or friendly word.

Mr Bellwald is a mayor, but this isnโ€™t his village. Two months ago his home, three miles away in Blatten, was wiped off the map when part of the mountain and glacier collapsed into the valley.

The villageโ€™s 300 residents had been evacuated days earlier, after geologists warned that the mountain was increasingly unstable. But they lost their homes, their church, their hotels and their farms.

Lukas Kalbermatten also lost the hotel that had been in his family for three generations.”The feeling of the village, all the small alleys through the houses, the church, the memories you had when you played there as a childโ€ฆ all this is gone.”

Though the disaster shocked Switzerland, some two thirds of the country is mountainous, and climate scientists warn that the glaciers and the permafrost โ€“ the glue that holds the mountains together โ€“ are thawing as the global temperature increases, making landslides more likely. Protecting areas will be costly.

BBC INDEPTH? Donโ€™t make me laugh.

A properly objective report would have also mentioned the downhill march of Swiss glaciers in the Little Ice Age.

My review of Brian Faganโ€™s excellent book, The Little Ice Age, gives a flavour of just how dreadful those times were. [Sections in italics are direct quotes]:


We tend to regard alpine landscapes today such as those in Switzerland as being picturesque and think that the people there live in a beautiful rural idyll. It was not always so. In the 16th Century the occasional traveller would remark on the poverty and suffering of those who lived on the marginal lands in the glacierโ€™s shadow. At that time Chamonix was an obscure poverty stricken parish in โ€œa poor country of barren mountains never free of glaciers and frostsโ€ฆhalf the year there is no sunโ€ฆthe corn is gathered in the snowโ€ฆand is so mouldy it has to be heated in the ovenโ€. Even animals were said to refuse bread made from Chamonix wheat. Avalanches caused by low temperatures and deep snowfall were a constant hazard. In 1575 a visitor described the village as โ€œa place covered with glaciersโ€ฆoften the fields are entirely swept away and the wheat blown into the woods and onto the glaciersโ€.

In 1589 the Allalin glacier in Switzerland descended so low that it blocked the Saas valley, forming a lake. The moraine broke a few months later, sending floods downstream. Seven years later 70 people died when similar floods from the Gietroz glacier submerged the town of Martigny.

As the glaciers relentlessly pushed downslope, thousands of acres of farm land were ruined and many villages were left uninhabitable such as La Bois where a government official noted โ€œwhere there are still six houses. all uninhabited save two, in which live some wretched women and childrenโ€ฆAbove and adjoining the village there is a great and horrible glacier of great and incalculable volume which can promise nothing but the destruction of the houses and lands which still remainโ€. Eventually the village was completely abandoned.

The same official visited the hamlet of La Rosiere in 1616 and found โ€œThe great glacier of La Rosiere every now and then goes bounding and thrashing or descendingโ€ฆThere have been destroyed 43 journaux of land with nothing but stones and 8 houses, 7 barns and 5 little granges have been entirely ruined and destroyedโ€.

Alpine glaciers, which had already advanced steadily between 1546 and 1590, moved aggressively forward again between 1600 and 1616. Villages that had flourished since medieval times were in danger or already destroyed. During the long period of glacial retreat and relative quiet in earlier times, opportunistic farmers had cleared land within a kilometer of what seemed to them to be stationary ice sheets. Now their descendants paid the price with their villages and livelihoods threatened.

Between 1627 and 1633 Chamonix lost a third of its land through avalanches, snow, glaciers and flooding, and the remaining hectares were under constant threat. In 1642 the Des Bois glacier advanced โ€œover a musket shot every day, even in Augustโ€.

By this time people near the ice front were planting only oats and a little barley in fields that were under snow for most of the year. Their forefathers had paid their tithes in wheat. Now they obtained but one harvest in three and even the grain rotted after harvesting. โ€œThe people here are so badly fed they are dark and wretched and seem only half aliveโ€.

In 1715 the village of Le Pre-du-Bar vanished under a glacier caused landslide. The glacial high tide in the Alps came around 1750 and gradually the glaciers began their retreat, much to the relief of the people who lived there.


The BBC might like to consider that none of these villages were there three hundred years ago because the glaciers were there instead.

I somehow doubt anybody in Switzerland would want a return to those days.

Climate change causes mega-tsunamiโ€™s that shake the Earth for nine days

Experts admit their tsunami models were completely wrong, but, ooh, spooky, spooky: climate change causes โ€œglobal vibrations beneath our feetโ€. And sheโ€™s a professor โ€” itโ€™s embarrassing. This is superstitious bead-wringing with mystical phrases.

Every scientific curiosity becomes a climate prayer

A year ago, within an hour, 120 seismometers all over the world started to record a freakish shake every 90 seconds like a metronome. People watching the waves were baffled. And even more so that it didnโ€™t stop within a few minutes but continued on all day and night, eventually ringing out for nine days.

It turned out to be a landslide in an oddly shaped  fjord in Eastern Greenland. A 1.2 kilometre mountain of rock and ice had collapsed, sending a 110m wall of water 10 kilometers across the gorge to smash 200 metres up the other side of the fjord. The water then came back down and the return wave apparently kept slopping back and forward for nine days. Spare a thought for the fish.

Thus โ€œ10,000 swimming poolsโ€ worth of repeating tsunamis keep rattling seismic detectors for days and then kept 68 scientists busy for a year figuring out what it was.

Predictably, they say, it was caused by climate change, because rock slides and ice collapses have never happened before, or at least, not while humans had a global seismographic network.

And not a single climate model predicted this.

Apparently theย Dickson fjordย has a 90 degree bend at end near the mouth, and a glacial dam at the other end which stopped the energy dissipating, making it the perfect resonant chamber.ย  Then in a freak of nature, the landslide hit at the perfect 90 degree angle in the ideal chamber to drive seismologists bonkers.

Naturally,ย Science, the formerly esteemed top journal had to squeeze the absurd climate propaganda near the endย of the press release, so giants likeย The Guardianย could turn it into a Shock and Awe Headline.

Experts admit their tsunami models were completely wrong, but, ooh, spooky, spooky: climate change causes โ€œglobal vibrations beneath our feetโ€. And sheโ€™s a professor โ€” itโ€™s embarrassing. This is superstitious bead-wringing with mystical phrases.

Prof Anne Mangeney, a landslide modeller at the Institut de Physique du Globe de Paris in France, who was part of the team, said: โ€œThis unique long-duration tsunami challenged the classical models that we previously used to simulate just a few hours of tsunami propagation โ€“ we had to go to an unprecedentedly high numerical resolution. This opens up new avenues for tsunami modelling.โ€

Such events will become more common as global temperatures continue to rise. โ€œEven more profoundly, for the first time, we can quite clearly see this event, triggered by climate change, caused a global vibration beneath all of our feet, everywhere around the world,โ€ said Mangeney. โ€œThose vibrations travelled from Greenland to Antarctica in less than an hour. So weโ€™ve seen an impact from climate change impacting the entire world within just an hour.โ€

Holy smoke: โ€œclimate change impacts the Earth in a hourโ€, but we see the impact of the sun in just 8 minutes. So? Thanks to climate change, Greenland is about the same temperature now as it was in 1880.

We canโ€™t โ€œclearly seeโ€ any thing at all. Thereโ€™s no trend, no data, no evidence. What if a warmer world means the ice doesnโ€™t build up and go boom, but just melts away gradually. Drip, drip, drip, eh?

So the misinformation continues. In modern science lamb chops cause tsunamis, Ford F-250โ€™s shake the world, and only solar panels can save us.

Itโ€™s all part of the hypnosis. Adults in the room need to remind the children that glaciers and rockslides have been happening for millions of years. (Eg Lieseki and Raymo) Then when kids grow up and become professors they might not say silly things.

Scientists have discovered the cause of giant underwater landslides in Antarctica which they believe could have generated tsunami waves that stretched across the Southern Ocean.

An international team of researchers has uncovered layers of weak, fossilised and biologically-rich sediments hundreds of metres beneath the seafloor.

These formed beneath extensive areas of underwater landslides, many of which cut more than 100metres into the seabed.

Writing in Nature Communications, the scientists say these weak layers โ€“ made up of historic biological material โ€“ made the area susceptible to failure in the face of earthquakes and other seismic activity.

They also highlight that the layers formed at a time when temperatures in Antarctica were up to 3ยฐC warmer than they are today, when sea levels were higher and ice sheets much smaller than at present.

With the planet currently going through a period of extensive climate change โ€“ once again including warmer waters, rising sea levels and shrinking ice sheets โ€“ researchers believe there is the potential for such incidents to be replicated.

Through analysing the effects of past underwater landslides, they say future seismic events off the coast of Antarctica might again pose a risk of tsunami waves reaching the shores of South America, New Zealand and South East Asia.

The landslides were discovered in the eastern Ross Sea in 2017 by an international team of scientists during the Italian ODYSSEA expedition.

Scientists revisited the area in 2018 as part of the International Ocean Discovery Program (IODP) Expedition 374 where they collected sediment cores extending hundreds of meters beneath the seafloor.

By analysing those samples, they found microscopic fossils which painted a picture of what the climate would have been like in the region millions of years ago and how it created the weak layers deep under the Ross Sea.

The new study was led by Dr Jenny Gales, Lecturer in Hydrography and Ocean Exploration at the University of Plymouth, and part of IODP Expedition 374.

She said: โ€œSubmarine landslides are a major geohazard with the potential to trigger tsunamis that can lead to huge loss of life. The landslides can also destroy infrastructure including subsea cables, meaning future such events would create a wide range of economic and social impacts. Thanks to exceptional preservation of the sediments beneath the seafloor, we have for the first time been able to show what caused these historical landslides in this region of Antarctica and also indicate the impact of such events in the future. Our findings highlight how we urgently need to enhance our understanding of how global climate change might influence the stability of these regions and potential for future tsunamis.โ€

Professor Rob McKay, Director of the Antarctic Research Centre at Victoria University of Wellington and co-chief scientist of IODP Expedition 374, added: โ€œThe main aim of our IODP drilling project in 2018 was to understand the influence that warming climate and oceans have had on melting Antarcticaโ€™s ice sheets in the past in order to understand its future response. However, when Dr Gales and her colleagues on board the OGS Explora mapped these huge scarps and landslides the year before, it was quite a revelation to us to see how the past changes in climates we were studying from drilling were directly linked to submarine landslide events of this magnitude. We did not expect to see this, and it is a potential hazard that certainly warrants further investigation.โ€

Laura De Santis, a researcher at the National Institute of Oceanography and Applied Geophysics in Italy, and also co-chief scientist of IODP Expedition 374, said: โ€œThe sediment cores we analysed were obtained as part of IODP, the international seafloor scientific drilling project that has been active in the field of geoscience for over 50 years. The project aims to explore the history of planet Earth, including ocean currents, climate change, marine life and mineral deposits, by studying sediments and rocks beneath the seafloor.โ€

Jan Sverre Laberg, from The Arctic University of Norway, Tromsรธ, said: โ€œGiant submarine landslides have occurred both on southern and northern high latitude continental margins, including the Antarctic and Norwegian continental margins. More knowledge on these events in Antarctica will also be relevant for submarine geohazard evaluation offshore Norway.โ€

Dr Amelia Shevenell, Associate Professor of Geological Oceanography at University of South Florida, College of Marine Science, said: โ€œThis study illustrates the importance of scientific ocean drilling and marine geology for understanding both past climate change and identifying regions susceptible to natural hazards to inform infrastructure decisions. Large landslides along the Antarctic margin have the potential to trigger tsunamis, which may result in substantial loss of life far from their origin. Further, national Antarctic programs are investigating the possibility of installing submarine cables to improve communications from Antarctic research bases. Our study, from the slope of the Ross Sea, is located seaward of major national and international research stations, indicating that marine geological and geophysical feasibility studies are essential to the success of these projects and should be completed early in the development process, before countries invest in and depend on this communication infrastructure.โ€
