Scientists fear more ice collapses in Italian Alps after deadly avalanche

Scientists believe there will be more glacial collapses in the Italian Alps due to the hot summer and the climate crisis after an avalanche killed six people and injured eight others on Sunday.

Experts quoted by the Corriere della Sera daily said they feared further collapses of ice after the deadly avalanche on the mountain of Marmolada, the highest in the Italian Dolomites, near the hamlet of Punta Rocca

Massimo Frezzotti, a science professor at Roma Tre University, told AFP the collapse was caused by unusually warm weather linked to global warming, with precipitation down 40 to 50 percent during a dry winter.

“The current conditions of the glacier correspond to mid-August, not early July,” he said.

Glacier specialist Renato Colucci told the Italian agency AGI that the phenomenon was “bound to repeat itself”, because “for weeks the temperatures at altitude in the Alps have been well beyond normal values”.

The recent warm temperatures had produced a large quantity of water from the melting glacier that accumulated at the bottom of the block of ice and caused it to collapse, he added.

The Marmolada glacier is the largest in the Dolomites mountain range, which is part of the Italian Alps and situated on the northern face of Marmolada.

The glacier, nicknamed “the queen of the Dolomites”, feeds the Avisio river and overlooks Lake Fedaia in the autonomous Italian province of Trento.

According to a March report by the UN Intergovernmental Panel on Climate Change (IPCC), melting ice and snow is one of 10 major threats caused by global warming, disrupting ecosystems and infrastructure.

The IPCC has said glaciers in Scandinavia, central Europe and the Caucasus could lose between 60 and 80 percent of their mass by the end of the century.

The traditional way of life of people such as the Sami in Finland’s Lapland, who raise reindeer, has already been affected.

Thawing permafrost is also hampering economic activity in Canada and Russia.

'Extreme' climate blamed for world's worst wine harvest in 62 years

“Extreme environmental conditions” including droughts, fires and other problems with climate were mostly to blame for the drastic fall, said the International Organisation of Vine and Wine (OIV) that covers nearly 50 wine producing countries.

Australia and Italy suffered the worst, with 26 and 23 percent drops. Spain lost more than a fifth of its production. Harvests in Chile and South Africa were down by more than 10 percent.

The OIV said the global grape harvest was the worst since 1961, and worse even than its early estimates in November.

In further bad news for winemakers, customers drank three per cent less wine in 2023, the French-based intergovernmental body said.

Director John Barker highlighted “drought, extreme heat and fires, as well as heavy rain causing flooding and fungal diseases across major northern and southern hemisphere wine producing regions.”

Although he said climate problems were not solely to blame for the drastic fall, “the most important challenge that the sector faces is climate change.

“We know that the grapevine, as a long-lived plant cultivated in often vulnerable areas, is strongly affected by climate change,” he added.

France bucked the falling harvest trend, with a four percent rise, making it by far the world’s biggest wine producer.

Wine consumption last year was however at its lowest level since 1996, confirming a fall-off over the last five years, according to the figures.

The trend is partly due to price rises caused by inflation and a sharp fall in wine drinking in China – down a quarter – due to its economic slowdown.

The Portuguese, French and Italians remain the world’s biggest wine drinkers per capita.

Barker said the underlying decrease in consumption is being “driven by demographic and lifestyle changes. But given the very complicated influences on global demand at the moment,” it is difficult to know whether the fall will continue.

“What is clear is that inflation is the dominant factor affecting demand in 2023,” he said.

Land given over to growing grapes to eat or for wine fell for the third consecutive year to 7.2 million hectares (17.7 million acres).

But India became one of the global top 10 grape producers for the first time with a three percent rise in the size of its vineyards.

France, however, has been pruning its vineyards back slightly, with its government paying winemakers to pull up vines or to distil their grapes.

The collapse of the Italian harvest to its lowest level since 1950 does not necessarily mean there will be a similar contraction there, said Barker.

Between floods and hailstones, and damp weather causing mildew in the centre and south of the country, the fall was “clearly linked to meteorological conditions”, he said.
