The Calderone ice formation in central Italy once laid claim to being the southernmost glacier in Europe - before it shrank and split into much-diminished glacierets. As climate change drives global temperatures ever higher, the glacier risks melting away into the geological record books altogether.


Situated in a deep valley in the Gran Sasso d'Italia, a massif in the Apennine Mountains, the Calderone glacier first split two decades ago.

It became the southernmost glacier in Europe after the Corral del Veleta in the Sierra Nevada in Spain melted in the early 20th century.

But since then it has been in headlong retreat: its volume reducing by around 90 percent between 1916 and 1990, according to a 2010 study in the Journal of Glaciology.

"This was the southernmost glacier in Europe and that's why it was an icon and a symbol, but now it is shrinking more and more," glaciologist Massimo Frezzotti told AFP.

"We estimate it could disappear within the next 10-20 years," said Frezzotti, who is president of the Italian Glaciological Committee.

He said the ablation season - a period, usually the summer, when glaciers lose more mass than they gain - effectively "disappeared because temperatures increased".


"The duration of the ablation seasons became longer, the rainfall remained constant but there is a reduction in the snowfall and of course the mass balance of the glacier has shrunk more and more," he said.

Massimo Pecci, another member of the group, has been studying the Calderone glacier for the past 25 years.

"Since 2000 we have been witnessing a gradual reduction of the thickness, of the area and a further fragmentation into smaller glacierets," Pecci said.

Global warming caused by human activity - mostly the burning of fossil fuels - has pushed up Earth's average surface temperature 1.1 degrees Celsius (2.0 degrees Fahrenheit) compared to mid-19th century levels.

Most of that increase has occurred in the past 50 years.

The United Nations revealed in its latest report that the impact of climate change that scientists have been warning about for years is here.

The Italian side of the Mont Blanc massif is also currently at melting point and could collapse, threatening the village below, while the heat in Sicily is set to break European records, with a scorching 48.8 degrees C reported near Syracuse on Wednesday.


The future of Italy over the coming decades is projected to see more extreme weather, including heatwaves, drought and rising sea levels.

"We don't know yet how the story is going to end... let's hope it's not
going to end," Pecci said.
