Western Europe's highest peak, Mont Blanc, has lost more than two meters (6.5 ft) in height over the past two years, French researchers said on Thursday.
A team of geographical experts who perform the measurements every two years told a news conference in Chamonix in the French Alps that the mountain was now 4,805.59 meters (15766.37 ft) high, lower than their last measurement of 4,807.81 meters (15773.65 ft) in September 2021.
According to Reuters, the experts said it is now up to climatologists, glaciologists and other scientists to look at the data collected and put forward all the theories to explain this phenomenon.
"The measurements are done on a live peak. In view of climate change, monitoring the changes will allow to better understand the impacts," glaciologist Luc Moreau said.
As alarm grows worldwide over melting glaciers, the official height of Mont Blanc has been on a downward slide for over a decade. The reading was 4,810.90 meters (15,783.79 ft) in 2007.
Switzerland's glaciers suffered their second worst melt rate this year after record 2022 losses, shrinking their overall volume by 10% over the last two years, monitoring body GLAMOS said earlier this month.

A rare New Zealand snail has been filmed for the first time squeezing an egg from its neck, delighting scientists trying to save the critically endangered meat-eating mollusk.

Threatened by coal mining in New Zealand's South Island, a small population of the Mount Augustus snail was transplanted from its forest habitat almost 20 years ago to live in chilled containers tended by humans.

Little is known about the reproduction of the shellbound critters, which can grow so large that New Zealand's conservation department calls them "giants of the snail world".

A conservation ranger said she was gobsmacked to witness a captive snail laying an egg from its neck -- a reproductive act well documented in other land snails but never filmed for this species.

"It's remarkable that in all the time we've spent caring for the snails, this is the first time we've seen one lay an egg," conservation ranger Lisa Flanagan said this week.

"We caught the action when we were weighing the snail. We turned it over to be weighed and saw the egg just starting to emerge from the snail."

Conservation department scientist Kath Walker said hard shells made it difficult to mate -- so some snails instead evolved a special "genital pore" under their head.

The Mount Augustus snail "only needs to peek out of its shell to do the business," she said.

The long-lived snails can grow to the size of a golf ball and their eggs can take more than a year to hatch.

They eat earthworms, according to New Zealand's conservation department, which they slurp up "like we eat spaghetti".

Conservation efforts suffered a drastic setback in 2011, when a faulty temperature gauge froze 800 Mount Augustus snails to death inside their climate-controlled containers.

Fewer than 2,000 snails currently live in captivity, while small populations have been re-established in the New Zealand wild.
