"With the rising global temperatures, #glaciers in #Sikkim Himalayan have been melting rapidly, giving rise to many #GlacierLakes and expanding the already existing ones in the region. There are currently more than 300 glacial lakes in Sikkim Himalayan. Out of these, 10 have been identified as vulnerable to outburst #floods."
‘Dramatic’ acceleration: Switzerland has lost 10% of its glaciers in the last two years
Glaciers across the entire country were affected, with those in southern and eastern Switzerland melting almost as much this year as in the record year of 2022.
Some glacial rivers are turning toxic. Here’s why.
Rory Burford: "When you think of climate change and glaciers, you probably think of melting. But in the Peruvian Andes, that's only half the problem. My PhD project looks at why the rivers are turning acidic and filling up with toxic heavy metals." https://www.youtube.com/watch?v=kfhMKWswnvI#Peru#Andes#Glaciers#Cryosphere#ClimateChange
#Swiss#glaciers lose 10% of their volume in two years
Volume lost during hot summers of 2022 and 2023 equal to total depletion between 1960 and 1990, says report
Glaciers in Switzerland are disappearing at a “mind-blowing” pace, the Swiss Academy of Sciences says. In just two years, the glaciers have shrunk 10%, the same amount of ice loss experienced over the three-decade period between 1960 and 1990. Matthias Huss, head of the Swiss Glacier Monitoring Network, says this acceleration “would have been impossible without climate change.”
In 1879, at the 2nd international meteorological congress, the precursor organisation of the WMO suggested it would be useful for the future to measure the lengths and thicknesses of the world's #glaciers.
The Swiss #glaciers have lost 10% of their volume in just 2 years, due to unusually hot summers and winters with very low snow volume.
The rate at which small glaciers are melting is alarming. Even with global warming limited to 1.5oC, #Switzerland 's glacier volume is expected to be only a third of what it currently is. This highlights the severity of the #ClimateCrisis and the need for immediate action to mitigate its impact.

The biggest decline since measurements began was seen in 2022, followed by the second biggest this year, the Swiss Academy of Sciences and Glacier Monitoring Switzerland announced today.
Record low Antarctic sea ice coverage indicates a new sea ice state
"Here, we show the confluence of Southern Ocean subsurface warming & record minima and suggest that ocean warming has played a role in pushing Antarctic sea ice into a new low-extent state. In addition, this new state exhibits different seasonal persistence characteristics, suggesting that the underlying processes controlling Antarctic sea ice coverage may have altered." https://www.nature.com/articles/s43247-023-00961-9 #Antarctic#SeaIce#Glaciers
New website that will capture high resolution pictures of Piz Palü and Pers-Gletscher in Switzerland every 30 seconds for the next 10 years. Goal is to raise further awareness of consequences of global warming. The pictures are also used by glaciologists to use in their studies.
The CBC has a long form report on the eventual end of the Peyto Glacier in Alberta's Glacier Parkway. This is the reference glacier for this beautiful area, but it is rapidly melting in a warming climate. The water from the glaciers in the Glacier Parkway acts as a reservoir for Alberta, and if they are gone, it is a big problem. #ClimateChange#Glaciershttps://www.cbc.ca/newsinteractives/features/the-canary-in-the-icefield
"Scientists have tracked the fate of the Peyto Glacier in the Rocky Mountains for decades as a global reference point. It’s disappearing faster than expected — a warning sign for communities downstream."
Après des décennies de pratique des sciences de l'#Antarctique, j'ai appris que les changements physiques et biologiques se font rarement en douceur. Le #climat et les #écosystèmes de l'Antarctique subissent à l'heure actuelle des changements inquiétants.
Cet hiver, une grande partie de la glace de mer a disparu. Un courant océanique crucial ralentit, et les #glaciers et les plates-formes de glace se désintègrent.
