Swiss Glaciers Lose 10% of Their Volume in Two Years (theguardian.com) 65

Swiss glaciers have lost 10% of their volume in just two years, a report has found. From a report: Scientists have said climate breakdown caused by the burning of fossil fuels is the cause of unusually hot summers and winters with very low snow volume, which have caused the accelerating melts. The volume lost during the hot summers of 2022 and 2023 is the same as that lost between 1960 and 1990. The analysis by the Swiss Academy of Sciences found 4% of Switzerland's total glacier volume vanished this year, the second-biggest annual decline on record. The largest decline was in 2022, when there was a 6% drop, the biggest thaw since measurements began. Experts have stopped measuring the ice on some glaciers as there is essentially none left. Glacier Monitoring in Switzerland (Glamos), which monitors 176 glaciers, recently halted measurements at the St Annafirn glacier in the central Swiss canton of Uri since it had mostly melted.

Swiss Glaciers Lose 10% of Their Volume in Two Years

  • Time for the locals to start looking into expanded reservoirs, assuming that their yearly rainfall still allows them to make up for the deficit. Some places rely on yearly glacier melt as a water supply for agriculture etc.

      I don't really know much about agriculture in Switzerland, but it's not like California where snow melt derived irrigation allows the desert to be turned into productive farmland. Some quick googling tells me that Switzerland's agriculture happens mostly in a relatively temperate area that receives plenty of rain, kind of like the productive farmland of the Midwest. Another quick google told me that 8% of Swiss water goes to agriculture, while 80% of American water goes to agriculture.

        Over 90% of California water goes to agriculture. Takes a lot of water to farm water heavy crops in a desert.

          Okay look. I hate California like the next person. Especially San Fransisco. But we've got to fucking stop this shit of "California = desert". The Köppen climate classification puts the majority of California as either Hot-summer Mediterranean (Csa) to Warm-summer Mediterranean (Csb) which are ideal conditions for growing many of the types of food they grow. Most of California is NOT a desert. San Bernardino County (20057 sq mi), Riverside County(7206 sq mi), Imperial County(4482 sq mi), and Inyo County(10181 sq mi) are pretty much it for parts of California that are "technically" a desert, out of the 155,959 square miles of land in California. Meaning that about 27% of California is what one would technically call desert and the vast majority of it, around 70%, being some combination of Mediterranean. The remainder is between Dry-Summer Subarctic (Dsc) and Tundra (ET) classification and sprinkles of Oceanic (Cfb) and Warm-summer Mediterranean continental (Dsb) classifications.

          California crosses a lot of latitude, there's a lot of various climate in the State and there are states that have WAY MORE land in technical classifications of desert than California.

          Now that said. Should they be growing some of the plants they do out there? Probably not, but if we weren't growing it there, we'd be getting it from Mexico so pick your poison I guess. However, the way we do food in the United States to begin with is insane everywhere, so I mean California is just the easiest to pick on but everyone is farming pretty unsustainable. Too much food is not grown local and that's a major problem with modern industrial farming.

            Yes, it's a big state, so?

            The huge central part where they farm all the water (and other) crops would be dry as a fucking bone if they didn't pour a zillion gallons of water on it every day.

            California would be a mass food importer, not exporter without that huge water expense. It's just math. It has nothing to do with hating or loving California.

          • If you overlay a rainfall map for California with a satellite image of the state, you'll see that where the rainfall map says there's 10 inches of rain each year, the satellite map shows green fields. Even some more northern parts of the Central Valley receive adequate rainfall for some agriculture, but the rain doesn't fall during the summertime, which again necessitates heavy irrigation to grow the kinds of fruits and vegetables that are produced there. I don't think anyone is claiming that California i

    I think it's still a point the "general public" doesn't understand at all, that glaciers aren't just made of ice.

    "Experts have stopped measuring the ice on some glaciers as there is essentially none left."

    If all the ice melts off of a glacier, it's likely to still be a huge structure made of rock and sediment, with a lot of trapped water within all of that.

    I think most people envision glaciers as made entirely of ice, and think climate change is causing these to completely melt down to nothing, created huge floods of water. (And honestly, I can't help but feel like the climate change activists are encouraging that false understanding because it creates more fear.)

      In reality, when the glaciers are gone, the rivers and meltwater in the spring and summer cease, which will drastically change biomes. The rich grassland can easily turn into brown savanna or less productive uses. Forests wilt and become vulnerable to forest fires.

      Glaciers are a good thing, as they provide useful water, and if they melt completely, it also hastens soil erosion.

      Plus this is Switzerland we are talking about, one of the few countries that is considered the pinnacle of civilization and human welfare. Other countries can turn to desert, and it may not matter to them, but Switzerland is a wonder of the world.

          Actually that hasn't been the case for decades. The US is the world's largest money laundry by far, we process well over a Trillion (yes, with a T) dollars in dirty money every year, half of it from drugs and the rest from the whole laundry list of fraud, weapons sales, tax evasion, etc. The large money laundries like CitiCorp and First Boston charge 10-15% in fees for largely automatic transactions which may cascade cash through half a dozen countries in a few minutes. $1 Trillion * 10% = $100 billion in almost pure profit every year. This more than any other reason is why drug policy in the US is so fucked up, the financial industry loves the situation and they ensure that their pet congresscritters maintain the status quo.

      • The glaciers are gone from Wisconsin, but is still plenty of melt water every spring. There was no rich grassland until after the glaciers departed, and the forest moved in after that.

        Now in Nevada, Lake Lahontan did dry up after the glaciers retreated. The salt flats that were left behind really didn't grow anything, but limited forests grew on the mountains that were tall enough to scrape some water from the sky. And since it snows in the mountains there is meltwater in the spring.

      The NSIDC reckons that a glacier is an accumulation of ice and snow that slowly flows over land.
