'Zero-Degree Line' Rises To Record Height As Heatwave Continues In Europe 75

Switzerland's MeteoSuisse reported another measure of record summer heat Monday when its weather balloon climbed to a record-high 17,400 feet before reaching what it calls the zero-degree line. UPI reports: The zero-degree line, which is the altitude at which the temperature falls below freezing, is considered a key meteorological marker, particularly in mountainous regions, has been climbing and set a record in 2022. "The Payerne, [Switzerland] radiosounding this night from August 20 to 21, 2023 measured the 0C isothermal 5,298 meters, which is a record since the start of measurements in 1954," MeteoSuisse said in a translated social media post.

The weather service said the zero-degree line "affects vegetation, the snow line and the water cycle so has a considerable impact on the habitats of humans, animals and plants alike." The zero-degree line averaged 8,432 feet from 1991 to 2020, with a high of about 13,123 feet in the summer. "Anthropogenic climate change has caused the altitude of the zero-degree line to rise significantly in every season," MeteoSuisse said.

      Although your comment has little to do with TFA, it is also just wrong. Maybe check actual data before posting?

      The actual data on Switzerland's energy [admin.ch] shows that electricity production is 62% hydroelectric and 29% nuclear. Total energy usage (including cars, etc.) obviously includes more fossil fuels, 36.3% of our total energy usage. Oil is imported, since we have no oil of our own: 39% from Nigeria, 32% from the USA and 25% from Libya.

      You, of course, are from the USA. Where 26% of your electricity comes from coal.

      • Ah my mistake, I see there are different numbers for consumption vs. production, I missed that when I look at my source: https://ourworldindata.org/ene... [ourworldindata.org] where it's far less clear than yours.

        The thing is, you're both right. Energy, in all its forms, is 49.1% oil and gas from yor own figures (36.3% oil and 12.8% gas). Electricity, aka "power", is of course much greener.

        This basically goes to show how unbelieveably addicted we are to fossil fuels as a planet.

        Even a country with an electricity grid as green as Switzerland's still has at least half of its energy coming from fossil fuels (I'm not sure what's in the 17% of "Other").

        The planet doesn't care whether this was imported, produced domestically, burned in a car, or burned in a power station. It's all the same carbon dioxide.

        This is all well and good, but Global Warming is worldwide, thus the word "global" :). Many places have done nothing but increase the use of fossil fuels.

        So in a way the parent post is correct. The US just opened 2 more oil drilling sites, this is under the "environment president". If the GOP was in charge maybe it would have been 3 instead of 2. Also the politicians in the US is doing all they can to keep Gas Prices Low. Why, to get re-elected. So nothing will be done in many places until the politicians "take one for the team".

        So yes, keep burning oil. So how to change, stop subsidizing the Oil Industry, then you will see people move quickly to renewals.

    Well if the Gulf Stream shuts down that'll cool things off quickly there.

        • According to this [arstechnica.com] the climate with the Gulf Stream gone wouldn't really be what I'd call acceptable. 3.4 degree drop is pretty bad but the loss of almost 80% of all arable land in UK would be the one that really hurt. The study doesn't look at what would happen in northern continental Europe, but I imagine it wouldn't be good either.

          No, it's what our political system is built on. In the US at least, there's a huge portion of the population that wants to concentrate money in the smallest number of hands (i.e. the federal government) in the hopes that your "team" will be able to impose its will on the other "team".

        China is about 5 years ahead of its agreed Paris target for peaking emissions. Should be around 2025-26. The peak will be about half what the average American emits, and then start falling.

        That is incredibly good news because the planet couldn't take another 1.4 billion people living an American lifestyle. Or even a European one, for that matter. If China can do it and still maintain improving quality of life for citizens, then so can India and Brazil and all the other developing nations.

          • by HiThere ( 15173 )

            Sorry, but everything he mentioned has an effect, generally warming, on the weather. Most of them are quite minor, but he was hypothesizing a "perfect storm", which sort of implies lots of small things piling on top of the major causes. So it's a plausible guess, but I don't think any model could validate it.

            OTOH, "perfect storm"s happen occasionally, and need to be expected to happen occasionally. This isn't an argument that things aren't extremely bad, but may be an explanation for why they were worse

            • Maybe this time it didn't act as usual, but that's not something to assume

              If you google around, you'll see that the Tongan eruption was exactly that--few sulfur aerosols, lots of water vapor. Totally the opposite of Pinatubo. Last I saw, its warming impact was mostly for the Southern Hemisphere, and was expected to clear in a few years.

                It's a bigger water vapour increase, over a sustained period, than I had understood so yes, that would be a rare case of a volcanic eruption having a warming effect. Normally it only applies to activity short of an eruption which can include CO2 leakage but at a level well within the capability of natural carbon sinks to handle, Deccan Traps, etc., excepted.

              Sorry, but everything he mentioned has an effect, generally warming, on the weather.

              Typically, volcanic eruptions put out CO2 but also other things, noticeably particulates, and typically result in cooling, as you note. This is almost always the case.

              Most of them are quite minor

              Solar activity changes are so tiny that they have not been discerned to have any effect at all.

                Well, I've seen studies that said they thought they had some effect, but then I've seen the same about variation in cosmic ray intensity. (Something about ionizing upper layers of the atmosphere, but I never got clear on what.)

                  I haven't seen any paper that has stood up to long term scrutiny that has suggested any meaningful effect. The variations in insolation is incredibly tiny. Cosmic rays - also nothing credible I've seen. About fifteen years ago proponents of such theories assured us we'd now be in a period of cooling because of such effects and it hasn't happened. Even now they crop up. If I see credible evidence I'll change my mind but over the last fifty years the conventional theories regarding climate change have proven
            • OTOH, "perfect storm"s happen occasionally, and need to be expected to happen occasionally.

              In probabilistic terms, "occasionally" does not mean anything. What means something is stuff like Antartic ice levels nosediving in a five-sigma event [abc.net.au]. What is a five-sigma event you might ask? It is something that is likely to happen once every 7.5 million year. So you can think that we hit the jackpot this year. But the likely explanation is that it is not a "perfect storm", but just a direct result of the amount of CO2 we keep emitting in excess.

        Or, if we follow the Occam's razor principle [wikipedia.org], the simplest explanation is the amount of CO2 we emit in excess compared to pre-industrial levels. Maybe it is a coïncidence, but this is the explanation favored by actual scientists. Go figure.

        It is a legitimate question: "Why is this year hotter than the models expected?". This doesn't mean one can expect an immediate answer.

        • by gweihir ( 88907 )

          The models are longer-term averages. The models also predict significantly larger variation than before. Is there really anybody left (except the deniers) that does not know these basic facts?

        • It is a legitimate question: "Why is this year hotter than the models expected?".

          It is not.

          The models do not predict specific events, they show trends. The high temperatures are within the error bars of the trend lines -aka, within the range of predicted results.

          • To clarify my reply....

            I am not saying the question is not legitimate.
            I am saying the answer to the question is that the temperature is not outside the predicted results.

            • by HiThere ( 15173 )

              Yeah, but the predicted results have pretty wide error bars. When you get a result near the edge of what your model predicts, you need to look for some factor you didn't include that you should.

              P.S.: We KNOW that there are lots of important factors not included. Most climate models don't include the ocean around Antarctica, and that's a major issue.
