    Meta & Fysikken: Afsnit 114: Klima-status.
    2025/10/31
    Vi tager lige en status på klimaet, her Oktober 2025.1: Ocean Warming2: Koralrev3:Tipping Points4: Permafrost i Rusland5: Hvad gør vi med den CO2 vi indfanger?6: Fuel Cells / Green Hydrogen plant7: Kelp Farming in Norway------------------------------------------------1 : Ocean warming : https://www.sciencealert.com/ocean-warming-threatens-microbe-that-makes-nearly-a-third-of-earths-oxygenJeff Berardelli (meterolog USA):It's hard to overstate just how off the charts warm the Pacific is right now. The swath of the basin from California to Japan (a HUGE area) from 25N to 60N is ~3F (1.6C) above normal. To put it into math terms that is 6 Sigma/ standard deviations above the mean. I won't bother calculating the chances of this happening against the late 20th century climate - let alone the pre-industrial climate - because the numbers would show it simply could never happen without global warming.So let's talk about why this is happening. Since the last El Nino a couple of years ago the ocean has been rearranging its warm/cool water, as it typically does as a normal part of it's natural oscillation. (This summer a record ridge/ heat dome was parked over the N Pacific).But each next time this configuration lines up (warm north Pacific/ cool tropical Pacific) it piles on a higher and higher baseline temperature over time due to greenhouse warming, air pollution reduction, and the feedbacks (clouds & direct insolation) of both. So we end up with the bottom chart which shows the standardized anomaly (departure from normal) is sloping upward at a very unnatural and alarming rate.2: Koralrevhttps://www.dr.dk/nyheder/viden/klima/ny-rapport-det-er-saa-godt-som-uundgaaeligt-verdens-koralrev-kollapserhttps://videnskab.dk/naturvidenskab/oejenaabner-genopretning-af-koraller-kan-ikke-redde-verdens-rev/3: Tipping Pointshttps://videnskab.dk/naturvidenskab/tipping-points-lyder-skraemmende-men-der-er-haab-endnu/4: Permafrost i Rusland:https://videnskab.dk/naturvidenskab/klimabombe-i-rusland-danske-forskere-advarer-om-alvorlig-mangel-paa-videnOgså:Eksploderende Methan gas i Siberien:https://www.sciencealert.com/mysterious-giant-exploding-craters-in-siberia-may-finally-be-explained5:Hvad gør vi med den CO2 vi indfangerhttps://videnskab.dk/teknologi/hvad-goer-vi-med-den-co2-vi-fanger/Vi sender noget af den tilbage til oliefelterne vi har tømt i de danske farvande. Kilde: Royalt halløj----------------------------6: Tysklands største Hydrogen fabrik:Germany's largest commercial renewable hydrogen factory is the 10 MW plant in Schwäbisch Gmünd, opened by Lhyfe in October 2025. The facility can produce up to 4 tons of renewable hydrogen per day and is Lhyfe's largest outside of France. While it's the largest operational commercial plant, there are larger-scale projects planned for the future in Germany, such as a 130 MW plant planned for Prenzlau by ENERTRAG. https://engineerine.com/largest-green-hydrogen-plant/https://www.lhyfe.com/press/lhyfe-inaugurates-germanys-largest-commercial-renewable-hydrogen-production-site-in-baden-wurttemberg-to-distribute-rfnbo-certified-hydrogen-to-a-range-of-players/A green hydrogen factory is good for the climate because it can be produced using renewable energy, with zero greenhouse gas emissions, and can replace fossil fuels in sectors that are hard to electrify, like heavy industry. When used in a fuel cell, hydrogen only releases water vapor and warm air, making it a clean energy carrier that can also store and deliver renewable energy. #Hydrogen Fuel Cell makes electricity directly. They also produce water vapor, heat and, depending on the fuel source, very small amounts of nitrogen dioxide and other emissions.-------------------------7: Kelp farming in Norwayhttps://www.dnv.com/news/2024/new-seaweed-farm-off-the-norwegian-coast-seeks-to-remove-co2-from-the-atmosphere-252006/--------------------------------8: State of Climate Action 2025:https://www.wri.org/research/state-climate-action-2025" It finds that recent progress toward 1.5°C-aligned targets has largely failed to materialize at the required pace and scale and highlights where action must accelerate this decade to reduce greenhouse gas emissions, scale up carbon removal and increase climate finance."" Although more than three-quarters of indicators are heading in the right direction, progress is alarmingly inadequate, exposing communities, economies and ecosystems to unacceptable risks. Global efforts across 29 indicators are “well off track,” such that at least a twofold—and for most, more than a fourfold—acceleration will be required this decade to keep the 1.5°C limit within reach. "Getting on track for 2030 and staying on track for 2035 demands an enormous acceleration of efforts across every sector. The world must, for example:Phase out coal more than ten times faster — equivalent to retiring nearly 360 average-sized coal-fired power plants each year and halting all projects in the pipeline.Reduce ...

    Meta & Fysikken: Afsnit 113: Deep State! Hvor ender vores personlige data egentlig henne?
    2025/10/24

    Idag tager vi et langt og “unscripted” tilløb til lidt om kometer, som var det vi egentlig havde forberedt. Men vi kom igang ude på et helt andet spor. Så hvis du sidder og KUN er interesseret i det om kometer, så kan du skippe frem til 33:50, hvor vi kommer ind på kometer på nattehimlen.

    Inden da taler vi om Karina’s ansøgning om tysk statsborgerskab, de oplysninger myndighederne kræver, hvor mon disse oplysninger ender henne? - og vi kommer ind på Deep State og masseovervågning i det hele taget.

    Her er Karinas forberedte noter til dagens afsnit:

    Meta & Fysikken: Afsnit 112: Hvad sker der på Mars for tiden? Og hvad med NASA?
    2025/10/17
    I dette afsnit taler vi om de nyeste opdagelser på Mars. Man har set leopard-prikker. Disse prikker kan normalt være tegn på mikroskopisk liv, eller ihvertfald tegn på at der har været liv. I en eller anden form…Og så er NASA underlagt kyniske besparelser, hvis disse gennemføres i den amerikanske kongres. Hvilken betydning får dette eventuelt?Her er Karina’s noter til dagens afsnit.liv på Mars:https://www.nasa.gov/news-release/nasa-says-mars-rover-discovered-potential-biosignature-last-year/Perseverence rover er placeret i en udtørret flod, fordi man mente at der der ville være størst chance for at finde tegn på liv. Se billedet af leopardpletterne. Der har man fundet organisk kemi (carbon / Oxygen / Hydrogen forbindelser) og mineraler (Jern og Sulfat), som her på Jorden har en mikrobiologisk oprindelse. Andre ikke biologiske processer der kunne lave disse mineraler:-Høj temperatur. Men de kemiske analyser viser at dette er/var et lav temperatur miljø-Syre baseret miljø, men det tyder det ikke på at det var fra de andre kemiske ting.Den bedste forklaring er lige nu at det er biologisk oprindelse, som er omkring fire milliarder år gamle.Videnskabelig artikel lægger op til diskussion:»Men fordi det er på Mars, hvor der jo ikke kendes liv i dag, kan vi ikke med 100 procent sikkerhed sige, at dette er et bevis på tidligere liv på Mars. Men vi kan sige, at vi ikke har kunnet finde andre forklaringer på vores data, end at der har været liv på Mars,«Vi vil gerne have prøver tilbage til Jorden for at analysere. Kan der være liv på Mars i dag? Måske har det udviklet sig efter forholdene eller gravet sig ned til bedre forhold da overfladen på Mars blev for barsk.En anden artikel fra 2023 om fund a carbon molekyler. https://www.sciencealert.com/scientists-detect-intriguing-new-signals-of-organic-molecules-on-mars----------------------------------------Er Mars geologisk gold?https://www.sciencealert.com/colossal-discovery-on-mars-could-drive-surging-magma-under-the-surfaceMars has shown very convincing signs of being geologically dead, inside and out. Its relatively old surface – seeming to lack recent volcanic resurfacing and tectonic motion – and absence of a global magnetic field have been held up as reasons to think there's little else but firm, motionless rock all the way down to the core.Recent observations have poked significant holes in the notion of a completely dead Mars. There was a meteorite from Mars that made its way to Earth that showed signs of mantle convection as recently as around half a billion years ago for example.Then satellite photos revealed evidence of volcanic surface deposits as young as 50,000 years old in a fissure system called the Cerberus Fossae.And then Mars InSight, a lander monitoring the Mars interior since November 2018, revealed significant ongoing seismic activity consistent with volcanism.There have been a few other odd observations. The local gravity field of the Elysium Planitia, for example, is unusually strong, consistent with some sort of subsurface activity.Så der er mulgivis magma / flydende sten under overfladen.-------------------------------------------Lad os få et overblik over NASA's Mars aktivitet:https://science.nasa.gov/planetary-science/programs/mars-exploration/Last thing to land was Perserverence, which was in 30.07.2020 (5 years!)----------------------------------------------https://videnskab.dk/rummet/10-ting-du-ikke-vidste-om-mars/1.
