    V porovnaní so stavom globálnej klímy (glob. teploty) zo začiatku minulého roka sme sa po absolútne "šialenom roku" priblížili ku kritickej hranici oteplenia +1,5 °C (K) o celé dva roky. Ak to takto pôjde ďalej, hranicu 1,5C natrvalo presiahneme už niekedy okolo rokov 2027-2029. A ak zoberieme do úvahy prognózy J. Hansena, bude to aj skôr! Držte si klobúky, pôjde to už rýchlo.

    38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change

    Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.

    The Putin Thesis and Russian Energy Policy
    A specialist on Russian politics and society analyzes Russian President Vladimir Putin's academic work on mineral resources in the Russian economy. Mr. Putin defended a kandidat dissertation in economics and subsequently published an article outlining his view of the appropriate role of the Russian state, and of vertically integrated financial-industrial groups, in the mineral resource sector, and particularly in the oil and gas industry. Connections are drawn between the views expressed in Mr. Putin's publications and policy during his second presidential term.

    Energy, climate change and security: The Russian strategic conundrum

    Abstract
    Global and regional energy markets are increasingly influenced by policies aimed at climate change mitigation, with possible grave implications for major producers and exporters of fossil fuels – including Russia, which is planning further increases. This article examines the evolution of Russian official thinking on the role of climate change as a strategic factor in policymaking as expressed in key documents on security and in strategic statements made by Presidents Putin and Medvedev (2000–2020). The set of strategic statements examined in this article show surprisingly little attention to this important matter.

    SCHWEPZ: právě e-paliva a syntetické plyny jsou to co EU škrtla z podpory protože jí to přijde málo zelené.
    Tyhle předsudky je třeba odstranit. Vodík je hezká věc, ale proti syntetickému metanu máte 3x méně přepravené energie teoreticky a kvůli omezením na infrastruktuře 5x méně prakticky.

    To je strašně moc. Nemůžete stáhnout infrastrukturu na pětinu a tvářit se že je všechno v pořádku.

    Sterner používá při výpočtech pro energetickou transformaci primárně právě syngas, který paradoxně je ještě stále odmítán.

    Profesor Michael Sterner je přední německý expert na ukládání energie. Zaměřuje se hlavně na systémy, které umí přebytky získané ze sluneční a větrné elektřiny ukládat do plynu, který se následně využívá jako záloha pro průmysl v době, kdy tolik nefouká nebo nesvítí.

    Věří, že právě tato technologie umožní lidstvu přechod od fosilních paliv a zachrání tak svět před bolestivými dopady klimatických změn:

    World faces ‘deathly silence’ of nature as wildlife disappears, warn experts | Biodiversity | The Guardian
    https://www.theguardian.com/environment/2024/apr/16/world-faces-deathly-silence-of-nature-as-wildlife-disappears-warn-experts-aoe

    Scientists who use ecoacoustics to measure habitats and species say that quiet is falling across thousands of habitats, as the planet witnesses extraordinary losses in the density and variety of species. Disappearing or losing volume along with them are many familiar sounds: the morning calls of birds, rustle of mammals through undergrowth and summer hum of insects.

    Today, tuning into some ecosystems reveals a “deathly silence”, said Prof Steve Simpson from the University of Bristol. “It is that race against time – we’ve only just discovered that they make such sounds, and yet we hear the sound disappearing.”

    “The changes are profound. And they are happening everywhere,” said US soundscape recordist Bernie Krause, who has taken more than 5,000 hours of recordings from seven continents over the past 55 years. He estimates that 70% of his archive is from habitats that no longer exist.

    UK facing food shortages and price rises after extreme weather | Farming | The Guardian
    https://www.theguardian.com/environment/2024/apr/16/uk-facing-food-shortages-and-price-rises-after-extreme-weather

    The UK faces food shortages and price rises as extreme weather linked to climate breakdown causes low yields on farms locally and abroad.

    Record rainfall has meant farmers in many parts of the UK have been unable to plant crops such as potatoes, wheat and vegetables during the key spring season. Crops that have been planted are of poor quality, with some rotting in the ground.

    The persistent wet weather has also meant a high mortality rate for lambs on the UK’s hills, while some dairy cows have been unable to be turned out on to grass, meaning they will produce less milk.

    Agricultural groups have said the UK will be more reliant on imports, but similarly wet conditions in European countries such as France and Germany, as well as drought in Morocco, could mean there is less food to import. Economists have warned this could cause food inflation to rise, meaning higher prices at supermarkets.

    Tom Bradshaw, the president of the National Farmers’ Union, said markets had “collapsed” as farmers fail to produce food in the punishing conditions. He said: “We’re going to be importing a lot more product this year.”

    ...

    France is experiencing the poorest start to its wheat-growing season since 2020 amid cold wet weather, while production of fruit and vegetables in Morocco is being affected by drought. Morocco’s second-largest reservoir has dried up, meaning irrigating crops will be difficult.

    Amber Sawyer, an analyst at the Energy and Climate Intelligence Unit, said last year almost a third of the UK’s tomatoes, and more than two-thirds of its raspberries and brussels sprouts, came from Morocco.

    “As climate change worsens, the threat to our food supply chains – both at home and overseas – will grow,” Sawyer said.

    DZODZO: po troše googlení vladimír gut hospodaří na kambisolech v radošovicích u vlašimi, což jsou in situ dobře provzdušněné půdy s dostatkem živin, kvůli krystlinickým horninám, na kterých se zpravidla vyvíjí.

    naprosto vážně by mě zajímalo, jak moc je regenerativní zemědělství možný provozovat na půdách, kterým hrozí genetické utužení - klesá jim porozita i bez vlivu člověka, oglejením. dál by mě zajímal názor na tento způsob zemědělství od ekozemědělců, kteří docela rádi ořou mělce z důvodu plevelů, škůdců a pod.

    ‘Grownup’ leaders are pushing us towards catastrophe, says former US climate chief | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2024/apr/14/grownup-leaders-are-pushing-us-towards-catastrophe-says-former-us-climate-chief

    “We are slowed down by those who think of themselves as grownups and believe decarbonisation at the speed the climate community calls for is unrealistic,” said Todd Stern, who served as a special envoy for climate change under Barack Obama, and helped negotiate the 2015 Paris agreement.

    “They say that we need to slow down, that what is being proposed [in cuts to greenhouse gas emissions] is unrealistic,” he told the Observer. “You see it a lot in the business world too. It’s really hard [to push for more urgency] because those ‘grownups’ have a lot of influence.”

    NREL Unveils Groundbreaking Generative Machine Learning Model To Simulate Future Energy-Climate Impacts - CleanTechnica
    https://cleantechnica.com/2024/04/10/nrel-unveils-groundbreaking-generative-machine-learning-model-to-simulate-future-energy-climate-impacts/

    Sup3rCC is an open-source model that uses generative machine learning to produce state-of-the-art downscaled future climate data sets that are available to the public at no cost. Downscaled climate data is necessary to understand the impacts of climate change on local wind and solar resources and energy demand. There are a multitude of existing downscaling methods, but they all have trade-offs in resolution, computational costs, and physical constraints in space and time. Sup3rCC represents a new field of generative machine learning methods that can produce physically realistic high-resolution data 40 times faster than traditional dynamical downscaling methods.

    Sup3rCC will change the way we study and plan future energy systems,” said Dan Bilello, director of the Strategic Energy Analysis Center at NREL. “The tool produces foundational climate data that can be plugged into energy system models and provide much-needed insights for decision makers who are responsible for keeping the lights on.”
    ...
    Sup3rCC learns physical characteristics of nature and the atmosphere by studying NREL’s historical high-resolution data sets, including the National Solar Radiation Database and the Wind Integration National Dataset Toolkit. The model then injects physically realistic small-scale information that it has learned from the data sets into the coarse future outputs from global climate models. As a result, Sup3rCC generates highly detailed temperature, humidity, wind speed, and solar irradiance data based on the latest state-of-the-art future climate projections. Sup3rCC outputs can then be used to study future renewable energy power generation, changes in energy demand, and impacts to power system operations. The initial Sup3rCC data set includes data from 2015 to 2059 for the contiguous United States, and additional data sets will be released in the coming years.
