    Obnovitelné zdroje energie v EU letos ve výrobě elektřiny poprvé překonaly fosilní paliva. V prvním pololetí se z obnovitelných zdrojů vyrobilo 40 procent elektřiny, zatímco fosilní paliva se na její výrobě podílely ze 34 procent. Uvádí to pololetní zpráva nezávislého institutu Ember (odkaz zde). Špinavé zdroje energie jsou kvůli přísnějším ekologickým pravidlům nerentabilní. To nutí vlády a energetické firmy po celé Evropě uzavírat celé doly a uhelné elektrárny. Česká republika je výjimkou.

    The shill, the grifter, the egomaniac and the ideological fool: each distorts the urgent global debate in their own way

    ..

    A sadder case is that of the grifters. They have found themselves earning a living by grinding out contrarian articles for rightwing media outlets. Do they actually believe the guff they write? It doesn’t matter: they just warm their hands on the outrage, count the clicks and wait for the pay cheque.

    The Satanic Gases marshals an impressive array of scientific data, studies, and analyses that argue, cogently and consistently, that the initial forecasts of rapid global warming were simply wrong. But, perhaps more important, the book points out that attempts to “fix” the forecast by the UN’s Intergovernmental Panel on Climate Change are even more misguided than the original projections.

    The authors argue that the jury is already in on global warming, and the verdict is a modest heating over the 21st century—very similar to what occurred during the last third of the 20th century. The vast majority of warming will take place in the winter, and within that season, the coldest, deadliest air masses will show the greatest change. The final third of the last century saw the greatest improvements in food supply, wealth, and longevity of life ever experienced. Some improvements actually resulted from changes in the earth’s natural greenhouse effect and others were totally insensitive to temperature. The authors argue that it is virtually impossible to reverse all of that progress with only a continued slow warming of the planet.

    Unlike every other book on global warming, The Satanic Gases places the issue in its proper social and scientific context. Citing the pioneering work of historian of science Thomas Kuhn and economist James Buchanan, Michaels and Balling demonstrate that it was inevitable that global warming would be distorted by the political sphere and that most scientists would either stand mute or actually assist in that process. But, the authors argue, such distortions in science are always temporary, and inevitably the scientific community will concede that earlier forecasts dramatically exaggerated the threat of global warming.

    Carbon dioxide threatens life in the Gulf of Mexico - Futurity
    https://www.futurity.org/...utm_medium=rss&utm_campaign=gulf-of-mexico-carbon-dioxide-fish-2409192-2

    The amount of carbon dioxide in the atmosphere has increased 40% since the Industrial Revolution (1760 to 1840) because of human activities—and the ocean, including the Gulf of Mexico, has absorbed at least 25% of it. That’s a trend that will almost certainly continue, oceanographers say.

    Boeing has said it will stop making its classic 747 plane and is eyeing steeper job cuts than those it has previously announced.
    The firm is also planning to slow production of many of its jets, including the troubled 737 Max.
    The changes come as the firm disclosed a $2.4bn (£1.8bn) loss as the virus depressed demand for air travel.
    "The reality is the pandemic's impact on the aviation sector continues to be severe," said Boeing boss Dave Calhoun.

    Wind production in Germany and the Netherlands is on the verge of not needing any subsidies, allowing them to be even more competitive than fossil fuel production, which remains heavily subsidized.

    However, due to how subsidies work in the United Kingdom, the team suggest wind energy production here will soon generate “negative subsidies”, with new wind farm projects giving money back to the government, which will be passed on to citizens for cheaper energy bills.

    For most of human history, people have lived within a surprisingly narrow range of temperatures, in the places where the climate supported abundant food production. But as the planet warms, that band is suddenly shifting north. According to a pathbreaking recent study in the journal Proceedings of the National Academy of Sciences, the planet could see a greater temperature increase in the next 50 years than it did in the last 6,000 years combined. By 2070, the kind of extremely hot zones, like in the Sahara, that now cover less than 1 percent of the earth’s land surface could cover nearly a fifth of the land, potentially placing one of every three people alive outside the climate niche where humans have thrived for thousands of years. Many will dig in, suffering through heat, hunger and political chaos, but others will be forced to move on. A 2017 study in Science Advances found that by 2100, temperatures could rise to the point that just going outside for a few hours in some places, including parts of India and Eastern China, “will result in death even for the fittest of humans.”

    Obnova staré zaorané polní cesty v Hlučíně narazila na zemědělce - Ekolist.cz

    Agrozea hospodaří na rozloze větší než 2000 hektarů. Matýsek odhaduje, že obnovením cesty by zemědělci přišli sotva o hektar pronajatých pozemků. Na dotaz, jestli taková ztráta může vést k likvidaci soběstačnosti, odpovídá Josef Fus, že nejde o soběstačnost podniku Agrozea. „Tady nejde o nás, ale o celou Českou republiku. Víte vy vůbec, kolik orné půdy ubude v Čechách ročně? A jenom proto, že to všechno řídí lidi z paneláků?“ ptá se Josef Fus.


    Dokud se tady to agro lobby nepodaří zlomit, tak se nezmzvubec nic.

    TUHO: “We knew the Arctic had increased production in the last few years, but it seemed possible the system was just recycling the same store of nutrients,” Kate Lewis, the lead author, said in a statement released by Stanford. “Our study shows that’s not the case. Phytoplankton are absorbing more carbon year after year as new nutrients come into this ocean. That was unexpected, and it has big ecological impacts.”

    Another study, conducted by scientists at Stanford University and published in the journal Science, tracks found that primary production (the creation of energy, mostly through photosynthesis, that forms the base of food chains), increased by 57 percent between 1998 and 2018 in the Arctic Ocean.

    The study identifies an ongoing regime shift, with thickening amounts of photosynthesizing algae creating much more net biological production.

    The Stanford scientists in the past have examined the link between sea ice retreat and increased phytoplankton-driven production in the Arctic Ocean. That work has included tracking of phytoplankton blooms beneath the ice in the Chukchi Sea and the relationship of ice retreat to phytoplankton blooms in the Bering Sea.

    Now, the Arctic Ocean’s phytoplankton boom is no longer simply a product of more sunlight penetrating through the thinned ice or open waters, the study found. While loss of ice was the big driver of phytoplankton biomass increase during the first decade of the study period, a new factor became dominant in the second decade of the period; inflow of nutrients from the adjoining seas and oceans.

    Europe’s largest solar-storage-hydrogen project – pv magazine International
    https://www.pv-magazine.com/2020/07/28/europes-largest-solar-storage-hydrogen-project/

    Spanish energy company Iberdrola plans to build a 100 MW solar park, a storage facility, and a hydrogen production station in Puertollano, central Spain. The €150 million project is scheduled to be operational next year.

    ...

    The Spanish energy giant will oversee the production of green hydrogen from 100% renewable sources. The solution will consist of a 100 MW solar PV plant, a 20 MWh lithium-ion battery bank, and a 20 MW electrolysis hydrogen production system.

    The green hydrogen produced will be used at a Fertiberia ammonia factory in Puertollano, with a production capacity of more than 200,000 tons per year. Fertiberia will upgrade and modify the plant so it can produce green hydrogen and manufacture green fertilizer.

    The fertilizer supplier will reduce the plant’s natural gas needs by more than 10%. It will be the first European company in the sector to develop experience in the large-scale production of green ammonia.

    Iberdrola said last week that it will build 5.8 GW of renewable energy projects in the years to come. It currently has 7.5 GW of capacity under construction. It has also joined the Choose Renewable Hydrogen initiative, which energy companies are using to urge the European Commission to adopt measures to maximize the potential of green hydrogen

    (...) Carbon Engineering totiž nedávno oznámil, že díky partnerství s americkým petrolejářským gigantem Occidental Petroleum vyvíjí továrnu, která by už v roce 2022 odčerpávala každý rok ze vzduchu milion tun CO2. U její technologie navíc nepředstavuje navyšování kapacity velké komplikace, protože funguje na poměrně jednoduchém principu. Velké turbíny nasávají vzduch a prohání ho přes soustavu lapačů napuštěných chemikálií, která oxid uhličitý zachytává. Nasycený roztok pak putuje do nádrže, kde reakcí s oxidem vápenatým (nehašené vápno) vzniká pevná krystalická látka – uhličitan vápenatý, jinak známý jako vápenec. Ten je pak možné buď ukládat do podzemních úložišť, anebo ho využívat jako surovinu pro výrobu čistého CO2.

    Možná se teď ptáte, proč bychom měli vynakládat tolik úsilí a peněz na zachytávání CO2 ze vzduchu, abychom ho pak znovu uvolňovali. Nic divného na tom však není, protože pro čistý oxid uhličitý máme řadu využití. Mezi největší spotřebitele patří petrochemické koncerny, které ho rády využívají jako hnací plyn pro pumpování ropy z hlubinných vrtů.
    Výhodou tohoto procesu je vysoká účinnost a také fakt, že samotný plyn zůstává uložený pod zemí a vlastně se ho tak zbavujeme.

    DZODZO: no, já tyhle co do kompostu patří/nepatří nemám rád. Tady je to tedy tím, že se bude nejspíše jednat o domácí vermikompost a tam to je trochu jinak.
    Do klasického kompostu patří všechen rozlozitelny odpad. Odpad z kuchyně, tráva, seno, i piliny.
    Samozřejmě všechno to je o úrovni na které se pohybujem, když někdo začíná kompostovat tak prostě je problém si se vším poradit a má smysl tam asi něco z kraje nedávat. Hold ale když už trochu člověk má představu jak se to chová, tak už si může dovolit toho dát tam víc. Ale mnoho hold dělá třeba to, že lidi mají vesměs jen zbytky z kuchyně a zahradní mokrou trávu a to se prostě kompostu je špatně a apk to smrdí a lidi říkají že kompost smrdí atd. Ale to není pravda, ale musíš umět to dobře poskládat. Což ve finále není nic složitého, ale u každé činnosti je potřeba mít nějaký um, know how.
    Dneska kompostuju i liší z oresaku což je prý špatně podle nejednoho- a přitom z toho je naprosto parádní kompost a třeba i psy bobky, i přesto, že mají hrozně smrdet atd. Ale oboje má prostě svoji přihrádku a třeba ten kompost z bobků hold nedám do zeleninového záhonů.
    Pak je ještě vyšší level a tam už se dá na kompost proměnit i to do běžné necháváme na záchodě a splachujem pitnou vodou do řek...

    Jednoduše kompostovat se dá prostě kde co, jen to je o tom mít tu ochotu to dělat a zároveň mít tu znalost jak na to.
