    Kdybychom touto cestou chtěli – byť s pomocí obnovitelných zdrojů energie - odstranit z atmosféry jednu jedinou gigatunu CO2, tedy čtyřicetinu našeho globálního problému, museli bychom využít dvounásobek solární a větrné energie než kolik momentálně máme celosvětově k dispozici.“

    Your pee could be the golden ticket to a greener world | Popular Science
    https://www.popsci.com/story/environment/human-pee-as-fertilizer/

    At the Rich Earth Institute in Vermont, researchers have been collecting urine from nearby residents and running field trials. The institute is tapped into a community network, where about 200 people contribute with the help of special toilets that separate urine from poo. In tests comparing urine, synthetic fertilizer, and no-fertilizer controls, they’ve found no difference in yields from hay fields fertilized with pee and conventional fertilizer.  “[Urine recycling]’s addressing two problems at once,” says research director Abraham Noe-Hays: wastewater’s surplus of pee and agriculture’s need for nitrogen. “And it’s a circular economy when you’re reclaiming urine, because what you used to think of as waste is now actually the raw material.”

    “…One of the penalties of an ecological education is that one lives alone in a world of wounds. Much of the damage inflicted on land is quite invisible to laymen. An ecologist must either harden his shell and make believe that the consequences of science are none of his business, or he must be the the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise…”

    Reaching UK net zero target cheaper than we thought, says climate adviser | Environment | The Guardian
    https://www.theguardian.com/...ching-uk-net-zero-target-cheaper-than-we-thought-says-climate-adviser

    When the Climate Change Act was passed in the UK in 2008, the government estimated that the cost of meeting its then target of an 80% reduction in emissions by 2050 would be about 2% of GDP over that period. Now, the costs are expected to be well below that, and likely to fall further.

    “I don’t particularly see problems [in decarbonising the economy] – what I see is an absence of a plan,” he told the Guardian. “We have to get to the point by about the start of the next decade where all new investments, every new car, every new van, every new boiler, every new bit of plant and machinery for a business – that needs to be zero carbon by then, or at least have a plan in place to become zero carbon. The biggest challenge that I see at the moment is that we haven’t got a plan that looks anything like that for the UK at the moment.”

    In some sectors, moving to zero carbon will represent a cost saving. Electric cars, for instance, will be cheaper to run than petrol or diesel vehicles. Eventually, the same is likely to be true of low-carbon domestic heating, after the cost of switching. But until now, the main mechanism for paying for the move to a low-carbon economy has been additions to energy bills, which fall disproportionately on poorer people.

    Vědci zkoumají, jak a proč umírají stromy v Amazonském pralese. Zdá se, že je to důležité - Ekolist.cz
    https://ekolist.cz/...oumaji-jak-a-proc-umiraji-stromy-v-amazonskem-pralese.zda-se-ze-je-to-dulezite

    Podle zjištění studie se zdá, že klimatická změna favorizuje především rychle rostoucí druhy stromů. Zároveň ale dochází k tomu, že tyto druhy odumírají v mladším věku. „Tím, že mají rychle rostoucí druhy stromů kratší životní cyklus, klesá schopnost celého lesa ukládat uhlík,“ vysvětluje David Galbraith z univerzity v Leedsu.

    US Emissions to Drop 9% in 2020, Putting Country Back on Track for Paris Commitment | Greentech Media
    https://www.greentechmedia.com/...-drop-9-in-2020-putting-country-back-on-track-for-paris-commitment

    It's a sign of the impact that COVID-19 shutdowns and the ensuing recession have had on life in the U.S. When workers stayed home and the streets emptied out, it reduced emissions from transportation, which accounted for the largest decline at 4 percent of economywide emissions. The power sector drove another 2.8 percent decline, while reduced industrial activity lowered emissions by another 1.6 percent.

    The drastic reduction in planet-warming emissions did not result from concerted action on climate change, so much as an unprecedented and deadly pandemic. Without the COVID-19 crisis, the U.S. would have released just 1 percent less carbon than in 2019, BNEF estimated. The mandated cessation of activities to stop the spread of coronavirus led to the additional reduction of 8 percent.

    Fishing saps the ocean's power to capture carbon - Futurity
    https://www.futurity.org/fishing-carbon-sequestration-oceans-climate-change-2474942/

    Fishing reduces carbon sequestration in the ocean, researchers report.

    A fish that dies naturally in the ocean sinks to the depths, taking with it all the carbon it contains. Yet, when a fish is caught, most of this carbon is released into the atmosphere as CO2.

    The researchers estimate that because of this overlooked phenomenon, carbon emissions from fishing are actually 25% higher than what, until now, was considered to come from fuel consumption alone.

    LINKOS: to už jsou dneska taky stále více ledky :) Tam, kde se rekonstruuje VO, vidis ledky skoro vsude, vcetne kdejake Horni Dolni u Lhotky ..

    U toho pesteni pod svetlama bych hlavni vyhodu videl v obrovske uspore vody, protoze v celem retezci je mnohem min potreba myti a zavlazovani, a odpar, voda se proste spotrebuje temer vsechna.
    Dalsi bude doprava, ktera se smrskne na posilani seminek od Monsanta (coz je taky zlo). Plus vsechny ty traktory .. misto toho bude mechanizace resena elekto
    A nakonec plocha, pole nemuzes hnat do stoku. Tohle jo.

    Mozna je to dalsi krok od 'roste to samo' pres 'zaleju pole chemkou a ono to roste jako z prirucky' po tohle uplne technicky pestovani. Redefinice vidlaka :)

    XCHAOS: Toť otázka, skleněný strop je mizerný izolant v zimě a energetické náklady na vytápění budou rozhodně větší, než náklady na svícení, navíc spousta obchoďáků přechází na ledky. V létě jsou pak tyhle obchoďáky draze klimatizovaný, opět ztráty skrze skleněný strop, sic zastínění aspoň redukuje solární zisky, které jsou u skleněného stropu v létě přímo brutální.
