    Internetem v posledních dnech kolují fotky ze San Francisca, kde se vlivem lesních požárů obloha změnila z modré na oranžovou. Opravdu to na místě vypadá jako na fotkách?

    Ano. A není to záležitost jen několika posledních dní. Požáry tady začaly už někdy na začátku srpna, což všechny strašně překvapilo. Lidé se totiž připravují hlavně na podzim, protože nejhorší to bývá v říjnu a listopadu. Všechny nás šokoval také rozsah požárů, protože je to všude okolo a v těsné blízkosti města.

    Nejhorší situace byla teď v úterý, kdy jsem se vzbudila a ze závěsů na mě prosvítala oranžová barva. Vůbec jsem nechápala, co se děje. Připadalo mi to trochu jako pouštní bouře, kterou jsem zažila jednou v Tel Avivu. Vzduch byl relativně dobrý, protože znečištění se drželo hodně nahoře, jen celý den byla tma. Ve středu ale kouř spadl dolů a kvalita ovzduší začala být hrozná.

    Co se týče vzduchu, tak hodně záleží na tom, odkud fouká vítr. Když od oceánu, tak je to dobré, protože většinu kouře rozfouká. Když od jihu nebo severu, tak je to hodně špatné. Nyní se to zase začíná zhoršovat. Před chvílí jsme byli v obchodě a auta jsou úplně posetá popelem. A nedá se pořádně dýchat.

    SHEFIK: Proč je efektivita překážkou, když v létě budeme mít přebytky z OZE - elektřinu zadarmo? Není problém spíš chybějící infrastruktura a odpor fosilního průmyslu?

    Moria migrants: Fire destroys Greek camp leaving 13,000 without shelter
    https://www.bbc.com/news/world-europe-54082201

    Police blocked roads from the camp to prevent migrants entering nearby towns.

    Many attempted to carry their belongings to the port town of Mytilene but access was cordoned off. Reports suggest many slept in fields after the fire.

    Some locals reportedly attacked and prevented migrants from passing through a nearby village after they fled the flames.

    "We don't know where to go, and all the refugees are outside, and trying to find a place to at least just stay," he said.

    Quantifying national responsibility for climate breakdown: an equality-based attribution approach for carbon dioxide emissions in excess of the planetary boundary
    https://www.sciencedirect.com/science/article/pii/S2542519620301960

    This analysis proposes a novel method for quantifying national responsibility for damages related to climate change by looking at national contributions to cumulative CO2 emissions in excess of the planetary boundary of 350 ppm atmospheric CO2 concentration. This approach is rooted in the principle of equal per capita access to atmospheric commons.

    KEB: co jsem se bavil ve vedeckym auditku, tak prave ten cpavek apod. je lepsi, jak na skladovani, tak distribuci. dokonce sem tam linkoval studii, kde chtej levne vyrabet cpavek a pak konvertovat na vodik v pripade potreby :)

    vodik je imho prave kvuli tomu co sem napsal niz (hustota/energie/vykon)

    dalsim duvodem pak muzou bejt derivaty dalsich produktu, jako hnojiva atd.

    v tomhle mam zatim mezery

    SHEFIK: proč se pořád řeší vodík, který skladovat je problém, ale nezkouší se jít cestou čpavku? Je to jen kvůli toxicitě nebo to má o jiný důvod? Nevíš?

    XCHAOS: no tech power to gas/liquid reseni je vic. taky jsou redox flow baterky na velky kapacity.

    vodik v sobe ale ma obrovskej power, takze je idealni do prumyslu, letecky, lodni dopravy apod.

    prekazkou na masovy pouziti je uz jen efektivita konverze a na tom spousta lidi pracuje. nedavno sem sem nebo do vedeckyho auditka daval link na novou membranu s daleko vyssi ucinnosti

    SHEFIK: jo, no to zato my jsme pašáci, my snižujeme spotřební daň na naftu :-)

    "vodíkové ekonomice" ve smyslu těch vlaků a náklaďáků - teda moc nevěřím, tam prostě převládnou baterie, i kvůli rekuperaci. Ale stacionární úložiště vodíku asi smysl dává, je to v podstatě jediné sezónní úložiště, které umíme (je tam spousta odpadního tepla, z těch palivových článků, takže by to dávalo smysl jako náhrada uhelných elektráren, s využitím existujících teplovodů)

    Wildfires blazed along the Arctic Circle this summer, incinerating tundra, blanketing Siberian cities in smoke and capping the second extraordinary fire season in a row. By the time the fire season waned at the end of last month, the blazes had emitted a record 244 megatonnes of carbon dioxide — that’s 35% more than last year, which also set records. One culprit, scientists say, could be peatlands that are burning as the top of the world melts.

    Peatlands are carbon-rich soils that accumulate as waterlogged plants slowly decay, sometimes over thousands of years. They are the most carbon-dense ecosystems on Earth; a typical northern peatland packs in roughly ten times as much carbon as a boreal forest. When peat burns, it releases its ancient carbon to the atmosphere, adding to the heat-trapping gases that cause climate change.

    Global Safety Net
    https://www.globalsafetynet.app/

    The first global-scale analysis of land areas requiring protection to solve the twin crises of biodiversity loss and climate change.

    ...

    More than two years in development, the Global Safety Net is the first comprehensive global-scale analysis of terrestrial areas essential for biodiversity and climate resilience, totaling 50.4% of the Earth's land. The report was published in Science Advances and highlights the importance of protecting and restoring the natural world to address three converging crises -- climate change, the loss of biodiversity, and the emergence of novel viruses such as COVID-19.

    The research team was led by the research organization RESOLVE in collaboration with the University of Minnesota, Arizona State University, and Globaïa, with funding provided by One Earth. The data compiled for the Global Safety Net (GSN1) is available through an interactive web application (GSNapp) developed by One Earth in partnership with Google Earth Engine and the data visualization firm Graphicacy. Users can click on a country, state, or ecoregion to see configurations of biologically important land for each region.

    The research effort builds upon an array of global-scale data sets to identify areas that require conservation beyond the 15.1% of land area currently protected. These are compiled into five main layers at a 1 km resolution: Species Rarity Sites, High Biodiversity Areas, Large Mammal Landscapes, Intact Wilderness, and Climate Stabilization Areas.

    Why Poland is finally giving up its dirty coal habit - Electrek
    https://electrek.co/2020/09/10/why-poland-is-finally-giving-up-its-dirty-coal-habit/amp/

    Poland generates a huge 74% of its electricity from coal — second only to Germany in Europe, and it’s the ninth-largest coal producer in the world. It has been the only country in the European Union to refuse to agree to reach net zero by 2050. It claimed it needed more time and money to make the shift.
    But its hand has been forced by the rising costs of emissions permits required by the European Union’s cap-and-trade system, the EU’s other increasingly ambitious climate policies, and the pandemic, which caused a fall in the use of power. Reuters reports:

    In an update of its energy strategy by 2040, the climate ministry said Poland plans to invest 150 billion zlotys ($40 billion) to build its first nuclear power plants, with 6-9 GW of capacity eventually. The first 1-1.6 GW facility would be up and running by 2033.
    It also plans to build 8-11 gigawatts (GW) of offshore wind capacity by 2040 with investment estimated at 130 billion zlotys ($35 billion). The development of renewable and nuclear energy facilities will create 300,000 jobs, it said.

    The climate ministry said that coal’s share in electricity production will fall to 37%-56% in 2030 and to 11-28% in 2040, depending on the carbon emission costs.

    Compare this to November 2019, when Poland had expected the share of coal at 56%-60% in 2030 and at 28% in 2040.

    France wants 6.5 GW of hydrogen capacity by 2030 – pv magazine International
    https://www.pv-magazine.com/2020/09/10/france-wants-6-5-gw-of-hydrogen-capacity-by-2030/

    The ministers reminded their audience the hydrogen strategy has been allocated €7.2 billion to 2030 under the France Relance plan, including €2 billion up to 2022.

    The government defined three hydrogen priorities. Firstly, it wants to decarbonize the industry with a pathway to electrolysis for carbon-free fuel, rather than the generation of hydrogen from fossil fuels. In line with that aim, France will launch an Important Project of Common European Interest for hydrogen similar to the European sustainable battery manufacturing ambition. “This, notably, involves the planning of gigawatt-sized electrolyzer projects in France, according to a scheme similar to the battery plan which provides for the development of the Nersac and Douvrin factories by ACC, a joint venture of [carmaker stable] PSA and [energy company] Total/[and battery subsidiary] Saft (soon to be joined by Renault),” the hydrogen strategy stated.

    The second priority is the development of hydrogen-fueled public transport and commercial goods vehicles – including trains and bin lorries – across large territories. A €350 million tender for innovative projects in that area will be held this year and a €275 million exercise has also been planned to procure ‘innovative large-scale industrial ecosystem’ facilities. The latter, which will attempt to encourage economies of scale, will be conducted by the Environment and Energy Management Agency.
