    Scholars believe that the coke reductant within the blast furnace can be replaced by hydrogen, which results in the only emission being water throughout the process that will not lead to any pollution. Hydrogen can also provide electricity for electric arc furnaces, which makes it more possible for a relatively cleaner steelmaking industry to happen. How is the feasibility? Mitsubishi Heavy Industries will be establishing steelmaking equipment that replace coal with hydrogen in Europe, and is currently working with major Austrian steel businesses on developing verification equipment, with operation initiating in 2021 at the earliest.

    Emerging Swedish business H2 Green Steel (H2GS) will also appropriate US$3 billion for steel refining using the hydrogen produced by the renewable energy equipment in Boden-Luleå, and plans to commence production in 2024. H2GS is expected to produce 5 million tons of steel with zero-carbon emission steel by 2030.

    PER2: to jsem zaznamenal, ale nemam kontext techle mereni - merilo se tam predtim a nedelo se to? atp. taky asi napovi vysledky z toho satelitu co jsem sem pred casem daval, kterej ty zdroje ma monitorovat.

    DWD: Zwei-Grad-Ziel nicht mehr zu halten | MDR.DE
    https://www.mdr.de/nachrichten/panorama/dwd-warnt-vor-drastischem-temperatur-anstieg-100.html

    The German Weather Service (DWD) is sounding the alarm: According to the organization, it will no longer be possible to limit global warming to two degrees Celsius by the end of the century. The international community set the two-degree target in the 2015 Paris Climate Agreement . DWD President Gerhard Adrian said at a digital press conference on climate research in Offenbach: "Unfortunately, at the moment it even looks like a plus of three to four degrees." The two-degree target will be missed.

    TADEAS: to se asi "brzo" dozvime

    An international team of oceanographers aboard the Russian research vessel Akademik Keldysh has confirmed a large-scale, ongoing release of methane from the seabed on the East Siberian Arctic Shelf.
    The gas is believed to be released by the melting of subsea permafrost, which in turn allows the release of methane gas from previously-stable methane hydrates. The seabed of the East Siberian Arctic Shelf is unique in that large swaths contain permafrost layers built up some 20-30,000 years ago, when the area was dry land and sea levels were far lower.

    "The discovery of actively releasing shelf slope hydrates is very important and unknown until now,” chief scientist Igor Semiletov told the paper.

    Their results have not yet been peer-reviewed or published, but they represent an extension of previous observations of methane seeps in the same area. In voyages to the region in years past, Semiletov's team has discovered large craters on the seabed emitting significant quantities of methane.

    PER2: video jsem nevidel, ale podporujou to teda nejaky solid studie, ze by slo o akrtickej metan? zatim to bylo minimum, hlavni zdroje ekosystem a ziskavani fosilnich paliv, a hlabne tropicky oblasti.

    Methane Emissions Continue to Rise
    https://earthobservatory.nasa.gov/images/146978/methane-emissions-continue-to-rise

    Across the study years, wetlands contributed 30 percent of global methane emissions, with oil, gas, and coal activities accounting for 20 percent. Agriculture, including enteric fermentation and manure management, made up 24 percent of emissions, and landfills comprised 11 percent. Sixty-four percent of emissions came from tropical regions of South America, Asia, and Africa, with temperate regions accounting for 32 percent and the Arctic contributing 4 percent.

    ...

    High-latitude ecosystems are particularly vulnerable to climate change. Large amounts of carbon are stored in frozen soils (permafrost) and in forest vegetation in the Arctic. As it thaws, water-logged soil becomes an ideal environment for methane production. “However, we have yet to detect abnormal methane emissions in higher-latitude regions,” said Poulter, “despite thawing permafrost and record-breaking air temperatures year-after-year.”

    PER2: chtel jsem naznacit druhy problem: nedostatek pitne vody. Pozary jsou katastrofa, ale po pozaru se lidi vrati, protoze "kdyz to shorelo uz to znova neshori", a odstehuji se az kdyz jim polezou krkem prasne boure, a ze ty budou silit, s tim jak sili i pozary je jasne. Zato nedostatek pitne vody/jeji kontaminace vede k migraci mnohem rychleji.

    SEJDA: popravde nechapu, co tim chces rict, problem cape town vidim krom sucha i v tomhle (v kalifornii je to podobny se skodama z pozaru, je tam vsude vic infrastruktury nez pred sto lety = vetsi skody a zaroven se tam kumuluje za ty desetileti hmota, ktera skvele hori) .. pridej k tomu sucho a mas perfektni bouri

    PER2: no i Kapske mesto, malem kvuli suchu zkolabovalo. Ale diky vsem bohum, byl kolaps odvracen a dneska uz maji zase 80 - 100 % zasob pitne vody. V nejhorsi moment, meli zasob pod 20 %, kdy uz diskutovali, jestli se ta voda jeste vubec da pit, resp. jestli by se mela pouzivat v nemocnicich.

    JINDRICH:
    California has experienced longer stretches of drought in the earlier history, lasting almost 200 years. This is known has the “megadroughts”. Through the study of tree rings, scientists have found that California had endured multiple droughts that lasted 10 or 20 years during the past 1000 years. The two most severe megadroughts occur in 850 which lasted 240 years and 50 years after that one, another stretched at least 180 years. Droughts in California in the 20th century occurred from 1987 to 1992 and from 1928 to 1934. However, these are considered minor to the megadroughts.

    u nas je na štěstí po delsi dobe celkem vlhko... propadlo se to ale jinde..

    Last year at this time, 2% of the United States was in severe drought.
    Now, it's 31%.
    Snowpack in the California mountains is half of normal.
    This is shaping up to be another disastrous fire season for nearly the entire West

    The new report to the Club of Rome, "The Empty Sea" has been published by Springer. Written by Ugo Bardi and Ilaria Perissi both at the University of Florence, Italy, the book is a review of the situation of Earth's oceans. Can we still increase the production of food from the seas? How about the role of aquaculture? And is there hope of obtaining energy, minerals, and other resources from the sea, as the new concept of "Blue Economy" tells us? Or perhaps it already too late to save the Oceans from a collapse caused by the combined effect of overexploitation, pollution, and global warming? It is a complex story that the book tells starting from the beginning: when our remote ancestors started to explore the sea and its resources.
