    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."

    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?

    Europe's Leaked Hydrogen Strategy Is Very Ambitious | OilPrice.com
    https://oilprice.com/...y/Energy-General/Europes-Leaked-Hydrogen-Strategy-Is-Very-Ambitious.amp.html

    in a recent Tracking Energy Integration 2020 report, the IEA calls hydrogen one of several integration technologies that are ‘increasingly crucial’ for a low-carbon energy transition. The report notes that important political momentum had been building through last year, listing ten international initiatives and national plans that appeared during 2019. These include top level G20 discussions and target-setting plans by Korea, Japan, Netherlands, Australia and Canada.

    Clearly the hydrogen movement is at a critical moment when continuing innovation is required. The role of government will remain important as fledgling industries seek to gain scale and find markets. Governments will need to provide direct, targeted support for projects that can achieve technical and market advances. And they will need to help stimulate demand in sectors where good near-term opportunities appear.

    ...

    The shifting emphasis can be seen especially in Northern Europe, where large concentrations of projects are now found. Renewable energy will power electrolysers to produce hydrogen for industries in northern industrial centers. Other projects focus on power and heat for urban districts. Key applications include large-scale electrolysis, carbon capture, utilization and storage (CCUS), and utilization of natural gas networks.

    ...

    In Germany, a power-to-gas project in Emsland in the Ruhr region has been called ‘Hybridge’ for its capacity to couple electric and gas networks. In a partnership of transmission system operator Amprion and gas net operator Open Grid Europe (OGE), electricity from renewable energy will be converted, by means of electrolysis, into hydrogen and methane. The companies will deploy a 100 MW electrolyser, with the resulting hydrogen transported by an OGE hydrogen pipeline and the existing gas pipeline network throughout the Ruhr and beyond. The project is anticipated to start operation in 2023.

    In France, in the Les Hauts de France region around Dunkirk, one of the world’s most ambitious power-to-gas projects will build five 100 MW hydrogen electrolyser production units over five years. The project, a partnership of France’s H2V Industry and Norway’s HydrogenPro, will introduce hydrogen into the natural gas distribution network in order to decarbonize the natural gas used for heating and cooking as well as for transport.

    These ambitious European projects have large-scale electrolysis counterparts in North America. Most notable is a project of the British Columbia-based Renewable Hydrogen Canada (RH2C), which is backed by a private sector utility and investors. The company is planning to build a large electrolysis plant in BC, to produce renewable hydrogen through water electrolysis powered by local hydropower and winds off the Rockies.

    ...

    An enormous pilot project to convert the gas networks to hydrogen in the north of England is being planned now. First announced in 2016, the H21 North of England (H21 NoE) project, is a collaboration of two British gas distributors, Northern Gas Networks and Cadent, and Norway’s Equinor (formerly Statoil). They have produced a hydrogen blueprint that will utilize the existing natural gas distribution infrastructure serving a region of 5 million inhabitants including several large cities for domestic and industrial users, with applications including heat, power and transport.

    The project’s planners view it as a way to achieve the ‘deep decarbonization’ that could not be reached with renewable electric power alone. To do so will require carbon capture and storage (CCS). Equinor’s role is to build a hydrogen production facility utilizing a standard reforming process with natural gas. The captured CO2 will be transported offshore to undersea storage. A specially built hydrogen transmission pipeline will link to the local gas distribution networks. The new transmission pipeline is required because injecting hydrogen into gas transmission pipelines is more difficult (although Italy’s Snam has already demonstrated the feasibility of blending hydrogen up to 10% in gas transmission grids).

    Project implementation is to occur between 2028 and 2034. It is anticipated to achieve deep decarbonization of 14% of the UK's heat demand by 2034. Its large scale and significant impact on carbon emissions will make H21 NoE the world’s first at-scale hydrogen economy. Should it succeed, it will lay a basis for expanding such a system across the entire UK, decarbonizing a large percentage of domestic heat, transport and power by 2050

    In a new post, @Ken_Medlock, senior director of @CES_Baker_Inst, and his coauthors explore new processes for steel and iron production that could reduce #emissions and potentially provide both environmental and economic benefits.

    Steel, Hydrogen and Renewables: Strange Bedfellows? Maybe Not… – Baker Institute Blog
    http://blog.bakerinstitute.org/.../05/15/steel-hydrogen-and-renewables-strange-bedfellows-maybe-not/

    Hydrogen-based DRI has received increasing attention as an enabler for renewable energy use and CO2 emission mitigation with pilot projects in Germany and Sweden, among others. A DRI enabled EAF route that uses hydrogen from renewable power reduces CO2 emissions by 80-95%, compared to the blast furnace. However, significant investment is required to realize such scalable reductions in CO2 emissions across the steel industry. Based on forecasts for steel production and considering an increase of 15-29% in the DRI route for primary iron production, 350 Mt of new DRI capacity would be needed by 2050, a six-fold increase from today. This translates to roughly 200 GW of electrolyser capacity to produce 5 EJ of green hydrogen, if all DRI routes were to use hydrogen. In a country context, Germany would need 100 terawatt-hours (TWh) of renewable power (20% of today’s national electricity consumption) to fully decarbonise the steel sector alone with DRI from green hydrogen.

    Under certain conditions, renewable hydrogen-based iron production can become the least-cost supply option at a CO2 price of around US$67 per tonne, assuming the availability of low-cost renewable electricity. Of course, future projects will drive learning and innovation and tend to reduce this, which highlights the role that continued research and development can play. Indeed, hydrogen-based iron making is technically feasible, and various producers are working to develop this option further. A core step is direct reduction based on pure hydrogen rather than on natural gas. Projects in the pipeline include a facility to be deployed by Thyssenkrupp (electrolysis) and MIDREX (DRI plant) with Arcelor-Mittal in Hamburg to produce 100,000 tonnes per year of DRI using green hydrogen from electrolysis. The plant will initially operate on natural gas; hydrogen will be considered once low-cost offshore wind has ramped up. Four pilot-plants in Europe will come in operation over the coming years to produce green hydrogen-based steel. In the US, flash ironmaking is being explored

    URZA:

    Ha! Tak mi právě zavolal člověk z CHMU.. asi se mu nechtělo psát mail, psal jsem mu nějaký dotazy k tomu. Oni mají daleko víc dat k dispozici. tak mě zajímal jeho názor. Říkal že:

    1. Byť je tato epizoda úbytku podzemních vod už neobvykle delší (5 let, v 2018 prej v hodně místech naměřili absolutní minimum), tak to ještě nemusí znamenat nutně trend, může se to otočit. Mluvil i o jiných víceletých suchých obdobích, např. prej ve 40 letech po válce byo nějaké větší sucho. Štěžoval si, že data za 80 let, který máme je prý málo :)

    2. Důvod proč ta podzemní voda teď ubývá je že je málo sněhu a na jaře málo prší. Prší sice v souhrnu za rok podobně jako dřív, ale prší víc v létě a hodně naráz, takže voda se rychleji odpaří, víc ji zadrží vegetace (která na jaře ještě není) a nedostane se do hloubky.

    Encountering an Essential Lesson in the Church Forests of Ethiopia – Gaianism
    http://gaianism.org/essential-lesson-church-forests-ethiopia/

    Somehow, the Ethiopian Church evolved to see forests as sacred and, through the design of their institutions and teachings, embedded this directly into their system code. Church services, weddings, baptisms, community meetings—the church is at the center of all of these, and thus so is the forest. Even one’s final moment differentiated from the Gaian whole takes place here: all Ethiopian Orthodox worshippers are entitled to be buried in the church forest.

    As the articles describe, people cross themselves as they enter into the forest, as they cross the inner courtyard wall, as they enter the church and the communion circle, recognizing that with every step toward the center they enter a more holy reality. The forests, where humidity and air temperature change markedly, add to this numinous experience, so it’s not hard to imagine why now, when church forests are literal oases in the midst of a desertified agricultural system, these feel sacred. They are now both Edenic gardens and Noah’s arks.

    But 1600 years ago, when far more of Ethiopia was forested, and the forests’ permanence surely seemed unquestioned, why did this unique Christian mutation take root? That is a question I don’t have an answer for, but the more important point is that whatever the reason, it is this religious system that has essentially prevented the entire country from becoming a desert. The church forests are like the country’s appendix, holding a small reserve of healthy organisms, until the infection—in this case modern civilization—ceases and life can once again recolonize the intestines, or in this case, the land. (And if you didn’t know that about the appendix’s role in the human body, now you do!)

    This is why cultivating not just personal ecocentric spiritualities or philosophies but actual living religious systems is essential. There is far less power or longevity in a personal spirituality that is not shared, that doesn’t have a community around it, that doesn’t cultivate shared rituals, that doesn’t build institutions.

    So what does that mean for us? It means: Gaians need to build a Gaian Mission. A Gaian Church. A Gaian Guild. A religious system that will grow and endure and help get humanity through the dark age that’s most likely just over the horizon. That will preserve and spread again biodiversity and essential human knowledge like permaculture, midwifery, and basic medicine so that Gaians one day can help bring about a new flourishing of culture—but this time in a way that sustains the Earth rather than comes at the cost of the Earth. But that requires a religious system, one that nurtures congregants and nudges them: to be their best and most eco-sacred selves; to share this system with others; and above all to continually recognize our dependence on and our being part of Gaia. If we do that, perhaps one day, a millennium from now, people will write about how Gaians’ sacred preserves and stores of wisdom helped to both rewild and recivilize the world.

    Deforestation in Africa accelerates ~ UN food agency | CGTN Africa
    https://africa.cgtn.com/2020/05/07/deforestation-in-africa-accelerates-un-food-agency/

    Africa is the only continent in the world where deforestation is accelerating, according to key findings of a five-year report released Thursday by the United Nations Food and Agriculture Organization (FAO).

    “One explanation is certainly population growth in the region. Much of the deforestation in the region is due to small-scale subsistence agriculture,” Branthomme told AFP.

    Insufficient poverty reduction, combined with population growth, “is increasing the pressure on forests, which is very unfortunate since forests in Africa are also a very important source of food, firewood, wood energy,” she added.

    At the global level, forest loss has continued to slow, though this positive trend has weakened over the past decade.

    Amid Oil Price Crash, Climate Change Protesters Urge Divestment From Fossil Fuels
    https://foreignpolicy.com/...crash-revives-fossil-fuel-divestment-campaigns-climate-change-activism/

    “There might not be another moment where there is the political and economic window to take the drastic action on climate that is necessary,” said Connor Chung, the communications coordinator for Divest Harvard, a student activist organization. “We don’t have the luxury of trusting that we can nudge the industry into behavior or that the market will fix the problem by itself.”

    Divestment organizers—climate activists who are pushing government and financial institutions to divest from the fossil fuel industry—have been using the pandemic’s ripple effects throughout the global economy, most notably through the oil and gas sector, to demonstrate just how dire the need to remove pension funds and other investments from the struggling sector really is.

    biden / climate

    https://threadreaderapp.com/thread/1262110174698811392.html

    We're seeing climate policy teams emerge to try and fill the deficit in Biden's plans & the void left by the suspension of the Bernie campaign,& it's important to understand that they aren't offering unique policies: this may be a strategic shift, and one that is questionable. /1

    Let's start with the basics: writing policy isn't hard. Most of the ideas were born from the frontlines & organizers, with feedback into academic/policy spaces- primarily to legitimize them. What's hard is navigating political landscapes, which have shifted. /2

    The big prize is defining Biden's climate plan right now, which is garbage. Biden needs the youth vote to win,& youth care about climate. That gives us tremendous leverage.

    These climate think tanks are positioning themselves as a solution for Biden & climate activists /3

    The big question is 'whose side are they on?' It can't be both, even if they believe it.

    So it's important to understand their self-interest- whether it's career-building, saving the planet for kids, etc. & it's VERY important to understand their theory of change. /4

    If their theory of change relies on closed-door deal-making, climate activists will lose. This has been the strategy for decades, & it's cost us dearly.

    If it's grounded in leveraging the power of a mass movement to win demands that they turn into policy, that's better /5

    My concern is that there is more focus on getting positioned within the Biden camp than enabling the movement, & the fear of another Trump presidency is being used to excuse a strategic shift to focusing on a primarily inside vs. outside strategy./6

    Here's the thing: Biden will lose without the youth vote, which is more diverse & concerned w/ justice & climate than other generations. He will need to make large concessions to build enthusiasm for his campaign. I don't think attempts to manufacture consent will be enough. /7

    The movement is in shock right now, but PEOPLE still have the power. If climate policy groups are conceiving their value as connecting Biden w/ voters, then they need to authentically represent the will of people. Not through grasstops 'consultation,' but by aligning w/ them /8

    People need to be making grassroots demands. The demands need to be winnable, have science-driven timelines, materially improve people's lives,& alter the relations of power.& we must fight for them.

    This criteria is important for policymakers too-esp altering power relations /9
    The Biden climate taskforce may host some of these dynamics. It may be good that Bernie appointed people that have a theory of change anchored by people power.

    Policy groups will compete for influence.
    But the participation of people will determine its value. /10

    A return to closed-door deal-making would be the nail in the coffin of real change. The power to win real change ultimately lies with PEOPLE, & policy groups w/ interest in real change need to join movements & adhere to the will of people-not replicate hierarchies of power. /11

    We can't allow fear to drive us back toward familiar patterns of "change-making" that have failed to deliver the progress we need. There is too much at stake to stop fighting- we have leverage right now. The New Deal wasn't gifted: it was a concession to prevent revolution /12

    We are powerful, and we must be brave enough to use our power for authentic victories. If we stick together, we can win. A better world is still possible. 13/13

    HydroWing, Tocardo partner on production of hydrogen from tidal power - Green Car Congress
    https://www.greencarcongress.com/2020/05/20200518-hydrowing.html

    Roughly 70 million tonnes of hydrogen are already produced annually representing a market worth more than US$121 billion. Hydrogen is utilized for a wide range of current industrial processes from ammonia, methanol and metals production and refinery of oil. Currently 98% of this demand is met by non-green sources resulting in around 830 million tonnes of CO2 a year—equivalent to the emissions of the UK and Indonesia combined.
