TUHO: Rozjet vyrobu dusicnanu amonneho prakticky ze vzduchu (viz. zde: [ PETER_PAN @ 3. světová válka aneb kam náš svět směřuje? Status: 2020 ] ) je otazka jednotek mesicu - kdyz to bude problem narodni/potravinove bezpecnosti.

Dusik i kyslik si navic muzeme generovat nejen frakcni destilaci, ale i membranovou separaci (skalovatelne od jednotek litru za minutu az po tisice).

Amoniak se v evrope pokud vim stale vyrabi.

Oxidace amoniaku musi jit rozjet v nejakem "valecnem" rezimu v jednotkach mesicu. Jak mas oxid dusičitý, tak ten s peroxidem vodiku da kyselinu dusicnou. Ta se neutralizuje dalsim molarnim ekvivalentem amoniaku a je pak ochladit a krystalizovat. Pak se do toho prida vapenec/dolomit a je hotovo. Bez reziduji, necistot, tezkych kovu a toho vseho co bylo v hnojivejch v 70. letech za komancu.

Lehce sice ot, ale myslim, ze stejne stoji za precteni ...


Potravinová produkce podle něj může být ohrožena i u nás: „Zhruba 60 procent výnosu u obilovin je dáno minerálním hnojením, zvláště dusíkem. Když toto hnojení přerušíte, máte o 60 procent výnosu méně. Takže jen přerušení dodávky hnojiv se rovná hladomor ze dne na den.“
„A to se může velmi snadno stát. Když dojde k promoření nějakého velkého provozu v továrně, tak vznikne nedostatek hnojiv. Spousta továren je v Číně, takže jsme na ní závislí. Proto by Evropská unie měl přehodnotit politiku přesouvání výrob do Číny,“ nabádá Hejcman.

Stačí, když továrny přestanou dodávat hnojiva, a máme v Česku hladomor ze dne na den, varuje expert | Plus

Arctic ice loss is worrying, but the giant stirring in the South could be even worse
https://theconversation.com/...rrying-but-the-giant-stirring-in-the-south-could-be-even-worse-119822

Almost all (around 93%) of the extra heat human activities have caused to accumulate on Earth since the Industrial Revolution lies within the ocean. And a large majority of this has been taken into the depths of the Southern Ocean. It is thought that this effect could delay the start of significant warming over much of Antarctica for a century or more.

However, the Antarctic ice sheet has a weak underbelly. In some places the ice sheet sits on ground that is below sea level. This puts the ice sheet in direct contact with warm ocean waters that are very effective at melting ice and destabilising the ice sheet.

Scientists have long been worried about the potential weakness of ice in West Antarctica because of its deep interface with the ocean. This concern was flagged in the first report of the Intergovernmental Panel on Climate Change (IPCC) way back in 1990, although it was also thought that substantial ice loss from Antarctica wouldn’t be seen this century. Since 1992 satellites have been monitoring the status of the Antarctic ice sheet and we now know that not only is ice loss already underway, it is also vanishing at an accelerating rate.

The latest estimates indicate that 25% of the West Antarctic ice sheet is now unstable, and that Antarctic ice loss has increased five-fold over the past 25 years. These are remarkable numbers, bearing in mind that more than 4 metres of global sea-level rise are locked up in the West Antarctic alone.

TADEAS:

Climate scientists: the Arctic is currently experiencing an abrupt climate change event and summer sea ice looks set to vanish by 2035. Most of us fully expect global warming of 2.5 - 4.5°C.

Media: we could still avoid warming of 1.5°C by 2100. Arctic sea ice? Never heard of it.

Dead Zones: Industrial Agriculture versus Ocean Life
https://climateandcapitalism.com/2020/08/12/dead-zones-industrial-agriculture-versus-ocean-life/

The dead zone in the Baltic Sea is larger and in many ways more destructive than the one in the Gulf of Mexico. In 2007, the nine nations that surround the sea adopted an Action Plan “to achieve a Baltic Sea in good environmental status by 2021,” including elimination of eutrophication. They agreed: “By 2010 to halt the degradation of threatened and/or declining marine biotopes/habitats in the Baltic Sea, and by 2021 to ensure that threatened and/or declining marine biotopes/habitats in the Baltic Sea have largely recovered.”[18]

In 2018, with only three years left to achieve those ambitious goals, a scorecard published by WWF found that “all nine Baltic Sea countries have failed to make good progress,” and that “eutrophication status of most parts of the Baltic Sea remains poor and even deteriorating in some sub-basins.” The overall results were “bleak and unsatisfactory.”[19]

In WWF’s view, “the Baltic Sea environment remains in a critical state due to lack of efficient delivery of measures and management.” But what their study actually reveals is unwillingness to challenge an agricultural system that, as sociologist Philip McMichael puts it, “is ultimately about combining commodified inputs (seeds, fertilizer, antibiotics, privately-owned genetic materials, pesticides and so on) with land or water or factory farms to produce outputs as ingredients of processed commodities to fuel labor or machinery, without regard for social or ecological consequence.”[20]

Unless fundamental changes are made to the agro-industrial system that rules today, coastal dead zones will continue to grow and multiply

The IPCC scenarios are clear that, without speculative negative emissions schemes on a mass scale, the only way to keep global warming under 1.5C or 2C is for high-income nations to adopt degrowth strategies.

It's remarkable that this fact gets so little attention.

2019 Is Green Growth Possible?
https://www.tandfonline.com/doi/abs/10.1080/13563467.2019.1598964

The notion of green growth has emerged as a dominant policy response to climate change and ecological breakdown. Green growth theory asserts that continued economic expansion is compatible with our planet’s ecology, as technological change and substitution will allow us to absolutely decouple GDP growth from resource use and carbon emissions. This claim is now assumed in national and international policy, including in the Sustainable Development Goals. But empirical evidence on resource use and carbon emissions does not support green growth theory. Examining relevant studies on historical trends and model-based projections, we find that: (1) there is no empirical evidence that absolute decoupling from resource use can be achieved on a global scale against a background of continued economic growth, and (2) absolute decoupling from carbon emissions is highly unlikely to be achieved at a rate rapid enough to prevent global warming over 1.5°C or 2°C, even under optimistic policy conditions. We conclude that green growth is likely to be a misguided objective, and that policymakers need to look toward alternative strategies.
