    Kelp’s Carbon Sink Potential Could Be Blocked by Coastal Darkening - Eos
    https://eos.org/articles/kelps-carbon-sink-potential-could-be-blocked-by-coastal-darkening

    “Coastal darkening, an environmental threat researchers are only beginning to study, is found to dramatically reduce the productivity of kelp.”

    “In New Zealand’s Hauraki Gulf, waves crash against cliffs and pull dirt into the ocean, while boats and storms stir up silt from the seafloor. Rivers carry fertilizer from the mainland that causes light-blocking algal blooms, which mingle with pollution from nearby Auckland. Together, they cloud the coastal ocean, depriving organisms living deeper in the water column of their main source of energy—sunlight.”

    A window of opportunity for methane to slip by nature's filters -- ScienceDaily
    https://www.sciencedaily.com/releases/2022/07/220728143017.htm

    In a new study, just published in Communications Earth and Environment, Stranne and colleagues from Stockholm University and Linnaeus University have combined a new model of the biological behaviour and vertical movements of this microbial filter with existing models of seafloor sediments' physical behaviour. The physical parts of the model include processes such as how cracks form and methane can move up thorough the sediment after methane hydrates melt.

    Christian Stranne explains: "Imagine that the amount of methane rising through the sediment suddenly increases, as might happen if methane hydrate begins to melt faster. It can take decades for the filter to adjust itself to consume methane at the new rate. Our new study shows that during the time that the filter is not reestablished, substantial methane can leak past the filter, and into the ocean water."

    Despite this "window of opportunity," methane from melting hydrates that reaches the seawater faces further methane-destroying processes. These processes make it nearly impossible for substantial methane from methane hydrate melting to reach the atmosphere. However, methods as demonstrated in this study can be applied to other regions where seafloor-released methane is much shallower and is more likely to reach the atmosphere, such as the Arctic continental shelves, according to Christian Stranne.

    "Methane hydrates are a massive storehouse of carbon, so it remains important to understand how they interact with ocean changes, and potentially, the atmosphere, over long and, in the case of our study, rather short timescales. We now know that there is indeed a possible process for melting methane hydrates to temporarily bypass what was previously thought to be a strong filter in the sediment," says Christian Stranne.

    The warming rate is, however, of great importance: "Our results suggest that if our oceans warm at a pace significantly lower than 1 °C per 100 years, the filter can keep up with the pace and remain highly efficient. Unfortunately, we see higher warming rates than that in some of our oceans."

    KEB: "Vzdání se benzínu a nafty by mělo efekt pouze v případě, že by Evropská unie nadále nakupovala ropu a následně ji skladovala v nádržích. To by se týkalo i plynu a černého uhlí.".

    No ano. Ideální by bylo právě koupit ty zásoby v té formě, že by rovnou zůstaly nevytěžené pod zemí. Což se ale dělá blbě, protože to se může tvářit kdekdo, že chce být placený za to, že netěží ropu či uhlí, že jo :-) (protože se blbě dokazuje, že sice má, ale netěží)

    Tyhle moudra opomíjejí jednu věc: to, jak budou vypadat Evropa, budou nakonec otrocky napodobovat rozvojové země. Různé zkresleně, dříve nebo později. Ale napodobovat to budou. A zrovna napodobení elektromobility nakonec poptávku po ropě sníží a poptávku po lokálních zdrojích elektřiny z OZE zvýší. Takže kroky, co děláme v Evropě, je nutné hodnotit nejen z hlediska jejich přímého dopadu - ale i z hlediska toho, že budou nejspíš napodobovány (a to někdy i slepě)

    It’s official, 5% of new cars sold in the US are electric! Why is this number important? Once new technologies take up 5% of the market, the product becomes more mainstream, and demand grows at a faster rate.
    “[T]he US joined Europe and China — collectively the three largest car markets — in moving beyond the 5% tipping point. If the US follows the trend established by 18 countries that came before it, a quarter of new car sales could be electric by the end of 2025. That would be a year or two ahead of most major forecasts.”
    The is great news! With the popularity of EVs on the rise, we can soon leave gas-powered vehicles behind.

    It is a week since the highest temperatures in thousands of years hit the UK.

    It is now an objective reality that this civilisation will collapse at some point in the early 2030s. Long tail possibilities are the late 2020’s and the late 2030’s on the other side.

    Why? Forget global averages 1.5C, 2C – that’s all political distraction. What will bring down the system is physical and biological HARD STOPS and the compounding secondary effects cascading through the system.

    These are objective. Like putting a bullet through someone’s brain. They die. They have nothing to do with social predictions – i.e. complex systems. This is Newtonian cause and effect.

    The key is to look at extreme weather events over the next 20 years. The most important stats are the progressions of the recent past projected into the near future. Record high temperatures are going up by approximately .5C a year e.g. 2019 – 38C 2022 40C in the UK.

    We can do a linear projection therefore that the UK will hit up to 45C heat by 2030 and 50C by 2040 – this is the cool temperate zone scenario.

    Project that onto the warm temperate areas where it is now 45C to 50C (Portugal 47C, Scilly 49C), and we can project up to 55C by 2030 and 60C by 2040. In tropical areas where the present limit is around 55C at present we are looking at 60C by 2030 and 65C by 2040.

    Of course there are good reasons to argue that the yearly average increases will be exponential, not linear, particularly as the #Arctic ice will be melted in the summer around 2030/35 according to peer reviewed papers. These then are conservative projections.

    Moving up the normal distribution curve, let’s say each zone will experience 30 plus days of temperatures around 5C less than the record high temperature each year.

    Okay go and do the maths on the following hard stops – these have come from news stories over the past few weeks:

    - You cannot fly a plane at temperatures over 48C
    - You die within 6 hours at humid temperatures of 50C
    - Major rivers dry up at 40C – (think transport routes)
    - Internet centres cannot function over 35C
    - Roads, runways, railway tracks and wiring melt at 40C
    - Most food crops cannot grow and die at temperatures over 30C

    Add in other predictions from the past few years:

    - Vietnam will be periodically 90% under water within decades (think rice production)
    - Indian wheat production will be 30% down by 2030
    - The US costal property price bubble will burst at some point in the mid to late 2020s
    - 20% of Australian forest on average will burn down by 2040
    - 30% of London houses will be subsiding by mid century
    - Lakes in the US West will be empty by the late 2020’s
    - The Amazon will pass the 20-25% cut down tipping point into collapse within the next 10 years
    - 20% plus, the US western regions will be burning each year by the mid 2030s.

    Some of these predictions are messy and certainty fetish scientists, co-opted by the system, will find holes in them like holocaust deniers find holes in the assessment that 6 million jews died in Nazi Germany (maybe it was 5.5?).

    These lines of argument have nothing to do with clear cool risk analysis and everything to do with another determinism: the psychological literature shows that most people cannot accept what they do not like.

    By the 2030’s this civilisation will be gone, in the sense that regimes in the tropics will have collapsed, and those in warm and cold temperate zones will have become either right wing or left wing state socialist enterprises.

    This state socialism has nothing to do with politics – it is what happens in societies facing existential breakdown.


    Carbon rationing and then rationing of everything else is inevitable. Functional regimes will be putting all their surplus resources into geo engineering. Disfunctional ones will be collapsing into various cults of nihilism and thus disintegration.

    If there is a future, it will now be post-nature. That is a future where the whole geo-physical system is controlled by human technologies – just as happened with agriculture systems over the past half century. We are prisoners of our technologies.


    There is a research job here for some people to collect all the predictions and do projections in a more systematic way – get in touch with me if you can do this.

    The absolute imperative now is #CivilResistance to ensure that the transition to what comes next is democratic and egalitarian rather than fascist and genocidal.

    If we fail, our young people will experience terrible deaths before they reach middle age. Face your responsibilities at this time.

    S poklesem ceny Bitcoinu klesla o 36 % i spotřeba elektřiny pro jeho těžbu | Svět hardware
    https://www.svethardware.cz/s-poklesem-ceny-bitcoinu-klesla-o-36-i-spotreba-elektriny-pro-jeho-tezbu/58038

    Výše uvedená čísla jsou pochopitelně odhady a studie předpokládá, že nynější odběr je někde mezi 5,74 a 17,99 GW, oněch 10,31 GW je pak nejpravděpodobnější odhad.

    Když si to spočítáme, vychází to i po tomto výrazném pádu na roční odběr 90,34 TWh, což překračuje spotřebu celé ČR. Pokud bychom to měli přepočítat na osobní elektromobily, pak by to bylo zhruba 30 milionů vozů (tedy osobní vozový park 5 ČR).
