    BREAKING: It is now officially Australian law that the Environment Minister has a duty to avoid causing personal injury and death to Australian children from carbon emissions when approving a coal extension project.

    MASTODONT: Obavam se, ze s vanickou se vyleje i dite. Dovoz dreva pres ocean a jeho paleni v elektrarnach v UK nebo NL je samozrejme zvrhlost. Na druhou stranu soused ma kotel na peletky, ktere si vozi z cca 7km vzdalene pily, kde je vyrabi z odpadu z vyroby. IMHO je toto lepsi, nez palit plyn, ktery kudy tece, tudy unika a nakonec stejne vygeneruje CO2. O samovyrobe dreva na venkove ani nemluve, tam ta uhlikova stopa je oproti tomu "prumyslovemu" spalovani dreva zanedbatelna (tedy za predpokladu, ze se hospodari staraji o sve lesy rozume, coz plati jen u nekterych, ale zacina je k tomu tlacit i kurovec, takze bych to nevidel nejak cerne).

    Ono je to vzdycky slozitejsi - kdyz maji lidi levne drevo k dispozici, tak zase (nekteri) zbytecne pretapi domy (znam takove, kteri se chlubi svymi 27C v obyvacich, protoze drevo maji "zdarma" - a to v nezateplenych domech). Na druhou stranu tolik vychvalovana tep. cerpadla jsou sice nasobne efektivnejsi, ale zalezi, jaka elektrina do nich tece. (Super kombinace mi v tomto ohledu prijde FVE + TC + akumulacni nadrz.) Kdyz vidim ta cerpadla kolem novych domu a zaroven vidavam plne vagony kurovcoveho dreva na vyvoz buhvikam (Polsko, Cina, atp), tak mi to neprijde jako rozumny. My Cinanum drevo, oni nam elektrokomponenty vyrobene z uhelne (prevazne) energie. Je to cele proste blbe...

    A new study found that carbonate rock mounds on the ocean floor host communities of microbes that actively consume methane, a greenhouse gas that is particularly potent if released into the atmosphere.
    The researchers found that rock-inhabiting microbes consumed methane 50 times faster than microbes that live in sediment.
    These microbes therefore play a crucial role in regulating the Earth’s temperature by consuming methane before it travels up into the water column and into the atmosphere.

    Studies add to concern about climate tipping
    https://phys.org/news/2021-07-climate.amp

    In the first study, the authors show in a coupled ocean-atmosphere model how the mid-latitude wind systems over Europe and North America has a probability to tip between different types of behavior (or different regimes, as climate scientists say) depending on the strength of an El Niño. In other words, the climate phenomenon El Niño—during which heat builds up in the surface layers of the eastern tropical Pacific Ocean—determines whether the mid-latitude wind system in the U.S.A. will be more or less likely to shift abruptly between one regime and another.

    Such probabilistic climate tipping complicates prediction, which is generally based on the assumption that climate systems change gradually in a more predictable manner. The findings, - co-authored with Stéphane Vannitsem and Jonathan Demaeyer from the Royal Meteorological Institute of Belgium and published in Journal of Advances in Modeling Earth Systems, thus explain why the patterns of precipitation and temperature during and after an El Niño have been difficult to predict with accuracy up till now.

    ...

    The other result concerns rate-induced tipping. This kind of climate tipping takes place not because a certain threshold level is reached, like a CO2 level in the atmosphere, but rather because the rate of change is too fast for the system to evolve gradually.

    The study—co-authored with Stefano Pierini from the Parthenope University of Naples and published in Scientific Reports, finds rate-induced tipping in a simplified model of the wind-driven ocean circulation for the first time. In this model study, the Gulf Stream—which distributes heat to the North Atlantic and plays an important role in keeping the temperatures in Western Europe relatively mild—tips between regimes when CO2 is introduced at a rapid rate into the model

    Such a result is highly relevant as levels of CO2 in the atmosphere currently go up at an unprecedented rate. If the Gulf Stream eventually tips in this rate-induced manner, Western Europe could experience rather abrupt changes to its climate.

    "These results indicate that climate tipping is an imminent risk in the Earth System. Even the safe operating space of 1.5 or 2.0 degrees above present generally assumed by the IPCC might not be all that safe. According to the precautionary principle, we must consider abrupt and irreversible changes to the climate system as a real risk

    The climate crisis will create two classes: those who can flee, and those who cannot | Peter Gleick | The Guardian
    https://www.theguardian.com/commentisfree/2021/jul/07/global-heating-climate-crisis-heat-two-classes

    the climate crisis is going to produce two classes of refugees: those with the freedom and financial resources to try, for a while at least, to flee from growing threats in advance, and those who will be left behind to suffer the consequences in the form of illness, death and destruction.

    ...

    humans that can move will move. Just as millions migrated over the past half-century from the colder north to sunny, warm communities in Florida, Arizona, New Mexico and southern California, we will certainly see a massive reverse migration in the coming half century away from the coasts, extreme heat and water shortages to places thought to be more favorable. We’re already seeing refugees on the southern border of the US fleeing countries suffering from drought and disasters. If greenhouse gas emissions continue unabated, some models suggest that more than a million climate refugees may move from Central America and Mexico to the United States. In April, the UN high commissioner for refugees released a report showing that climate- and weather-related disasters already displace more than 20 million people a year, and a report from the Australian Institute for Economics and Peace suggests that more than a billion people could be displaced by climate and weather disasters by 2050.

    TADEAS: Nová kritéria, nový směr myšlení, nové vlaječky na demoškách!! Ale pozor, nejen u biopaliv se tvrdili hovadiny ...

    Ačkoliv spalování biomasy, tedy například dřevěných pelet bylo v posledních letech považováno za ekologický způsob výroby energie nejen v rodinných domech – vědci mají nyní na toto využívání dřeva jiný názor. Některé důkazy totiž nasvědčují, že využívání dřeva a dřevěných pelet může být pro globální klima horší než spalování uhlí a plynu. Evropská unie tak už chystá změnu pravidel.

    Spalování dřeva je podle vědců horší než uhlí a plyn, Evropská unie ho chce omezit | EnergoZrouti.cz

    A tak dále a dále, na vědu a pořádné dokazování není čas, hlavní jsou demošky a rychlá gesta.

    MASTODONT: v roce 2011 tomu nebylo jinak, jen citujes z toho clanku jednu vetu. taky je tam: "Je pravdou, že v minulosti existovaly případy, kdy i kvůli biopalivům byly vykáceny deštné pralesy a je pravdou, že v takovém případě nemůže být o nějaké úspoře skleníkových plynů ani řeč. K zamezení těchto extrémních jevů mají však sloužit nově zavedená kriteria udržitelnosti výroby biopaliv"

    Biopaliva produkují až třikrát více emisí CO2 než diesel vyrobený jen z ropy??? Zajímavé, v roce 2011 to přece bylo jinak:

    JAKÁ JE SKUTEČNOST: Biopaliva vedou k úspoře skleníkových plynů - některá méně, některá více, ale k úspoře CO2 dochází vždy.

    World ‘must step up preparations for extreme heat’ | Climate change | The Guardian
    https://www.theguardian.com/science/2021/jul/07/world-must-step-up-preparations-for-extreme-heat

    Geert Jan van Oldenborgh of the Royal Netherlands Meteorological Institute, said that up until last year standard climate models had assumed that there was an upper boundary to heatwaves that moved roughly twice as fast as broader global heating trends.

    “We thought we knew what was going on … Then this heatwave came which was way above the upper bound. With the knowledge of last year this was impossible. This was surprising and shaking,” he said. “We are now much less certain about heatwaves than we were two weeks ago. We are very worried about the possibility of this happening everywhere but we just don’t know yet.”
