1177 B.C.: When Civilization Collapsed | Eric Cline
https://youtu.be/M4LRHJlijVU


Consider this, optimists. All the societies in the world can collapse simultaneously. It has happened before.

In the 12th century BCE the great Bronze Age civilizations of the Mediterranean—all of them—suddenly fell apart. Their empires evaporated, their cities emptied out, their technologies disappeared, and famine ruled. Mycenae, Minos, Assyria, Hittites, Canaan, Cyprus—all gone. Even Egypt fell into a steep decline. The Bronze Age was over.

The event should live in history as one of the great cautionary tales, but it hasn’t because its causes were considered a mystery. How can we know what to be cautious of? Eric Cline has taken on on the mystery. An archaeologist-historian at George Washington University, he is the author of "1177 B.C.: The Year Civilization Collapsed." The failure, he suggests, was systemic. The highly complex, richly interconnected system of the world tipped all at once into chaos.

"1177 B.C.: When Civilization Collapsed" was given on January 11, 02016 as part of Long Now's Seminar series. The series was started in 02003 to build a compelling body of ideas about long-term thinking from some of the world's leading thinkers. The Seminars take place in San Francisco and are curated and hosted by Stewart Brand. To follow the talks, you can:

Sdílím povídání o zobrazování (vědeckém a uměleckém) klima změny a tajících ledovců s polární ekoložkou Marií Šabackou a filozofem Lukášem Likavčanem. Dotkli jsme se i právních rámců, mezinárodní kooperace a Arktické rady:

TADEAS: vsichni cesti politici jsou podelani ze zamestnancu automobilek a navazujiciho retezce, ktery tu behem 30 let korupcnima danovyma pobidkama vypestovali. Takze ted je tu strasliva hromada lidi zavisla na moralne zastaralem techno-ekonomickem modelu a nikdo nema odvahu jim rict, ze se piska konec.

Governments falling woefully short of Paris climate pledges, study finds | Climate change | The Guardian
https://www.theguardian.com/science/2021/sep/15/governments-falling-short-paris-climate-pledges-study

Every one of the world’s leading economies, including all the countries that make up the G20, is failing to meet commitments made in the landmark Paris agreement in order to stave off climate catastrophe, a damning new analysis has found.

Less than two months before crucial United Nations climate talks take place in Scotland, none of the largest greenhouse gas emitting countries have made sufficient plans to lower pollution to meet what they agreed to in the 2015 Paris climate accord.

osel je známý tím, že ohledně globálního oteplování rád rozšíří cokoliv, z čeho vyjde jakýkokliv jiný výsledek neže nutnost masivní podpory jaderné energie tady a teď :-) ovšem s tím dřevem je to fakt zajímavé, jestli je pravda, že dřevěné uhlí ve spálených lesích není vlastně úložiště uhlíku, ale dál katalyzuje rozklad biomasy, tak je to vlastně docela vážný problém....

(každopádně uložení dřeva na budoucí použití coby stavebního materiálu mi pořád přijde jako nejperspektivnější carbon capture vůbec, i po přečetení tohohle článku.. lesy je dobré občas pokácet, jen se to nesmí ani nechat shnít, ani spálit..)

PER2: to nejsou dobry zpravy. beznej obcan tuhle komplexitu vztahu dat nemuze. A uniky urcite budou, dosavadniho metanu z ropnejch lozisek, stejne tak vodiku, jak se bude budovat novej energetickej ekosystem...

When scientists analyzed air samples trapped in drilled cores of Antarctica's ice, they found atmospheric hydrogen had increased 70 percent over the course of the 20th century.

Even as recent air pollution laws have sought to curb fossil fuel emissions, hydrogen emissions have continued to surge with no signs of slowing down. And there's a chance that leakage is to blame.

No one has directly measured how much hydrogen leaks from these processes, but initial estimates suggest it could be significant.

They can't be sure this is where the hydrogen is coming from – hydrogen emissions from coal combustion are also seriously understudied – but the authors argue it's worth investigating more.

Especially since green hydrogen processes, which split hydrogen from water to create carbon-free power, could also result in substantial leakage if they are one day scaled up, as some climate scientists and environmentalists hope they will be.

If hydrogen one day leaks from industrialized hydrogen gas plants, experts are troubled it could increase the lifetime of methane in our atmosphere, a greenhouse gas 20 times more potent than carbon dioxide.

hodne asi urobi ten priemysel, ak sa napr. v nejakej automobilke, kde pracuje 100 ludi spotrebuju hektolitre vody denne, tak tam bude ten priemer na osobu asi vysoky

spotreba vody mierne klesla, asi ludom doslo, ze to nie je tak samozrejma vec, my mame podla udajov z vodaren dlhodobu priemernu dennu spotrebu 0,27m3 na domacnost (4 osoby) co je teda pod priemerom CR, tak to mam radost, ze moc neplytvame

Almost 90% of the $540bn in global subsidies given to farmers every year are “harmful”, a startling UN report has found.

This agricultural support damages people’s health, fuels the climate crisis, destroys nature and drives inequality by excluding smallholder farmers, many of whom are women, according to the UN agencies.

The biggest sources of greenhouse gas emissions, such as beef and milk, received the biggest subsidies, the report said. These are often produced by large industrialised groups that are best placed to gain access to subsidies.

Without reform, the level of subsidies was on track to soar to $1.8tn (£1.3tn) a year by 2030, further harming human wellbeing and worsening the planetary crisis, the UN said.
