Va virtuálním klimatickém summitu, který pořádá Británie, vystoupil mimo jiné čínský prezident Si Ťin-pching, který ohlásil závazek snížit do roku 2030 emise oxidu uhličitého v poměru k HDP o 65 procent oproti roku 2005. Zvolený americký prezident Joe Biden na Twitteru potvrdil, že USA se po jeho nástupu do Bílého domu v lednu opět připojí k pařížské dohodě o klimatu.

"Sjednotíme svět, abychom dokázali výrazněji a rychleji pokročit vpřed a rázně řešit klimatickou krizi," napsal příští šéf Bílého domu.

Čínský prezident podle agentury Reuters slíbil do deseti let snížení emisí CO2 v poměru k HDP o 65 procent. Do roku 2030 by podle něj mělo 25 procent spotřebované energie pocházet z obnovitelných zdrojů.

Indický premiér Naréndra Módí řekl, že jeho země do roku 2022 zvýší kapacitu obnovitelných zdrojů na 175 gigawatt, do roku 2030 by to mělo být už 450 gigawatt. Podle něj je Indie na dobré cestě ke splnění závazků vyplývajících z pařížské klimatické dohody, přijaté právě před pěti lety.

Today at the UN #ClimateAmbitionSummit our leaders celebrate their shameless loopholes, their empty words, their distant insufficient targets and their theft and destruction of present and future living conditions - calling it "ambition".
There are no climate leaders.
The only ones who can change this are you and me. All of us, together.

The post-election rise of more right-wing outlets that aim to “out-fox Fox” means the GOP social media machine is poised to accelerate. Fortunately, there is a playbook for closing the gap. But it requires progressives to understand and master how to make content spread virally online and how best to debunk disinformation.
Conservatives have turned the term “Green New Deal” into an emotional weapon—part of their overall narrative casting Democrats as extremist, elitist socialists. The attack isn’t fact-based, but as Dan Kahneman, who won a Nobel prize for his work in behavioral economics, explains, “No one ever made a decision because of a number. They need a story.”
The irony is that there is a compelling, positive story to tell about the Green New Deal. At a time when the pandemic has thrown millions of people out of work and spawned miles-long lines at food banks, a Green New Deal would create millions of well-paying jobs that cannot be outsourced overseas.
These jobs would also address the overriding challenge of our time, the accelerating rise in global temperatures that threatens to make the planet unlivable for today’s young people. A Green New Deal would put Americans to work installing solar panels, building wind turbines, restoring farms and forests to store carbon, and performing a thousand other climate-friendly actions. With government investment priming the pump, a Green New Deal would boost revenues for business as well and thereby pay for itself through the resulting increased tax revenue and sustainable growth.
No surprise, then, that when pollsters describe the Green New Deal’s policies—a fast transition to a 100 percent clean-energy grid and an economy free from carbon pollution—the idea is quite popular with ordinary Americans. Support plummets, however, if pollsters ask people how they feel about “the Green New Deal.”

SHEFIK: Tak tohle není budoucnost, ale současnost. Níže položená lyžařská střediska v Alpách, která se nacházela ve výškách jako když ne u nás, tak dejme tomu na Slovensku, tedy např. 1200-2000m, byla už před 10-20 lety v provozu tak maximálně měsíc-dva v roce a rozvíjela se jen ta výše položená, co jsou cca od 1800 do 3000 m. A situace se zřejmě zlepšovat nebude.

U nás je zvláštností Klínovce a do jisté míry Jizerek a Krkonoš, že jde o první vysoké hory ve směru od moře, takže to množství přirozených sněhových srážek tam nějaký čas bude to oteplení kompenzovat, ale sezóna se tam rozhodně taky zkrátí.

Pořád to ale zatím není srovnatelné třeba se situaci na Tibetské náhorní plošině (ale myšleno mimo Tibet - pohoří Qulian a další) kde některé ledovce ustoupily úpllně, což bude mít katastrofální následky - např. celá pouštní oblast Taklamakan ve vnitrozemí Xingjang se stala pouští tak, že někdy ve středověku (nebo koncem starověku, nebo kdy) právě roztál ledovec, který jí zavlalžoval, takže je to předobraz pro osud dalších regionů, pokud ty ledovce úplně roztajou (v tomhle Evropě nehrozí taková rizika, i když třeba u nás voda ze sněhové pokrývky 2 roky dost citelně chyběla, ale přeci jen, Německo, Polsko a další přímořské regiony čerpají vláhu daleko víc z celoročního přísunu dešťů, než jen z hor, a dokonce Dunaj ani nepramení v Alpách, ale v takové oblasti, kterou když jsem projížděl, tak tam pršelo tolik, že jsem pochopil, proč Dunaj pramení právě tam :-)

The greening of the Earth is approaching its limit

The study, carried out by an international team, concludes that the reduction has reached 50% progressively since 1982 due basically to two key factors: the availability of water and nutrients.

Every major challenge humanity faces, from climate change and unbearable inequality to unpayable debts and involuntary migration, are global problems in need of international solutions. This is our conundrum: Never before have we needed global governance more at a time when many see the United Nations as dysfunctional, including good people working diligently at the United Nations. Clearly, we – and the governments representing us – have a duty to re-imagine new, international institutions capable of addressing these multiple challenges. In this lecture Ioanis Varoufakis outlines the new institutions that humanity must fashion if it stands a chance against socioeconomic and environmental collapse.

A Carbon Price In Canada Of $170 CAD By 2030 Is Great Climate News
https://cleantechnica.com/...2/11/a-carbon-price-in-canada-of-170-cad-by-2030-is-great-climate-news/

The price of $50 CAD per ton was interesting and would have been nudging people to change. The average household that was heating with natural gas would spend a bit more than $200 extra per year, or about $3,300 over the life of a typical residential gas furnace. If they bought a heatpump instead, they’d be spending less than that for electricity for it, and if they replaced the furnace and their air conditioner with the heatpump, they’d be far ahead financially.

Concrete Benefits: Recycling Old Wind Turbine Blades Could Help Cement Industry Cut CO2 Emissions | GE News
https://www.ge.com/...-benefits-recycling-old-wind-turbine-blades-could-help-cement-industry-cut-co2

On average, a single wind turbine operating in the U.S. reduces emissions to the tune of 4,600 metric tons of CO2 each year, according to the Environmental Protection Agency. In 2019 alone, the electricity generated from wind turbines around the world avoided the equivalent of roughly 42 million cars’ worth of CO2 emissions.
...

Now, however, there’s a new way to give old blades a more eco-friendly ending — one that not only recycles the material but puts it to a truly efficient use helping the cement industry dial back its own significant CO2 emissions. “It’s a very elegant solution, because it addresses several requirements for the cement production process, making it more sustainable from multiple perspectives,” says Michelle Simpson, a productivity and technology leader at GE Renewable Energy. “Firstly, it provides energy for the manufacture of cement by replacing coal. It also replaces some of the raw materials that are part of the cement recipe, such as sand and clay, that would otherwise have to be mined or sourced from other locations.”
...
When fed into the crucible of the cement kiln, the material could help cement manufacturers lower CO2 emissions by as much as 27% compared to the traditional manufacturing process, according to Simpson. She says the new initiative will reuse nearly 90% of the blade material by weight. More than 65% of the blade weight will replace the sand, clay and other raw materials that would otherwise be added to the kiln to create the cement. Approximately 28% of the blade weight takes over the role of coal: providing energy for the chemical reaction in the cement kiln.
...
An environmental impact analysis conducted by Quantis U.S., a sustainability consulting group, has found that recycling a single 7-ton blade in this way enables the cement kiln to avoid consuming nearly 5 tons of coal, 2.7 tons of silica, 1.9 tons of limestone, and nearly a ton of additional mineral-based raw materials.
