    Unsurprisingly, last month observed the "warmest" temperatures on record in the Siberian #Arctic for the month of November

    Some people say that the Arctic is warming twice as fast as the rest of the Earth.

    But that's not true.

    Over the last 30 years, the Arctic has actually warmed more than 4 times as fast as the global average. https://t.co/3eg9u4fBye

    World is in danger of missing Paris climate target, summit is warned | Climate change | The Guardian
    https://www.theguardian.com/...2/world-is-in-danger-of-missing-paris-climate-target-summit-is-warned

    The world is still not on track to fulfil the 2015 Paris climate agreement, the UK’s business secretary Alok Sharma warned, after a summit of more than 70 world leaders on the climate crisis ended with few new commitments on greenhouse gas emissions.

    Sharma said: “[People] will ask ‘Have we done enough to put the world on track to limit warming to 1.5C and protect people and nature from the effects of climate change?’ We must be honest with ourselves – the answer to that is currently no.”

    JIMIQ: vlastne 100%, kdyz si vezmeme ze jeste pred rokem 2030 dosahnou vrcholu. Ale jedna vec jsou projekce a druha to, ze emise uz ted rostou vyrazne pomaleji nez HDP takze je mozne, ze tech 18 Gt CO2 ani nedosahnou.

    Tady pekne popisuji obdobi 2005-2017 v USA tedy HDP (GDP) vs emise CO2, HDP roste 10-50 %, emise CO2 klesaji 5-40 %

    TUHO: pokud vim, tak prohlaseni o 2050 neutralite prislo letos. do te doby cina o snizovani emisi co2 nemluvila a k nicemu se nezavazala. nebo mi neco uniklo?

    JIMIQ: tak budoucnost si nespocitas, ale asi to na pul cesty.
    V roce 2005 meli 2,3 bil. USD a 5,8 mld. t CO2, tj. 2,5 t / 1000 USD.
    Takze kdyz by v roce 2030 meli HDP 21 bil. USD (+/- linearni rust od roku 2005), tak by meli produkovat max. 18.5 mld. t CO2 (35% rustu z roku 2005), pricemz posledni roky produkuji okolo 10 mld. t CO2. Co v clanku nezaznelo je, ze cina opakuje, ze jeste pred rokem 2030 dosahnou vrcholu, tj. hodnota z roku 2030 je az za vrcholem. Nicmene stale plati, ze od roku 2050 chteji byt CO2 neutralni. Tak snad nam nezacnu "nase" CO2 krast ;)

    JIMIQ: je to trochu alibistickej zavazek, kterej urcite s degrowth nepocita. ale v horizontu 10ti let je to u nejlidnatejsi zeme sveta porad lepsi, nez kdyz se loni nehlasili k nicemu

    Nepocital jsem to ale nebude to nakonec tak, ze jelikoz Cinsky HDP v roce 2030 bude trikrat takovy jako 2005, tak ty emise vlastne narostou? :)

    SHEFIK: Nepatří to spíš do Nekvalitní novinářské práce? Je tam dost velký rozpor:
    Čínský prezident podle agentury Reuters slíbil do deseti let snížení emisí CO2 v poměru k HDP o 65 procent.
    vs.
    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

    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 Global Carbon Budget report for 2020 is out.
    Due to the pandemic, they estimate that carbon dioxide emissions will have fallen 6.7% globally in 2020.
    That's the largest absolute decline ever, and the largest percentage drop since World War II.

    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.”
