    TUHOKlimaticka zmena / Destroying the Future Is the Most Cost-Effective


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    China's CO2 emissions have started falling – is this finally the peak? | New Scientist
    https://www.newscientist.com/article/2480289-chinas-co2-emissions-have-started-falling-is-this-finally-the-peak/

    China, the world’s largest emitter of carbon dioxide, has seen a slight decline in those emissions over the past twelve months, even as demand for power has gone up. This is an encouraging sign the country’s massive buildout of clean energy has begun to displace fossil fuels – but emissions could still surge again.

    That is according to an analysis of China’s economic and energy data by Lauri Myllivirta at the Centre for Research on Energy and Clean Air, a research organisation in Finland. According to the report, published in Carbon Brief, China’s CO2 emissions have declined by 1 per cent over the past 12 months; in the first quarter of 2025 alone emissions declined by 1.6 per cent relative to last year.
    ...
    This isn’t the first time China’s CO2 emissions have dipped. For instance, they dropped in 2022 as the economy came to a standstill during covid-19 lockdowns. But this is the first time emissions have fallen even as the country has used more power. “That, of course, means the current fall in emissions has a much better chance of being sustained,” says Myllivirta.

    This is mainly a consequence of China’s record build-out of solar, wind and nuclear power, which is beginning to eat into the total electricity generated by burning fossil fuels. Wider economic shifts away from cement and steel production, which are carbon-intensive industries, have also contributed to the decline. Another factor is the jump in the share of people driving electric vehicles, which has cut into the demand for oil.

    If China maintains these trends, its carbon emissions could continue to fall. A sustained drop would indicate the country has passed peak emissions, putting it several years ahead of its 2030 target. The achievement would represent a substantial physical and psychological milestone for efforts to tackle climate change, says Myllivirta.

    Denmark rethinking 40-year nuclear power ban amid Europe-wide shift | Denmark | The Guardian
    https://www.theguardian.com/world/2025/may/14/denmark-rethinking-40-year-nuclear-power-ban-amid-europe-wide-shift

    Denmark is reconsidering its 40-year ban on nuclear power in a major policy shift for the renewables-heavy country.

    The Danish government will analyse the potential benefits of a new generation of nuclear power technologies after banning traditional nuclear reactors in 1985, its energy minister said.

    Large Cloud Feedback Confirms High Climate Sensitivity
    https://mailchi.mp/caa/large-cloud-feedback-confirms-high-climate-sensitivity

    Earth is getting darker, reflecting back to space a decreasing portion of the sunlight incident on Earth. This provides crucial information on cloud changes and climate sensitivity. See - 14 May Large Cloud Feedback Confirms High Climate Sensitivity -

    “Earth’s albedo (reflectivity) declined over the 25 years of precise satellite data, with the decline so large that this change must be mainly reduced reflection of sunlight by clouds. Part of the cloud change is caused by reduction of human-made atmospheric aerosols, which act as condensation nuclei for cloud formation, but most of the cloud change is cloud feedback that occurs with global warming. The observed albedo change proves that clouds provide a large, amplifying, climate feedback. This large cloud feedback confirms high climate sensitivity, consistent with paleoclimate data and with the rate of global warming in the past century.”

    Just Stop Oil has ended its campaign of direct action, yet many activists still face years in prison. In the final episode, Rivkah and Clare find out whether their commitment to their cause has wavered. They also speak to veteran climate campaigner Roger Hallam, currently serving a four-year sentence, about his role in sending young activists to prison.

    Btw Tykac se netaji tim, ze se snazi pripravit "konzervativni (cti fosilni) revoluci" ... Tak zatim mu to slape

    O tom, že se miliardář a uhlobaron Pavel Tykač prostřednictvím radního ČT Pavla Matochy snaží mít vliv na Českou televizi, sice mluví [například někteří politici](https://medium.seznam.cz/clanek/marek-hilser-radni-ceske-televize-porusuji-zakon-meli-by-deklarovat-stret-zajmu-88056), nikdo však dosud nepředložil konkrétní důkazy. Deník N nyní zjistil, že se Tykač v roce 2022 osobně účastnil klíčové schůzky s tehdejším generálním ředitelem ČT Dvořákem a Pavlem Matochou, který v té době předsedal Radě ČT.

    Tory shadow energy minister claims 2050 net zero goal ‘not based on science’ | Conservatives | The Guardian
    https://www.theguardian.com/politics/2025/may/13/tory-shadow-energy-minister-claims-2050-net-zero-goal-not-based-on-science


    The Conservative party’s energy spokesperson has attacked leading climate scientists as biased and claimed Kemi Badenoch could take the UK out of the Paris climate agreement.

    Andrew Bowie, the acting shadow secretary for energy, told the Guardian that the target of reaching net zero greenhouse gas emissions by 2050 – passed into law by Theresa May – was “arbitrary” and “not based on science”.

    He also indicated that the UK’s participation in the 2015 Paris climate agreement was up for reconsideration in the party’s ongoing review of key policies. The only other country to have withdrawn from the agreement is the US, twice, under Donald Trump.

    Bowie said: “We are not climate deniers and while we believe in getting to net zero, what we shouldn’t do is be hamstrung by arbitrary targets such as a date of 2050, which was concocted simply because it was a good end point as a date. There’s no scientific rationale for choosing 2050 as the point to which we should reach net zero.”

    Leon Simons (looking up)

    “The Greenhouse Gas CO₂ equivalent concentration is now about 573 ppm.

    Which would take 206% of preindustrial CO₂!

    That's a stronger GHG forcing change than occured between the Last Glacial Maximum (LGM, when global sea levels were ~130 meters lower than today) and 1750!”

    Vzhledem k tomu, že 10% je 800 000 nejbohatších, tedy v podstatě s velkou pravděpodobností i my všichni (třeba každý druhý na Západě?) se obávám, že to může být i pravda.
