    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "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.

    Efforts to assess risks to the financial system associated with climate change are growing. These commonly combine the use of integrated assessment models to obtain possible changes in global mean temperature (GMT) and then use coupled climate models to map those changes onto finer spatial scales to estimate changes in other variables. Other methods use data mined from 'ensembles of opportunity' such as the Coupled Model Intercomparison Project (CMIP). Several challenges with current approaches have been identified. Here, we focus on demonstrating the issues inherent in applying global 'top-down' climate scenarios to explore financial risks at geographical scales of relevance to financial institutions (e.g. city-scale). We use data mined from the CMIP to determine the degree to which estimates of GMT can be used to estimate changes in the annual extremes of temperature and rainfall, two compound events (heatwaves and drought, and extreme rain and strong winds), and whether the emission scenario provides insights into the change in the 20, 50 and 100 year return values for temperature and rainfall. We show that GMT provides little insight on how acute risks likely material to the financial sector ('material extremes') will change at a city-scale. We conclude that 'top-down' approaches are likely to be flawed when applied at a granular scale, and that there are risks in employing the approaches used by, for example, the Network of Central Banks and Supervisors for Greening the Financial System. Most fundamental, uncertainty associated with projections of future climate extremes must be propagated through to estimating risk. We strongly encourage a review of existing top-down approaches before they develop into de facto standards and note that existing approaches that use a 'bottom-up' strategy (e.g. catastrophe modelling and storylines) are more likely to enable a robust assessment of material risk.

    As the ice melts, a perilous Russian threat is emerging in the Arctic | Barry Gardiner | The Guardian
    https://www.theguardian.com/commentisfree/2023/jun/13/arctic-russia-nato-putin-climate

    The eight Arctic states – Canada, Finland, Denmark, Iceland, Norway, Sweden, the US and Russia – have long collaborated on scientific research through the Arctic Council, a non-military body. Until now. After Russia’s invasion of Ukraine, Arctic Council meetings ceased. So did cooperation with Russia. This has hampered progress on climate and environmental research and turbocharged the militarisation of the Arctic.

    The success of the Arctic Council depended on its geopolitical balance. It is not a security alliance and has always tried to remain independent from politics. Five of the eight countries were part of Nato; the other three were not. That has now changed. Finland joined Nato in April. Sweden is in the process of joining. Soon, Nato will literally be surrounding Russia in the Arctic.

    To understand why this matters, we must first understand the climate emergency taking place in the region. Summer sea ice has declined by 30% in the past 30 years; 90% of old ice, which is classified as five years old or more, has gone. That ice used to act as the great heat shield for the planet, reflecting back the sun’s rays. But the loss of ice is producing a vicious spiral of heating. The Arctic is now warming three times faster than the global average. This process is called Arctic amplification. It means that scientists now project an Arctic free from summer ice by 2040–45.

    As the ice cover is lost, a trans-polar route is opening to connect east Asia to Europe and the eastern coast of North America. And the ice barrier that once protected Russia’s northern shore will be exposed as never before. Russia represents 53% of the Arctic coastline and the need to protect its northern border as the ice barrier melts is a key national security concern.

    Vladimir Putin already had ambitious plans for the northern sea route, seeking to more than double the cargo traffic. But over the past six years, Russia has also built 475 military sites along its northern border. The port of Severomorsk, on the Kola peninsula, is the base of the country’s northern fleet. In recent years, the Russians have reactivated 50 Soviet outposts in the Arctic and equipped its northern fleet with nuclear and conventional missiles.

    The challenge of all this has not been purely logistical. As the permafrost thaws, the structural base for roads, buildings and other key infrastructure has collapsed. Russia is trying to deploy huge amounts of infrastructure and military capacity to build structures on land that is disintegrating, across roads that are disappearing

    ...

    On a recent visit to the Ny-Ålesund international research station on Svalbard, it was depressing to hear that scientific cooperation with Russia on climate matters has effectively ceased. The Arctic is an environment where cooperation is essential. Arctic science must be done over the long term, and the relationships and trust built up between partners offer predictability and greater stability. In a region that is becoming over-securitised, every opportunity to minimise accidental misunderstandings and avoid a military response should be seized.

    A militarised Arctic would undermine scientific cooperation and pose an existential threat. Somehow, we need a diplomatic effort to separate the politics of war from the imperatives of climate research.

    The global economic costs of climate change inaction - Oxford Economics
    https://www.oxfordeconomics.com/resource/the-global-economic-costs-of-climate-inaction/

    Our new damage function redefines the BHM damage function in terms of warming (that is, the change in global average temperature relative to pre-warming levels). Through this warming definition, it considers temperature anomalies from historical norms, which we show to be more economically consequential than average temperature levels. Our new damage function also accounts for volatility and extremes of the temperature distribution. The resulting estimates show that as the global warming goes beyond its current 1.1°C, productivity growth falls faster worldwide than previously estimated.

    Under this new specification, we find that 2.2°C of warming by 2050 has the potential to reduce global GDP levels by up to 20%. Warming of up to 5°C by 2100 would lead to economic annihilation, consistent with scientific research on mass extinction thresholds.

    It is also important to note that this estimation suggests that cooler countries, in contrast to BHM (Chart 1), no longer benefit from modest warming. Instead, all countries see significant losses in productivity growth from additional warming (Chart 2).

    Observationally-constrained projections of an ice-free Arctic even under a low emission scenario | Nature Communications
    https://www.nature.com/articles/s41467-023-38511-8

    Here we show, using an attribution analysis approach, that a dominant influence of greenhouse gas increases on Arctic sea ice area is detectable in three observational datasets in all months of the year, but is on average underestimated by CMIP6 models. By scaling models’ sea ice response to greenhouse gases to best match the observed trend in an approach validated in an imperfect model test, we project an ice-free Arctic in September under all scenarios considered. These results emphasize the profound impacts of greenhouse gas emissions on the Arctic, and demonstrate the importance of planning for and adapting to a seasonally ice-free Arctic in the near future.

    Sulfur emissions cooled our planet by about 0.5°C, on a global average.

    It cooled more where most of us live.

    3.5 years ago we reduced sulfur emissions over the oceans by about 80%.

    Oceans heat up faster.

    Prepare for more warming, extreme weather and faster sea level rise.

    Safe and just Earth system boundaries | Nature
    https://www.nature.com/articles/s41586-023-06083-8

    The stability and resilience of the Earth system and human well-being are inseparably linked1,2,3, yet their interdependencies are generally under-recognized; consequently, they are often treated independently4,5. Here, we use modelling and literature assessment to quantify safe and just Earth system boundaries (ESBs) for climate, the biosphere, water and nutrient cycles, and aerosols at global and subglobal scales. We propose ESBs for maintaining the resilience and stability of the Earth system (safe ESBs) and minimizing exposure to significant harm to humans from Earth system change (a necessary but not sufficient condition for justice)4. The stricter of the safe or just boundaries sets the integrated safe and just ESB.

    Our findings show that justice considerations constrain the integrated ESBs more than safety considerations for climate and atmospheric aerosol loading. Seven of eight globally quantified safe and just ESBs and at least two regional safe and just ESBs in over half of global land area are already exceeded. We propose that our assessment provides a quantitative foundation for safeguarding the global commons for all people now and into the future.
