    "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.

    Wealthy countries lead in new oil and gas expansion, threatening 12bn tonnes of emissions | Oil and gas companies | The Guardian
    https://www.theguardian.com/environment/article/2024/jul/24/new-oil-gas-emission-data-us-uk

    The new oil and gas field licences forecast to be awarded across the world this year are on track to generate the highest level of emissions since those issued in 2018, as heatwaves, wildfires, drought and floods cause death and destruction globally, according to analysis of industry data by the International Institute for Sustainable Development (IISD).

    The 11.9bn tonnes of greenhouse gas emissions – which is roughly the same as China’s annual carbon pollution – resulting over their lifetime from all current and upcoming oil and gas fields forecast to be licensed by the end of 2024 would be greater than the past four years combined. The projection includes licences awarded as of June 2024, as well as the oil and gas blocks open for bidding, under evaluation or planned.

    Swiss lawmakers reject climate ruling in favour of female climate elders | Switzerland | The Guardian
    https://www.theguardian.com/world/article/2024/jun/12/swiss-lawmakers-reject-climate-ruling-in-favour-of-female-climate-elders

    A panel of Strasbourg judges ruled in April that Switzerland had violated the human rights of older women through weak climate policies that leave them more vulnerable to heatwaves. Activists hailed the judgment as a breakthrough because it leaves all members of the Council of Europe exposed to legal challenges for sluggish efforts to clean up carbon-intensive economies.

    But the Swiss parliament’s lower house voted on Wednesday to disregard the ruling – with 111 votes in favour and 72 against – arguing that the judges had overstepped their bounds and that Switzerland had done enough. The declaration, which has been adopted by the upper house but does not bind the federal government, accused the court of “inadmissible and disproportionate judicial activism”.

    SHEFIK: i jaro není co bývalo

    India saw a 55% rise in deaths due to extreme heat between 2000-2004 and 2017-2021, a recent study published in the medical journal, The Lancet, has found.

    Exposure to heat also caused a loss of 167.2 billion potential labour hours among Indians in 2021, the study noted.

    This, it adds, resulted in loss of incomes equivalent to about 5.4% of the country's GDP.

    India has faced increasingly intense heatwaves in recent years.

    Extreme Sahel heatwave that hit highly vulnerable population at the end of Ramadan would not have occurred without climate change – World Weather Attribution
    https://www.worldweatherattribution.org/extreme-sahel-heatwave-that-hit-highly-vulnerable-population-at-the-end-of-ramadan-would-not-have-occurred-without-climate-change/

    Extreme temperatures were reported across the Sahel, including in Senegal, Guinea, Mali, Burkina Faso, Niger, Nigeria and Chad. In many of these countries power cuts occurred during the heat episode, making it especially difficult for the population to cope with the extreme temperatures.

    Heatwaves are arguably the deadliest type of extreme weather event and while the death toll is often underreported and not known until months after the event, a surge in hospital admissions and deaths were reported from the Gabriel Touré hospital in Bamako, Mali between 1-4 April (Bahati, 2024).

    The hospital recorded 102 deaths over the four-day period, which is significantly more than expected – in April 2023, the hospital recorded 130 deaths over the entire month (JolibaFM, 2024). While statistics for the cause of death have not been reported, around half were over the age of 60, and the hospital reports that heat likely played a role in many of the deaths. Furthermore, up to 44 bodies were buried in one cemetery in Bamako on Friday 5 April after the weekly service (DW 2024).

    ...

    To estimate the influence that human-caused climate change has had on the extreme heat since the climate was 1.2°C cooler, we combine climate models with observations. Observations and models both show that heatwaves with the magnitude observed in March and April 2024 in the region would have been impossible to occur without the global warming of 1.2°C to date.

    Two new Mexico teams to explore impacts of SRM on heatwaves and biodiversity loss - The DEGREES Initiative
    https://www.degrees.ngo/two-new-mexico-teams-explore-srm-heatwaves-and-biodiversity-loss/

    By modelling the potential impacts of SRM and climate change, these scientists will contribute to an evidence base that policy makers in Mexico and Central America can use to make informed decisions about reducing climate risks. This is research conducted by Latin Amercian scientists working at a Mexican University, who will communicate their findings openly to key stakeholders through peer-reviewed academic publications.

    Last year, Mexico announced an intention to ban outdoor solar geoengineering activities after an American start-up company attempted a small-scale SRM balloon test on Mexican territory.

    Unlike that controversial small-scale for-profit ‘deployment’, the two new Degrees-funded scientific teams will conduct responsible computer-based modelling research on the potential effects of SRM on climate change, heatwaves, and biodiversity. This supports Degrees’ central mission – while we take no position on whether SRM should ever be used, we want developing countries to have the capacity to do their own research and to have an informed role in any future governance discussions and decisions on its use or non-use.

    Minsky moment: are pension assets at risk due to flawed climate analysis? | Netzeroinvestor
    https://www.netzeroinvestor.net/news-and-views/are-millions-of-pensions-at-risk-due-to-flawed-climate-analysis

    Widespread reliance on flawed research generates a disconnect between current investment decision making, which assumes relatively trivial impacts from climate change, and the likely real-world effects of global warming, Keen warned.

    "To ensure that the world moves into a new climate secure energy system, it’s crucial pension schemes send the market the right investment signals,” said Mark Campanale, the founder of Carbon Tracker.

    “The signal has to be that a swift, orderly transition is in everyone’s financial interests, particularly for scheme beneficiaries.”

    However, the relationship between economics, climate science and assessing financial risk is not a “comfortable one,” he continued, adding that “the advice pension schemes are receiving risks trivialising the potentially huge damage climate change will have to asset values."

    Campanale stressed that “these flawed climate risk models” are used throughout the financial system, lulling economic decision makers, from pension funds to central banks, into a false sense of security.

    “The result is cavalier positions such as US Federal Reserve Board Governor Christopher Waller who announced: ‘Climate change is real, but I do not believe it poses a serious risk to the safety and soundness of large banks or the financial stability of the United States’,” he said.

    The report issues a direct warning to asset owners for the serious prospect of an “unpleasant, abrupt and wealth destroying” so-called “Climate Minsky moment” with a sudden collapse in asset values as financial markets wake up to the gap between mainstream economist forecasts and the reality of climate impacts.

    Keen, who is also the former head of the School of Economics, History and Politics at Kingston University, London, contrasts scientists’ empirical research with predictions by climate economists that are “a ‘hunch’ based on rather spurious assumptions for global warming, which have been used to generate equally spurious estimates of damages to future GDP.”

    He underscored that global warming, at less than 1.5°C, is already affecting people and companies across the planet, pointing at record heatwaves, floods, and intensifying storms as they halt commerce, damage crops, create uninsurable areas, and impair infrastructure.

    Keen singled out scientific research which finds that exceeding the 1.5°C Paris target would be “dangerous”, passing 3°C would be “catastrophic”, and reaching 5°C will be “beyond catastrophic, raising existential threats”.

    Yet, despite scientific predictions, a survey of 738 climate economics papers in a number of top academic journals found the median prediction of economists was that 3°C of warming would reduce global GDP by just 5%, and warming of 5°C would see a 10% reduction.

    ...

    The researchers singled out investment managers and consultants such as Aon Hewitt, Hymans Robertson and Mercer as they "continue to rely on flawed research" when they advise pension funds on the impacts of global warming on members’ portfolios.

    For example, Mercer, in advice to Australian fund HESTA predicts only a -17% portfolio impact by 2100 in a 4°C scenario. It states that its model primarily reflects coastal flood damage and does not take account of climate tipping points.

    Mercer also advises LGPS Central, which manages £28.5 billion of retirement savings for a million members of Local Government Pension Schemes in the UK.

    One of these schemes, Shropshire County Pension Fund, told members that a trajectory leading to 4°C by 2100 would only reduce annual returns by 0.06% in 2030 and 0.1% by 2050, saying that it relied on LGPS Central for information.

    Moreover, in a 2022 report, Australian superannuation firm Unisuper concluded that even in a “worst case scenario” involving a 4.3°C increase in global temperatures by 2100, “the overall risk to our portfolio is acceptable.”

    “Each layer in the process of assessing the risks of climate change has assumed that the previous layer has done its job adequately, and has relied on the previous layers reputation, rather than scrutiny of the work undertaken," explained Professor Keen.

    “Pension funds rely upon consultants because of their reputation in the field; consultants rely upon academic economists, because their papers had passed academic refereeing,” he added.

    “The final impact is a series of flawed economic assumptions informing pensions’ decision making.”

    The urgent question now is: how can we put the climate crisis back at the top of the agenda, for politicians and the public alike? The first step is to recognise that climate fatigue in Europe has little to do with Europeans being less concerned about the impact of volatile climate systems. Indeed, people feel the effects directly and terrifyingly as the continent is increasingly battered by heatwaves, wildfires, storms and floods.

    But people are also terrified of what they believe will be the cost to individuals of the required energy transition. According to the consulting firm McKinsey, the global transition to net zero will require additional investments in fixed assets of $3.5tn a year until 2050. That’s about a quarter of all the tax raised worldwide. There is still no convincing mechanism for financing this in ways that reassure families, individuals, small firms and farmers that they are not going to be bankrupted. Increasingly, ordinary citizens know that many of them will have to foot crippling bills for such things as renovating homes to make them comply with energy efficiency rules.

    The snow crab is an iconic species in the Bering Sea that supports an economically important fishery and undergoes extensive monitoring and management. Since 2018, more than 10 billion snow crab have disappeared from the eastern Bering Sea, and the population collapsed to historical lows in 2021. We link this collapse to a marine heatwave in the eastern Bering Sea during 2018 and 2019. Calculated caloric requirements, reduced spatial distribution, and observed body conditions suggest that starvation played a role in the collapse. The mortality event appears to be one of the largest reported losses of motile marine macrofauna to marine heatwaves globally.

    ‘We’re not doomed yet’: climate scientist Michael Mann on our last chance to save human civilisation | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2023/sep/30/human-civilisation-climate-scientist-prof-michael-mann

    So it’s a question of how bad we’re willing to let it get,” he says. “1.5C is already really bad but 3C is potentially civilisation-ending bad.”

    Widespread heatwaves, wildfires and floods clearly linked to global heating have given urgency to the call for action, Mann says: “But urgency without agency just leads us towards despair and defeatism. That’s what the polluters would like, to take all those climate activists and move them from the frontlines to the sidelines.”

    Ending the climate emergency is possible, Mann says: “We know that the obstacles to keeping warming below catastrophic levels are not yet physical and they’re not technological – they’re political. But there’s some pretty big political obstacles right now.”

    “Here at Penn State, there’s so much anxiety, fear and despair, and grief even,” he says. “Some of it comes from the mistaken notion that it’s physically too late and I want to dispel that notion. But part of it comes from an understandable cynicism about our politics, and that’s a much bigger challenge.”

    ...

    The UN’s major climate summit, Cop28, begins at the end of November and is being hosted by the United Arab Emirates, which Mann calls “very disturbing”. The UAE has the third biggest net zero-busting plans for oil and gas expansion in the world and the president of Cop28 is also the CEO of Adnoc, the UAE’s state oil company

    “It just feels wrong to allow them to adopt the imprimatur of global climate action by hosting Cop28,” Mann says. “It is legitimising behaviour on their part and on the part of other petro states that is fundamentally at odds with the task we have ahead. I find it very disturbing.”

    Mann has been a top target of climate deniers since the publication of the hockey stick chart. He is scathing about Elon Musk’s running of the social media platform X, formerly called Twitter.

    “Musk used to be held out as an environmental hero, because of his role with Tesla,” Mann says. “But increasingly, he’s shown his true colours, his political allegiance to Trump and fascism.”

    “Twitter was a global public square, a forum for communicating about the climate crisis,” he says. “What Musk has done is turn it into a toxic forum for the promotion of climate denialism and everything that’s bad in the world. It’s stunning.” Mann noted that Prince Alwaleed bin Talal of Saudi Arabia, one of the “worst petro state actors”, played a $1.9bn role in Musk’s purchase of Twitter.

    Mann also pointed out that Prince Alwaleed was a key backer of Rupert Murdoch’s media empire until 2017. “Rupert Murdoch has weaponised his global media network for the promotion of climate denialism and to attack renewable energy, which plays to his ideology and to the interests of some of the powerful petro-states, specifically Saudi Arabia.”

    Deadly humid heatwaves to spread rapidly as climate warms – study | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2023/sep/08/deadly-humid-heatwaves-to-spread-rapidly-as-climate-warms-study

    The research analysed data from thousands of weather stations across the world to show that 4% had already experienced at least one six-hour period of this extreme heat stress since 1970, with the frequency of such events doubling by 2020. However, these have been confined to date to hot places, including the Gulf in the Middle East, the Red Sea and the North Indian Plain, where people expect extreme heat.

    The analysis, which also used climate models, shows that extreme heat stress will spread rapidly to other regions with global heating of only 2C. The climate crisis has already raised global temperatures by about 1.2C. At 2C, more than 25% of the weather stations would suffer the extreme heat stress once a decade on average.

    The east coast and midwest regions of the US and central Europe, including Germany, are among places that would experience the arrival of unprecedented heat stress conditions. In places that are already hot, like Arizona, Texas and parts of California, periods of extreme heat stress would become annual events at 2C.

    TUHO:

    In August 2021, UNICEF warned that over one billion children are at extreme risk of the impacts of AGW [161]. According to the Children’s Climate Risk Index (CCRI) [161],
    240 million children are exposed to coastal flooding;
    330 million to riverine flooding;
    400 million to cyclones;
    600 million to vector borne diseases;
    815 million to lead pollution;
    820 million to heatwaves;
    920 million to water scarcity and
    one billion children to dangerously high levels of air pollution.
    Looking at the problem from different perspectives provides convergent evidence for an estimate of 1 billion deaths at 2 °C of warming:
    The estimate corresponds to 10% of the projected future world population. All 10 billion humans will need food and fresh water to survive, and AGW will seriously affect both.
    Since CO2 stays in the atmosphere for about a century, the prediction implies that, on average, 10 million additional deaths per year will be due to AGW.
    If the wet-bulb temperature exceeds skin temperature, perspiration can no longer cool the body. Already in 2022, this effect was life-threatening for a billion people in India and Pakistan [162]. In the same countries in 2023, maximum temperatures were consistently above 40 °C for over two weeks [161].

    What is playing out all over the world right now is entirely consistent with what scientists expect. No one wants to be right about this. But if I’m honest, I am stunned by the ferocity of the impacts we are currently experiencing. I am really dreading the devastation I know this El Niño will bring. As the situation deteriorates, it makes me wonder how I can be most helpful at a time like this. Do I keep trying to pursue my research career or devote even more of my time to warning the public? The pressure and anxiety of working through an escalating crisis is taking its toll on many of us.

    As Beijing swelters, activists hope the heat will prompt climate action | China | The Guardian
    https://www.theguardian.com/world/2023/jun/30/as-beijing-swelters-activists-hope-the-heat-will-prompt-climate-action

    although there is some limited education about climate change, permitted discourse stops short of talking about major policy shifts, such as reducing China’s coal emissions more rapidly. The government has pledged to become carbon neutral by 2060, but concerns about energy security and the need for economic growth mean that local authorities are showing no sign of backing down on building new coal power.

    Also, says Zhao, “even if people link heatwaves and climate change, they don’t think it’s something that the individual should pay attention to.” Most people see it as being the government’s responsibility – and therefore out of the hands of the public, she says.

    Still, awareness of climate change, and discussion about how it can be managed, is ticking up. The topic is increasingly discussed in state media. Analysis by Sixth Tone, a state-backed outlet, found that mentions of key words relating to climate change jumped from about 750,000 in 2019 to nearly 3.3m in 2021.

    Surveys suggest that, compared with the US, a slightly higher proportion of Chinese people accept that climate change is happening and that it is caused by human activity.

    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.
