    Emise, sucho, odpady. Česko lije peníze do ekologie, ale vidět to není - Seznam Zprávy

    Životní prostředí České republiky je hodnoceno jako páté nejhorší v Evropské unii. Ačkoliv se v Česku do jeho ochrany investuje 2,7 procenta HDP (přičemž unijní průměr činí 1,8 procenta), stále se potýkáme se suchem a vysokými emisemi skleníkových plynů. Podprůměrně si Češi vedou i v omezování produkce komunálního odpadu, navíc se nám příliš nedaří odpad recyklovat.

    Při srovnání unijních zemí, které v rámci projektu Index prosperity připravila Česká spořitelna společně s portálem datové žurnalistiky Evropa v datech, vstupovalo do hry celkem 14 indikátorů. Vedle výše i níže jmenovaných to dále byly například spotřeba vody, plocha země pokrytá lesy nebo podíl obnovitelných zdrojů na produkci elektřiny. Česká republika se pak v souhrnu zařadila až na 23. místo z 27 zemí EU.

    Saudi Arabia -- the world's biggest oil exporter -- took a hardline stance, saying it would "absolutely not" agree to phasing down fossil fuels, let alone phasing them out.
    This came despite scientists warning Tuesday that global warming could breach the 1.5C limit within seven years.
    The thorny debate over the future of fossil fuels, the largest contributor to global warming, is the key battleground at the COP28 meeting hosted by the oil-rich United Arab Emirates.

    COP28 president Sultan Al Jaber has urged governments to agree on global goals to triple renewables capacity and double the rate of energy efficiency improvements by 2030.

    This call from Al-Jaber is supported by the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA), and political momentum is building.

    This month, a US-China joint statement on climate change backed tripling renewables to substitute coal, oil and gas power and bring about “post-peaking meaningful absolute power sector emission reduction”.

    The context for these targets is a world that remains dramatically off course against global climate goals, with recent assessments pointing to warming of 2.4-2.7C above pre-industrial levels by 2100.

    In its recent report on how to get back on track, the IEA said tripling renewables, doubling efficiency and slashing methane emissions 75% by 2030 would provide 80% of the emissions cuts needed for 1.5C.

    TUHO: Based on current climate policies around the world, various groups estimate that we’re now on track for around 2.5°C (4.5°F) global warming by 2100.

    On the one hand, that’s not yet good enough to meet the target set in the Paris agreement. On the other hand, climate policies and clean technologies deployed over just the past eight years have already erased a full degree Celsius of global warming from the future world in 2100. Governments need to do more in the coming years to bring the Paris goals within reach, but the progress made over just the past eight years has been remarkable, especially in comparison to the prior decades of futility.

    Challenges and opportunities for climate policy integration in oil-producing countries: the case of the UAE and Oman

    In the context of international climate change obligations, Gulf Arab states have introduced policies to integrate climate policies into economic development and planning, seeking to maximize clean development opportunities yet at the same time to minimize the threats to their rentier economies caused by sudden shifts away from fossil fuels. This paper assesses the challenges and opportunities for climate policy integration in the Gulf states of the United Arab Emirates (UAE) and Oman, examining the interaction between their climate policy and their political–economic regimes. It adopts a novel analytical framework that integrates insights from climate policy integration and the political–economic theory of rentier states. Drawing on semi-structured interviews with key stakeholders and relevant policy documents, it reveals modest progress in integrating climate policy into economic development plans in the UAE but major impediments to climate policy integration in Oman. Both countries face significant shortfalls in climate-related financial and human resource capacities. Climate policy integration efforts have focused on the energy sector with the purpose of protecting rents from oil exports rather than advancing a low-carbon transformation of their economies. This has created structural ambiguity in the climate policy integration advanced in the UAE and Oman.

    Great-power politics, order transition, and climate governance: insights from international relations theory

    The complex politics of climate change cannot be properly understood without reference to deeper geopolitical trends in the wider international system. Chief among these is the growing resurgence of ‘great-power politics’ between China and the US, along with failures of socialization and enmeshment into global governance structures in relation to these two powers. Traditional theoretical frameworks have failed to adequately account for these developments. Nonetheless, this current great-power contestation is at the core of an order transition that has prevented the large-scale institutional redesign required to remove deadlocks in existing global governance structures, including climate governance. Examples from the 2009 Copenhagen Climate Change Conference provide ample evidence for these claims. The slow progress of the climate change negotiations are due not just to the politics of the issue itself, but to the absence of a new political bargain on material power structures, normative beliefs, and the management of the order amongst the great powers. Without such a grand political bargain, which could be promoted through a forum of major economies whose wide-ranging remit would go beyond single issues, the climate change regime is only ever likely to progress in a piecemeal fashion.

    Heroes of Environmental Diplomacy
    Profiles in Courage

    Today more than ever, when the world is beset by environmental, social, healthcare and economic challenges, we need courage in our politics, both nationally and globally. This book tells the stories, some for the first time, of twelve individuals who made heroic contributions to protecting our planet through ground-breaking international treaties.

    Can individuals change the world? Today, when impersonal forces and new technologies seem to be directing our lives and even our entire planet in ways we cannot control, this question feels more relevant than ever before. This book argues that we can all make a difference. It tells inspiring stories of individuals who have had a global impact that is beyond dispute, as well as others who have brought about change that is understated or hard to measure, where the scale of the impact will only become clear in years to come. While some are scientists, others are politicians, diplomats, activists, and even businesspeople. However, they all share the qualities of perseverance, patience, a willingness to innovate or try new approaches, and the endurance to continue over years, even decades, to pursue their goal. Drawing on interviews and the inside stories of those involved, each chapter follows one or more of these heroic individuals, a list which includes Luc Hoffmann, Mostafa Tolba, Maria Luiza Ribeiro Viotti, Raul Oyuela Estrada, Barack Obama and Paula Caballero.

    Presenting an uplifting and gripping narrative, this book is an invaluable resource for students, scholars, activists and professionals who are seeking to understand how consensus is reached in these global meetings and how individuals can have a genuine impact on preserving our planet and reinforcing the positive message that global cooperation can actually work.

    Kemp, L., Xu, C., Depledge, J., Ebi, K. L., Gibbins, G., Kohler, T. A., Rockström, j., Scheffer, M., Schellnhuber, H. J., Steffen, W., & Lenton, T. M. (2022). Climate Endgame: Exploring catastrophic climate change scenarios. Proceedings of the National Academy of Sciences, 119(34), e2108146119.

    Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for climate change, such potential futures are poorly understood. Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. Analyzing the mechanisms for these extreme consequences could help galvanize action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the likelihood of extreme climate change, discuss why understanding bad-to-worst cases is vital, articulate reasons for concern about catastrophic outcomes, define key terms, and put forward a research agenda. The proposed agenda covers four main questions: 1) What is the potential for climate change to drive mass extinction events? 2) What are the mechanisms that could result in human mass mortality and morbidity? 3) What are human societies' vulnerabilities to climate-triggered risk cascades, such as from conflict, political instability, and systemic financial risk? 4) How can these multiple strands of evidence—together with other global dangers—be usefully synthesized into an “integrated catastrophe assessment”? It is time for the scientific community to grapple with the challenge of better understanding catastrophic climate change.
