    Out today in @nature our new paper showing how meltwater increases around Antarctica are set to dramatically slowdown the Antarctic overturning circulation, with a potential collapse this century. A🧵on how this work came about and what we found.

    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.

    Last Generation climate change activists to stand trial at the Vatican
    https://religionnews.com/2023/05/22/last-generation-climate-change-activists-to-stand-trial-at-the-vatican/

    Dva italští klimatičtí aktivisté, kteří se přilepili k podstavci jedné z nejznámějších starořímských soch ve Vatikánských muzeích, musí zaplatit téměř 30 000 eur (přes 713 000 korun). Informovala o tom v pondělí agentura Reuters s odkazem na rozhodnutí vatikánského trestního soudu. Dvojice podle něj poškodila sousoší Láokoón a jeho synové.

    Uhlíkové clo může klima zlepšit. Výnosy však musí jít zpět na zelenou tranzici třetích zemí - VOXPOT

    Nové nařízení EU - uhlíkové clo (CBAM) | Deloitte Česká republika
    https://www2.deloitte.com/cz/cs/pages/legal/articles/cbam.html?

    Takzvané emisní povolenky se v Česku, ale ani v jiných státech Unie, velké oblibě netěší. Jde přitom o klíčový nástroj evropské klimatické politiky.
    Tím se má nově stát také CBAM neboli uhlíkové clo. Jak mohou oba mechanismy pomoci v boji s klimatickými změnami?

    Uhlíkové trhy se časem rozrostly po celém světě i díky vysoké efektivitě nástroje, která částečně vysvětluje popularitu tohoto mechanismu oproti uhlíkové dani.

    I díky tomu bylo v roce 2022 asi 17 % světových emisí pokryto systémem, který zpoplatňuje znečištění ovzduší uhlíkem: https://www.amo.cz/wp-content/uploads/2023/02/PROLIFERATING-CARBON-MARKETS-1.pdf

    „Jak se prohlubují důsledky změny klimatu, píšeme o něm stále častěji. A není pochyb, že tento trend bude pokračovat. Proto jsme se rozhodli, že nastal čas dát tématu zvláštní sekci, vysílá to totiž jasný vzkaz, že klima řadíme mezi nejdůležitější fenomény dnešní doby. A i pro nás samotné je to i závazek – odteď už nám žádná zásadní zpráva o klimatu, ale i obecně z environmentální oblasti, kterou do sekce rovněž řadíme, neunikne,“ přibližuje poslání nové sekce reportér zahraniční redakce Lukáš Marek, hlavní autor klimatické rubriky na Seznam Zprávách.
