    Major reversal in ocean circulation detected in the Southern Ocean, with key climate implications | Institut de Ciències del Mar
    https://www.icm.csic.es/en/news/major-reversal-ocean-circulation-detected-southern-ocean-key-climate-implications?

    “We are witnessing a true reversal of ocean circulation in the Southern Hemisphere—something we’ve never seen before,” explains Antonio Turiel, ICM-CSIC researcher and co-author of the study. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the SMOC is not just weakening, but has reversed. This could have unprecedented global climate impacts.”

    According to the research team, the consequences of this reversal are already becoming visible. The upwelling of deep, warm, CO₂-rich waters is believed to be driving the accelerated melting of sea ice in the Southern Ocean. In the long term, this process could double current atmospheric CO₂ concentrations by releasing carbon that has been stored in the deep ocean for centuries—potentially with catastrophic consequences for the global climate.

    “The new processor has allowed us to obtain surface salinity data of unprecedented quality in this region,” explains Verónica González. “Thanks to this improvement, we can now provide a coherent explanation for the rapid Antarctic sea ice loss that had puzzled the scientific community.”

    ‘A war of the truth’: Europe’s heatwaves are failing to spur support for climate action | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2025/jul/04/europe-heatwaves-failing-support-climate-action

    As heatwaves engulfed large swathes of Europe and North America last week – the latest in a stream of deadly extremes made worse by fossil fuel pollution – green groups are frustrated that increasingly violent weather has not spurred the urgent support for climate action they had expected.

    Governments across the rich world continue to roll back policies to stop the planet from heating, while far-right parties that deny climate science lash out at environment rules even as disasters unfold. Their voters, while rarely climate deniers themselves, seem to tolerate their energetic attacks on environmental policy, if not support them.

    S předpokladem, že další zrychlení nebude probíhat.
    A dává smysl vzhledem k tomu, že přes 50% všech emisí bylo emitováno za posledních ~40 let a efekt kdy se emise projeví (carbon lag) zabere nějakých 30 let.

    Burning wood for heat emits more CO₂ than coal - BirdLife International
    https://www.birdlife.org/news/2025/07/02/too-hot-to-handle-burning-wood-for-heat-emits-more-co%e2%82%82-than-coal/

    Climate impact: Burning biomass releases significant greenhouse gases, especially when the loss of forest carbon sinks is taken into account. This means that bioenergy, especially from forests, can be more polluting than the fossil fuels it’s meant to replace.

    Resource limitation: There isn’t enough sustainable biomass to meet Europe’s growing demand. Bioenergy competes with land needed for food, materials like wood products, and biodiversity.

    Economic risks: As demand rises but supply stays limited, energy prices may increase, threatening affordability for households and stability for industries.

    Health impacts: Burning wood and other biomass produces fine particulate matter, contributing to air pollution and associated health risks.

    Reduced ecosystem services: Harvesting biomass reduces biodiversity and the ability of natural ecosystems to provide essential services like clean water, fertile soil, and climate regulation.

    Více elektřiny z obnovitelných zdrojů než z uhlí vyrobilo v červnu Polsko. Zelená energie činila 44,1 procenta energetického mixu v zemi. Poprvé tak překonala uhlí, které kleslo na 43,7 procenta. Zbytek tvořil zemní plyn. Data zpracoval varšavský energetický think-tank Forum Energii, vychází z údajů polského provozovatele energetické sítě.

    Political cowardice hindering Europe’s climate efforts, says EU’s green chief | Extreme weather | The Guardian
    https://www.theguardian.com/world/2025/jul/02/political-cowardice-hindering-europe-climate-efforts-eu-green-chief-teresa-ribera

    Speaking alongside Jessika Roswall, the EU commissioner for environment, water resilience and a competitive circular economy, Ribera said there was still a long way to go when it came to readying infrastructures and urban environments for the realities of the emergency.

    A major part of the problem, she added, was that some political parties “continue to insist, quite vehemently, that climate change does not exist”, or else say that taking decisions to adapt to environmental realities is too expensive.
