  1. What's the worst situation, for the future children will find a horrible world 😢. In my case, I'm reusing plastics as much as I can. And I take care my garden. It's not too much but at least is a small step

  2. On one part I am concerned on how ocean carbon capture can be problematic in the same sense as atmospheric carbon capture. But at the same time, it seems to be something that can buy vulnerable coral and reef populations enough time to live through climate change (so that we don't permanently lose them). I can imagine implementing such technologies, on say, the Great Barrier Reef. Hopefully this promising technology comes to fruition and hopefully it doesn't introduce more problems than solutions.

  3. Hahahahaha 😂🤣 yeah Australias great barrier Reef is dying. Then how come the reef is bigger than in decades. These scientists are making to much 💸 from climate change to look too hard.

  4. …and came along carbon credits 🙄
    Extending the life of the fossil fuel industry by financing climate change initiative policy funding. What a load of tax write-off that is.

  5. total BUNK. variation in ocean pH caused by global CO2 raise is negligible. Natural, more acid CLEAN rain, affects pH WAY more than CO2 absorption. This is pseudo-science in the service of crushing western prosperity, an act of warfare driven by the WEF/UN and those nations and crony economic opportunistic parasites who finance them.

  6. a 40% increase in acidity corresponds only to 0.15 pH decrease, which is inconsequential over the period of time it happens. Clean rain changes pH more than that. Again, journalists use the most sensational, and irrelevant presentation of data. this is blatant intellectual dishonesty, driven by some ideological agenda. We are fed up if being treated as children, as human cattle to be husbanded.

  7. These videos are nothing but scaremongering to increase funding for these people.
    Firstly, it's a slight reduction in alkalinity rather than rising acidification.
    So much BS is thrown at innocent people who inadvertently become victims of this propaganda.

  8. Coral reefs produce 50% of the world's oxygen while covering only . 0025% of the ocean floor. We are destroying our Earths lungs along with 20% of oxygen from rain forests that are being destroyed at alarming rates…………….we are destroying an ecosystem that is eliminating 70% of our atmosphere's oxygen……….I don't think I need to tell you what means for the survival of all species on this planet.

  9. Vers un océan émetteur de CO2 ?

    « Le résultat était tellement surprenant que je pensais avoir fait une erreur », confie Jonathan Lauderdale. Son modèle indiquait en effet que, lorsque les concentrations de ligands varient d'une région de l'océan à l'autre, alors, plus la circulation océanique est faible, plus le CO2 s'accumule dans l'atmosphère. L'ennui, c'est qu'il s'avère que dans le monde réel, les concentrations en ligands changent effectivement d'une région de l'océan à l'autre.

    Les chercheurs expliquent. Alors que la circulation océanique ralentit sous l'effet du réchauffement climatique, l'océan extrait moins de carbone et de nutriments de ses profondeurs. Résultat, le phytoplancton de surface manque de ressources. Il produit alors moins de ligands. Et qui dit moins de ligands, dit aussi moins de fer disponible et donc… moins de phytoplanctons pour absorber le CO2 de l'atmosphère. Le tout dans ce que les scientifiques appellent une boucle de rétroaction. Plus communément, un cercle vicieux.

    « Certains modèles climatiques prédisent un ralentissement de 30 % de la circulation océanique en raison de la fonte des calottes glaciaires, notamment autour de l'Antarctique. Cet énorme ralentissement de la circulation pourrait devenir un gros problème : en plus d'une foule d'autres problèmes climatiques, non seulement l'océan absorberait moins de CO2 anthropique de l'atmosphère, mais cela pourrait être amplifié par un dégazage net de carbone des profondeurs océaniques entraînant une augmentation inattendue du CO2 atmosphérique et un réchauffement climatique supplémentaire », conclut Jonathan Lauderdale.

  10. This complete and utter garbage. Just an other bedtime story to scare the kids. The real problem humanity faces are the scores of gullible people who believe everything they see on tv or in this case youtube
