    Maybe it’s methane release. Maybe it’s gasses from the sea floor we knew nothing about. We have no fucking clue what climate change is going to look like. PR firms told scientists to put the lowest projections in press releases for the last decade. The real numbers are both grim and proving to be optimistic.

    As it turns out, the math was all wrong. Who knows why? Maybe all the Earth’s various systems are interrelated, and when one system collapses it causes dozens of other systems to collapse. Maybe Earth and the delicate balance that enabled life to grow on this planet is a little more sensitive to sudden, radical change than we thought.

    Maybe all the people who lied about climate change since the 1970s lied about more shit we’re going to find out about shortly now that we can’t stop it from happening. But they’ll still make their profits and get their taxpayer-funded subsidies, so capitalism is working as intended.

      Gasses from the sea floor

      It’s kind of crazy to me how what felt like yesterday they were like oh yeah, let’s see how bad dredging is? Oh it’s the equivalent of the aviation industry…

      We have had very smart people working on climate change models for decades and no one ever looked into that? Or has dredging increased so much recently that it was barely a factor before?

        We have had very smart people working on climate change models for decades and no one ever looked into that?

        The problem isn’t that no one has looked into it. The problem - and this is a general one for any scientist working in climate change or environmental protection - is that we can’t afford to raise a single false alarm. We can’t publish bad news unless we’re 100% certain, because that will give oil companies’ lawyers and ‘journalists’ enough ammo for the next fifty years. This means that published climate predictions are usually the most optimistic and conservative estimates.

        It’s definitely increased a lot in the last few decades, as ships have gotten insanely huge.

    This is the best summary I could come up with:

    The largest ever recorded leap in the amount of carbon dioxide laden in the world’s atmosphere has just occurred, according to researchers who monitor the relentless accumulation of the primary gas that is heating the planet.

    “It’s really significant to see the pace of the increase over the first four months of this year, which is also a record,” said Ralph Keeling, director of the CO2 Program at UC San Diego’s Scripps Institution of Oceanography.

    In June, the National Oceanic and Atmospheric Administration announced that global concentration of CO2 had hit 421ppm, a 50% increase on pre-industrial times and the highest in millions of years.

    The rapid rise in the heat-trapping gas threatens the world with disastrous climate breakdown in the form of severe heatwaves, floods, droughts and wildfires.

    Recent research has suggested that CO2 levels were last this high around 14m years ago, causing a climate that would appear alien to people alive today.

    The previous record annual rise in CO2 took place in 2016, amid another El Niño event, which temporarily causes a spike in global temperatures.

    My guess, Russias war, Israels war, Chinas coal burning for electricity so we can have cheap stuff to throw away imeadiatelly after using it once.
