    90% of earths topsoil is at risk of depletion by 2050

    Global freshwater demand will exceed supply 40% by 2030

    Global human population has surpassed Earth’s sustainable carrying capacity.

    Global carbon emissions are still rising

    The world is likely to exceed a key global warming target soon but the earths alebedo with the declining sea ice and lack of cloud cover will impact these numbers massively and isn’t being predicted for, which means that 4.5c above the baseline by 2060 is now possible.

    Oh and this El Nino is so powerful the fucking graph needed to be made bigger today and all of the above is and will continue to be impacted by this as it progresses.

    So yeah, unless we can somehow rapidly evolve physics defying magic to handwave all our problems away before basically everything dies, basically everything will die.

      You can put quite a lot of nines after the decimal point if more than 99% of people die without humanity reaching its lowest population in history, so the post you’re replying to is right that humans are likely to persevere, and knowing humans, there’s a good chance that if industrial civilisation starts again (which is less likely - you need lots of accessible cheap coal to make it worth putting up with rudimentary steam engines long enough to develop good ones), lessons won’t be learned and we’ll pollute ourselves to death again.

        2 people arent enough. Who is going to repopulate the Earth? Elon Musk? With what? His male buddies? They going to invent male pregnancy?

          2 isn’t.

          You’d need about 50 for a healthy diversity of genes.

          But that is still only 0.00000055% of the current population

        With no soil to grow food in and a climate too hot and unstable to support crop growth, we’re not going to be persevering for very long.

            Cool cool, so what are we going to eat then?

            With all the pollinators dying off over the next +1.5c, and 90% of the top soil depleted by 2050, and ever more erratic climates world wide, plants will not grow.

            The oceans will very soon be so hot and acidic that the phytoplancton at the base of the oceans ecosystem, will dissolve. So sea food isn’t going to be an option either.

            Oooh, maybe animals on land, right? Well, yeah no, without crops livestock is unsustainable and considering humans and livestock currently makes up 95% of the worlds mammal biomass and the remaining 5% can’t survive without food… looks like that’s not going to be an option for feeding the ‘persevering’ either.

              Life finds a way.

              Even if 99.999999% of the population dies out, humans will still survive. (I calculated that percentage)

              Other animals will adapt to those acidic oceans.

              Plants will still survive, not all edible, but so was most of the plants we ate during the ice age.

              Even if we have to go back to the stone age, we will survive.
