I'm confused, what do you mean there's not going to be a future for them? No doubt there's going to be some challenges, but I thought all that carbon was in the atmosphere and oceans before it was sequestered by plants and alagae. I thought the major issue was the speed of change, but we really don't know what life is thing to do in response. According to this article, during the Cambrian, the earth was 10C hotter than it is today. https://news.climate.columbia.edu/2022/09/20/you-asked-dinosaurs-survived-when-co2-was-extremely-high-why-cant-humans/ https://news.climate.columbia.edu/2022/09/20/you-asked-dinos... We're going to need to adapt, and things will be harder, but I believe it's totally doable.

OK, so this is fine? (No, I do not believe that)

  Pretty much yes

    Vanuatu might disagree. In Vanuatu, sea level rise is a very real concept with a number of communities already being inundated during high tides (2016) ref: https://www.spatialsource.com.au/sea-level-rise-mapping-reaches-vanuatu/ https://www.spatialsource.com.au/sea-level-rise-mapping-reac...

      Yeah but we went from “oh no we’re all going to die and we have to prepare our kids for that eventuality” to “oh no Vanuatu is sinking” in just a few HN comments. In that light I’d like to underline that in the “this is fine” meme, things are actually on fire. It’s an apt comparison.

        > Vanuatu is sinking This implies that Vanuatu's absolute elevation is decreasing. I can find no reference for this. If this decrease is true, please supply your sources.

        Pfff come on, it’s a figure of speech.

        Upvoted. You're right. It was clearly written but I misread the tone+content anyway.

  I didn't say that fyi, your statement here does not reflect my feelings. The headline doesn't either, because Earth has been very hot in the past.

When all that carbon was in the atmosphere, dinosaurs weren't even around yet.

  That's not true is it? There was much more CO2 during dinosaur times than today. https://news.climate.columbia.edu/2022/09/20/you-asked-dinosaurs-survived-when-co2-was-extremely-high-why-cant-humans/ https://news.climate.columbia.edu/2022/09/20/you-asked-dinos...

    A lot of the coal we burn today dates back from the carboniferous period, which predates dinosaurs by a lot.

I wouldn't characterize ocean ecosystems dying from the bottom up as "totally doable" but, sure, the resource wars probably won't kill off the entire human species.

  When I say totally doable, I mean humanity surviving is totally doable. I guess I was thinking after the current ecosystems are wiped out, it will open up the niche for something else to take hold and evolve in their place. Isn't that what the geological record shows during mass extinctions?
