      Has there ever been a period in Earth’s history where CO2 concentration in the atmosphere changed this quickly without being accompanied by mass extinctions?

        Boy, got awful quiet all of a sudden, huh? 🤣😂 Bro is over there desperately trying to convince himself that nah, he could totally live on Venus as long as he only measures the surface temperature as an average over 40 billion years, give or take

      Humans came into existence during the ice caps phase.

      The earth may have seen higher temperatures but we as a species or any of our humanoid ancestors have certainly not.

      It’s disingenuous to frame the issue as just another hot period on earth

      I think the point isn’t so much that Earth will heat up but that it will do so at a tremendous pace (in geological timescales). Nature can’t adapt so quickly. Basically it will lead to a mass extinction simply because of how quickly it is happening. Nature takes a longer time to genetically adapt to a changing environment than humans have even existed. That’s the problem.

      Take the rate of change by time of that curve and plot it, you’ll see a massive spike during today, And a line that bounces around zero for the rest of timeframe.
