    Yeah it’s great because it’s a very small slice of earths history. It shows how dramatic the affect we humans have had on earths climate has been.

    Earths climate has done crazy things.

    See history of the world on YouTube. The stuff earth has been through is crazy.

    But the key is how long it takes for something so dramatic to happen to earth. The great dying, snowball earth, etc etc all takes hundreds of thousands of years. Not hundreds of years.

    And we can see in the geologic record how fucking extreme the consequences were for life on earth in those events. Extrapolating to what we are doing here, it could be an extinction event. We won’t know it because it’ll still be thousands of years for that irreversible process to happen.

    Look at this xkcd that’s much less arbitrary about it’s time scale

    In short, the time scale they are showing this graph on is generous if anything.
