Now I don't agree with attitude of person above but we had ice ages

• NineStarPoint 3y ago
  Consider how slowly we were coming out of the last ice age before fossil fuels sped things up. The best geological evidence we have of previous rapid changes are extinction events. As others have said it’s not the change itself but the rate of change that is concerning.

  The ice age transitions were over a much longer period of time. And of course had very transformative effects on the landscape.

  The onset of ice ages is relatively slow - the last ice age took about 10,000 years from its onset to reach the peak of of the ice sheets, and another 10,000 years or so for the ice age to end. At the glacial maximum average global temperatures were about 6°C colder than today, and we've managed to raise temperatures by 1°C in only 100 years. Changes at the speed of man-made global warming (or faster) do happen, but they are uncommon and tend to be associated with catastrophic events and mass extinctions.

    Syre but it also caused many extinction events, yet biosphere survived just fine.

      And that somehow means it's good to start the next extinction?
