This only means 4 degrees cooler is bad. In itself it says nothing about 4 degrees warmer.

- DennisP 5y agoDeeper in geological history we can see what happened at 4 degrees warmer. The result was mass extinction and much less life on the planet, mostly clustered around the poles. Equatorial regions were uninhabitable. Sea levels were quite a bit higher.
- jules-jules 5y agoDo you have a paper / article with more details?
- DennisP 5y agoA good place to start is the book Six Degrees by Mark Lynas, which has references to hundreds of papers. Also Hansen's book Storms of My Grandchildren has several chapters on the geological history.
- jules-jules 5y agoThanks, appreciate it.
- akvadrako 5y agoNo. Earth for the past 2 million years has been in an ice age, several degrees cooler than the hundreds of millions of years before, when there was plenty of life thriving.
- radu_floricica 5y agoI'd like to look it up, if you give me something more specific than that.
- wazoox 5y agoBasic climate denialism. See: https://youtu.be/1BDmIis9STE?t=464 https://youtu.be/1BDmIis9STE?t=464 quote: "1.5°C is a disastrous world, no question. 2°C is an impossible world". I have nothing more to reply to your complacent stupidity but that you're dangerously ignorant and denying basic science because it's inconvenient to your beliefs. It's pretty sobering to see this toxic mindset so common in the techno-optimist crowd of HN. But this is nothing else than wishful thinking -- the science data is absolutely overwhelming.
- johnchristopher 5y agoHum. Yes. It says a 4 degree difference is mucho significant. What we see today is already bad, no reasons more is going to get better.
