That’s interesting you say that because I initially had the opposite impression because this would imply that the Earth has experienced major temperature swings much beyond what we’re seeing now and life carried on.

Then I reread and saw the part about increased greenhouse gas effects… I hope those calculations at least are inaccurate.

Its not just about life carrying on though. It wont carry on as usual for humans, and these findings show that we can expect a more rapid and greater increase in temperature than initially expected. This will disrupt food and water supplies, cause inhospitable deserts to grow, and displace a lot of people and animals that were once in tune with their ecosystem before the rapid changes began.

Not to mention we are already halfway to more than doubling pre-industrial atmospheric CO2 levels, the nightmare scenario with 4+ degree warming of the planet seems more likely. These findings mean its going to happen even faster than we thought.
