Again arbitrary cutoff at 20000BC.

Lets pick the peak of last ice age and be amazed because since then we are only getting warmer.

Lets also add some exponent predictions in the end, because it worked out so well for Lisa Simpson teeth.

I like xkcd, but this is not their best work.

Sure, whatever. Honestly, I'm tired of arguing with denialists. Really, I do hope that it turns out you're correct and know better than almost every climate scientist on earth.

At this point irrational hope is about the only hope left, so sure. Let's say you're right. Everything is fine. Natural cycles. Whatever.

>I'm tired of arguing with denialists

I don't think that guy is denying anything. He's merely stating that the earth has gone through drastic changes _many_ times in the past.

What makes this change the final one before earth is incapable of sustaining life?

[ForHackernews]

Nobody sensible says Earth will be incapable of sustaining life. Jellyfish, for example, are predicted to flourish in a warming ocean depleted of fish stocks.

I think it still it's an open question whether modern human civilization will survive these changes. Today, people are already dying of heat and rioting for lack of water: https://en.wikipedia.org/wiki/2019_heat_wave_in_India_and_Pa...

If society does collapse from drought, famine, resource wars, etc., then will we be able to rebuild it without all the free energy from fossil fuels, or was that a one-time cheat code? Maybe we're looking at the Great Filter: https://en.wikipedia.org/wiki/Great_Filter

Right now society is monolithic. As individuals we are part of a highly coupled system and we would die without it. What we need are small communities that are independently self sustaining. That will be much more robust and eco friendly I believe

And would literally put us back to the stone age. Even the neolithic had trade networks.

[darepublic]

Don't think you understood my meaning. Trade community and tech are all good things and can coexist with self sustaining communities

Bringing with them tons of changes to the climate, the kind which would kill billions from famines, floods, tornadoes, heat, lack of potable water, etc, in our hugely populated modern world.

>What makes this change the final one before earth is incapable of sustaining life?

We don't merely want an Earth "capable of sustaining life". We want an Earth capable of sustaining us, the whole 8 billions, and not a hellhole of environmental disaster, famine, decertification, and so on.

I could not give less fucks if cockroaches and wolves, e.g. survive, but billions of people are wiped out...

[ghthor]

Some people will survive, and hopefully they figure out what it is that this civilization did wrong and do a better job. This isnt the first time a human civilization has wiped itself out due to spiritual negligence, that is the myth of Atlantis.
