Playing with fire when we talk about tipping points and runaway climate change.-djtexas

This means we have to be careful to not get burned, and stay aware of that, then it shouldn’t be a problem to handle fire.

So as I gathered from your intel (thanks for that) the awaited worst case by 2100 would be avarage temperature increase of 5°C. Would mean:

[“Hot-house Earth” incompatible with human civilization, most of the planet becomes uninhabitable, population reduction to one billion] – https://blog.datawrapper.de/climate-crisis-global-warming/

[The Sixth Mass Extinction, during the last 450 million years there were five before, each destroying 70-95% of previously existing life.] – https://earth.org/sixth-mass-extinction-of-wildlife-accelerating/

This considered; this sixth Mass Extinction mainly caused by climate change will not wipe out all life on earth. (With all I mean every last bit of self replicating Amino and Nucleic Acid anywhere on the Planet) “Life is very resilient.“-morgankane01

Mankind on the other hand will have a rough time, without adaption an expectet decrease of suitable habitat leading to population decrease. Which is perhaps severe enough to cause human extinction later in the end. But I think mankind could survive even this worst case in small numbers though enough to avoid extinction. Of course civilisation and lifestile as we know it to day would crumble and change.

I have some trust in the adaptability of humans. To adapt and with that reducing the impact of such a crisis and survive the ods. Let’s not forget the speed of adaptation that the human mind is capable of, instead of having to breed through generations of accidental mutations one thought can lead to change of behaviour and enviroment. Geologicaly and evolutionary speaking its an instant. Like we are seeing with this human made climate change. This speed and the physiological capabilities were what gave mankind the edge in evolution and caused such a thriving in the first place.

Bottom line, yeah it seems human extinction caused by climate change is possible, and in order to enshure its continuing survival past the 22th Century mankind should do something about it. Unless of course humans want to take the risk of extinction.
