Great, so catastrophic predictions are uncertain and how long will global warming continue is uncertain. Hopefully it will be high enough to prevent Ice Age.
Your own sources tell us that their predictions are UNCERTAIN, and yet you believe that they are certain about future level of global warming?!!!
There is not a single thing in science that does not contain undertainty. The beautiful thing about science is that uncertainty gets quantified. The uncertainty here is that, assuming we continue spouting CO2 into the atmosphere unchecked, the future will either be very difficult or we will simply go extinct. The reason I included that link was to show that predictions are not for the Earth to suddenly explode, but that the difficulties can be studied, quantified, and through mitigation and adaptation we can live through this. If we do nothing, we might have to get really, really good at fasting.
What prevents temperature from going above average of 23C or so? Earth's climate averaged 23C degree for millions of years. This seems to be its more usual temperature. The current 14.51C temperature is unusual.
What prevents interglacial that we live in from turning back into ice age? The fact that temperature is rising is the whole meaning of current Holocene interglacial which started about 11,400 years ago.
Considering that IPCC themselves stated that "The future level of global warming is uncertain" (which is claimed to cause severe weather) you seem to be certain that it is either going to be very difficult or we go extinct? What if the temperature stalls at current levels for long period of time? What if it even goes slightly down. After all, IPCC themselves are uncertain about future level of global warming and we are in interglacial.
I believe that severe weather occurred as long as climate existed. Hot temperature has its downsides, and cold temperature has its own.
As for humans going extinct, there are other possibilities such as asteroid strike (which could have killed the dinosaurs).
