This image in wikipedia shows that the temperature is going to increase 4.1-4.8 °C in 2100 if no policies are taken.
How much raise in temperature can be reached in later times?
Is there some limitation to temperature increase?
For example, as far as I know, it is considered that the amount of available fossil fuels in the Earth is limited. What will happen if humans burn all the resources they can find to produce more CO2?
What is the maximum damage level, the maximum warming that can be reached by the oxidation of carbon by humans?
To extrapolate the graph, the upper border of the pink red area is going to be like 9 °C in 2200, and bottom border is going to be like 1 °C. It gets its peak in 2080 and then goes down.
So, can I ask some questions about this, if you agree with this prediction?
About the upper border: how far up can it go? Can it go to values like 20, 50, 100, 200 °C?
About the bottom border: why does it go down? I guess because plants and algae (may) start to grow better (because of the warm climate and abundance of CO2 and they suck in all the CO2.
