To introduce myself:
I am an engineer in energy systems and currently work as a software developer.
I can tell you a lot about the global energy system, if you ask me and I will frankly try to get people to understand the issues around this a bit better.
To make a short bet:
“It is not clear if we can extract that much fossil fuels that global temperature will rise above 4.5 °C”
… well predictions are difficult…
