Best website to understand is NASA data. Many of “speculators” ideas are debunked with facts.

For me it’s not anymore about if its real or who did it (this was 1960 mentality, not 2024) but more about how can we implement solutions without main/average people going crazy because they can’t produce CO2 or methane like they are used to. We live in a limited earth with limited ressources but we have the room for unlimited useful and fun solutions.
