I don't have any reason to think it's an AI-generated video or a fabrication of any type. Dr. Moore has been outspoken on this subject for a good while now; nothing he says here contradicts his well-known stance of the past X number of years, and it's certainly not wrong: CO2 is what plants breathe IN; it's where the CARBON in wood comes from (not from the ground -- from the freakin' AIR), and increasing the (very small) carbon dioxide levels in the air a bit will only make for a greener and more lush world (think of the Jurassic era, for instance) help farmers grow food.
