Argue with facts, it’s easy you actually do some fact checking and research. Seriously do your own research not conspiracy stuff just freely available peer reviewed facts, I tell my 4 university educated including phds to do the same frequently and they’re often shocked.Umm it's around 400ppm from memory.
Are you saying volcanoes emit more than humans that's ridiculous, I'm aware co2 concentrations have fluctuated over time and the climate changes over time naturally (that trend actually should be cooling the earth but the opposite is occurring due to human activities).
I'm not going to argue with a climate denier lol.
