People had fire in those times but it's extremely unlikely they produced enough CO2 to have an anthropogenic impact on the climate leading to large-scale temper

People had fire in those times but it's extremely unlikely they produced enough CO2 to have an anthropogenic impact on the climate leading to large-scale temperature changes.
I'm not sure what your perspective on this situation is but I think the case for modern anthropogenic climate change with deleterious effects is based on a wide range of different evidence, and a careful accumulation of facts and analysis. Simply pointing out that humans had fire 2Mya doesn't change the general conclusion about today.
- londons_explore 3y agoI suspect gr main change caused by humans >100 k years ago will be wiping out various species and starting fires in seasons and places where fires wouldn't normally start (eg. In places without dry lightning or volcanoes - the only two other ways fires naturally start)
