You mean the ones that adapted?
Killed animals for food and clothing and burnt stuff to stay warm?
Just have a look around at all the adaptions to your current climate that a high energy society has produced. What produced the roof over your head? The chair you are sitting in? The clothes that you are wearing that were produced half a world away and transported here so you could be kept warm and dry outside, or protected from the Sun.
Correct, but what you are avoiding is balance. There could be a couple of volcanoes that erupt in 2022 and emit more than what we are. But they wont erupt at that level for 200 + years, which is what we do. Industrial revolution is where it all started, but that made NO difference . The coal they burned is insignificant. But from 1980 till now CO2 emissions have doubled. Population and technology. What will 2000 to 2030 do? Same time period. Exponential.
