We might be in a nuclear winter long before we see this rise in CO2 by the way conflicts are escalating around the globe...^^^
I believe nature has a chain linking everything together in a delicate balance and we will see more of this.
Video posted above, which suggest current CO2 levels at 0.04% only is no big deal. It's around 440 parts per million, so 0.044%
What is not mentioned, is that at 0.5% we start getting migrains when breathing, at 1% drowsiness comes in and at 4% it becomes lethal. No one is sure, but at some point when nature cannot contain it, there will be a runaway effect.
But I do agree that nature is symbiotic with it's balance and we have disrupted that balance in a negative way....
However, we do see evidence of vast changes in both climate and environment from historical data....oceans have risen and fallen for example and global temperatures have varied over the millions of years.
