When I was born in 1945, the first air I breathed contained about 310ppm CO₂, about 10% above what it had been through all of human & probably our prehuman primate ancestors' history, millions of years.
Now it has recently peaked for this year at 424.38, 2ppm higher than last year's peak & 36% higher than when I was born & about 51% above the baseline.
For anyone who might point out that these are very small numbers, Hydrogen Cyanide is lethal not much over 100ppm, & as far as % increases go, if oxygen had increased by the same 50% then it would be a very different world, we would all he living way up in the mountains where the reduced Oxygen level was less toxic watching the smoke from everything below us burning.
Just an old fart's perspective.
