hey look at this, primate life on this planet has thrived in historical environments with co2 levels over 1000ppm

none at all, unfortunately the planet's ability to support carbon-based life only increases until atmospheric co2 gets to be in the 2000ppm range. thats centuries away if it happens at all. if you think earth is too crowed now, you're going to hate the future. the population of africa has already been doubling every 25 years for the past century, by the time you're old this planet will be teeming with africans, they'll be 20 billion of the 30 billion or so people on the planet

NOOOOOOOOO YOU CAN'T JUST QUESTION GLOBAL WARMARINOOOO NOOOOOOOOOO
YOU MUST BELIEVE THE WORLD IS ENDING SO YOU'LL DO WHAT WE SAY, GIVE UP YOUR RIGHTS TO GO OUTSIDE AND SIT INSIDE YOUR WAGIE CAGIE WHILE WE TAX YOU AT 50% TO SAVE THE WORLD THAT YOU CAN'T ENJOY ANYMORE
DO WHAT WE SAY AND NOT WHAT WE DO PEASANT

even if it is real, the history of life on earth suggests that atmospheric co2 can be at least 400% greater than it is today without any noticeable negative impact on humanity, however there isn't enough carbon stored in fossil fuels on earth available for it to go that level, co2 from fossil fuel sources will run out two or three centuries before a 400% could be seen

>CO2 in the atmosphere is increasing.
And that's a good thing.

Literally all life on the planet almost ended because most CO2 was trapped in fossils underground and during ice ages even more was trapped in the ice. Plant life needs a minimum of about 150ppm and we came dangerously close to that threshold.
Plant life thrives on much higher levels of CO2 up to about 2000ppm after plants are negatively affected.
Humans can survive up 60000ppm.
During the Cambrian-Ordovician period CO2 was at between 4000 and 6000ppm and yet that was when the first coral reef formations took place. A far cry from the bleaching that's supposedly being caused at 400ppm.

Heres the history of atmospheric CO2 concentrations on this planet according to the same scientists who supposedly say that increased CO2 levels are going to mean the end of life on Earth. zOMG would you look at that!?!? CO2 level have been much, much higher in the past as life on Earth was just fine. Primates thrived 35-40 million years ago in an atmosphere that had more than twice as much CO2 was what we've got now.
