High carbon level = high temperature, because carbon rich atmospheres are roughly hanging out at 400 degrees Celsius, and seeing how the planetary pattern of shifting climates that we knew about from animations we made in the early 2000's we know that the extreme weather shifts meant to be happening 20,000 years from now, have begun happening now, and that's the problem

You're not gonna burn up, it's gonna turn into a combination of extreme hurricanes, extreme coldfronts, extreme lightning storms, extreme heat in the summer, and extreme cold in the winter, with rising winds, more damaging hurricanes, and increases of literally all forms of natural disasters

Because this how chemistry works

And the planet is a giant cocktail of gas chemicals just waiting to go ballistic

The storm in texas, in florida, the snow in egypt, the floods and droughts all over the world, the hurricanes in european and american regions, extreme coldfronts, etc

You won't die from suffocating from a lack of oxygen, or not generating enough oxygen for the planetary body to maintain the life within it, you'll die from your power shutting off from a -70 Celsius storm putting thick ice on all your power lines well a hurricane rips your roof off, if you survived the 60 degree Celsius summer of extreme hurricanes, flooding rains

It's just negligent to pretend this isn't just a chemistry fact
