Is the slow and gradual increase in CO2 we’ve experienced a positive or negative for humanity?
"slow and gradual"?
It’s only otherwise if you believe liars such as Michael Mann and Al Gore.
More yesses than no’s but no one wants to defend a yes.
Based on the trees, quite positive. They love that stuff.
CO2 is plant food. It is only 400ppm now whereas optimal plant growth starts at 1,000ppm. It was 2,500ppm during earths greenest time the Jurassic Period. More plant food is good!
Neither since it never has nor never will control climate.
There’s a reason greenhouses use CO2 generators.
