Climate changed when the wooly mamoths became extinct too. I don't think people are disputing that climates change. What is disputed is the cause.
volcanic ash and possibly the effects of a meteor.
Same holds true if you darken the skies with carbon, you get climate change.
the naysayers are bought and paid for.
They usually vote conservative or republican and loathe helping others.
They are the lowest common denominator and their lack of intellect and the void in their minds are filled with rubbish propaganda.
