I wonder if the cavemen in the south of England 10,000 years ago knew

Except they wern't, their log fires were not releasing fossil carbon.
Now if they had found some black rocks and also discovered they
burn't well that would be a different matter.

dont be silly. Betwen the end of the ice age and the forestation of
britain, and around 1700, nearly every single tree in the country was
cut down for farming, timber or firewood.

Only coal and iron reduced that to the point we are now more wooded than
at any time in the last 300 years.
