Incidentally that fact *** misses off Hogboms contribution. ISTR He
was the first to estimate the industrial CO2 contribution to the
atmosphere as 0.1% in 1896 (hence he reckonned about 1000 years at that
rate to double the concentration)
I can't find a trustworthy primary source for this recollection online.
Yes, and if you dig into the historical records you'll find ~ 350 ppm of CO2 in
the atmosphere recorded in parts of Europe in the 1800s.
Generally downwind of coal burning cities and heavy industry.

Well, I recall one instance in Britain's Lake District which hardly falls into that
category.

What was the historical carbon burn rate? Medieval Europe chopped down
and burned their trees, plus loads of coal. Sounds like a question
for Super Don (Klipstein). ;-)

There weren't as many of them, but they were tremendously energy
inefficient. Third worlders' lighting today is like <1% efficient,
and lighting accounts for 1/3rd of U.S. electrical usage.

What was the carbon pulse to the atmosphere like
back then?, and maybe they saved us from universal ice?
