much, much less. Simply because there were less people. I am pretty sure 
that if you keep the population at historical levels of a few million 
you can reach an equilibrium.

yes to cook mostly and in the colder regions to keep warm in the winter. 
Burning of fuel was less efficient and I don't know if that compensates 
for increased mobility and use of electricity around the house. My guess 
would be that an average US citizen does burn more carbon than, say, the 
average San or Inuit. I might be brainwashed by extreme left wing 
journalists though.
