An interesting window on how people justified changes in climatic conditions when there was no much talk about CO2:
From page 111 (155 of 790 in the Hitler Table Talks file):
We owe the present fertility of our soil to the deforestation of Italy. If it weren’t for that, the warm winds of the South would not reach as far as here. Two thousand years ago Italy was still wooded, and one can imagine how our untilled countries must have looked.
Well, that is a description of Anthropogenic Climate Change: only, of a different sort.
Given Mussolini’s ideas on planting million of trees to cool down and strengthen up the Italians, one wonders if anybody was getting worried about an upcoming climate war, already at the time…
