Harvard University experts have recorded a sharp decrease in the frequency of forest fires.
In their opinion, this is due to the abandonment of practice.slash-and-burn agriculture, when forests were burned in order to use the vacated land for planting crops.
Later, with the development of progress, by the middle of the 18th century, most European countries abandoned this practice: this led to a sharp decrease in the frequency of forest fires.
It is traditionally believed that the frequency of forest fireswas much lower in the pre-industrial era than it is today. Our analysis of ice deposits in Antarctica shows that in the recent past they occurred much more often than today.

Based on the results of the work, the authors stated thatClimatologists underestimate the extent to which natural and man-made fires affected the Earth's climate in the pre-industrial era. This may explain why current climate models overestimate how much fluctuations in greenhouse gas concentrations affect Earth's surface temperatures.
