Is there evidence that fires are unusually more frequent than they were before ? When I visited California a couple of years back we saw exhibitions about the forest parks which included histories and memorials to fire fighters from the 1920s and 1930s to the present day.
In this evidence of course you would have to factor out the encroaching nature of cities, tourism and leisure - all those intrepid wilderness types camping out deeper and deeper into the forests in increasing numbers.
