For thousands of years, indigenous Australians modified the landscape of the continent through regular and widespread burning of vegetation. Their use of fire was in part for hunting purposes and also for clearing pathways, for signalling other tribal groups and for promoting grass regrowth. Results from a recent climate modelling experiment suggest that these traditional burning practices may have been of sufficient magnitude to change the climate of northern Australia.
