Low intensity forest and grassland fires create airborne particulates and charcoal which act as environmental cleansing agents. The morphological integrity of plant material which remains after burning creates a natural filter with varied porosity.

In this paper we briefly review current knowledge concerning the possible consequences of a changing climate for terrestrial ecosystems. Forests and grasslands of western North America figure prominently in the discussion, but our intent is to consider general principles rather…

Airborne measurements of 13 trace gases from seven forest fires in North America are used to determine their average emission factors. The emission factors are then used to estimate the contributions of biomass ubrning to the worldwide fluxes of these gases. The estimate for NH3…

A record of prehistoric and historic burning of carbonaceous materials may be found in the elemental carbon contents of the sedimentary columns. The widespread dissemination of such carbon as microcrystalline graphite is indicated by its presence in atmospheric dusts collected…
