- Abstract
- Human activities including fossil fuel burning are currently altering the global
climate system at rates faster than ever recorded in geologic time. Biomass burning causes
carbon dioxide emissions equal to 50% of those from fossil-fuel combustion and so are
highly likely to influence future climate change. However, aerosols continue to be one of
the least understood aspects of the modern climate system and even less is known about
their past influence. Ice and lake core proxy records provide quantifiable data on past fire
regimes across most spatial and temporal scales. Some monosaccharide anhydrides such
as levoglucosan, mannosan and galactosan are used as specific molecular markers for
biomass burning as they can only be produced by combustion processes at temperatures
greater than 300
o
C and are present in both ice and lake cores. Other paleofire tracers such
as microcharcoal, polycyclic aromatic hydrocarbons, and pollen records augment the fire
history derived at single sites or across regions. As both pyrochemical and climate para-
meters are determined from the same depth and time within the ice or sediment matrix,
the multi-proxy nature of ice and lake cores presents an ideal material to investigate the
links between fires and climate change. (literal)
