The results so far show only a correlation between
fires and water cycle indicators, but the data gathered from the study is allowing scientists to improve climate models to be able to establish a more direct relationship between biomass burning and its impacts on drought.

and lengthened
fire seasons.
«On the face of it, elevated CO2 boosting the foliage in dry country is good news
and could assist forestry
and agriculture in such areas; however there will be secondary effects that are likely to influence
water availability, the carbon
cycle,
fire regimes
and biodiversity, for example,» Dr Donohue said.

This leads to different dynamics of the regional
fire cycles: In the Northern US, negative correlations of
fire with
water storage or vegetation for negative lags (
fire leads) suggest that the enhanced
fire frequency will reduce vegetation carbon
and affect subsequent droughts lasting for several years.
