	The Regional Impacts of Climate Change
		Many of the ecological impacts on freshwater systems depend on hydrological responses to climatic change, which are relatively uncertain given the current status of GCMs.
		The problem is one of scale: Many of the most significant impacts on freshwater ecosytems will result from hydrological changes at the scales of small catchments and drainage basins (which are unresolved by GCMs) and changes in hydrological variability rather than mean conditions, which is poorly taken into account by climate models.
		It is likely that the impacts of climate change will be more pronounced in the littoral zones of lakes than in the pelagic zones.

		A Zambian man uses fire to clear away dead grass.
		By understanding why people burn the way they do, we can develop effective fire management and education programs, and garner support among local communities for ecologically-friendly fire use.
