The terrestrial biosphere sequesters up to a third of annual anthropogenic carbon dioxide emissions, offsetting a substantial portion of greenhouse gas forcing of the climate system. Although a number of factors are responsible for this terrestrial carbon sink, atmospheric nitrogen deposition contributes by enhancing tree productivity and promoting carbon storage...
Summer streamflows in the Pacific Northwest are
largely derived from melting snow and groundwater discharge.
As the climate warms, diminishing snowpack and
earlier snowmelt will cause reductions in summer streamflow.
Most regional-scale assessments of climate change impacts
on streamflow use downscaled temperature and precipitation
projections from general circulation models (GCMs)...
