It needs to be expanded to account for the vertical and regional structure of radiative forcing and also for
nonradiative climate forcings.
Not exact matches
Other
nonradiative forcings modify the biological components of the
climate system by changing the fluxes of trace gases and heat between vegetation, soils, and the atmosphere and by modifying the amount and types of vegetation.
However, this approach may not convey appropriately the impacts of
nonradiative forcings on societally relevant
climate variables such as precipitation or ecosystem function.
These
nonradiative forcings generally have radiative impacts, but describing them only in terms of this radiative impact does not convey fully their influence on
climate variables of societal relevance.
Some forcings affect the
climate system in
nonradiative ways, in particular by modifying the hydrological cycle or vegetation dynamics.
Nonradiative forcings generally have significant regional variation, making it important that any new metrics be able to characterize the regional structure in forcing and
climate response — whether the response occurs in the region, in a distant region through teleconnections, or globally.
As is the case for regional radiative forcing, further work is needed to quantify links between regional
nonradiative forcing and
climate response.
Several
nonradiative forcings involve the biological components of the
climate system.
Does not fully characterize the
climate impact of
nonradiative forcing, the indirect aerosol effect (other than the first), and the semidirect aerosol effect
Further work is needed to quantify links of regional
nonradiative forcing to regional and global
climate response
Indeed, because
nonradiative forcings affect multiple
climate variables, there is no single metric that can be applied to characterize all
nonradiative forcings (Marland et al., 2003; Kabat et al., 2004).
Finally, we examine ways to improve the application of radiative and
nonradiative forcing metrics in policy analyses directed at
climate change.
