| Zusammenfassung |
| Several short-lived pollutants known to impact Arctic climate may be
contributing to the accelerated rates of warming observed in this region
relative to the global annually averaged temperature increase. Here, we
present a summary of the short-lived pollutants that impact Arctic climate
including methane, tropospheric ozone, and tropospheric aerosols. For each
pollutant, we provide a description of the major sources and the mechanism
of forcing. We also provide the first seasonally averaged forcing and
corresponding temperature response estimates focused specifically on the
Arctic. The calculations indicate that the forcings due to black carbon,
methane, and tropospheric ozone lead to a positive surface temperature
response indicating the need to reduce emissions of these species within and
outside the Arctic. Additional aerosol species may also lead to surface
warming if the aerosol is coincident with thin, low lying clouds. We suggest
strategies for reducing the warming based on current knowledge and discuss
directions for future research to address the large remaining uncertainties. |
