| Session Description | Increases in CO2 and other greenhouse gas concentrations are unequivocally known to cause the past, present, and future climate warming. However, some studies suggest that the climate effects of short-lived climate pollutants (SLCPs) such as BC, tropospheric ozone, methane, and pollution aerosols could be as large as that of long-lived greenhouse gases. Reduction of SLCPs might be an effective way to lessen global warming due to CO2. Contrast to long-lived greenhouse gases, the distribution of SLCPs is not uniform globally because of their relatively short lifetimes in the atmosphere. Hence, their climate effects are more important for source regions than the globe, and they are highly uncertain yet. Although the direct climate effect of SLCPs could be largely focused on regions at first hand, the atmospheric responses could be broadly global through atmospheric teleconnection and other complex natural variability. In this session, we invite studies on sources, atmospheric transport, and chemical formation of SLCPs to quantify their effects on air quality as well as studies focusing on climate effects of SLCPs on global and regional climate changes, and on natural climate variability using either observations or modeling or both. |
