Dr. Fairbanks will also, separately, present a refined model of continental deglaciation, with an accurate new methodology for predicting changes in sea level as a result of changes in land ice volume.
ORIGINS OF ARCTIC SOOT
The fragile Arctic is especially susceptible to the impacts of particles and other pollution. Soot, transported to the Arctic from Asia, Europe, and elsewhere, may affect the radiative balance there, shifting temperature profiles, clouds and precipitation. Absorbing particles, such as black carbon or soot, may accelerate ice and snow melting. Dorothy Koch and James Hansen discuss what global climate models reveal about the origins of black carbon, in the Arctic. Model results suggest a larger contribution of soot and other particles from South Asia to the Arctic than has been inferred in previous Arctic haze studies. hDorothy Koch, Associate Research Scientist, GISS at Columbia, 212-678-5605, DKoch@GISS.nasa.gov; James Hansen, Director, GISS at Columbia, 212-678-5500, JHansen@GISS.nasa.gov.
