Valsavarenche, Valle d'Aosta (Italy), 20-28 June, 2012
The XX edition of the Alpine Summer School has been dedicated to presenting the current state-of-knowledge concerning the effect of short-lived species, in particular light absorbing aerosols, on climate with an emphasis on our current state of knowledge as well as future mitigation strategies. The course discussed the specific links between short-lived species in particular aerosol and their absorbing components and the cryosphere dynamics, with a focus on regions of the world that are facing dramatic changes including South-Asia, the Hindu-Kush-Karakorum-Himalaya, and the Arctic. These regions are important examples where efficacies of the radiative forcing from short-lived species and particularly aerosols are expected to have a significant impact.
