SUMMARY:How does atmospheric chemistry affect your climate modelling resul
 ts? - Peer Johannes Nowack\, University of Cambridge

CONTACT:Dr. Pranab Deb
DESCRIPTION:This talk will give a broad overview of how stratospheric comp
 osition changes\, under increasing atmospheric greenhouse gas concentratio
 ns\, can affect the large-scale climatology found in state-of-the-art clim
 ate models. The aim of this talk is not to delve deeply into the chemical 
 mechanisms behind these effects\, but rather to explain what it means in g
 eneral for climate model results. Two topics will be discussed in detail. 
 I will review\, firstly\, the recent discussion on the effect of tropical 
 upper tropospheric and lower stratospheric ozone changes on global warming
  projections (see e.g. Nowack et al.\, A large ozone-circulation feedback 
 and its implications for global warming assessments\, Nature Climate Chang
 e 2015) and\, secondly\, the effect of ozone changes in solar geoengineeri
 ng schemes.
