There is a growing literature on the potential for stratospheric influences on climate (e.g. Matthes et al 2006, Gray et al 2010, Lockwood et al 2010, Scaife et al 2012) due to warming of stratospheric ozone by solar UV emissions. (watertechbyrie.com)
It may not be the most important factor in GW, but there are impacts for ozone, strat - trop exchange, and hypotheses concerning stratospheric influence on atmospheric dynamics. (realclimate.org)
This «lifting the lid» of climate models is expected to improve our understanding of solar - induced stratospheric influences on the troposphere. (climateaudit.org)
