An EETD Seminar on January 12, 2011 -- by Pablo Campra, University of Almeria, Spain
In recent years, there is a growing interest in the design of geo-engineering strategies to offset warming exerted by greenhouse gases through radiative rebalancing of the Earth´s energy budget. The increase of land cover albedo or reflectivity appears as one of the few feasible geo-engineering options. In the case of farmland, greenhouse farming has empirically shown to be effective in warming offset, with a net cooling effect shown in the long term climatic data: this is the case of our recent study on the impact of changes in albedo on the surface air temperatures trends at the biggest concentration of greenhouses in the world - the province of Almeria, in southeast Spain.
