GC: n CT: The massive amount of processing power generated by computer manufacturers has not yet been able to quench our thirst for speed and computing capacity. In 1947, American computer engineer Howard Aiken said that just six electronic digital computers would satisfy the computing needs of the United States.
CG: n CT: Stratospheric ozone protects the earth’s surface from damaging short-wave ultraviolet (UV) radiation. Ozone is produced in the upper stratosphere by short-wave sunlight, which together with chemical reactions dissociates the ozone again to create a dynamic balance between production and loss. Anthropogenic emissions of inert compounds containing chlorine
GC: n CT: Tropospheric ozone is also recognised to be a threat to human health (WHO, 2003; Lim et al., 2012) and have a deleterious impact on vegetation (Fowler et al., 2009), and through plant damage it impedes the uptake of carbon into the biosphere (Sitch et al., 2007) as
