Surface warming by the solar cycle as revealed by the composite mean difference projection
Abstract
By projecting surface temperature data (1959-2004) onto the spatial structure obtained objectively from the composite mean difference between solar max and solar min years, we obtain a global warming signal of almost 0.2°K attributable to the 11-year solar cycle. The statistical significance of such a globally coherent solar response at the surface is established for the first time.
