             abstract = "In this work we analyse the dependence of global surface air 
                         temperature (anomaly temperature-dT) on solar (sunspot number-Rz) 
                         and geomagnetic activity (aa index) over different time-scales. We 
                         use annual averages in the period 1880-2000 and decompose the data 
                         in frequency levels through the wavelet multi-resolution analysis. 
                         We have observed that the dT series is better correlated with aa 
                         than with Rz in most of the time-scales. We have also noticed that 
                         the 22-year solar activity signal is stronger and more persistent 
                         in dT than the 11-year signal is. The long-term trend curve of dT 
                         has a format different from the Rz and aa long term curves. This 
                         might implies in that solar-geomagnetic activity effects are more 
                         restricted on time-scales until the 22-year cycle. The long term 
                         variations are most likely to be influenced by terrestrial factors 
                         i.e.- antrophogenic changes.",
