Estimated solar contribution to the global surface warming using the ACRIM TSI satellite composite

[1] We study, by using a wavelet decomposition methodology, the solar signature on global surface temperature data using the ACRIM total solar irradiance satellite composite by Willson and Mordvinov. These data present a +0.047%/decade trend between minima during solar cycles 21-23 (1980-2002). We estimate that the ACRIM upward trend might have minimally contributed ∼10-30% of the global surface temperature warming over the period 1980-2002.
