Solar cycle length, greenhouse forcing and global climate
Article Abstract:
A new climatic model based on data from 1765 to 1985 showed that variations in the solar cycle contributed to the rise in global temperatures during that period but not enough to oust human-produced greenhouse gases as the dominant cause. The upwelling-diffusion energy-balance model compared the likely climatic effects of the solar cycle and the greenhouse gases both by themselves and together. Global warming was found to result chiefly from the gases' rising concentrations rather than from variations in solar activity.

Implications for global warming of intercycle solar irradiance variations
Article Abstract:
A climate-ocean model based on data since 1856 shows that changes in the amount of solar radiation reaching the Earth helped to raise global temperatures since that time but that the increase in greenhouse gases (GHGs) was the more important factor. The model compared data on GHG levels, recurring fluctuations in solar irradiance and atmospheric temperature. The impressive but circumstantial evidence for the Sun's role in global warming must be taken into account when considering the effects of GHG concentrations.

Variations in solar luminosity and their effect on the Earth's climate
Article Abstract:
Several advances in the study of variations in total solar irradiance (TSI) itself, which affect the planet's energy balance directly is reviewed. This driving is relatively straightforward compared to possible climate driving due to the variable solar output of ultraviolet light, and of magnetized plasmas in the solar wind.
