From page 1...
... Human activity has contributed to increased atmospheric concentrations of CO2, CH4, and CFCs. The increased atmospheric concentrations of greenhouse gases may increase average global temperatures.
From page 2...
... This temperature rise could be attributable to greenhouse warming or to natural climate variability; with today's limited understanding of the underlying phenomena, neither can be ruled out. Increases in atmospheric greenhouse gas concentrations probably will be followed by increases in average atmospheric temperature.
