From page 16...
... THE OCCURRENCE OF CLIMATE CHANGE A diverse array of evidence points to a warming of global surface air temperatures. Instrumental records from land stations and ships indicate that global mean surface air temperature warmed by about 0.4-0.8C (0.7-1.5F)
From page 17...
... THE EFFECT OF HUMAN ACTIVITIES Because of the large and still uncertain level of natural variability inherent in the climate record and the uncertainties in the time histories of the various forcing agents (and particularly aerosols) , a causal linkage between the buildup of greenhouse gases in the atmosphere and the observed climate changes during the 20th century cannot be unequivocally established.
