"Not all theories or early results are verified by later analysis.
In the mid-1970s, several articles about possible global cooling
appeared in the popular press, primarily motivated by analyses
indicating that Northern Hemisphere (NH) temperatures had
decreased during the previous three decades (e.g., Gwynne,
1975). In the peer-reviewed literature, a paper by Bryson
and Dittberner (1976) reported that increases in carbon
dioxide (CO2) should be associated with a decrease in global
temperatures. When challenged by Woronko (1977), Bryson and
Dittberner (1977) explained that the cooling projected by their
model was due to aerosols (small particles in the atmosphere)
produced by the same combustion that caused the increase in
CO2. However, because aerosols remain in the atmosphere only
a short time compared to CO2, the results were not applicable
for long-term climate change projections. This example of a
prediction of global cooling is a classic illustration of the self-
correcting
nature of Earth science. The scientists involved were
reputable researchers who followed the accepted paradigm of
publishing in scientific journals, submitting their methods and
results to the scrutiny of their peers (although the peer-review
did not catch this problem), and responding to legitimate
criticism."
