Answer
Brief Explanations:
The shift from concern over global cooling to global warming was due to observed steady surface - temperature increases between the 1970s and 90s. The science community does not seek to frighten the public. Air pollution was a concern before the 1980s, and ocean acidification is not the reason for the shift in concern about temperature trends.
Answer:
B. Steady surface temperature increases were noted between the 1970's and 90's.
