Answer

Answer:

B. Steady surface temperature increases were noted between the 1970's and 90's.

Brief Explanations:

In the 1970s - 90s, observed surface - temperature rises led to a shift from global - cooling to global - warming concerns. Other options are incorrect as the science community doesn't aim to frighten, air pollution was a concern before the 1980s, and ocean acidification isn't related to the shift in temperature concerns.
