This is the first of a three-part series on common questions about climate change: This first article will address the question of whether the climate really changing.

CFCs, once used commonly in aerosol cans, fire extinguishers, refrigerators, and air conditioners, were responsible for causing depletion of the ozone layer. The paper created such a national stir that ozone depletion is still a
