Scientists and the general public alike encounter scientific terms such as climate change, global warming, greenhouse effect, and carbon dioxide a few times every day in newspapers, radio broadcasts, and television news, as well as in conversation. This is perhaps the first time in the history of science that a scientific issue has gotten so much attention from the public. As a scientist, I am pleased about the public's interest in science. Unfortunately, I have found that this great interest in climatology is largely the result of a proliferation of confusing stories in the media that are based on misinterpreted information about the greenhouse effect of carbon dioxide. Many people bring up several misunderstood issues when I discuss the present warming trend. Even some policy makers and government officials seem to be confused.
