The basic components of the greenhouse effect may be identified, although questions remain about how many greenhouse gases contribute to global warming, and how significant each is to the total phenomenon. Scientists also disagree about how quickly the effect will occur, and how important it will prove to be compared to natural mechanisms. Wide disagreement over two complex subjects, the possible interaction of the oceans and how changes in cloud cover may influence warming, has led to predictions ranging from little change to complete climatic disruption. The disagreement is also fueled by the computer models that climatologists use to understand global warming. Some global models have simulated actual conditions, leading climatologists to conclude that their historical data are useful for predicting the future, but it is doubtful that any simulation can include all the necessary variables. Many models lack regional details, and very few data are included about the atmosphere's interactions with the oceans, which comprise three-quarters of the earth's surface. 7 refs.
