Even though Africa contributes least to global warming, it is the inhabited continent that is affected most, says a new study by the British Hadley Center. Scientists at the Hadley Center think this is happening because more industrialized continents, such as North America and Europe, produce more carbon dioxide than Africa does. These pollutants, it seems, heighten the greenhouse effect but provide some localized protection from the global warming it causes. A minority of scientists say that the overall rise in the earth's temperature is not caused by manmade pollution and the greenhouse effect, but is caused instead by natural factors such as increased energy from the sun or volcanic activity.
