Lead pollution in the air may have considerably curbed the greenhouse effect in the past. Lead pollution in the air stimulates the formation of ice particles in clouds. Scientist have found that particles containing lead are excellent seeds for the formation of ice crystals in clouds. This not only has a bearing on the formation of rain and other forms of precipitation but may also have an influence on the global climate.
