Atmospheric sciences Atmospheric sciences Atmospheric sciences are the study of the Earth's atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes (both long and short-term) that define average climates and their change over time, due to both natural and anthropogenic climate variability. Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important. Atmospheric science has been extended to the field of planetary
Effects of long-term benzodiazepine use of the literature on use of benzodiazepine and nonbenzodiazepine hypnotics concluded that more research is needed to evaluate the long-term effects of hypnotic drugs. The majority of the problems of benzodiazepines are related to their long-term use rather than their short-term use. There is growing evidence of the harm of long-term use of benzodiazepines, especially at higher doses. In 2007, the Department of Health recommended that individuals on long-term benzodiazepines be monitored at least every 3 months and also recommended against long-term substitution therapy in benzodiazepine drug misusers due to a lack of evidence base for effectiveness and due to
