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 was found when compared against those who did not take tranquillisers or sleeping tablets. Most individuals who successfully discontinue hypnotic therapy after a gradual taper and do not take benzodiazepines for 6 months have less severe sleep and anxiety problems, are less distressed and have a general feeling of improved health at 6-month follow-up. The use of benzodiazepines for the treatment of anxiety has been found to lead to a significant increase in healthcare costs due to accidents and other adverse effects associated with the long-term use of benzodiazepines. Long-term benzodiazepine use can lead to a generalised impairment of cognition,
