Atmospheric sciences and radiant energy. In contrast to meteorology, which studies short term weather systems lasting up to a few weeks, climatology studies the frequency and trends of those systems. It studies the periodicity of weather events over years to millennia, as well as changes in long-term average weather patterns, in relation to atmospheric conditions. Climatologists, those who practice climatology, study both the nature of climates – local, regional or global – and the natural or human-induced factors that cause climates to change. Climatology considers the past and can help predict future climate change. Phenomena of climatological interest include the atmospheric boundary
Effects of long-term benzodiazepine use for amplifying cognitive decline, although gradual withdrawal is associated with improved cognitive status. A study of alprazolam found that 8 weeks administration of alprazolam resulted in deficits that were detectable after several weeks but not after 3–5 years. Sleep architecture can be adversely affected by benzodiazepine dependence. Possible adverse effects on sleep include induction or worsening of sleep disordered breathing. Like alcohol, benzodiazepines are commonly used to treat insomnia in the short term (both prescribed and self-medicated), but worsen sleep in the long term. Although benzodiazepines can put people to sleep, while asleep, the drugs disrupt sleep architecture: decreasing sleep
