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 months of use. Many of these adverse effects of long-term use of benzodiazepines begin to show improvements three to six months after withdrawal. Other concerns about the effects of long-term benzodiazepine use, in some, include dose escalation, benzodiazepine abuse, tolerance and benzodiazepine dependence and benzodiazepine withdrawal problems. Both physiological tolerance and dependence can lead to a worsening of the adverse effects of benzodiazepines. Increased risk of death has been associated with long-term use of benzodiazepines in several studies; however, other studies have not found increased mortality. Due to conflicting findings in studies regarding benzodiazepines and increased risks of death including
