Droughts and Global El Nino Events

The University of Montana has been researching global climate change. The research shows that there have been widespread increases in plant growth and evaporation due to recent global climate trends.  El Nino is a disruption of the ocean-atmosphere system in the tropical Pacific with important consequences for weather around the globe. The rise in evapotranspiration (the process by which water is transferred from the land to the atmosphere by evaporation from plants and soil) is increasing the risk of droughts with rising temperature trends, especially during periodic drought cycles that have been linked with strong El Nino events. The researchers have a long-term global satellite record of land evapotranspiration and use remote sensing satellite data. They predict that if these trends continue, it will likely exacerbate regional drought-induced disturbances, and even intensify it during dry climate phases associated with El Nino events.
Droughts are caused by a decreased amount of precipitation. This extreme lack of rain will cause regions around the world to slowly dry out. There are three different forms of droughts; Meteorological, Agricultural, and Hydrological. Meteorological Droughts refer to the degree of dryness. Agricultural refers to agricultural impacts. Throughout the duration of droughts, the weather is usually extremely hot. Droughts cause many complications varying upon deaths and economic issues.
