El Niño is associated with an increased chance of drier conditions and La Niña is associated with an increased chance of wetter conditions. … These adverse impacts may be mitigated through using seasonal climate forecasts.

How does El Nino affect the environment?

In general, El Nino causes global temperatures to rise. … Thusly, on a global scale, El Nino has been shown to lead to fires or flooding due to these unusually extreme conditions.

What is El Niño effect?

El Niño is a phenomenon that occurs when unusually warm ocean water piles up along the equatorial west coast of South America. When this phenomenon develops, it affects weather patterns around the globe, including the winter weather along the west coast of North America.

How does La Niña affect the climate of the Pacific Ocean?

La Niña causes water in the eastern Pacific to be colder than usual. In the same region, El Niño can cause the water to be warmer than usual. Areas that are hit with drought during La Niña years are pummeled with rain in El Niño years.
