In 2011, the La Niña climate phenomenon was so strong, which led to a drop in sea level by 5 millimeters. This circumstance contradicts the general trend: with the beginning of the 1990s, the oceans rise by about 3 millimeter per year. It turned out that during the period of strengthening of La Niñi there was a temporary movement of water from the ocean to land. For the indicated period was characterized by an increase in rainfall over Australia, northern South America and Southeast Asia.

The La Niña cycle is the opposite phase of the climate phenomenon El nino. It is characterized by a large-scale decrease in temperature water surface in the center and east of the tropical zone of the Pacific the ocean. During El Nino, the temperature, on the contrary, rises. These fluctuations strongly affect the climate and precipitation patterns throughout the world. So, El Nino can cause sea level will rise. However, this is a natural change that does not last. long. The global impact is much more serious. warming. Most climate models predict that sea level will continue to rise as a result of this factor a. And this already negatively affects the population of some species living in coastal areas.
