In 2011, the climate phenomenon La Nina was so strong that it has led to a drop in global sea level by 5 millimeters. This fact is contrary to the general trend: since the beginning of the 1990s the world's oceans rising by about 3 millimeters per year.

It turned out that in a time of increased La Niña occurred temporary movement of water masses from the ocean to the land. For a designated period was characterized by an increase in rainfall over Australia, northern South America and Southeast Asia. While the rains over the ocean were less common, the website

La Niña cycle — is the opposite phase of the climatic phenomenon El Niño. It is characterized by large-scale reduction of sea surface temperatures in the central and eastern tropical Pacific Ocean. During El Niño temperature, on the contrary, increased.

These variations strongly influence the climate and precipitation patterns around the world. For example, El Niño can lead to the fact that sea level rise. However, this is a natural change that does not last long. Much more seriously affected by global warming. Most climate models predict that global sea levels will continue to rise due to this factor. And this is a negative impact on the populations of some species found in coastal areas.
