Researchers warn that El Nino will take place this year and it will be one of the worst recorded so far. An unexpected increase in the temperature of the Pacific Ocean indicate that experts had more optimistic estimates than reality.
El Nino, a phenomenon produced by heating of the water in the Pacific Ocean affect the climate in different parts of the world, producing droughts or floods and storms.
Wenju Cai, expert in climatology at Australia's Commonwealth Scientific and Industrial Research Organisation, said that this year the recorded temperatures in the Pacific are above those seen in previous years that held El Nino phenomenon.
In addition, El Nino will occur much earlier than originally estimated, like in the coming months and the chances of this real phenomenon are real over 70%, according to the Bureau of Meteorology in Australia.
So far, a strong El Nino occurred at every 20 years, but because of global warming, the phenomenon will take place from now on, once about 10 years, as the experts believe.
The worst El Nino recorded so far took place in 1997-1998 and caused catastrophic flooding in China, resulting with the deaths of over 1,500 people.
Damages of teh materials produced globally totaled about 45 billion dollars, and the total number of victims was 23,000.
An extreme El Nino occurs when water temperature rises above 18 Pacific degrees. Because of this, the atmosphere is releasing more heat and humidity, affecting global climate.
Thus, in some areas will record drought, wildfires and heat, and in other areas will be heavy rains and devastating floods.
Opposite phenomenon is called La Nina and occurs when the ocean temperature decreases.
