Hurricane: El Niño

El Nino may be returning to warm water that affects the global tropical Pacific Ocean. This change may imply recurrence of the El Niño phenomenon which may affect the weather of the earth. The Federal Global Warming Prediction Center reported this global warming on Thursday of the US Oceanic and Atmospheric Administration. Agency stated that El Niño (pronounced as El NEEN-yo) may occur in the early spring, but in the late summer it is unlikely that it affects the US from autumn to the next winter.

Coral reefs are caused by various factors such as natural phenomena such as hurricane, El Niño, illness, overfishing, destructive fishing methods, coastal development, pollution, inadvertent regional threats, and the impact of global warming - the sea of ​​global warming It is threatened by. And an increase in the carbon dioxide content in the water. According to the World Resources Institute report, according to Reefs at Risk Revisited, 75% of the world's coral reefs are threatened by domestic and foreign pressures. About a quarter of them are damaged and can not be repaired. As we continue to work as usual, 90% of coral reefs will be in danger by 2030 and nearly all coral reefs will be in danger by 2050.

Historically, declines in corals around the world are related to the El Niño phenomenon, which usually raise the global temperature. The first massive coral decline was observed during the severe El Niño phenomenon in 1983, and the first truly global event was consistent with the 1998 strong El Nino phenomenon. The tropical coral reefs of the world are still affected by the 2010 El Nino phenomenon which is moderate in strength. Experts say that coral bleaching activity in 2014 - 2017 is not only due to its long period but also because it is not entirely due to the El Nino phenomenon. Although El Niño is expected in 2014, it was not realized until March 2015, but by that time the level of thermal stress at bleach level is already in progress. The strong El Nino phenomenon occurred in 2016. At the beginning of 2017, 51% of the world's coral reef showed thermal stress when Lanina was set up.

The El Niño phenomenon in 1982-83 has received much attention from the scientific community. Abnominally between 1991 and 1995, the El Nino phenomenon rarely developed so rapidly. The particularly intense El Niño phenomenon in 1998 killed about 16% of the world's coral reef system. This event temporarily raised the temperature by 1.5 ° C, but phenomena related to the ElNiño phenomenon usually rose 0.25 ° C. Since then, large-scale coral bleaching has become widespread all over the world, "serious whitening" has occurred in all areas.
