The phenomenon of El Nino is a complex and multifaceted event that occurs in the Pacific Ocean, characterized by a warming of the ocean surface temperature. This is caused by a weakening or reversal of the trade winds, which normally blow from east to west and transport warm water to Asia and Oceania.
The trade winds play a crucial role in maintaining the balance of the Earth's climate system, and their weakening or reversal has far-reaching consequences for the climate and weather patterns around the world. In South America, El Nino leads to warmer ocean water and heavy rains, while in Asia and Oceania, it increases the risk of droughts.
The effects of El Nino are exacerbated by climate change, which has already caused a rise in ocean surface temperatures of 0.9°C since pre-industrial times. With El Nino adding to this warming, the consequences for marine life are severe, reducing the ocean's ability to absorb CO2 and exacerbating the effects of climate change.
