El Niño could claim 450,000 lives in six months

 The consequences of ocean warming will most severely affect Nigeria, Indonesia, Sudan, India, and Brazil, where extreme heat is forecast.

El Niño occurs when Pacific Ocean waters warm, altering weather patterns worldwide: some regions experience droughts, while others face floods.

 Furthermore, the "super El Niño" is expected to persist into the spring of 2027, leading to an even higher final death toll. Forecasts indicate that global land temperatures will exceed the norm by 1.2 degrees in the coming months—a level scientists had not anticipated reaching for another 20 years.
