Prepare now for another major El Nino

The latest cyclical warming of Pacific Ocean waters, first observed centuries ago and formally tracked since 1950, began earlier this year and has already been felt across Asia, Africa and Latin America.

Weather experts predict this El Nino will continue into the spring of 2016 and could wreak havoc, because climate change is likely to exacerbate the intensity of storms and flooding in some places and of severe drought and water shortages in others. El Nino's impacts are global, with heavy rain and severe flooding expected in South America and scorching weather and drought conditions likely in the Horn of Africa region.

The risk is especially great for East Asia-Pacific countries that are highly vulnerable to altered weather patterns because of climate change. This year will likely be the hottest ever recorded, increasing the El Nino effect caused by weakened trade winds that fail to push warmer Pacific Ocean waters to the west.

We know what the potential effects might be. In 1997 and 1998, the strongest El Nino on record led to the deaths of 23,000 people from natural disasters, increased poverty rates by 15 percent in some countries and cost governments up to $45 billion owing to severe storms, droughts and other effects.

Such a global challenge calls for a global response - with coordinated efforts by governments, international institutions such as the World Bank, relief agencies and communities - to minimize the death and destruction from natural catastrophes while building more resilient societies.
