El Niño’s Impact: $3 Trillion Loss to Global Economy

[ad_1]

El Niño could cost up to $3 trillion in damages through 2029

El Niño is a warm weather pattern that affects weather across the world. It can trigger flooding in some places and drought in others. This year’s El Niño is expected to form sometime between May and July. The World Meteorological Organization warns that El Niño, combined with climate change, could “push global temperatures into uncharted territory.”

The Potential Damage of El Niño

According to a study published in the journal Science, this year’s El Niño could take a $3 trillion toll on the global economy through 2029, based on past damages caused by El Niño and forecasts predicting a potentially severe event. The study authors from Dartmouth found that El Niño tends to hinder economic growth for years after the event occurs.

The Impact of El Niño on the Global Economy

The authors of the study analyzed the economic damage caused by two previous El Niño events. The 1982–83 El Niño cost the world $4.1 trillion in income loss over five years, and the 1997–1998 El Niño cost $5.7 trillion. The stress of these events was felt differently throughout the world. The United States saw its GDP decline by 3 percent even five years after each El Niño, while tropical countries like Peru and Indonesia saw their GDPs fall by more than 10 percent.

The Potential for an Intense El Niño

There are signals indicating that this year’s El Niño could be particularly intense. El Niño is just one part of a recurring climate pattern that includes a cooler counterpart, La Niña. This year, La Niña could influence El Niño, making it especially strong. Additionally, El Niño changes the flow of warm water in the Pacific Ocean, and there have been record high sea surface temperatures. This could potentially lead to a major economic toll that depresses economic growth in tropical countries for up to a decade.

Frequently Asked Questions (FAQ)

What is El Niño?

El Niño is a warm weather pattern that influences weather across the world. When it forms, it can trigger flooding in some regions and droughts in others.

What is the potential damage caused by El Niño?

According to a recent study, El Niño could cost the global economy up to $3 trillion in damages through 2029 based on past damages and forecasts of a potentially severe event.

How does El Niño affect the global economy?

El Niño tends to hinder economic growth for years after the event occurs, as seen from the estimated $4.1 trillion in global income loss over five years due to the 1982–83 El Niño and the $5.7 trillion in income loss due to the 1997–1998 El Niño. The impact of El Niño is felt differently throughout the world.

Could this year’s El Niño be especially strong?

Yes, there are signals indicating that this year’s El Niño could be particularly strong. El Niño is just one part of a recurring climate pattern that includes a cooler counterpart, La Niña. This year, La Niña could influence El Niño, leading to potentially high economic tolls that depress economic growth for up to a decade.

What is the potential impact of climate change on El Niño?

The World Meteorological Organization warns that El Niño, combined with climate change, could “push global temperatures into uncharted territory.”

Conclusion

El Niño is expected to form sometime between May and July, and this year’s event could be particularly strong. The projected economic toll could reach up to $3 trillion through 2029, according to a recent study. El Niño tends to hinder economic growth for years after the event occurs, and the impact is felt differently throughout the world. With the potential influence of climate change, El Niño’s impact on the global economy could have far-reaching consequences.
