UN Warns of Extreme Weather as El Nino Looms

AI Summary
The United Nations' climate agency has warned of an increased risk of extreme weather due to the emerging El Nino weather pattern, with an 80% chance of occurring between June and August.

The El Nino Alert

The United Nations' climate agency has warned of an increased risk of extreme weather in the coming weeks and months due to the emerging El Nino weather pattern.

El Nino: What to Expect

The World Meteorological Organization (WMO) issued the alert in a news release on Tuesday, saying that there was an 80 percent chance of an El Nino event – marked by unusually warm sea surface temperatures in the central and eastern Pacific Ocean- between June and August and a roughly 90 percent chance of it forming by November.

Global Impacts

“The science is clear: El Nino is arriving on our doorstep in the coming months with 90 percent certainty,” said UN Secretary-General Antonio Guterres in a video statement. “The world must treat it as the urgent climate warning it is.”

Severe Weather Patterns

Bringing worldwide changes in winds, pressure and rainfall patterns, El Nino is a naturally occurring phenomenon that generally happens every two to seven years and lasts about nine to 12 months.

  • El Nino can trigger increased rainfall in the southern parts of South America and the United States, parts of the Horn of Africa and Central Asia.
  • It can also cause drought in Australia, Central America, Indonesia and parts of South Asia, and spur hurricane formation in the central and eastern Pacific, according to the WMO.

Impacts to ‘cross border with devastating speed’

The UN agency predicted this year’s El Nino phenomenon to be “at least moderate – and possibly strong”.

“Impacts will hit even harder, travel even farther, and cross borders with devastating speed,” said Guterres.

Future Outlook

The trend could help fuel especially severe wildfires this year, according to researchers at Imperial College London and the World Weather Attribution network of climate scientists.

In anticipation, the European Union has announced plans to deploy a record number of firefighters and aircraft in high-risk areas – spanning Cyprus, Greece, Italy, France, Spain and Portugal.
