El Niño Officially Begins, Expected to Be One of the Strongest This Century, Warns NOAA
The National Oceanic and Atmospheric Administration (NOAA) has confirmed the onset of El Niño, a climate phenomenon that could become the strongest of this century, according to meteorologists. This development is expected to trigger extreme weather events globally, including droughts and heavy rainfall, with significant implications for agriculture and food security.
What Is El Niño and How Does It Work?
El Niño is a naturally occurring weather pattern characterized by the warming of surface waters in the central and eastern Pacific Ocean. During this phase, trade winds that typically push warm water westward weaken or reverse, causing a shift in atmospheric circulation. This redistribution of heat and moisture affects weather systems worldwide, according to NOAA.
“El Niño does not follow a strict timeline, but it typically occurs every two to seven years,” said Weston Anderson, a climate scientist at the University of Maryland. “The name ‘El Niño,’ meaning ‘the little boy’ in Spanish, originated from South American fishermen who noticed warmer waters around Christmas, linking it to the birth of Jesus Christ.”
Why This El Niño Is a Concern for Global Weather
El Niño conditions are expected to peak in December 2024 or January 2025, with NOAA reporting a high likelihood of a “very strong” event. Surface temperatures in the Pacific could rise by more than 2 degrees Celsius, though some agencies, like the World Meteorological Organization (WMO), avoid labeling it a “super” El Niño.
“The interaction between El Niño and global warming is still being studied,” said Jennifer Burney, a professor at Stanford’s Doerr School of Sustainability. “We’re seeing shifts in where extreme weather events occur, and the severity is likely to be higher in a warmer climate.”
How Will El Niño Impact Agriculture and Food Security?
El Niño’s effects on agriculture vary by region. In India, a weaker monsoon season could reduce rice production, while southern Africa faces drier conditions that threaten maize yields. Meanwhile, the U.S. is expected to experience wetter-than-normal weather, increasing flood risks in states from California to the eastern seaboard.
“Local governments may have adaptive strategies, such as shifting crop planting schedules or increasing imports,” Burney noted. “However, small-scale farmers—whose livelihoods depend on agriculture—may still face economic challenges.”
The 2023-2024 El Niño, classified as one of the five strongest on record by the WMO, contributed to 2024 being the hottest year on record. This year’s event comes amid ongoing global challenges, including fertilizer shortages linked to tensions in the Strait of Hormuz, which have already raised input costs for farmers.
Historical Context: El Niño and Global Famine
Historical data shows El Niño’s potential for devastation. The 1877 event, one of the strongest on record, triggered droughts across Asia, Brazil, and Africa, exacerbating famines that killed an estimated 50 million people. “These events highlight the need for preparedness, especially as climate change amplifies risks,” said Deepti Singh, an associate professor at Washington State University.
“Preparedness isn’t just about having supplies,” said Kelly Hayes, a climate resilience expert. “It’s about understanding how these events will affect communities and ecosystems.”
What’s Next for 2024 and Beyond?
Scientists continue to monitor how this El Niño will interact with ongoing climate trends. While the exact impacts remain uncertain, the combination of El Niño and rising global temperatures is expected to increase the frequency and intensity of extreme weather.
“The key takeaway is that we must act now to build resilience,” Singh said. “This isn’t just about weather—it’s about safeguarding food systems and vulnerable populations.”
