El Niño

New data indicates the current El Niño is the strongest ever recorded, driving a major shift in global weather patterns. The development is expected to bring hotter temperatures, droughts and flooding to many regions, and scientists are watching closely for knock-on effects on agriculture, storms and global climate over the coming months.

A new report says global temperatures have reached record highs as the El Niño climate pattern strengthens in the Pacific. El Niño, which warms ocean surface waters and alters weather worldwide, is adding to the underlying warming trend driven by greenhouse gas emissions. Scientists warn the combination could push average temperatures to new extremes in the coming months, with implications for heatwaves, droughts and storms across many regions.

Hurricane Polo has intensified to rank among the strongest storms ever recorded, with El Niño conditions cited as the driver behind its unusual strength. The storm's rapid strengthening is drawing attention to how warming Pacific waters linked to El Niño can supercharge tropical cyclones, prompting questions about what it signals for the rest of the hurricane season.

A New York Times opinion piece warns that the current strong El Niño, a warming of the tropical Pacific that shifts global weather patterns, is set to drive severe conditions including heatwaves, droughts, floods and storms across many regions. The author urges governments and the public to prepare now for the disruption, arguing that early planning could limit the damage as the phenomenon reaches full strength in the coming months.

Powerful storms are striking opposite sides of the United States at the same time, and forecasters point to El Niño as the driving force. The climate pattern, marked by warmer Pacific waters, is reshaping jet stream paths and steering severe weather toward both the West and East coasts, prompting warnings and preparedness efforts nationwide.

A New York Times opinion piece argues that the emerging super El Niño, while expected to bring severe weather impacts worldwide, gives governments and communities valuable lead time to prepare. The author urges using the advance warning to strengthen defenses against likely heatwaves, droughts, floods and other disruptions linked to the climate pattern.

El Niño conditions are driving an unusual split in hurricane activity: the Pacific is producing storms at a vigorous pace while the Atlantic hurricane season remains unusually calm. Forecasters attribute the contrast to El Niño's strengthening of winds that tear Atlantic storms apart, while simultaneously fueling storm development in the warmer Pacific. The pattern is shaping expectations for the rest of the season.

The Atlantic has yet to produce a hurricane this season, and climate outlet Grist attributes the calm to El Niño. The phenomenon, which is driving record ocean temperatures worldwide, creates wind shear over the Atlantic that suppresses tropical storm development. The piece notes the irony that the same pattern raising global temperatures is also canceling Atlantic tropical activity, at least for now.

The Guardian has published an explainer on El Niño, the periodic warming of sea surface temperatures in the tropical Pacific that can drive droughts, floods and heatwaves across the globe. The piece outlines what causes the phenomenon, how it disrupts weather patterns, and what steps communities and governments can take to reduce the risks it poses.

California is preparing for flooding and landslides as forecasters expect a strong El Niño this year, a warming of equatorial Pacific waters that disrupts weather worldwide. After years of coastal erosion — with Pacifica, south of San Francisco, already hit — officials warn the storms the pattern typically brings could prove especially damaging to weakened coastlines and hillsides.

The El Niño climate pattern is influencing weather on opposite coasts of the United States, shaping storm tracks and conditions on both sides of the country, according to reporting by The New York Times. The pattern typically suppresses Atlantic hurricane activity while boosting storms across the southern tier of the nation and altering West Coast weather.

Forecasters put the odds of El Niño persisting for the next six months at nearly certain, with the probability edging from 100% down to 99%. The climate pattern, marked by warmer Pacific waters, typically brings altered weather worldwide, including droughts in some regions and heavy rainfall in others. Coverage is focused on what the extended outlook could mean for temperatures, storms and agriculture in the months ahead.

California has declared a state of emergency covering the entire state as officials brace for a strong El Niño forecast. The move allows state agencies to mobilise resources, equipment and personnel ahead of what is expected to be a period of heavy storms and flooding risk. The announcement has drawn wide attention as residents prepare for severe weather across the region.

California is looking to turn a potentially wet El Niño winter into an opportunity, pursuing efforts to capture stormwater from the big storms expected to hit the state. Officials want to store runoff to recharge groundwater supplies and boost reservoirs, rather than letting it flow out to sea, as drought-strained water systems seek any advantage from the pattern.

A study published in Science argues that a Mega El Niño pattern, producing extreme and prolonged climate swings, triggered the end-Permian mass extinction around 252 million years ago, the deadliest extinction event in Earth's history. The researchers say runaway warming destabilised ecosystems beyond what species could tolerate. The paper is being shared widely, with an open-access version of the full text available.

California is preparing for a series of storms linked to the developing El Niño pattern, which typically brings wetter conditions to the state. Officials and residents are watching forecasts closely, with concerns focused on heavy rain, flooding, and mudslides in areas recently affected by wildfires. Weather agencies are urging people to get ready for potential disruptions.

California Governor Gavin Newsom has declared a state of emergency for Kern County as a powerful El Niño-driven storm approaches the region. The declaration allows state resources to be mobilized quickly to protect residents and infrastructure. Local outlets in Bakersfield are urging residents to prepare for heavy rain, strong winds and possible flooding, with officials warning of hazardous conditions in the coming days.

The USGS has published an assessment of regional impacts from a super El Niño event, focusing on the Southwestern United States. The outlook highlights heightened risks for the region, which typically faces heavier rainfall, flooding and storm damage during strong El Niño episodes. Interest is focused on what the strengthened pattern could mean for water supplies, infrastructure and communities across the Southwest.

A letter to the editor argues that the developing El Niño will increase baseline sea levels, adding to seasonal coastal flood risks. The claim aligns with scientific expectations that El Niño conditions raise Pacific ocean temperatures and temporarily lift global sea-surface heights, though no specific figures or locations are given in the letter itself.

A strong, or 'super', El Niño event is being linked to significant regional weather impacts across the Midwestern United States. The phenomenon, driven by unusually warm Pacific Ocean waters, typically alters precipitation and temperature patterns, affecting the Midwest's agriculture, flooding risks and winter conditions. Attention is focused on how this cycle may play out differently for the region.

T. Rowe Price is working to ringfence its $165 billion emerging markets book from the potential fallout of El Niño, Bloomberg reports. The asset manager is assessing how the weather pattern could hit commodity producers, food prices and inflation across developing economies. The move highlights growing investor concern that climate-driven weather shocks could destabilize emerging market assets.

KESQ's Weather Insider segment examines the satellites used to study the world's oceans and monitor El Niño conditions. The piece explains how space-based observation of sea surface temperatures and ocean patterns helps forecasters understand and predict El Niño's effects on global weather. It highlights the role of satellite technology in improving weather and climate forecasting.
