El Niño

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.

California has declared a state of emergency covering the entire state as officials prepare for a strong El Niño forecast to bring heavy rain, flooding and storms. The declaration allows agencies to mobilise resources, pre-position equipment and respond quickly as conditions deteriorate. News coverage across the state is drawing wide attention as residents brace for severe winter weather.

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.

California Governor Gavin Newsom has declared a state of emergency for Kern County as a powerful El Niño-driven storm approaches the region. The move allows state resources to be mobilized quickly to support local response efforts. Residents in Bakersfield and surrounding communities are being urged to prepare for heavy rain, flooding and dangerous conditions.

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 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.

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

A new USGS overview examines how a strong Super El Niño event is affecting the Midwestern United States. The report outlines regional consequences of the climate pattern, which typically brings shifted precipitation and temperature conditions. With El Niño events capable of disrupting agriculture, water supplies and weather across the region, coverage of its Super El Niño intensity is drawing attention from farmers, planners and weather watchers.

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 say El Niño is driving a stark divide in tropical activity this hurricane season. The pattern has strengthened winds over the Atlantic, tearing storms apart and keeping that basin unusually calm, while warm Pacific waters are generating repeated hurricanes. Meteorologists expect the imbalance to persist as long as El Niño conditions hold through the season.
