Powerful El Niño Developing in Pacific, Expected to Reshape Global Weather Patterns

A potentially record-breaking El Niño is developing in the tropical Pacific Ocean and is expected to emerge in the coming weeks, with forecasters warning it could be among the strongest in 140 years. The climate phenomenon occurs naturally every two to seven years when trade winds weaken, allowing warm water to accumulate, and its effects ripple globally through atmospheric changes. The event could trigger widespread drought, flooding, heat waves, and disruptions to food and water supplies across multiple regions, with potential economic losses in the trillions.

A powerful El Niño is developing in the Pacific Ocean and could become one of the strongest on record, according to forecasters including atmospheric scientists at major institutions. The World Meteorological Organization expects El Niño conditions to emerge soon and persist at least through winter. El Niño is a naturally occurring climate pattern that begins when trade winds weaken, allowing warm water to accumulate across an area roughly the size of the continental United States. Although localized to one ocean region, its effects propagate globally by altering the tropical atmosphere, which then influences weather patterns thousands of miles away. Regional impacts vary dramatically: parts of Central America, Asia, Africa, and Australia face increased drought risk and water shortages affecting agriculture and drinking water, while South American Pacific coasts risk torrential rainfall and flooding. The phenomenon is also expected to suppress Atlantic hurricane activity through increased wind shear, though storms that do develop could still cause catastrophic damage. Scientists warn of increased wildfire risks across Australia, Canada, the United States, and the Amazon rainforest.

Nobel Laureates Rebut Study Claiming Universe's Expansion Is Slowing, Confirm Acceleration Continues

An international team of astrophysicists, including Nobel laureates Adam Riess and Brian Schmidt, has published a study in the Monthly Notices of the Royal Astronomical Society confirming that the universe's expansion is still accelerating. The rebuttal targets a late-2024 South Korean study that had claimed dark energy was weakening, a finding that would have overturned nearly three decades of cosmological understanding. The new study identifies two specific methodological errors in the earlier work, restoring confidence in the standard model of cosmic acceleration while leaving the deeper mystery of what dark energy actually is unresolved.

Study Finds Trees May Store Less Carbon Than Climate Models Predict

A new study published in Science Advances found that oak trees stop growing months before they stop photosynthesizing, meaning increased carbon uptake does not necessarily translate into more wood growth and long-term carbon storage. Researchers analyzed 137 sites across the US, finding that 26–36% of annual carbon uptake occurred after tree growth had already ceased, with drought and heat identified as key triggers for halting growth. The findings suggest that widely used climate models, which assume photosynthesis and growth are tightly linked, may be overestimating forests' future capacity to sequester carbon.

San Andreas Fault Stress Reaches Highest Level in 1,000 Years, Study Finds

A new peer-reviewed study finds that tectonic stress on Southern California's San Andreas and San Jacinto fault systems has reached its highest levels in at least 1,000 years, with the San Jacinto-Bernardino section measuring 3.6 megapascals. The research, led by the University of Hawaiʻi at Mānoa and published in the Journal of Geophysical Research: Solid Earth, used a computer model drawing on geological data including radiocarbon dating and tree-ring records to reconstruct a millennium of earthquake history. The findings cannot predict when a major earthquake will occur but are intended to improve hazard assessments, inform building codes, and guide emergency preparedness in a region home to millions.
