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

The US National Oceanic and Atmospheric Administration officially declared on June 11, 2026 that El Niño conditions have formed in the tropical Pacific Ocean, with sea surface temperatures exceeding the 0.5°C-above-average threshold. NOAA gives a 63% probability that the event will intensify into a 'very strong' El Niño — defined as 2°C or more above average — between November 2026 and January 2027, which would rank among the largest on record since 1950; some climate models project temperatures could exceed 3°C above average. Layered on top of already record-high global temperatures driven by human-caused warming, the event is expected to trigger widespread droughts, floods, wildfires, and food supply disruptions across multiple continents, with 2027 widely forecast to become the hottest year on record.

NOAA's Climate Prediction Center issued an El Niño Advisory on June 11, 2026, confirming that ocean and atmospheric conditions in the tropical Pacific now meet the criteria for El Niño, with the Japan Meteorological Agency having made a similar declaration days earlier. The agency assigns a 63% chance of a 'very strong' event peaking in the November 2026–January 2027 window, a significant upgrade from prior forecasts; some US and European ECMWF models project Pacific sea surface temperatures could climb more than 3°C above average, which would surpass the 2.5°C record set during the 1982–83 event. Scientists emphasize that this El Niño is developing on a planet already approximately 1.37–1.39°C warmer than pre-industrial levels due to human activity, meaning regional temperature extremes could be unprecedented even by historical El Niño standards. Expected regional impacts include drought and wildfire risk across Australia, Indonesia, and northern South America; disrupted monsoons and intensified heat waves in India and Southeast Asia; flooding in parts of western South America, East Africa, Central Asia, and the southern United States; and a suppressed Atlantic hurricane season. The event is also projected to push global food supply chains under stress, particularly for maize and rice, while marine ecosystems face compounding pressure from El Niño-driven marine heat waves on top of already near-record ocean temperatures. NOAA also introduced a new monitoring tool, the Relative Oceanic Niño Index (RONI), which adjusts for long-term ocean warming trends to more accurately identify ENSO phases. UN Secretary-General António Guterres called the development 'an urgent climate warning,' urging accelerated action on fossil fuel emissions.

How coverage differed

The Guardian framed the El Niño primarily through a lens of global economic inequality, emphasizing how climate shocks disproportionately harm the world's poorest populations and are compounded by existing crises such as fertilizer shortages and supply chain vulnerabilities — a framing largely absent from centrist outlets. Most other sources, including BBC, AP, Reuters, and NOAA itself, focused on the meteorological facts, regional weather impacts, and probabilistic forecasts without the structural economic critique.

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.
