El Niño’s Potential to Reshape Global Tropical Storm Activity in 2026

NOAA forecasts a quieter Atlantic hurricane season in 2026 because of El Niño, assigning a 55 % cha…
Season Outlook Under El Niño InfluenceThe 2026 Atlantic hurricane season has opened with NOAA projecting a quieter‑than‑usual period, driven primarily by an active El Niño. The agency cites a 55 % chance of below‑normal activity, a 35 % chance of near‑normal, and a 10 % chance of above‑normal storms.NOAA’s Forecast and the Mechanics of El NiñoEl Niño is the periodic warming of surface sea temperatures in the central and eastern tropical Pacific. This warming disrupts global wind and rainfall patterns, suppressing Atlantic hurricane formation while enhancing storm activity in the eastern Pacific. The phenomenon is part of the broader ENSO (El Niño‑Southern Oscillation) cycle, which alternates between El Niño, La Niña, and a neutral phase.Statistical Probabilities and Historical Impact55 % probability of below‑normal Atlantic activity for 2026.35 % probability of near‑normal activity.10 % probability of above‑normal activity.Average Atlantic season: 14 named storms and 7 hurricanes, including 3 major hurricanes.Historical El Niño years show a 60 % reduction in hurricane days and lower overall intensity.U.S. hurricane toll (1980‑2024): 7,211 deaths and roughly $1.55 trillion in economic losses.Regional Shifts in Storm Frequency and IntensityNorth Atlantic: Suppressed activity; fewer hurricane days.Northeast Pacific (near Hawaii): Increased storm formation; more systems drift toward the islands after an El Niño year.Australia & South Pacific: Fewer storms along Australia’s coast; formation zone shifts eastward toward the international dateline.Northwest Pacific (Asia): Total typhoon count remains stable, but genesis moves eastward, reducing impacts on the Asian mainland.Southwestern & Northern Indian Oceans: Little to no observable change in storm numbers.NOAA’s National Weather Service Director Ken Graham cautioned, “It only takes one storm to make for a very bad season,” emphasizing preparedness despite the overall quieter outlook.What the Rest of 2026 May Hold for Coastal CommunitiesEven with reduced probabilities, the risk of a high‑impact storm remains. Communities along the U.S. Gulf Coast, Caribbean islands, and Pacific rim should maintain vigilance, update evacuation plans, and monitor real‑time forecasts. The shifting storm tracks also mean regions traditionally less affected—such as parts of the South Pacific and Hawaii—may see increased activity, prompting broader regional coordination.

AI Weather Startup Outforecasts Government Agencies

WindBorne Systems, an AI weather startup founded by Stanford students, has released a new weather f…
The Rise of AI Weather Forecasting A new AI weather forecasting tool released by WindBorne Systems offers more frequent and accurate predictions on key variables than the world-leading system developed by European governments. This advancement is thanks to improvements in how sensor readings are fed into deep learning models. WeatherMesh-6: A More Accurate Forecast Founded by a group of Stanford students in 2019, WindBorne began by building a better weather balloon, with the idea of selling weather data. However, with the arrival of weather-forecasting deep learning models in 2022, the team realized they could capture more value by building their own model as well. Today marks the release of the sixth version of that model, WeatherMesh-6, which the company says is more accurate than traditional and AI forecasts produced by the ECMWF. The Data Advantage WindBorne has about 400 balloons in flight gathering sensor readings at any given time, launched from 15 sites around the globe. The advances in its current model come from improvements in how the data collected by the balloons is fed into the models. Outperforming Traditional Forecasts One simple way to understand it is that WeatherMesh-6 "is as accurate five days out as a traditional forecast is the day before," particularly on surface temperature measurements. WeatherMesh-6 produces a forecast every hour, as opposed to every six hours, as traditional models do, and its resolution is now down to 3 km in the continental U.S. The Future of Weather Forecasting The company suffered a scare last year when a United Airlines jetliner flew into one of its balloons. While the plane suffered minor damage, no one was hurt, in part because WindBorne followed U.S. regulations about how large its sensor package could be. Now, however, the company uses the global aviation surveillance system ADS-B to move its balloons out of the way of passing aircraft, in an effort to reduce the odds of another crash. Business Model and Funding WindBorne, which has raised $25 million in venture funding with a reported valuation of $85 million in 2024, sells its balloon data to NOAA, where it is used in the American weather forecasting enterprise, and the U.S. Air Force and Navy. The company also sells its forecasts to investors and commodity traders.

UN Warns Record‑Breaking Hot Year Likely by 2030

The UN’s World Meteorological Organization says a record‑breaking hot year is almost certain betwee…
The World Meteorological Organization, in a UN‑commissioned report, warns that a record‑breaking hot year is almost certain by 2030, with climate‑driven risks accelerating across the globe.UN WMO Warns of Near‑Certain Record‑Hot Year by 2030The report, produced by the UK Met Office for the WMO, highlights an 86 % chance that at least one year between 2026‑2030 will outstrip 2024 as the hottest on record. An El Niño expected later this year could push the global temperature record as early as 2027. Lead author Dr Leon Hermanson notes the El Niño will raise the odds of a 2027 record year.Probability Metrics Highlight Escalating Heat Risks86 % chance of at least one year 2026‑2030 surpassing 2024’s temperature.75 % chance that the five‑year average (2026‑2030) exceeds 1.5 °C above pre‑industrial levels.Less than 1 % chance of any single year in that span exceeding 2 °C.96 % chance of an El Niño event Dec 2026‑Feb 2027 (NOAA forecast).35 % chance of a “super” El Niño, amplifying heat extremes.Implications for Human Health, Economies and Climate PolicyGlobal heating already claims one life per minute, a toll set to rise without rapid emissions cuts.Extreme heatwaves are battering the UK, Europe, India and broader Asia, threatening lives and economic productivity.The Arctic is projected to warm 2.8 °C above recent averages over the next five winters—more than three times the global rate.Rainfall patterns will shift: northern Europe, the Sahel, Alaska and Siberia likely to become wetter, while the Amazon is expected to dry out.Outlook: El Niño, Policy Action and the Race to Stay Below 2°CUN climate chief Simon Stiell stresses that protecting lives and economies hinges on “kicking the fossil‑fuel addiction much faster.” Clean power is now cheaper than fossil fuels, but scaling it quickly is essential to keep the 2 °C target within reach and to avoid the catastrophic impacts of exceeding 1.5 °C.

US West Coast Marine Heatwave Alarms Scientists

A massive marine heatwave off the US west coast is alarming scientists due to its ecological and en…
The Marine Heatwave's Persistence and ExpansionAn enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists as new data shows its ecological and environmental effects are intensifying. The unusual area of warm water has persisted since peaking in size during September 2025 and still stretches thousands of miles from the California coastline – more than halfway across the Pacific – affecting a vast triangle-shaped region of oceanic habitats from Hawaii to British Columbia and southward to Mexico.The Event DetailsAs recently as early April, marine scientists had hoped that the heatwave might diminish and the worst of its effects may be avoided. However, new projections released last week by the National Oceanic and Atmospheric Administration (Noaa) show it is now expected to expand and strengthen in the months to come.The Data AnalysisScientists say the effects may already be far reaching. A surge in the marine heatwave would accompany the formation of El Niño in the tropical Pacific – resulting in an atmospheric and oceanic mélange that could influence everything from record-breaking temperatures on land to disrupted marine food chains.The Impact AnalysisAdditional data acquired in recent weeks has left climate scientists gobsmacked and re-examining their assumptions of how the complex interplay between the ocean and the atmosphere could accelerate the effects of human-caused climate crisis. Climate scientists said the persistent marine heatwave has contributed to shockingly extreme temperatures downstream across most of the United States.The Prediction“There’s real concern right now that even if this marine heatwave didn’t persist, we’re heading into a bad wildfire season with poor water supply conditions,” said Larry O’Neill, an Oregon State University climatologist. “Our summer is going to be much warmer than normal.”

Trump Weather Data Cuts Could Undermine Forecast Accuracy, Experts Warn

Experts warn that the Trump administration’s proposed 40% cut to NOAA funding and reductions in cli…
Executive Summary: Forecasts at Risk Amid Budget CutsAs the United States braces for an intense hurricane season and unprecedented summer heat, experts caution that the Trump administration’s proposed 40% reduction in NOAA funding and broader cuts to climate and weather data programs could make federal weather forecasts less reliable when they are needed most.Policy Changes Undermine Data‑Intensive AI ForecastingThe agency launched a suite of AI‑powered global weather models last year, promising faster and more accurate predictions. However, those models are trained on "centuries of weather data," a resource that is being eroded by staffing reductions, satellite de‑commissioning, and fewer balloon launches.NOAA AI model suite introduced late 2025 to improve speed, efficiency, and accuracy.Data cuts include scaling back satellite operations and balloon launches, threatening key observation systems.Budget proposal offers a modest increase for the National Weather Service but a 40% cut to NOAA overall.Financial Impact: The 40% NOAA Funding ReductionThe administration’s budget plan calls for a 40% cut to NOAA’s overall budget while only modestly increasing the National Weather Service’s allocation. This disparity reduces resources for data collection, climate research, and the maintenance of observation networks such as ocean buoys.Broader Consequences for Weather PreparednessReduced data collection hampers the ability of both traditional physics‑based models and newer AI models to predict extreme events. Experts note that AI models, which rely heavily on historical patterns, already "underperform" for unprecedented weather extremes, and further data loss could exacerbate this shortfall.Historical AI model performance lags behind physics‑based models for rare events like the February 2026 blizzard.Cutbacks to climate research threaten the skill of future forecasts, as highlighted by former NOAA chief scientist Craig McLean.Upcoming "super El Niño" conditions could amplify heat records and hurricane activity, increasing reliance on accurate forecasts.Future Outlook: Forecast Reliability and Policy ResponseAnalysts predict that unless the data cuts are reversed or mitigated, the reliability of federal weather forecasts will decline, especially for extreme events. While NOAA maintains that AI tools are an addition—not a replacement—to its existing model suite, the tension between budget constraints and the need for robust data persists. The agency is slated to release its 2026 Atlantic hurricane outlook soon, which will test the resilience of current forecasting capabilities under reduced data conditions.

Trump Expands Red Snapper Fishing Season Despite Overfishing Concerns

President Trump has approved expanded state permits for the 2026 recreational red snapper fishing s…
The Lead: Trump's Fishing Policy ExpansionPresident Donald Trump has approved all state permits for the 2026 recreational red snapper fishing season across southeastern coastal states, including Florida, Georgia, South Carolina, and North Carolina. The administration describes the decision as a "huge win" for fishermen, though conservation groups warn it could lead to overfishing and threaten the long-term sustainability of the fishery.The Policy Shift: Federal to State ControlThe Trump administration's decision centers on transferring greater authority to states for managing recreational red snapper fishing seasons. In a Truth Social post, Trump claimed that fishermen have been "punished with VERY short Federal fishing seasons despite RECORD HIGH fish populations and the States begging to oversee these permits."The policy involves coordination with the National Oceanic and Atmospheric Administration (NOAA), which has traditionally regulated fisheries and set quotas and seasons in federal waters. Under the new approach, states would have more flexibility in determining fishing seasons while catch limits and size requirements would still apply.The Conservation Background: From Crisis to RecoveryRecreational red snapper fishing has been tightly controlled at the federal level for decades due to historical overfishing. At its lowest point in the late 1990s and early 2000s, the red snapper spawning stock fell to about 11 percent of its historical level, prompting strict conservation measures under a long-term rebuilding plan set to run through 2044.Several southeastern states have since pushed for more flexibility, arguing that the population has recovered sufficiently to allow expanded fishing opportunities. Supporters of the policy change point to what they describe as a recovering red snapper population and suggest that state management would improve access for recreational fishermen.The State Management Approach: Lessons from the GulfA similar approach has already been implemented in the Gulf of Mexico, where states have taken on a larger role in managing recreational red snapper seasons. Governor Ron DeSantis of Florida has praised this state management model, stating that "State management and expansion of Gulf snapper season have been a major boon for our Gulf of America communities."Under the current system in the South Atlantic, anglers are typically limited to one fish per day. The expanded seasons would allow more fishing days while maintaining these catch limits, with proponents arguing that this balance protects the fishery while increasing recreational opportunities.The Scientific Warnings: Overfishing RisksDespite the administration's optimism, conservation groups like Ocean Conservancy have raised significant concerns about the potential for overfishing. The organization points to warning signs already emerging in the Gulf of Mexico, including a decline in the average size of fish and reports from anglers who must travel farther to catch keeper-sized fish."These exempted fishing permits are an end run around sustainable management," said Meredith Moore of Ocean Conservancy. "Just last year, NOAA's own analysis showed a two-day season was needed to prevent overfishing. There is no doubt that allowing months-long seasons will lead to overfishing."The group estimates that catches could reach 485,000 fish over a 39-day season, more than 20 times the annual federal limit of 22,797 fish for the South Atlantic. Such a catch, they warn, could not only violate federal regulations but also jeopardize the long-term health of the fishery.The Future Outlook: Balancing Access and ConservationThe debate over red snapper management reflects a broader tension between recreational access and conservation concerns. While anglers and some state officials welcome expanded fishing opportunities, scientists and conservation groups emphasize the need for caution given the fish's history of overexploitation."Overfishing means sacrificing the chance to teach the next generation to fish in order to fill coolers this season," warned JP Brooker of Ocean Conservancy. "Red snapper is a favourite of Floridians and out-of-state anglers. No one likes short fishing seasons, but if we don't follow the science and let these fish recover, we could soon lose this cherished fishing season for good."The outcome of this policy shift will likely depend on how effectively states can monitor and enforce fishing regulations, as well as the actual health of the red snapper population in the South Atlantic compared to the more robust Gulf stock.

El Niño Alert: Experts Warn of Potential 'Super El Niño' and Record Global Temperatures

There is a high likelihood that El Niño will emerge this summer, potentially leading to a 'super El…
Experts are closely monitoring climate patterns in the Pacific Ocean, which indicate a high chance of El Niño developing this summer. A strong El Niño event could lead to severe weather conditions, including super-charged rainstorms and droughts, depending on the region. A 'super El Niño' could push 2027 to break global heat records, according to climate scientists. This phenomenon occurs when ocean surface temperatures in the central and eastern tropical Pacific Ocean warm up, leading to significant impacts on global weather patterns. El Niño is characterized by warming of the ocean surface in the central and eastern tropical Pacific Ocean. It's one of three states scientists observe: La Niña, conversely, happens when sea surface temperatures are below average, and neutral conditions are defined when neither El Niño or La Niña are present and surface temperatures are about average. The 'El Niño-southern oscillation' (Enso) tends to develop during spring in the northern hemisphere and shifts every three to seven years. Warming and cooling at sea surface during El Niño and La Niña can range from 1C to 3C, and have enormous effects on precipitation, drought, heat, and climate disasters in different regions. Conditions are currently shifting from La Niña to a neutral pattern, according to the latest outlook from the US Climate Prediction Center. Models show a 62% chance El Niño will emerge this summer and linger until at least the end of the year. A super El Niño that occurred in 2015 brought severe drought in Ethiopia, water supply shortages in Puerto Rico, and smashed records after unleashing a vicious hurricane season in the central North Pacific. A 'super' El Niño means one that is stronger, typically defined by sea surface temperatures spiking up to at least 2C. Noaa scientists have given a 1 in 4 chance that this could happen by fall or winter, with the caveat that spring forecasts are sometimes muddled. Transitions in conditions that happen in the spring can make outcomes a bit harder to predict. Experts warn that a strong or super El Niño could lead to drought and heat across Australia, southern and central Africa, India, and parts of South America. Heavy precipitation, meanwhile, could hit the southern tier of the US, parts of the Middle East, and south-central Asia.

US March 2026 Sets Unprecedented Heat Records as Super El Niño Looms

In March 2026 the contiguous United States experienced its hottest month on record, shattering temp…
Federal weather data reveal that March 2026 was the hottest March ever recorded across the continental United States in a 132‑year dataset, with average temperatures soaring to 50.85 °F (10.47 °C), a staggering 9.35 °F (5.19 °C) above the 20th‑century March norm. This anomaly eclipsed the previous record of an 8.9 °F excess set in March 2012, marking the most extreme departure from average temperatures for any month in U.S. history. The month’s daytime highs were equally extreme, averaging 11.4 °F above the long‑term benchmark—almost a degree hotter than the typical April high, according to the National Oceanic and Atmospheric Administration (NOAA). Such extreme warmth is part of a broader trend: six of the ten most abnormal heat months have occurred within the last decade, and February 2026, at 6.57 °F above normal, ranked as the tenth most anomalous month on record. “The March heat wave was unprecedented across the United States,” noted Shel Winkley of Climate Central, emphasizing the sheer volume of records broken. In just two days (March 20‑21), roughly one‑third of the nation experienced temperatures that would have been virtually impossible without human‑induced climate change, according to Climate Central’s analysis. Data compiled by meteorologist Guy Walton shows that more than 19,800 daily temperature records were surpassed in March, and over 2,000 locations set new monthly heat records—a volume of record‑breaking events usually spread across entire decades. Jeff Masters of Yale Climate Connections warned that “climate change is kicking our butts,” adding that the January‑March period was the driest on record for the contiguous United States. The combination of extreme heat and historic dryness threatens water supplies, agriculture, river navigation, and overall ecosystem health. Looking ahead, both the European Copernicus climate service and NOAA project the formation of a “super” El Niño in the coming months, with the potential to amplify global temperatures into late 2026 and 2027. Meteorology professor Victor Gensini of Northern Illinois University cautioned that such an event could push the planet to new record‑high temperature thresholds.
