Forecasting a solar storm is a little like watching a wave leave a distant coast and trying to guess when it will reach the beach. Scientists can see a coronal mass ejection (CME) leave the Sun, but its speed and shape can change as it crosses space. By the time it reaches Earth, the warning […]

NASA says a new four-spacecraft mission has completed an early test that could make one of the hardest parts of space-weather forecasting much more precise: estimating when a solar eruption will reach Earth. In a proof-of-concept exercise announced on August 4, NASA’s PUNCH mission used continuous images of a coronal mass ejection, or CME, to […]

In May 2024, the strongest geomagnetic storm in two decades pushed the Northern Lights far enough south to become visible across much of the UK and beyond. Now, a study that appeared in Royal Society Open Science reveals that the incident also exposed important gaps in how the UK monitors and prepares its power grid, satellites, and aviation for future extreme space weather.

The storm reached a G5 rating, which is the highest level on the geomagnetic storm scale used by NOAA, as a result of five coronal mass ejections reaching Earth within a period of two days. Researchers with the Space Environment Impacts Expert Group (SEIEG) stated that although the storm caused only relatively minor disruption, it revealed shortcomings in the UK’s capacity to monitor and prepare for more severe space weather events.

The SEIEG then made 14 recommendations to the UK government addressing matters such as grid monitoring, satellite operations, and space weather forecasting. Richard Horne, chair of SEIEG and head of space weather at the British Antarctic Survey, recently gave a presentation on the findings at the Royal Astronomical Society’s National Astronomy Meeting in Birmingham.

A Storm That Tested the Limits

Researchers estimate that the May 2024 storm was a one-in-13-year event. By contrast, a Carrington-class storm, like the 1859 event that defines the standard for extreme space weather, has about a 1% chance of occurring in any given year. This means that a much more disruptive storm is still possible. The SEIEG report uses the 2024 storm as a practical example to assess how prepared the UK is for a more severe event.

“The Northern Lights were the most visible sign of the May 2024 storm, but they were only one part of a much broader space weather event that tested the UK’s critical infrastructure. The storm highlighted where we need better monitoring, better forecasting and more research so we’re prepared for a more severe event in the future,” Horne said.

The Blind Spot in Britain’s Power Grid

Geomagnetic storms create electric fields at Earth’s surface that can drive geomagnetically induced currents (GICs) through long conductive systems, including power transmission networks. High levels of GICs can overheat transformers, disrupt their normal function, and in severe cases cause damage that may lead to failures across parts of the power grid.

Currently, there are no GIC monitors in operation in England or Wales. The SEIEG report recommends establishing a network of monitors to assess how much current various transformer designs can tolerate before sustaining damage.

New Zealand as the Model

The report cites New Zealand as an example of effective monitoring. Since it is at a similar geomagnetic latitude, the country faces similar space weather risks, and its grid operators monitor around 93 transformers across 28 substations. Unlike in England and Wales, where monitoring is absent, these operators have verified their models using actual measurements and implemented operational mitigation procedures during the May 2024 storm.

Crowded Skies, Rising Risk

The storm also affected satellites in orbit. Almost 5,000 satellites adjusted their orbits during the storm. Satellites licensed in the UK saw their number of collision warnings rise by 35%. Since there are now so many objects in low-Earth orbit, a serious storm could raise the risk of collisions, possibly resulting in debris and causing additional incidents.

Preparing for Future Storms

SEIEG also recommends improving forecasts of coronal mass ejections and solar energetic particle events to provide two to three hours of warning before severe geomagnetic storms reach Earth. Improved forecasts could allow grid operators, satellite controllers, and airlines to take protective measures before severe geomagnetic storms arrive. 

“One of the biggest lessons from the May 2024 storm is that we still have important gaps in our monitoring and understanding of how severe space weather could affect UK infrastructure,” said Horne. “We were fortunate that this was not a one-in-100-year event. We now have an opportunity to strengthen our monitoring, improve our forecasts and make sure the UK is better prepared before a much larger storm occurs.”

The 14 recommendations are now under review by the UK government. Whether these steps will be taken before a Carrington-scale storm occurs remains uncertain. With this extreme class of storms remaining a realistic possibility, the researchers argue that improving monitoring and forecasting now could reduce the impact of a future extreme event.

A newly published study reports that tropical cyclones were far more common during the Late Paleozoic Ice Age than many climate reconstructions have suggested. Led by Yan, Macarewich, Jiang, and colleagues, the work appears in Nature Communications (2026) and reframes how Earth’s cold interval coexisted with warm-water storm systems.

The researchers investigated geological signatures linked to extreme marine events, combining stratigraphic evidence with climate-model constraints. Their goal was to distinguish ordinary seasonal variability from the kind of widespread, repeated disturbances that characterize tropical cyclone belts.

A key technical advance in the study is the integration of paleoclimate boundary conditions with storm-resolving dynamical reasoning. Instead of treating cyclone activity as a simple function of temperature alone, the team considered large-scale patterns that govern where warm oceans can persist long enough to power rotating storms.

The results point to an expanded region of conditions favorable for cyclogenesis. Even though the planet was globally in an ice-age mode, ocean–atmosphere coupling—driven by uneven heat storage, changing circulation, and shifting storm tracks—likely enabled tropical systems to form across parts of the tropics more frequently than expected.

The authors describe “widespread” activity, implying that cyclone impacts were not limited to rare episodes. This interpretation aligns with the idea that cooling did not fully suppress tropical cyclone energetics; rather, it altered the geography and intensity distribution of storm-prone environments.

Using the preserved sedimentary record, the study connects storm activity to repeated depositional pulses. Those pulses, they argue, reflect basin-scale disturbance rather than local weather anomalies, strengthening the case for frequent tropical cyclone events during this interval.

From a broader perspective, the findings have implications for how we understand resilience and feedbacks in past climates. If cyclones continued to thrive under ice-age background states, then tropical extremes may persist through major global reorganizations.

The study’s viral potential is clear: it challenges an intuitive narrative that “ice ages mean calm tropics,” and replaces it with a more nuanced picture in which warm-water dynamics and circulation shifts can sustain storminess despite global cooling.

A new study shows how changes in ocean circulation could reshape global rainfall patterns. A storm reaching California can begin with changes thousands of miles away in the Atlantic Ocean. Climate modeling suggests that as one of the planet’s major ocean circulation systems weakens, more moisture could be directed toward the West Coast while snowfall [...]
