Geomagnetic storms push currents through long metal conductors—power lines, pipelines, and submarine cables—potentially tripping transformers and collapsing grids for months, even though people indoors are largely unaffected; historical events like 1989 Quebec and 1859 Carrington show the risk, and modern warnings plus operational measures can mitigate damage, though a Carrington-scale storm remains a serious threat.
Lumen, a 911 service provider, attributed the recent 911 outages in Nevada, South Dakota, Nebraska, and Texas to a third-party company's mistake during the installation of a light pole, which was unrelated to their services. While most of the service has been restored, the cause of the outages remains unclear, prompting concerns about the vulnerability of the nation's 911 infrastructure to cyberattacks. Law enforcement agencies in affected states have advised residents to use alternative methods such as texting 911 or using landlines during outages, and the Federal Communications Commission is currently investigating the situation.
New research reveals that the strength of solar storms hitting Earth can vary significantly over short distances, highlighting the need for a denser magnetometer network to better understand the complex structure of the magnetic field during solar storms. Currently, monitoring networks for solar storms have sensors spaced about 250 miles apart, but the study found that solar storm strength varies across much smaller ranges of around 62 miles. A more comprehensive network would provide local warnings of solar storm movements and better safeguard infrastructure vulnerable to magnetic disturbances.
Flash floods caused by heavy rainfall in New York City and the Hudson Valley have led to one reported death, destroyed infrastructure, and prompted a state of emergency. The severe weather has resulted in flooded and washed-out roads, power outages, flight disruptions, and travel disruptions. The inadequate infrastructure and drainage system in the city have contributed to its vulnerability to flooding. The National Weather Service warns of continued flash flood threats in the region, and Vermont has also declared a state of emergency in anticipation of the storms.
A strong solar storm hitting Earth could potentially cause a widespread internet outage, as magnetic fields unleashed by a solar superstorm could disrupt human infrastructure. Experts warn that our interconnected world may not be adequately prepared for such an event, which has not yet occurred in the digital age. Severe solar storms have historically caused disruptions, such as the Carrington Event in 1859 and a storm that took out the Quebec power grid in 1989. As the sun enters a particularly active period known as the "solar maximum" in 2025, concerns are growing about the vulnerability of our internet infrastructure. Research on widespread internet failure due to solar storms is limited, and the potential economic impact of even a single day of lost connectivity in the United States is estimated to be over $11 billion. Governments and companies need to pay attention to this threat and plan defenses to ensure the long-term resilience of the internet.
