Solar storm hits Earth
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
A solar storm hit Earth, disrupting GPS readings by up to 33 feet. Scientists warn this could crash self-driving cars and affect power grids.
Background
Solar storms occur when the Sun releases charged particles that interact with Earth's magnetic field. A severe storm in November 2025 caused GPS errors and power grid disturbances. New research suggests such storms could have stronger impacts than previously thought, affecting technology and infrastructure.
How it unfolded
- May 2024A major solar storm caused auroras and disrupted radio signals, with GPS errors and satellite issues.
- Nov 2025A severe solar storm, the strongest in over two decades, hit Earth, causing GPS glitches and power grid disturbances.
- recentlyResearchers report that GPS readings across the US veered off by up to 33 feet, and new studies highlight potential risks to power grids and aviation.
Who’s saying what
- Scientists
- Researchers are alarmed by the GPS errors, noting they could crash self-driving cars and cause significant economic losses.
- Risk Analysts
- Experts like Ed Oughton are mapping where severe solar storms could strike the US power grid, emphasizing the need for preparation.
Still unverified
The claim that GPS errors could directly cause self-driving car crashes is based on research but not yet observed in real-world incidents.
