**Belfast, UK -** Scientists have uncovered evidence of ancient solar storms, far more powerful than the Carrington Event of 1859, which disrupted telegraph systems worldwide. These extreme storms, detected through radiocarbon dating of ancient tree rings, pose a significant threat to our modern technological infrastructure.
A recent study, published in *Nature*, revealed that these events can cause abrupt spikes in radiocarbon levels in tree rings, acting as a unique fingerprint of solar storms. This method has unearthed several such events, including one in AD 774 that dwarfed the Carrington Event in intensity.
The study has also identified extreme solar storms in AD 993, 660BC, 5259BC and 7176BC, with the most powerful occurring around 14,370 years ago, towards the end of the last ice age. These storms could have caused widespread disruption to Earth’s magnetic field, potentially disrupting communication networks and global electricity grids.
“The strength of some past extreme solar storms detected in tree rings suggest they would have played havoc with our technological infrastructure on a scale never seen before,” said Professor Maarten Blaauw of Queen’s University Belfast.
The researchers emphasize that understanding these past events is crucial for preparing for future solar storms. While the exact frequency of these extreme storms is unknown, the scientific community is actively analyzing tree rings from across the globe to uncover more evidence and refine our understanding of these powerful events.
“Enhancing our understanding of these extreme events is not only important for precise radiocarbon dating but also for understanding processes happening on the Sun and on our own planet. It can also assist us in preparing for the next extreme solar storm,” said Professor Blaauw.
By analyzing the radiocarbon record, scientists aim to improve their forecasting capabilities and better protect our vital technological infrastructure from the potential devastation of a powerful solar storm. While the timing of the next event remains a mystery, the evidence suggests it is only a matter of time.
