It was during the same year that Charles Darwin published On the Origin of Species that one of the most powerful solar storms to be recorded in Earth’s history had occurred. Telegraph systems throughout Europe and North America failed, leading to fires in a number of places. It had been two years since the first verified sighting of a solar flare-a massive outpouring of Sun radiation-in 1859; it is now known by its name of Carrington event. It lit spectacular auroras on the skies, and it marked the beginning of the storm from the sun. The intensity of the Carrington event suggests that much more severe solar storms have occurred in the past.
Radiocarbon Clues from Tree Rings
Tree rings with varying radiocarbon levels now prove to be a clue to the ancient storms. Those sharp spikes in radiocarbon concentrations signal intense solar storms. The findings include events as early as AD774, AD993, and yet even earlier, in 660BC and 5259BC. This was much more potent than the Carrington event; the most intense recorded storm took place around 14,370 years ago, close to the last ice age.
Effects on Today’s Technology
Solar storms occur when charged particles that are released from the Sun penetrate through the Earth’s magnetic field. Solar storms can affect our technology by knocking satellites, destroying parts of power grids, and disrupting communication networks. These events suggest that our modern world would be rather vulnerable to this event. After all, when it is gradually being realized that solar storms that can cripple global systems are more frequent than earlier presuppositions, ancient trees around the world have been studied to better understand how often and with what intensity these solar storms hit the Earth. Not only does it advance radiocarbon dating, but it also better prepares us to face possible solar storms that might ravage the system of a much more interconnected society in the future.
