Traces of Giant, 2,700-Year-Old Solar Storm Detected in Greenland Ice By George Dvorsky

"Traces of Giant, 2,700-Year-Old Solar Storm Detected in Greenland Ice"

By George Dvorsky

"Evidence of an unusually strong solar storm that hit Earth in 660 BCE has been detected in Greenland ice cores—a finding which shows we still have lots to learn about these disruptive events.

An extreme form of solar storm, known as a solar proton event (SPE), struck our planet 2,679 years ago, according to new research published today in Proceedings of the National Academy of Sciences. If an event of such magnitude were to happen today, it would likely wreak havoc on our technological infrastructure, including communications and navigation. Lund University geologist Raimund Muscheler and his colleagues presented evidence in the form of elevated levels of beryllium-10 and chlorine-36 isotopes embedded within ancient Greenland ice cores.

but they can also be spotted as spikes of beryllium-10 and chlorine-36 in ancient ice cores. The authors of the new study said scientists tend to overemphasize carbon-14 at the expense of searching for other markers, and that “efforts to find [SPEs] based solely on [carbon-14] data likely lead to an underestimated number of such potentially devastating events for our society.”

SPEs are capable of temporarily degrading the Earth’s ozone layer, which allows excessive amounts of ultraviolet radiation to reach the ground. This is (moderately) bad for lifeforms on the surface, but it’s not the kind of thing that could trigger a mass extinction. As a risk, SPEs are a much bigger problem in terms of how they would affect our technologies; a sufficiently strong SPE poses “a threat to modern society in terms of communication and navigation systems, space technologies, and commercial aircraft operations,” according to the new study. These extreme space weather events could also be catastrophic for astronauts working in the International Space Station, who aren’t shielded by Earth’s atmosphere.

Importantly, SPEs are not to be confused with geomagnetic storms, which are a related, but distinct, phenomenon.

SPEs have been detected before, including events in Quebec (1989) and Sweden (2003) but the the newly discovered storm appears to have been stronger than anything seen with our modern instruments over the past 70 years. Indeed, we now have the tools to detect these events as they happen. For the new study, Muscheler and his colleagues analyzed two Greenland ice cores, finding spikes of both beryllium-10 and chlorine-36 in ice dated at 2,679 years old—evidence consistent with an SPE.

It’s now the third massive SPE known to scientists, the others occurring 1,245 and 1,025 years ago. This latest discovery means solar storms of this variety are likely happening more frequently than we thought—perhaps once every 1,000 years—but more data is required to create more reliable estimates.

SPEs happen in the wake of a massive solar flare or coronal mass ejection on the Sun. These stellar events send streams of particles, including high-energy protons, toward Earth, where they interact with the Earth’s atmosphere, triggering reactions that increase the rate of radionuclide production, including carbon-14, beryllium-10, and chlorine-36 (radionuclides are unstable atoms with excess nuclear energy). Traditionally, SPEs have been detected as spikes of carbon-14 in tree rings,"
