14,000 years ago, the most powerful solar storm ever recorded hit Earth. 'This event establishes a new worst-case scenario'

New SOCOL:14C-Ex model reveals that the Late-Glacial radiocarbon spike in 12350 BC was caused by the record-strong extreme solar storm

The solar storm, the only known to have taken place in the last Ice Age, long eluded scientists as they lacked appropriate models for interpreting radiocarbon data from glacial climate conditions.

But a new study by a team from the Oulu University in Finland has taken a stab at the measurement interpretation with eye-opening results. Using a novel chemistry-climate model, the team found that the marked spike in the carbon-14 isotope detected in fossilized tree rings was caused by a solar storm more than 500 times as powerful as the 2003 Halloween Solar Storm, which was the most intense in modern history.

In 2023, a major spike in radiocarbon concentrations in fossilized tree rings was discovered, indicating a major solar storm must have taken place as the last ice age was drawing to an end.

Scientists previously studied records of five other radiocarbon spikes found in tree ring data, which they attributed to powerful solar storms that had taken place in 994 AD, 775 AD, 663 BC, 5259 BC and 7176 BC.
