Muscheler’s team analysed two ice cores drilled from the Greenland ice sheet and found that both contained spikes in isotopes of beryllium and chlorine that date back to about 660BC. The material appears to be the radioactive remnants of a solar storm that battered the atmosphere.
The scientists calculate that the storm sent at least 10bn protons per square centimetre into the atmosphere. “A solar proton event of such magnitude occurring in modern times could result in severe disruption of satellite-based technologies, high frequency radio communication and space-based navigation systems,” they write in Proceedings of the National Academy of Sciences.
Britain’s emergency plans for severe space weather are based on a worst-case scenario that involves a repeat of the 1859 Carrington event. This was a powerful geomagnetic storm set off by a huge eruption on the sun known as a coronal mass ejection. A 2015 Cabinet Office report anticipated only 12 hours warning of a similar storm that could lead to power outages and other disruption.
The discovery of more powerful solar storms in the past 3,000 years suggests that space weather can be worse than the UK plans for. “The Carrington event is often used as a worst-case scenario, but our research shows that this probably under-estimates the risks,” said Muscheler.

Muscheler 的团队分析了从格陵兰冰原钻取的两个冰芯,发现两者都含有铍和氯的同位素尖峰,这可以追溯到公元前 660 年左右。这些物质似乎是太阳风暴的放射性残留物,太阳风暴曾重创大气层。
科学家们计算出,风暴向大气中每平方厘米至少释放了 100 亿个质子。他们在《美国国家科学院院刊》(Proceedings of the National Academy of Sciences)上写道:“现代发生如此大规模的太阳质子事件,可能会严重破坏卫星技术、高频无线电通信和天基导航系统。”
英国对恶劣太空天气的应急计划是基于最坏的情况,即 1859 年卡灵顿事件的重演。这是一场强大的地磁风暴,由太阳上被称为日冕物质抛射的巨大喷发引发。2015 年内阁府一份报告预计,类似的风暴可能会导致停电和其他破坏,预警时间仅为 12 小时。
在过去 3000 年里发现的更强大的太阳风暴表明,太空天气可能比英国计划的还要糟糕。“卡灵顿事件通常被用作最坏的情况,但我们的研究表明,这可能低估了风险,”Muscheler 说。
