"Summary": "<p>While the 11-year sunspot cycle is widely known, fewer are aware of the longer-term Gleissberg Cycle—a slower, centennial-scale rhythm that modulates solar activity. Roughly every 80 to 100 years, it suppresses sunspot numbers, as seen in the subdued Solar Cycle 24 around 2012–2013. According to recent findings published in Space Weather, the minimum of this cycle may have just passed. If so, we could be entering a multi-decade period of intensifying solar cycles. Historically, peaks following Gleissberg minimums have coincided with powerful solar events—such as the 1989 geomagnetic storm that shut down power across Quebec and, further back, the Carrington Event of 1859, which disrupted telegraph systems. But this time, the stakes are much higher. Society today is vastly more electrified and digitized, with exponentially more satellites, connected infrastructure, and vulnerable electronics. Future solar superstorms could have far more widespread and disruptive consequences.</p>",
