another solar surge is on its way. We know that during the current solar minimum sunspots are infrequent, but, like the unexpected flare which took us by surprise on July 7th this year, coronal mass ejections (CMEs) can play havoc with our geomagnetic systems. Now that we are (practically) all on the same grid (electrical, telecommunications, satellite, computer, transport, GPS navigation), power-driven systems are extremely susceptible to solar storms. It's not just snow freezing the light cables and clogging the plumbing: a mass power failure would not be a good thing while temperatures are as low as they are at present. We might suddenly come to the scary realization that the wall is very thin between us who are dependent on our winter heating systems for warmth and the homeless man lying wrapped in newspaper under the freeway.
