It has already began. Auroras are dancing around the poles in response to the high-speed solar wind stream buffeting Earth's magnetic field.
In 1859 a huge solar storm burned out telegraph wires across Europe
and the United States. Dr Stuart Clark has written a book, The Sun
Kings, about when that happened. He says that the "Carrington flare", as
it was known, "smothered two-thirds of the Earth's skies in a blood-red
aurora a night later, and crippled all of global navigation and global
communication, such as it was at that time. Compasses span uselessly
and the telegraph network went down as phantom electricity surged
through the wire."
The sun had indeed been running at a record
high for the latter half of the 20th century, and has now died down to
its lowest level for a century. But Dr Clark warns that "average levels
of solar activity has fallen does not mean that the Sun is immune from
large flares or even giant ones. Low average levels of activity may even
promote the giant flares.
"Perhaps like earthquakes, when there
are constant flares/tremors the energy is dissipated evenly over long
periods of time. But in periods of quiet, that energy can build up and
then suddenly be released in a giant event. This remains speculation,
however."
if a proper "Carrington event" happens again, it has
the potential to be far more problematic now than in 1859 when electric
communication was barely in its infancy. Dr Clark says
sooner or
later we should expect there to be another Carrington event and that is
what these scientists [at NASA] are trying to prevent. Legislation in
the US has just passed Congress to help harden the grid against solar
flares."
So -- it's a real thing, and we should be concerned. But
preventive measures can be taken -- satellites can be sent offline
during big flares, power grids and communication networks can be
shielded against electromagnetic radiation and so on. As Dr Bamford
says: "The extreme events like the 1859 Carrington Event are
1-in-100-year probabilities, about the same probability as a storm of
the level of Katrina hitting New Orleans -- and New Orleans did not
build their defences to withstand the extreme-magnitude. The Katrina
catastrophy is small compared to getting hit with solar flares.
NOAA
Space W Dr Ruth Bamford, a plasma physicist at the Rutherford-Appleton
Laboratory, agrees: "The sun has been particularly quiet for the last
few years in a protracted solar minimum. It has just woken up, as it
were, and started its usual 11-year cycle a bit later than most."
