Riots, wild markets: Did space storms drive us mad?
LONDON (Reuters) - Rollercoaster financial markets and the worst
riots Britain has seen in decades have made it quite a week for a
time of year that is usually so dead the newspapers are filled
with "silly season" tales of amusing pet antics.
Everyone is pointing fingers -- at blundering politicians, hooded
thugs, disaffected youths, bumbling police and greedy bankers --
but could the cause for all the madness really be the star at the
center of our solar system?
There isn't a lot of evidence pointing to little green men
involving themselves in Earthly affairs, but the sun has been
throwing bursts of highly charged particles into space in a
phenomenon known as coronal mass ejections or CMEs.
Three large CMEs prompted U.S. government scientists to warn of
solar storms that can cause power blackouts and the aurora
borealis, or northern lights, caused by disturbances in the
Earth's atmosphere, have been spotted as far south as England and
Colorado, NASA said.
"Earth's magnetic field is still reverberating from a CME strike
on August 5th that sparked one of the strongest geomagnetic storms
in years", website SpaceWeather said.
Some academics have claimed that such geomagnetic storms can
affect humans, altering moods and leading people into negative
behavior through effects on their biochemistry.
Some studies have found evidence that hospital admissions for
depression rise during geomagnetic storms and that incidents of
suicide increase.
A 2003 study by the Federal Reserve Bank of Atlanta found that
such storms could affect the stock market, as traders were more
likely to make pessimistic choices.
"Unusually high levels of geomagnetic activity have a negative,
statistically and economically significant effect on the following
week's stock returns for all US stock market indices," the authors
found in their report.
It could of course be mere coincidence that this has been a
rollercoaster week on the markets, and that Britain was rocked by
a wave of ferocious rioting and looting.
But market watchers may take comfort from the fact that the space
weather forecast for Friday has gone quiet again.
They shouldn't be too complacent though. The solar cycle is on an
upswing due to peak in 2013 and there are likely to be more
geomagnetic storms heading Earth's way in the months to come.
