September 28 2008
In yet another sign that the Earth could be heading in to a period of
global cooling, NASA reports that the solar wind is now at a 50-year
low, the lowest that NASA has seen.
This change in solar activity, which began to occur about a decade ago,
coincides with the end of the climb in global temperatures that had been
underway for decades.
"What we>re seeing is a long term trend, a steady decrease in pressure
that began sometime in the mid-1990s," explains Arik Posner, NASA>s
Ulysses Program Scientist in Washington DC.
"How unusual is this event?
"It>s hard to say. We>ve only been monitoring solar wind since the early
years of the Space Age-from the early 60s to the present. Over that
period of time, it>s unique. How the event stands out over centuries or
millennia, however, is anybody>s guess. We don>t have data going back
that far."
As a result of the diminished solar wind, cosmic rays are entering the
Earth>s atmosphere in greater number. Research at the Danish National
Space Institute shows that cosmic rays increase cloud cover on Earth,
and that this cloud cover can have a cooling effect.
Does this help explain why global temperatures plateaued a decade ago,
and why they are now decreasing?
Stay tuned!
