Could the picture "simply" show aircraft contrails, rather than chemtrails?
There has been an enormous growth in commercial air traffic after all. Consider this quote please:
"In the past 5 years, air traffic has increased by 27 percent to 655 million commercial passengers annually. And, the number of passengers is
expected to exceed 1 billion annually by 2010."

So, it really shouldn't be too surprising that a satellite photograph would show such a lot of contrails?
Just my £0.02...
