- Dear Jeff,
- The following URL links to today's NASA Astronomy Picture
of the Day and goes into explaining the multiple 'contrails' over Georgia
and other states. It seems to be disinformation, as if they are trying
to get the public accustomed to chemtrai|s.

- Explanation: Artificial clouds made by humans may become
so common they change the Earth's climate. The long thin cloud streaks
that dominate the above satellite photograph of Georgia are contrails,
cirrus clouds created by airplanes. The exhaust of an airplane engine can
create a contrail by saturating the surrounding air with extra moisture.
The wings of a plane can similarly create contrails by dropping the temperature
and causing small ice-crystals to form. Contrails have become more than
an oddity - they may be significantly increasing the cloudiness of Earth,
reflecting sunlight back into space by day, and heat radiation back to
Earth even at night. The effect on climate is a topic of much research.
You can help NASA measure the actual abundance of contrails by participating
in a contrail counting exercise that runs over the next two days. (See
