[ RadSafe ] "State of Fear"

[John Jacobus]

Andy,
Two hundred years ago would bring one to the start of
the "industrial" age.  You will recall from your
history that is went there was a push to use more
coal, a producer of CO2 which I believe is a major
green house gas.  Maybe you have hit on the reason for
the start of the current climate change.
