George,
When Carl Sagan and Edward Teller agree on something, it makes it hard to argue wiht it. They differ only in the amount of cooling not that it would occur. Meteorological models like any in the observationsal sciences contain many
assup
mptions, something experimental scientist often lose patience with. as much of
this discussion illustrates. The relative magnitude of various effects ists
oftenhard to esitimate.
Please excuse the typos but this system is fighting me again.
