.. The question to debate is no longer "Is the globe warming
due to human activity?" It is. Unanswered questions now
include, "How warm will it get?," "What are the ecological,
environmental, economic, and political consequences?" ...
Folks, the question is _not_ whether there _is_ "global warming"
but what is the cause?
We are coming out of one of the Earth's periodic glaciations. Of course
there is an increase in the average world temperature --- and that increase
will continue for a few more years ie centuries. This cycle has been going
on for billions of years -- in _my_ memory -- probably before that!
BUT is there any reliable evidence that the so called " greenhouse gasses"
have any appreciable effect on this warming. Yes, there is an increase in
CO2 and, yes, there is an increase in ave temp. Connection??? Physicists
are supposed to be better than what we hear here.
