What a wonderful subject! Tree rings, air pollution,
etc.
Just a random thought here... There is evidence that
cleaning the emitions from factories actually
increases the problem of greenhouse gasses. You see,
when the heavy particulates are separated from the
gasses the gasses are more apt to rise higher and stay
aloft longer. But everybody is happy since the air is
"clear" and not smelly.
Nice to see that there is one other person (Dirk) who
is a tree-ring guy. There aren't many of us. Up in
Michigan the sand-dunes migrate and they will reveal
ancient forests buried many hundreds of years ago.
These dunes can move pretty quickly. Between
1977-1980 six houses were swallowed by the dunes
during the winters. One disappeared overnight when
the dune advanced nearly 60 feet during a storm.
The mistake scientists make when looking at geologic
events is that they apply "current rate of change" to
major earth events. For example: According to common
wisdom, the Grand Canyon took millions of years to
form. I humbly submit that this is entirely
incorrect, as the erosion pattern is not that of slow
wear, but that of a cataclismic event with the
draining of an entire sea. This could either be the
Biblical flood or it could have been a sudden rising
of the region above sea level. The evidence of lush
vegitation in the area indicates a wetter environment
which would have formed gentle hills and valleys, not
a canyon.
