Something else...the hand of man. It is real, and quantifiable. Using
sound scientific techniques, we know that there hasn't been anywhere
near the magnitude of global warming, for a given time period as what
is happening now. Polar ice melt, rising sea levels, rising sea temps,
etc.

How much is man to blame?

An awful lot.

10k years ago was a
mini ice age, what did man do to cause it?

Not much. But, alas, you are comparing apples and oranges.

1860 or there abouts 20 miles of
glacier in Glacier Bay meltet.

It broke off, and to wit, hasn't come back, because of global warming.

What caused this
warming?

Warming didn't cause the break off, but global warming did contribute
to the inability of glaciers to maintain mass.

Mt. St. Helens spewed more ozone killing chemicals in one eruption
than man put up in 10-20 years.

that is pure horse****. What amount of CFC's, the leading cause of
ozone depletion was spewed by Mt. St. Helen? NONE.

The same "Enviromentalists" were saying
global cooling in 1970. When that grant money dried up, they are now
touting man caused global warming. Maybe it is grant money that causes the
problems. Does not seem to bring solutions.

Horse****.

Which part of human life is
causing the decrease in the earth's magnetic field?

Who said ANY part of human life was or was not causing the decrease?
Stick to the subject.
