Hi Dave,

The more I read the more concerned I become. I was viewing NASA's TV  network
and they had films of the arctic sea over 3 decades. It is visibly clear
that the polar cap has been shrinking.

Unfortunately the time snap shot is short which makes it easy to say  it
might be part of a natural cycle and that it has done so  before. Still, if it
melts, the ice which, it is argued, acts as  solar reflector, will become a sea
which will absorb more sunlight.

Another point that has some scientists more concerned than global  warming is
ocean acidification due to CO2 absorption. Seems we might  be headed for a
double wammy. Meanwhile it appears to be business as usual.

Best,
Joe
