In the 2004 January issue National Geographic :
"Probing the Frozen Arctic" begins on Page 100
Lovely photos/maps ....
After page 109, double page spread :
"Diminishing Sea Ice
The Arctic's largest ice shelf broke in half in 2002,
and the following year saw record low summer ice
cover for the region. Predictions vary on the
timescale of melting but few deny the trend. So
what's to come ? Some will benefit - from shortcut
sea routes, more accessible oil fields, and new
fisheries. But increased traffic and industry will
taka a toll on the oceans. And ice-dependent
people and ecosystems are in for a rough ride."
Page 117 :
Today's Arctic ice melts earlier and freezes later than in decades
past - easing ships' passage but altering a fragile ecosystem reliant
on solid seas.
Since water "finds its own level", the continuing
trend of ice melt is resulting in rising waters
globally - adding the weight of those rising waters
on coastlines is going to make them *sink* faster.
Those coastlines are going to retreat .... so -
looks like the MidWest/Mississippi "basin", the U.S.
grain "breadbasket", that used to be underwater
aeons ago, may become good fishing again.
Salt water fishing. In the "Gulf of Mexico" - from
beaches in Colorado (west) ? Wisconsin (north)?
Appalachian islands/ridges (east) ?
