WASHINGTON (AP) - More than 2 trillion tons of land ice in
Greenland, Antarctica and Alaska have melted since 2003,
according to new NASA satellite data that show the latest signs
of what scientists say is global warming.

_Some_ scientists say this...

And it's funny, my workplace is right beside the Potomac River,
which is navigable all the way to the sea, and I don't seem to
need high-top boots to get in the door. Place is still dry?
Sooo... geee... where's this big ocean rise, eh?

And some people read the whole thing before foolishness:

Melting of land ice, unlike sea ice, increases sea levels very
slightly. In the 1990s, Greenland didn't add to world sea level
rise; now that island is adding about half a millimeter of sea
level rise a year, NASA ice scientist Jay Zwally said in a
telephone interview from the conference.

I do believe that this is wrong... The melting of SEA ice would have
very little effect on levels... The melting of land ice would
affect sea levels.... Of course, most of the land ice comes
from the sea in the first place....

You're right. Ice displaces as much as water does, so when it melts
there's no change in the sea level, just as there's no change when
the ice melts in your cocktail. It's land ice that's the threat,
which is why so much attention is being paid to Greenland and
Antarctica. Land ice is from precipitation, not from the sea.

look like that any more.
