but the real
problem is not the ice melting, but the water expanding as it warms up. We
warm the massive amounts of water on the planet up a few degrees, and it
expands enough to raise the sea level to very bad levels. Considering the
deep sea oceans are 12 + km deep in most places,

Where ? I thought mainly 3 km for deep ocean.

Most deep ocean is more like 5 km deep.

So when I said in my other post 2.4 meter sea level rise from thermal
expansion being on the alarmist side, take that down to 1 meter to correct
from 12 km to 5 km average ocean depth.

*AVERAGE 5km* ? Are you barking mad ?

I was correcting a calculation I improved upon without considering as
erroneous a depth of 12 km. Most ocean outside the continental shelves is
about 5 km deep, so I used 5 km as a correction over 12 km.

Take a bit off for continental shelves... I do not consider 5 vs 3.711
km ocean depth "barking mad" when proposing that a few degrees rise of
temperature of this is only good for raising sea level by a meter.

Certainly not as "barking mad" as not considering Greenland's icecap to
be arctic ice.

" The area of the World Ocean is 361 million square kilometers (139 million sq mi),
its volume is over 1,340 million cubic kilometers (319 million cu mi), and its
average depth is 3,711 meters "

Have you never heard on things such as the Continental Shelf ?

And to think I gave up geography because I didn't do that well at it !
