| | | The worst is not while we can say "This is the worst"."
Just whan you thought it was as bad as it could get . . . .
I read recently that genetic studies of bryozoans, tiny marine rockliving animals, in the Ross and Wendell seas in the Antarctic show that the rwo populations have only been separated for at most 150,000 yrs, not several million as had been thought. This means that the ice sheet separating the two seas is far less stable than assumed. If it collapsed it would caise a rise in sea level of at least 10 metres over a period of a few months.
Just think about that figure. Bangladesh, much of Pakistan, the Pacific and Indian Ocean states, mch of the Near East including the oil states, half Australia, and rather nearer home, most of London and the SE, East Anglia, Holland, Northern France; all would be underwater.
We have invented the perfact cure for global warming. We are going to kill ourselves off. The trouble is, we'll take all the other land life with us.

You weren't perchance one of those people in the last century who were saying mankind would destroy itself in a nuclear holocaust?   |

Makes you feel like going and looking at the map to find out your elevation, I always feel happier living up a bit of a hill, not that I do now. |

I find stories like that very hard to take seriously.
If one looks at the physical size of the Ross & Weddell ice sheets, and compares it with the size of the rest of the world's open oceans, even if one subscribed to the theory, it would be difficult to see how the complete melting of those two sheets could raise ocean levels by more than a few millimetres at most.
However, since these ice sheets are already floating on the seas, their melting wouldn't actually raise the water level at all, as floating ice when melted only displaces its own "liquid" volume. (i.e. its melted volume).
The amount of ice held above water level would be negated by the amount of air trapped in the ice below water level. Hence if it all melted, no increase in water level. (For anyone that disbelieves, float some ice cubes in a glass of water, with a level mark on the side, and let them melt).
The only ice that would have any effect on ocean levels would be ice currently standing on land above high water level.
Regards,
Mike.

As a 'glass knocked over man' I prefer to go with the 'doomed' scenario!

I'm with Mike - as a doomsday scenario it's not very convincing. Huge areas of the Antarctic Ocean freeze and thaw every year but we don't see any seasonal change in world sea levels for exactly the reason that Mike explained. Floating ice displaces the same amount of water as it produces when it melts.
In addition, I think it would take years, not months, for that amount of ice to melt and while it's doing so fresh ice will be forming in its place.
So you can cancel your order for snorkels and shark repellant, you won't be catching the boat to work any time soon!
