EUReferendum has followed this drama

Good forum thread too.
But bottom line is the ice arrived so quick that it caught even the experienced locals by surprize.
Roger Howard is doing us a favour, the article is linked to a book he is selling and bravo to Roger for separating Warmist fools from their money. Greens are their for our amusement. If I could get someone to write a book about 100 metre sea level rise in the next 10 years I would do so, there’s money in them there greens.
“Regional sea ice is retreating fast, threatening to raise global sea levels, ”
Frozen water in the water or unfrozen water in the water. No change in sea level.
Darn, beat me to it. Lets do a quick calculation on it though. 🙂
Recent sea ice area minimum ~ 3 million km^2
We’ll assume average thickness @ 1.5 m
Minimum volume thus equals 4.5*10^12 m^3
Ice density assumed at 916.7 kg/m^3
Water density assumed at 1029 kg/m^3 (ocean water)
So 89.1% of the sea ice is below the water surface…
Thus, minimum volume above surface = 4.91*10^11 m3
Minimum volume below surface = 4.01*10^12 m3
Above surface melt would add 4.38*10^11 m3 of water to the oceans
Below surface melt would subtract 4.38*10^11 m3 of volume from the oceans
Net change in volume = 0
Somehow I don’t think Archimedes would be surprised…
That’s if all the summertime ice melted…

This winter ice breakers operating in the Finnish Golf have found ice with a thickness of 15 meters.
The Russian ice breakers mentioned ice thickness of 18 meters and in one of the articles at Dr. Richard North’s site it was mentioned that the Tartar Street was frozen solid from the surface to the bottom of the ocean.
A Finnish ship yard STX showed a new design ice breaker for operations in the Arctic Ocean capable of breaking ice sheets of 20 meters.
This 20.000 hp ship has a specially designed hull that allows the entire ship to glide on top of the ice with only the propellors in the water.
The ice will break under the weight of the ship.
Anyhow that were the specification for this ship.
Isn’t it incredible?
But it is all rotten ice.
Isn’t it incredible?
Yes it is! I don’t know where you are getting you numbers from but this site shows less than half a meter in Gulf of Finland:

Ice only gets to a certain thickness and then it reaches thermodynamic equilibrium thickness.
“Remember that ice grows because of a transfer of heat from the relatively warm ocean to the cold air above. Also remember that ice insulates the ocean from the atmosphere and inhibits this heat transfer. The amount of insulation depends on the thickness of the ice; thicker ice allows less heat transfer. If the ice becomes thick enough that no heat from the ocean can be conducted through the ice, then ice stops growing. This is called the thermodynamic equilibrium thickness. It may take several years of growth and melt for ice to reach the equilibrium thickness. In the Arctic, the thermodynamic equilibrium thickness of sea ice is approximately 3 meters (9 feet). However, dynamics can yield sea ice thicknesses of 10 meters (30 feet) or more. Equilibrium thickness of sea ice is much lower in Antarctica, typically ranging from 1 to 2 m (3 to 6 feet).”

I’ve seen lake ice 15 feet thick, but I never seen sea ice any near that thick, except where it gets pushed up near shores.
“A source in Russia’s Federal Fisheries Agency told Itar-Tass, the two icebreakers escorting the Bereg Nadezhdy ship have covered 25 nautical miles in the past 24 hours but the distance ahead has turned out to be longer than initially planned. “The ice has hit the bottom and the ice field is spreading northwards. ”

Plenty of ice there ES.
Not much ice on the Canadian side compared to usual, so the Arctic total is low

That of course is ignored on this blog until the time it ever becomes more than normal, at which time it will become important again.

Kinda of how the Southern Hemisphere record ice extent is ignored by AGW proponents?
The Okhotsk Sea was supposed to be one of the ice free areas under AGW.
Must be a sign of global cooling.
