Southern Ocean rise due to warming, not ice melts

Melting sea ice or "Antarctic ice shelves jutting into the ocean do not directly add to sea level rises."
The Australian scientists ought to look at the melting permafrost in the Arctic, sending the water into the oceans.

... and coming back as snow.

Sea ice is back

No no no it is because of global warming the ice is back


or it's because of La Ninia,, yeah thats it

erh we predicted it


umh umm it's because it's a leap year

The top few inches of permafrost might melt in the one month of summer they get but it comes back awfull fast.

Is that when everyone gets a chance to pull their boots outa the mud.

Don't forget, all that rising water will 'fill yer boots'

One of the reasons theres so much water and ice in the arctic is the permafrost,the water cant go through it so it just sits there.Thats also the reason the snowpack melts off the tundra within a few days,once theres enough water to start flowing the warm water cant penetrate the permafrost so heads downhill to the lake,Thats also the reason a frozen lake will melt overnight,the warm water.(+1 or +2)

Where I was at all you needed was a meter of fill on the permafrost and you could build anything as it would never see sunlight and therefore never melt or thaw.

But than some veggan couch potato in the GTA who saw a movie is more of an authority..........

cold cold everywhere cold...thick ice too

no worry for you lefties the article contains the required environmental legal disclaimer

The ice between Canada and southwestern Greenland has reached its highest level in 15 years.

Minus 30 degrees Celsius. That's how cold it's been in large parts of western Greenland where the population has been bundling up in hats and scarves. At the same time, Denmark's Meteorological Institute states that the ice between Canada and southwest Greenland right now has reached its greatest extent in 15 years.

'Satellite pictures show that the ice expansion has extended farther south this year. In fact, it's a bit past the Nuuk area. We have to go back 15 years to find ice expansion so far south. On the eastern coast it hasn't been colder than normal, but there has been a good amount of snow.'

But how do these new reports fit in with continual reports that ice in the Arctic Ocean has been melting at a record rate due to increasing temperatures? And isn't global warming at the top of the political agenda these years?

Shifting weather

If it's up to meteorologists from Denmark's Meteorological Institute, there is not anything inherently contradictory that extreme cold is replaced by higher temperatures than average. Or that melting sea ice occasionally is replaced by expanding ice sheets.

'Weather is a phenomenon which changes from year to year and right now the atmosphere has changed so we have cold weather. That will certainly mean that melting ice in the North Pole will be less this year, but next year the situation can look completely different,' according to Henriksen.

To sum things up, global warming hasn't been called off. In the meanwhile, western Greenlanders will have to accept that the cold weather continues for some time. At least until next Tuesday when milder weather could be on the way, according to Polarfronten online.

To be fair, large buildings will melt permafrost after awhile so they use tubes filled with gas to keep it frozen.When it warms up the gas rises to the surface to be cooled down again and sinks back down to keep the permafrost frozen.
The temp difference just below the tundra is usually a fraction of a degree next to 0.
The grass is an excellent insulator in spring thaw(july) and an excellent reflector of the suns warmth,I've seen where it's -15 in june and the heatwaves coming off the tundra look like something you would see in the desert.Mother natures way of balancing things out.The light yellow grasses dont insulate as good as the darker ones and those areas can melt down to 1 meter in the short summer month.

If you pull back the thin layer of grass on top of permafrost and expose black dirt there will be a pool of water there within ten minutes,thats how good of an insulator the tundra is.

Heres a really good link on permafrost and pingo's if anyone's interested,most of what I posted is just personal observations from working with that shit .
