Spring at the Arctic circle,west of hudsons bay and inland.

June 15-warms to above freezing for a few days.
June 17-Sun starts warming the boulders on the tundra which are black from the lichen.
June 18-heat waves from the dark rocks can be seen over the tundra
June 19-heat from rocks melts the snow and a few inch's of permafrost around them.
June20-Water from the melt has no where to go as the permafrost wont let it sink in the ground,it flows downhill.
June21-meltwater hits the lake,melts the shore ice,freeing up the ten foot thick chunk floating on the lake.
june 21-lake ice starts moving back and forth from the winds,plowing up beaches
june 22-lake ice smashed to pieces and thrown up on coastal areas.

june 23-only snow left is in the 50 foot drifts scattered around the tundra.


Sept 15-Batten down the hatch's,winter is back.

Are the Maldives under water yet ?
They're first.

Seriously, though, from what I've read in objective
reports, a speed-up in Arctic ice melt will probably
raise ocean levels by 5 mm per year...that's one
inch every five years....20 inches in a century.
Populations who can, will tend to relocate as that happens.
New Orleans isn't learning that very fast though.

A far more serious side effect would be the corollary
disruption of the Gulf Stream that warms G.Britain & Europe.
Their climate would gradually cool to the latitudinal equivalent
in Canada and Russia....again over a long period of time.
People are survivors and do adapt. Those who do not, die off.
As posted elsewhere, diminishing ocean foodstocks,
worldwide pollution and ever-resistant diseases may well
render rising ocean levels to a much lower spot on the
"peril" list.
Maybe even below nuclear war....?

Just a single degree fluctuation either way in ambient temp.s would have a noticeable affect on the climate.Same with the water which stays around plus 1 or 2 celsius.

Considering spring and the melting come very fast and only last a few days imagine if you brought spring a month earlier.Where lifecycles,growing and mating season are measured in 3 months it would be devestating.The north is so delicatly balanced that any change would be very noticable to animal and plant populations and growth.

One has to understand how bloody quickly things melt when the temp gets above zero.The meltwater cant soak into the permafrost so it flows,thats why things melt so damn fast in the arctic.That's also why it's so totally different then down south here and cant be used for comparison.

When it does melt it will be unstoppable and coastal flooding from it will be in the news in my lifetime IMO.
We will adapt like the animals up there now did,the sik sik didnt migrate there,they are the tough ones that learned to adapt and survive in the north when it went from tropical to glacial.Their allmost identical to the Richardsons ground squirrels in the south except one hibernates twice as long.

The idea is that global climate change will cause a melting of the polar ice caps, therefore causing a decrease in the ocean's salinity. Wouldn't that allow the polar oceans to freeze faster and replace the lost ice? Sounds like a system that has natural redundancies built into it.

I often wonder if the Thule people who came to the Arctic did it over an ice bridge or by boat as they were sea and ocean people,living on what came from the water mostly.The only reason there's inland Inuk is because our govt. moved them there(Gjoehaven,Baker lake)back in the bad days.

I also remember reading, sometime in the distant past a book entitled something like
"Archeological investigations in the Keewatin District of the NWT." There was some discussion as to the sites being Dene or Inuit, but they seemed to consider them Inuit. Just a thought. The sites were investigated because of reports made by P.G. Downes who canoed there in the 30's and wrote a very interesting book "Sleeping Island."

I know Lyle very well.He also volunteers in driving the caribou to a safe crossing on the Thelon when they were all drowning.

$1:

Archaeological features (structures and artifacts) were described, photographed and precisely mapped by a field crew of four people (Roy Avaala from Baker Lake and Andrew Stewart, Max Friesen and Lyle Henderson all from Ontario).

Lots of artifacts all over that country,from the Dene,Inuuit and Thule who supposedly where there 1000 years before the Innuit settled.
Dene artifacts are displayed right in the Rankin inlet airport terminal but most can be found anywhere on the land once you know where to look.

The inukshuks are everywhere as are the tent rings,most artifacts are found on the eskers as thats the only place where camping or digging was possible.

I could sit and listen to the tales for hours while up there working with the Innuit as most are pretty savvy on their heritage.
