“allowing ships to cross the Arctic Ocean”

“The North Pole will turn into an open sea during summer within a decade, according to a team of explorers who trekked through the Arctic for three months

Their findings show that most of the ice in the region is first-year ice around 6 feet deep and will melt next summer.”

Explorers: North Pole summers ice free in 10 years – The Mercury News

“The Arctic will be largely ice-free during the summer within a decade, according to new evidence collected by Pen Hadow and his team.

By Louise Gray and Louisegray 15 October 2009 • 7:00am

Pen Hadow took more than 1,500 measurements of sea ice

The average thickness of ice floes was 1.8 metres

An analysis by Cambridge University has concluded that the Arctic is now melting at such a rate that it will be largely ice free within ten years, allowing ships to cross the Arctic Ocean.

Further analysis by the World Wildlife Fund (WWF) warned that the “irreversible trend” will cause dangerous feedback because water absorbs more heat from the sun than ice, therefore further speeding up the global warming process”

Arctic will be ice-free in a decade, according to Pen Hadow

Here is the same story from 1958

“Some scientists estimate that the polar ice pack is 40 per cent thinner and 12 per cent less in area than it was a half-century ago, and that even within the lifetime of our children the Arctic Ocean may open, enabling ships to sail over the North Pole,”

Although the idea that a solid ice sheet covers the central Arctic has lingered stubbornly in the popular fancy, the northern cap of ice worn by our planet is actually a thin crust on the whole, only about seven feet thick—over an ocean two miles deep in places.”

There has been no trend in Arctic sea ice over the past seventeen years, and the ice is still about two meters thick.

    The DMI algorythm if taken back to 2009 would probably show the same thing. Eveytime the artic ice sheet begins to approach their average the area from 1981-2010 it suddenly drops or flattens despite the temperature. https://ocean.dmi.dk/arctic/icecover.uk.php

    Still waiting for Norwegian Cruise Lines to refund depo$it put down for a trans Artic Ocean cruise. Was really looking forward to seeing Northern Lights in the sky and phosphorescent plankton in the water. Sea turtles, sea cows, and penguins, too;-}

    Instead of a refund, NCL offered a cruise thru the Tropic of Cancer;-}

    Oh well.

    The interesting thing is that the 40 % less and 12 % thinner arctic ice
    happened during the 40years of a cooling trend experts used in the 70ies to push the ice age scare.
    And this leads to the question : Why was sea ice extent so much bigger during a warmer period and why did it start to shrink during cooling ?

    This is just like stock gurus saying that the market will always go up. I am numerically almost equal to where I was when Biden took over, but given inflation, I’m down what? 20%, 40%? Trends tend to be cyclic, with minor drifting long haul.
