Guest essay by Eric Worrall
From the “Global Warming Causes More Snow” department comes a claim that the substantially increased risk of maritime embarrassment for scientists trying to sail to the North Pole is the result of global warming.
New research documents a counterintuitive impact of global warming: sea-ice hazards to shipping
Human-caused warming is popping the frozen corks that normally bottle up thick sea ice in the Arctic Ocean, allowing it to pour south
Ships plying the North Atlantic Ocean in spring are facing increased hazards from floating Arctic sea ice as a result of human-caused global warming.
That might seem counterintuitive, but here’s what’s happening, according to a new study published in the journal Geophysical Research Letters:
Warming temperatures are causing ice that normally blocks narrow ocean passages in winter and spring to break up earlier than in the past. Like a cork removed from a champagne bottle, the early break up in these passages is allowing thick, old sea ice to flow south from the Arctic Ocean into the North Atlantic, choking areas used by fishing, shipping and ferry boats.
“Heavy ice conditions along Canada’s east coast during spring 2017 presented hazardous conditions for the maritime industry at a time of year when vessels typically do not need to contend with sea ice,” the researchers note in their paper. As warming has caused Arctic sea ice to shrink and thin overall:
… it has become increasingly mobile. This has contributed to increased ice transport through narrow channels along the periphery of the Arctic Ocean … and increased the presence of thick multiyear sea ice from the High Arctic at more southern locations that have typically not contended with such sea ice.
…
The abstract of the study;
Increasing Mobility of High Arctic Sea Ice Increases Marine Hazards Off the East Coast of Newfoundland

Heavy ice conditions along Canada’s east coast during spring 2017 presented hazardous conditions for the maritime industry and required the Canadian Coast Guard to pull its research icebreaker, CCGS Amundsen, off its scientific cruise to provide ice escort services and conduct search and rescue operations along Newfoundland’s northeast coast. Greater ice concentrations and a thicker ice pack than are typical of this area created the anomalous ice cover. Within this paper we present in situ observations of the ice cover, confirming that pieces of multiyear sea ice from the high Arctic were present within the ice cover, and subsequently examine the transport pathway that connects the export of thick multiyear sea ice from the Lincoln Sea and Canadian Arctic Archipelago to coastal communities in Newfoundland. We conclude with a discussion on how an increasingly mobile Arctic sea ice cover may increase these ice hazards in the south.

Last year WUWT reported how the CCGS Amundsen scientific expedition to monitor Arctic melting had been cancelled due to too much ice.
There is obviously only one explanation which fits the evidence. Bitterly cold Northern winter and more icebergs in the Arctic Ocean. Global Warming is here.

The quality of a paper is inversely proportional to the number of authors; in this case 16 authors all wanting to be associated with BS. That’s academia for you – how 16 people can waste the maximum amount of taxpayers’ money.
Wait a minute! You can’t possibly expect the really senior authors to wipe up the leftover S, do you?
Faith is absurd. But for a true believer, the whole world, and anything that happens in it, serves as a confirmation of his absurd faith. Because faith is a state of mind, like schizophrenia, it cannot admit any lack of knowledge, and perceives reality as a projection of disturbed inner self.
I see you have met my ex….
But reality IS a projection of (more, or less) disturbed inner self…
The fact of the projection does not change, only the degree of disturbance…
Post modernists will assure you that truth, or reality, “is a social construct”.
What they fail to understand, is that its not just that.
Any more than a landscape painting is.
Sunrise’s Swansong “https://sunriseswansong.wordpress.com/” has a March25 post with some interesting observations and graphs re ice export and causes thereof eg:-
“During the period 1815-1817 so much ice came south it was described as “convulsions” by whaling ship captains, who noted sea-ice far to the south, off Ireland, even as there were open waters north of Greenland.”
So many people to write a pathetically bad paper. WHY? I used to write mine on my own
Ice mobility. At my age you just love mobility.

Yet another proof of dangerous global warming !
Warmists are desperately trying to prove by any means possible that global warming is still happening. It did actually happen from 1975 to 1998 because of all the CFCs we sprayed and leaked into the atmosphere. These were then photodissociated on polar stratospheric clouds to yield monatomic chlorine, which depleted the ozone layer catalytically. That resulted in increased irradiation of Earth with ultraviolet-B radiation, which, if it could cause severe sunburn and genetic defects, could also cause warming. The Montreal Protocol put a stop to all this nonsense, but unfortunately, it’s still happening, because chlorine destroys ozone catalytically and it has a long residence time in the atmosphere. Logically enough, since the polar regions are where ozone holes develop, greater warming in the Arctic should be an expectable consequence. None of this is due to CO2, which can’t act as a greenhouse gas in Earth’s atmosphere.
CO2, is there anything it can’t do?
Maybe Canadian leaders can use the carbon tax revenue to build more icebreakers. Or maybe all of that revenue is spoken for in the budget for vote buying.
when oil hit $150 a barrel the price of gasoline hit $1.50 a liter. now with oil at $60 a barrel the price of gasoline has come down to only $1.50 a liter.
Much more of this global warming and we’re going to freeze to death….

scientists predict less ice will cause more icebergs.
taxpayer predicts scientists haven’t really got a clew and make it up as they go along.
Start with a conclusion. Work backwards and rationalize a path to get there.
The new scientific method.
Is the icebound, brand new U.S. warship out yet or was that a low priority item for Ottawa?
It will probably stay where it is until all ice has melted. Even though it could now probably get out with icebreaker assistance it would only take a single good-sized floe to ruin the sonar dome and send it back to the dockyard.
