You have to be careful discussing the factors involving this year’s ice-melt up at the Pole, for at times 90% of what is discussed has nothing to do with Sea-ice.
In my view all the furor and hoop-la spoils the serenity of watching the ice melt, so I do my best to avoid it. Unfortunately nothing makes people more irate then speaking these two words, “Calm down.” (If you don’t believe me, try using them on your wife or husband…but strap on a helmet first.)
In actual fact things do grow more calm to the north this time of year, which is why, (as we remember heroes on this Memorial Day), we remember D-day was planned for June 5, 1944. The North Atlantic was suppose to be at its least stormy in June. But, as is often the case with the weather, things did not proceed as forecast, and a storm hit. One of the reasons D-day succeeded was because the Germans didn’t think the Allies would invade in a storm, but the Allies only delayed until June 6.
It is perhaps foolish to predict anything, especially anything involving the vast, silly storm called “Global Warming”, but I have done it. I predicted furor and hoop-la, and that part of my forecast has been 100% correct. The rest of my forecast is as follows:
The ice-melt will get off to a fast start, but slow as the summer proceeds, and in the end the minimum ice-extent will be about what it was last year. I base my guess on the following:
1.) During the winter the ice was very active, and sea-ice was compressed towards the center of the Arctic Sea. Also there was less cross-polar-flow, with less ice exported from the Siberian side to the Canadian side, so the ice is thicker towards Siberia. This suggests that, when the ice-edge melts back to these areas of thicker ice, the retreat of the ice-edge will slow.
2.) The fact the sea-ice was active involved the opening of many leads in the Beaufort Sea. The exposure of the water to cold winter winds likely chilled the water under the ice, and disturbed the stratification of seawater into various levels, with warmer but more saline waters less able to sneak under the ice northwards. Therefore I assume the water under the ice is colder.
3.) The waters south of Bering Strait were two degrees colder than 2015 throughout much of the winter, which suggests any water sneaking north through the strait would be colder, (and therefore less able to melt ice from beneath), than last year’s (very effective) waters.
4.) The export of ice south through Fram Strait was fitful, and at times even reversed, during the winter, which resulted in more sea-ice being left behind up at the Pole. As this export slows in the gentler winds of summer, more and thicker ice will be left behind, slowing the melt on the Atlantic side.
5.) The melt will begin rapidly, not due to the actual melting of ice, but because polynyas formed where the ice was pushed away from shore. This off-shore wind exposes water to cooling, but also results in up-welling of slightly warmer water by the shore.
6.) Even where up-welling doesn’t occur, huge arctic rivers pour snow-melt-floods north into the Arctic Sea, and, even though this water is ice-water, it is warmer (32F) than the ocean’s ice-water (29F), and it is also less saline until it mixes with the sea. This creates a “lens” of milder water along the coasts, speeding the ice-melt. As this “lens” pushes out to sea it becomes more mixed, and loses its effectiveness, in terms of melting.
7.) As the summer proceeds the warming effect of the El Nino will start to fade, and the effect of the “Quiet Sun” will become more apparent.
There you have it. I have already been told, “Caleb, you ignorant slut”, for making my forecast, so no one needs to say that again. In any case, I won’t know if I am right, wrong, or (most likely) partially correct, until August. Therefore I am simply going to stay calm, and sit back, and enjoy the show.
I had a tap on my shoulder and was reminded what really matters on Friday evening. My wife’s brother was in a bad accident during the last snow of April, when a car came sliding across the road and crushed in his car’s driver’s side door. After an insurance hassle and physical therapy he got things back together, and was driving his brand new truck on Friday when a car came across the center line, smashed the vehicle in front of him, and managed to flip and once again crushed in the driver’s side door of the vehicle he drove.
There was about a three hour delay between the time the wonders of the internet produced the above picture and the time I heard from the hospital that my brother-in-law was bruised, royally pissed off, but otherwise OK. Three hours is long enough to contemplate how much sea-ice really matters, in the scheme of things.
Not one hell of a lot. I wouldn’t even know it was there, if it weren’t for satellites, the internet, and fools who think it matters more than the practical details of ordinary life for ordinary people.
Generations upon generations have lived their lives without a clue about what was occurring in the arctic, with the ice coming and going. It didn’t matter that sea-ice was at times nearly absent at the Pole, and at other times sea-ice grounded icebergs on the coast of Ireland, unless you lived on the coast of Ireland, or were a whaler seeking rich hunting grounds.
In some cases those whalers were hunting up in waters that people now completely freak out about, when they are open water rather than ice-covered. The history is available for those who bother to look. The whalers were glad the arctic was more ice-free on summers when the ice allowed them to sneak north. They didn’t freak out about open water in the mid 1800’s, so I want to tell people who freak out now, “Calm down”, but, like I said earlier, that doesn’t work. It especially doesn’t work when billions upon billions of dollars are involved, as people attempt to control the weather with hocus-pocus (when a Hopi priest could likely do a dance that would be more effective, far more cheaply).
The people most prone to hysteria are those who’s entire livelihood is based on the hysteria; ranging from honest professors to dishonest professors, from honestly ignorant idealists to snake-oil salesmen, from honest politicians representing deluded constituents to corrupt politicians lusting for power and gold. The world has gone bonkers, and has forgotten common sense even to the degree where people can’t agree girl’s bathrooms are for girls, and what really matters gets ignored, until you get a tap on your shoulder. Then you remember. And then it seems most sad we are spending billions upon billions on dust in the wind.
In any case, there is little I can do but take my own advice and “Calm down”. I can point out that the current uproar about the polynya northeast of Alaska is about a situation we have seen before.
I will likely be then told, “Caleb, you ignorant slut, it is much worse this year”.
The above link takes you to a really a cool site, for it lets you slide about the arctic and zoom in and zoom out, noticing things Alarmists don’t mention, such as a bit more ice in the west of Bering Strait this year, and that it was more green inland in Alaska, last year, but it is not worth arguing that there is more ice north of the Mackenzie River delta this year, for there isn’t. And considering you are given the link to focus on that specific thing, it is impolite to focus elsewhere. And it is especially rude to tell a kind person who gives you a link that they are an ignorant slut. Therefore I usually avoid that.
As a general rule I find Alarmist put me in the shoes of defending the indefensible, but find it is best to traipse lightly by that trap, enjoying the wonder of a new spring with unique weather. Nothing irks Alarmists more than embracing the very thing they think will devastate you, and instead rhapsodizing about how wonderful it is.
And it indeed is a genuine wonder how smashed up the Beaufort Sea is, after all the winter storms. I think the El Nino created a very meridienal flow, and its lagging after-effects are keeping the temperatures merely normal, rather than giving us the below-normal cold waves we saw up in the Beaufort Sea last May and early June, (that, with a sheer guess, I think were due to the “Quiet Sun”.)
To compare two years with different weather patterns is a bit like comparing apples with oranges, but pointing out last year had ice increasing when it usually melts makes this year look less alarming, when you compare a 2015 map with a 2016 map.
Then I expect to hear, “Caleb, you ignorant slut, can’t you see how warm the water is north of the Mackenzie Delta?”
I like to nod and enthusiastically agree. It is really wonderful! Alaska had a mild winter (even as Mongolia had record cold) so the Mackenzie River is pouring out a nice freshwater lens. Also the off-shore winds that created the polynya also created up-welling. How cool! There may even be some sunshine slightly warming the water, though the sun has been dim the past week.
At this point I scratch my jaw and say, “Odd”. Then I wait, until asked, “What? What’s odd?” Then I shrug and say, “Oh, I just noticed the NRL map above shows -1°C where Obuoy 14 is located, but the buoy itself is reporting -5°C. I suppose the buoy is reporting the air, and NRL is reporting the water under the ice. But…odd…”
“What? What’s odd?”
“Oh, it’s just that the picture shows the Mass Balance Buoy at that location is trashed. I just wonder how anyone knows what the temperature of the water under the ice is? It’s such a pity the buoys were so poorly placed and badly maintained, because they are so handy to have, when it comes to double-checking satellite data. But maybe they’ll rehire that guy they had last year, who was so good at recontacting buoys that went periods of time without signalling. It would be nice if we could get O-bouys 8b, 13 and 15 back, as well as Mass Balance Buoys 2015G, 2015I, and 2015J. Oh well, at least we have Mass Balance Buoy 2015F, reporting -4.31° C. But…odd…
“What? What’s odd?”
“Well, its just that it seems cold over the ice…
…and high pressure seems to be blowing that cold air right towards the Mackenzie Delta…
…And…well…you’re so concerned that the less-cold water north of the Delta might melt the ice, but wouldn’t those cold winds cool that water? ”
“Caleb, you ignorant slut.”
