Sea Ice Cometh to Hudson Bay: Freeze-Up has Begun

From Polar Bear Science

Dr. Susan Crockford

Although it may take until the end of the month for all Western and Southern Hudson Bay bears (except for pregnant females) to have returned to the ice, freeze-up has finally begun in earnest and today some bears are already heading out to resume feeding before winter sets in. This is 3.5 weeks later than last year when WH bears were first spotted have killed a seal on 31 October.

Compared to two days ago, there is now abundant ice along the western shore of Hudson Bay, both in the north and the south:

The ice near shore is heavily buckled by tides and wind, making it thicker than it would be otherwise, courtesy the Explore.org live cam:

Here’s another view of the ice with two bears on it (taken from quite a distance, hence the blurry photo):

How many months of the year do the bears feed and how many do they rely on their stored fat? Is it that once the Bay and other waters freeze up the bears start fasting, much like other bears that den up in winter and hibernate?

Was so worried since polar bears are unable to adapt to different scenarios. The survive for another season !
Seriously ….that is a lot of ice to form in 48 hours!

It really doesn’t form that fast, what happens is that slush starts to form over a large area and a change in wind direction makes it accumulate / compact along a shoreline. In Lakes Michigan and Superior you can actually go from dispersed floating slush to 3-4 foot ice bergs over night when the conditions are right.

“Staff at a pub cut off by snow held a karaoke evening last night as guests were unable to escape for a third night. On Friday, 61 people became trapped in the Tan Hill Inn in the Yorkshire Dales as a result of heavy snowfall during Storm Arwen, but some claimed they “don’t want to leave” after enjoying the 17th-century hotel’s hospitality.”

They predicted oceanic heat content would increase. It did.

Don’t hear what I didn’t say. I didn’t say their predictions are perfect. They aren’t and never will be. I also didn’t say that all of their predictions are right. They aren’t and never will be. But to say that not one prediction was correct is patently false.

What a dumb thing to say. Ice declining, temperature rising, sea level rising, heat content rising….these things were already happening (i.e., ongoing) when they made those predictions. That makes them observations, not predictions. Furthermore, since weather is cyclic, ANYTHING they ‘predict’ has the potential of being right 50 percent of the time.

They predicted that these trends would continue to happen then. The point is that it is easy to find predictions that are right which makes the statement “They cannot point to one single correct prediction.” false. Now I suspect this was just an off-the-cuff the statement made in manner akin to lashing out that the OP doesn’t really believe. And contrast the IPCC predictions with those from contrarians which predicted the opposite would happen that the trends would reverse. Those predictions were so astonishingly bad that they couldn’t even get the future direction of the changes right even though the past changes had been underway for decades. Would you find it acceptable if I had said not one single contrarian prediction is right?

The IPCC did not say we have 12 years to avoid “thermal doom” or “armageddon”. Here is what they actually said.

https://www.ipcc.ch/site/assets/uploads/sites/2/2019/05/SR15_SPM_version_report_LR.pdf

A.1. Human activities are estimated to have caused approximately 1.0°C of global warming5 above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate. (high confidence)

and

D.1. Estimates of the global emissions outcome of current nationally stated mitigation ambitions as submitted under the Paris Agreement would lead to global greenhouse gas emissions18 in 2030 of 52–58 GtCO2eq yr−1 (medium confidence). Pathways reflecting these ambitions would not limit global warming to 1.5°C, even if supplemented by very challenging increases in the scale and ambition of emissions reductions after 2030 (high confidence). Avoiding overshoot and reliance on future large-scale deployment of carbon dioxide removal (CDR) can only be achieved if global CO2 emissions start to decline well before 2030 (high confidence).

I predict the Sun will rise in the east and set in the west.

I predict the presence temperatures will continue to be less than 100 F in Texas over the next two months.

See how easy it is to make predictions on things already known to be happening?

In order for a theory to be USEFUL, it must make a prediction that isn’t already happening so that the prediction can be validated. AGW has predicted…Arctic Ice gone by 2012, and 1025, and etc. Our children will never know snow. Seas will rise by 20 meters within 100 years (now only 80 years away). Food production will fail. The Antarctic ice will melt. Greenland ice will melt. Etc. etc.

It must not be that easy because contrarians keep predicting the opposite of what is actually happening. The climate is cyclical on decadal timescales and we should expect reversal of trends frequently they say.

Can you point me to the location in any of the IPCC literature where they predicted “Arctic ice gone by 2012” and “Seas will rise by 20 meters within 100 years”? I’d like to review those materials if you don’t mind.

Sea ice was not declining prior to industrialization. In fact, many sea ice reconstructions show Arctic sea ice peaking in the 1960’s or 1970’s. Remember, that is one the contrarian talking points. That is the satellite era tracking coincides with the peak of extents and that what we are witnessing is but a cyclical decline that should have already reversed. The easy prediction, so say contrarians, is for a reversal and the bold prediction is for status quo with. Climate scientists made the bold prediction which is consistent with observations.

Of course the global mean temperature has been warmer in the past. That’s what all the evidence says. It’s just been a really long time since that happened. The last time it was warmer on a global scale was possibly during the Holocene Climate Optimum about 6500 years ago and with more confidence we can say the last interglacial period about 125,000 years ago. Don’t hear what I didn’t say. I didn’t say the MWP didn’t happen. It did and probably due to the Atlantic Meridional Overturning Circulation transporting heat from the tropics to the North Atlantic region. But the abundance of evidence says that the elevated temperatures during this era were primarily focused on the North Atlantic region.

Wadhams, Gore, et al predicted it would be ice free by the end of the last decade. The ice is still there. Predictions busted. Can you tell us when it will all disappear?

It’s warmed up. It has been warming since the end of the 19th century (way before anthro CO2 was allegedly controlling the temperature). What’s your point?

Sea levels have risen. They have been rising steadily for a long time at a completely boring rate of roughly 3mm/annum. What’s the panic for?

As for ocean heat content, take a trip to the Atlantic coast, wade into the water and try and stay there for an hour. Once you’ve recovered from the hypothermia (if you haven’t died) you can stop panicking about the miniscule increase in ocean hear content. You need to get some sense of proportion in your life.

We’ve had fifty years of busted predictions. Would you keep seeing a doctor who’d been making incorrect diagnoses for half a century?

Wadhams’s official prediction from 2012 which he submitted for publication was before 2042. Why he then told The Guardian 2016 is bizarre. You’ll have to ask Wadham’s for an explanation of that.

Gore made his predictions based on a misrepresentation of Maslowski’s work. Furthermore, Gore never submitted his prediction for publication in a peer reviewed journal. You’ll have to ask Gore for explanation of what happened there.

Neither of these sub 2020 predictions were considered by the IPCC because neither have any merit.

Andrew Wilkins said: “Read those busted predictions and weep for your CAGW cult.”

And the word “catastrophic” is only used a few times none of which are in the context of AGW. Do you want to take a crack at putting a level of warming on that? Is it 10C per 2xCO2, 8C per 2xCO2, or something else?

Actually you are confused.
lets look at each of the failed claims in more detail

They predicted Arctic sea ice AREA and MASS would decline to a point where there was NO LONGER SUMMER ICE:
100% Fail. We all knew the extents at the beginning of the Satellite era were high due to the cyclical nature of Arctic sea ice and very cold 60-70s

They predicted the global mean (AVERAGE) temperature would increase. There is NO SUCH THING as Global Mean Temperature. Its an idiotic concept. Land vs. Air vs. Water cannot be averaged and they are are poorly measured. On earth the temp ranges between -85C and +70C . Making up a number that has no real scientific value is stupid. And to support that claim the Temp records were manipulated. FAIL>>>

They predicted sea levels would rise.- Really? Where exactly did it RISE? In some locations the Sea has been Rising for all of modern records starting in late 1800s at about 1 foot per century. Many locations exhibit Sea Level decline. FAIL

They predicted oceanic heat content would increase. FAIL – It is unscientific to make this claim. 1850 to early 1900 a few sailors tossed buckets over the side and measured temps of surface water. Then we started using Ship intake from below surface and inline measurements. now we use specialized bouys that dive down to depths never measured consistently until recent 20 years ARGO … This is yet another spurious unscientific moronic claim.

2050 is their earliest prediction. The IPCC has a history of being too conservative with Arctic sea ice decline predictions as it is. For example, in 2001 they predicted that the annual mean extent would not drop below 10.5e6 km^2 until 2040. It first happened in 2007 and 7 more times after that including the last 5 years in a row. And even if 2021 ends strong with extents well above average for December (unlikely) we’ll still end the year below 10.5e6 km^2 extending the streak to 6 years in a row.

I repudiate anyone that makes baseless predictions even if they end up being true by accident. This includes predictions of 20m sea level rise by 2100, an ice free Arctic summer prior to 2020, that children won’t know what snow is within a few years, and countless other ridiculous predictions that the IPCC has never made.

I’ll even repudiate the IPCC when they make mistakes like when they predicted Himalayan glaciers would be gone 2035. Even though this was a typo (the actual prediction was said to be 2350), I’m cutting them no slack because even that 2350 prediction could not be vetted to the standards the IPCC expects. I’ll give them praise for fixing the mistake though just like I’ll give praise to anyone who admits their prediction was wrong and recalibrates their position on the matter.

The accepted scientific terms for Arctic sea ice tracking are extent, area, and volume with the units being km2, km2, and km3 respectively. That’s what I use.

oh the horror!! A brief period of no sea ice above 70N where no one lives.

It doesn’t sound horrifying or even scary to me. That’s pretty subjective though so to each his own I guess.

So, nothing to worry about. Glad you agree with all us sceptics. You better not let your fellow CAGW cult members hear you admit you agree with us – you’ll get cancelled.

Maslowski and Wadhams (two “experts”) predicted a seasonally ice-free Arctic before 2020.

Don’t forget Al Gore. I think his date was 2013.

Here are the peer reviewed works concerning the Masklowski prediction and the Wadham’s prediction.

Note that Maslowski did not predict an Arctic ice free summer prior to 2020. The 2016 figure in the publication above comes from a model which Maslowski criticizes for its simplicity. He states that “The above overview of model predictions (i.e., produced by GCM scenario simulations) and projections (i.e., resulting from the synthesis of GCM output with observations of sea ice) of a nearly ice-free Arctic Ocean and their limitations leads to an important conclusion. It suggests a great need for improved understanding and model representation of physical processes and interactions specific to polar regions that currently might not be fully accounted for or are missing in GCMs. The remaining sections of this review are primarily focused on addressing those issues.” He then goes into detail on present modeling limitations and biases and then presents the RASM model which he hopes will produce more realistic Arctic sea ice decline simulations. No actual prediction was given by Maslowski in this publication. Al Gore and the media took Maslowski’s work out of context.

And you can see from the Wadham publication that his official prediction is as stated in 2012: “The trend towards smaller areas in summer, which reached a temporary peak in 2007, will resume, and will lead to an ice-free summer Arctic in less than 30 years.” but did tell The Guardian in the same year “This collapse, I predicted would occur in 2015-16 at which time the summer Arctic (August to September) would become ice-free. The final collapse towards that state is now happening and will probably be complete by those dates.” This is really unprofessional of him. He says one thing in a peer reviewed publication and something significantly different in a newspaper interview. His 2042 prediction would have already been among the most aggressive in the scientific community, but 2016 is laughably stupid and not supported by the evidence even the evidence he himself provides in a peer reviewed paper. He definitely has egg on his face for that debacle.

Get out of town. They predicted back in 2005 that the Arctic would be ice free by 2015. We don’t have short memories around here.

Partly depends on what part of the Arctic that the summer ice was pushed into I suppose

Is there a relationship between where ice forms and La Nino/La Nina cycles?

It is likely that La Niña is influencing this situation. But mostly the stratospheric circulation and the eastern QBO.comment image

The ozone appears to be creating the bulge southward in the jet stream. Is this being driven by magnetic forces, or the mass, or both?

Meanwhile, it looks like most of the U.S. will have mild temperatures as the jet stream is north of most of us. As long as you are south of the jet stream, you will have mild weather.

Waiting for the next dip in the jet stream to come our way. It’s coming, you can be sure of that.

It looks like the jet stream has opened the door to cold weather in the UK.

Tom, as you can see, ozone causes a bulge in the tropopause.

The role of ozone concentrations in the stratosphere is to modulate the circulation pattern of the polar vortex.

Rhs,
The polar bears probably prefer the higher fat content of seals, much the same as Great White Sharks do! Both being apex predators, they eat whatever they want, when they want; but the results are still out on vegans!

Does this correlate to anything regarding weather or climate? It was getting colder in the 70’s and started warming late 70’s and early 80’s as I remember.

Ireneusz Palmowski

Most galactic radiation (at lower energies) is directed by the Earth’s magnetic field toward the poles, in accordance with the geomagnetic cutoff. Therefore, ionization of the stratosphere by the GCR is high in regions of weaker magnetic field in high latitudes. Increased air ionization in these regions must lead to local temperature increases. It is very likely that the GCR can produce not only 14C but also ozone in the stratosphere due to oxygen ionization. Temperature increases in the 50-80 degree latitude band slow down and disrupt the polar vortex.comment image

It was getting colder from 1950 to 1980 because the negative aerosol forcing was more than the positive GHG forcing. It began warming again around 1980 because pollution mitigation was underway and reduced the aerosol forcing to near and even slightly positive.

Has anyone ever done a study about weather polar bears suffer from the winter cold they live in? Does anyone know why polar bears don’t migrate south in winter, other than lack of food? If one were to put bear-sized dog houses out near the shore of Hudson bay, would the polar bears occupy them to stay warm and have cubs? Has anyone ever embedded an RF-transmitting thermometer (without mercury) in some meat and fed it to polar bears in winter to see if they are able to maintain a healthy if not comfortable internal temperature? Do healthy polar bears ever die of hypothermia during the winter? Why do most polar bears die? It seems a hellish life straight from Dante’s 8th plane.
