Arctic sea ice melt may have turned the corner this season – with no new record low

This was the news from NSIDC on Sept 5th, 2017:

Average sea ice extent for August 2017 ended up third lowest in the satellite record. Ice loss rates through August were variable, but slower overall than in recent years. Extensive areas of low concentration ice cover (40 to 70 percent) are still present across much of the Eurasian side of the Arctic Ocean.

Arctic sea ice extent for August 2017 averaged 5.51 million square kilometers (2.13 million square miles), the third lowest August in the 1979 to 2017 satellite record. This was 1.77 million square kilometers (683,000 square miles) below the 1981 to 2010 average, and 800,000 square kilometers (309,000 square miles) above the record low August set in 2012.

Ice retreat was most pronounced in the western Beaufort Sea. A large region in the Beaufort Sea and East Siberian Sea has low concentration sea ice (40 to 70 percent). Patches of low concentration sea ice and some open water northeast of the Taymyr Peninsula are also present.

While a record low minimum extent in the Arctic is unlikely this year, the ice edge in the Beaufort Sea is extremely far north. In parts of this region, the ice edge is farther north than at any time since the satellite record began in 1979. This highlights the pronounced regional variability in ice conditions from year to year. A couple of the models that contribute to the Sea Ice Prediction Network Sea Ice Outlooks forecasted significantly less ice in the Beaufort Sea in July this year compared to average conditions.

The graph above shows Arctic sea ice extent as of September 5, 2017, along with daily ice extent data for five previous years. 2017 is shown in blue, 2016 in green, 2015 in orange, 2014 in brown, 2013 in purple, and 2012 in dotted brown. The 1981 to 2010 median is in dark gray. The gray areas around the median line show the interquartile and interdecile ranges of the data. Credit: National Snow and Ice Data Center

Today, here is the graph showing data to Sept 14th, 2017:

Source: https://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/

According to the data (updated for Sept 15th) they helpfully provide in spreadsheet form, the 5 day average extent (current value being rightmost) for the last 8 9 days is as follows:

4.717, 4.696, 4.668, 4.649′ 4.649, 4.645, 4.636, 4.638, 4.649

The daily average for the last 8 9 days is (current value being rightmost):

4.635, 4.697, 4.641′ 4.628, 4.646, 4.611, 4.651, 4.651, 4.686

It appears as if the melt season has ended, and a turn upwards has begun. Though, variable wind and weather could still force a retreat of ice extent, it certainly seems the daily extent value has started upwards.

Here’s NSIDC’s own graph with 2 standard deviations applied, it looks like 2017 is just on the edge:

The disappearing Arctic ice meme will eventually prove to be one of the simple things undoing CAGW. Others include the pause (with La Nina coming it will emphatically be back), the lack of accelerating SLR, the absence of the modeled tropical troposphere hotspot, survival of the Great Barrier Reef and polar bears, and renewables caused blackouts in Australia and UK. Things like temperature fudging will point to the underlying scientific misconduct.

Well. 1400 miles south of the north pole in the Edmonton area, we’ve had frost for the last two nights. Clearly climate change is on its way as winter approaches, and that’s the only climate change I’m concerned about. Gawd, I hate winter.

The problem with Arctic ice cover rebounding is that it will probably motivate a re-calibration of the satellite methodology. Roy Spencer correctly predicted that the RSS satellite measurement system would be altered to show increasing temperatures.

A decade ago, we were told that the melting ice in the Arctic was unprecedented and the Arctic would be ice free by 2014 based on the trend in melting ice.
I have a unique theory on this. Over the last decade, the Arctic has been mild during the Winters vs historical averages, which is causing less ice to accumulate but recently, very chilly during the Summers vs average, which is melting much less ice. The Arctic is like a real world laboratory. In the Summer, the sun shines and warms for 6 months and dominates temperatures. Short wave radiation from the sun is more powerful than the weaker long wave radiation, that the surface of the earth emits and cools it. Greenhouse gases in the atmosphere, mostly H2O(but in the Arctic-there isn’t as much H20) so CO2 has more of an effect. C02 increasing, traps some of that weaker long wave radiation all year round but in the Winter, there is no sun to compete or offset the effects. In addition, in the Winter, we have more open waters in the Arctic(vs 20 years ago for instance), which has led to an increase in evaporation and H20, which is adding to the greenhouse effect.
So the Winters in the Arctic have been dominated by the greenhouse effect of increasing CO2 and increasing H20 and have not been as cold.
The Summers are dominated by the sun, that shines 24 hours a day, despite increased greenhouse gases(year round) that trap some of the heat because the sun’s warmth(or lack of it) is greater than the warmth held in by greenhouse gases. Arctic Summers have been cool, with less ice melt recently.
The sun, last century, and until recently had been the most active in a long time. If it was been responsible for some of the global warming of the last 100 years, it would be impossible to separate the sun’s warming from the increasing greenhouse gas warming because they were in the same direction.
https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fertilization-greening-earth
“IF” the sun is now cooling the earth, while increasing CO2 continues to warm the planet, comparing the Arctic in the Summer to the Arctic in the Winter may help us to separate the effects.
It could be that something like more low clouds during the Arctic Summer is causing a negative feedback from the increasing H2O and of course acting like an atmospheric “blanket” in the Winter.
Regardless, a trend for recent Summers to be cool and Winters mild is indisputable. The Arctic is a place where the effects of greenhouse gases are the greatest/maximized, as well as the presence of the warming sun(from all day long to none) is amplified. The recent pattern change in this important region is telling us something.

If it has been, then only three of the past ten years had higher ice, i.e. 2009, 2013 & 2014. Since 1979, Arctic sea ice has never gone five years without a new record low. Its 2012 low will remain the record indefinitely.

But it appears that the pattern for Arctic temperatures we have seen for the last several years is staring to repeat. At or below mean during the summer months and over, sometimes well over, the mean for much of the rest of the year. It appears we’re entering a La Nina and yet the pattern seems to be holding just as it has during El Nina years. Why?

“Bob boder
Ice forming”
——————————–
Yes freezing actually releases heat. And yes, though the temperature is above the mean it is still well below freezing. However that does not explain the last several years deviation from the 44 year mean shown because ice starts forming about this time of year, every year!
I am just noting that despite the obvious changes going on now globally, the pattern in the Arctic appears to be repeating and I am wondering what are the possible explanations for the fact this?

Frederik Michiels
Reply to  Bob boder
September 16, 2017 12:25 pm

actually there is more ice formation and melt. thus lower temperatures in the melt season and higher temperatures during the freezing season.
that’s just one basic, the other is that the deepest cold spots are traveling from over land towards the pole (the arctic is actually warmer then Siberia or northern Canada due to the ocean surrounding it so weather patterns play also an important role.)
like this in december 2016 a strong blocking high over Siberia made it there record cold while the same blocking high did create an inflow that followed the gulf stream, making it record warm over the Arctic.

The jagged record that exceeds trend temperatures is indicative of an open water, marine temperature environment. There is a great deal of information in this simple graphic. The trend shows lower air temperature due to ice cover insulating the atmosphere from ocean moderation in the past. We see the Arctic cyclicality in this.
Open water is heat being released and dumped to space. Lots of it! As the ocean cools (as it is now) we have a global pause until much of the excess heat is gone. When the ocean has cooled enough it begins to see greater ice expansion and summer retention. Both of these trends are self enforcing as the extent of ice affects the action of wind and waves on the ice. Once maximum ice cover is established, water temperatures under the ice where it is insulated and protected from wind, start to rise again. But globally, this is a cold phase as the Arctic ocean releases less heat to the atmosphere.
This is a major temperature regulator for the entire planet and I don’t believe it is recognized at all.

Let us assume the “average daily temperatures” (from DMI forecasts for 80 North, or other simliar actual temperature records from 75+ deg North latitude). I’ve got my doubts – The plotted fall-winter-spring temperatures have ALWAYS been higher than “average” the past 35 years, so why should we believe the displayed “average” line is correct?
Regardless. If the recent Arctic sea ice extents have been consistently all year “below average”, then in fall-winter-spring open ocean waters are losing significant amounts of heat energy (greater evaporated water masses, greater water-to-air heat losses from LW radiation, convection and conduction) than if sea ice is present. Greater heat transfer into the same air masses flowing past mean higher air temperatures, all else being the same.

“In a more recent study, there is good agreement between Arctic sea-ice trends and those simulated by control and transient integrations from the Geophysical Fluid Dynamics Laboratory (GFDL) and the Hadley Centre (see Figure 16-6). Although the Hadley Centre climate model underestimates sea-ice extent and thickness, the trends of the two models are similar. Both models predict continued decreases in sea-ice thickness and extent (Vinnikov et al., 1999), so that by 2050, sea-ice extent is reduced to about 80% of area it covered at the mid-20th century.”
You are aware, are you not, that GFDL’s models fail miserably at predicting a year in advance, let alone forty years?
Climate is cyclic, not linear, as assumed in the simple-minded extrapolations of “models”.

“Extensive areas of low concentration ice cover (40 to 70 percent) are still present across much of the Eurasian side of the Arctic Ocean.”
Totally unprdicable………..Unless your a lukewarmer:
CITATION: M.G. Wyatt, et al., “Role for Eurasian Arctic shelf sea ice in a secularly varying hemispheric climate signal during the 20th century,” (Climate Dynamics, 2013).
“The stadium wave forecasts that sea ice will recover from its recent minimum, first in the West Eurasian Arctic, followed by recovery in the Siberian Arctic,” Wyatt said. “Hence, the sea ice minimum observed in 2012, followed by an increase of sea ice in 2013, is suggestive of consistency with the timing of evolution of the stadium-wave signal.”

The arctic surface temperature does not rise much above freezing during the summer but it also tends to flatten out during winter it does not keep on falling until the sun rises again in summer. I think that the surface heats up in summer and gives kinetic energy to the atmosphere which expands but when the surface cools down in winter the atmosphere contracts and gives this kinetic energy back to the surface which gives us the symmetry shown in the graph, the temperature does not keep falling because there is an atmosphere.

Rather the temps don’t keep falling because there is liquid water near the surface. Water, even if not freshwater, tends keep temps around 273K. Seawater over +30C is rare, but so is seaice under -30C.
