Arctic wintertime sea ice extent is among lowest on record

Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.

On March 17, the Arctic sea ice cover peaked at 5.59 million square miles (14.48 million square kilometers), making it the second lowest maximum on record, at about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached on March 7, 2017.

More significantly from a scientific perspective, the last four years reached nearly equally low maximum extents and continued the decades-long trend of diminishing sea ice in the Arctic. This year's maximum extent was 448,000 square miles (1.16 million square kilometers)—an area larger than Texas and California combined - below the 1981 to 2010 average maximum extent.

Every year, the sea ice cover blanketing the Arctic Ocean and surrounding seas thickens and expands during the fall and winter, reaching its maximum yearly extent sometime between late February and early April. The ice then thins and shrinks during the spring and summer until it reaches its annual minimum extent in September. Arctic sea ice has been declining both during the growing and melting seasons in recent decades.

The decline of the Arctic sea ice cover has myriad effects, from changes in climate and weather patterns to impacts on the plants and animals dependent on the ice, and to the indigenous human communities that rely on them. The disappearing ice is also altering shipping routes, increasing coastal erosion and affecting ocean circulation.

"The Arctic sea ice cover continues to be in a decreasing trend and this is connected to the ongoing warming of the Arctic," said Claire Parkinson, senior climate scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's a two-way street: the warming means less ice is going to form and more ice is going to melt, but also, because there's less ice, less of the sun's incident solar radiation is reflected off, and this contributes to the warming."

The Arctic has gone through repeated warm episodes this winter, with temperatures climbing more than 40 degrees above average in some regions. The North Pole even experienced temperatures above the freezing point for a few days in February.

In mid-March, cooler temperatures and winds pushed out the edge of the sea ice pack and caused a late surge in ice growth that brought the maximum extent closer in line with the past few years.

In February, a large area of open water appeared in the sea ice cover north of Greenland, within the multiyear ice pack—the Arctic's oldest and thickest ice. Most of the opening has refrozen but the new ice is expected to be thinner and more fragile, and a new opening might appear during the melt season. This could make the ice in this region more mobile and prone to exiting the Arctic this summer through either the Fram or Nares straits, ultimately melting in the warmer waters of the Atlantic Ocean.

"This old, thicker ice is what we expect to provide stability to the Arctic sea ice system, since we expect that ice not to be as vulnerable to melting out as thinner, younger ice," said Alek Petty, a sea ice researcher at Goddard. "As ice in the Arctic becomes thinner and more mobile, it increases the likelihood for rapid ice loss in the summer."

Despite the fact that this year's melt season will begin with a low winter , this doesn't necessarily mean that we will see another record low summertime extent.

"A lot will depend on what the wind and temperature conditions will be in the spring and summer," Parkinson said.

Starting March 22, Operation IceBridge, NASA's aerial survey of polar ice, is flying over the Arctic Ocean to map the distribution and thickness of sea ice. In the fall, NASA will launch a new satellite mission, the Ice, Cloud and Land Elevation Satellite-2 (ICESat-2), which will continuously monitor how sea ice thickness is changing across the Arctic.

Well, seas not frozen means more evaporation, and thus more snow and harsher winter inland.

"Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record" Polar bears are therefore extinct.

The diminishing atmospheric carbon dioxide content

Finally some getting their slide rule and calculator out and measuring the heat capacity, during the last ice age the carbon dioxide had fallen to 0.04%, it is now at 0.03% and still falling! If we want plant and animal life to survive on the diminishing carbon content of the atmosphere (the carbon cycle) we will have to seriously consider increasing the carbon dioxide content of the atmosphere

mackita:- The question isn't if the arctic ice doesn't melt - but if it doesn't melt too fast instead for being heated just by sparse carbon dioxide within atmosphere. The atmosphere cannot heat the marine water too much, having 5.000 - 7.000-time lower heat capacity. Even if its mean temperature would increase by whole one degree of centigrade during last decade, how it could explain the nearly synchronous warming of the 300 - 700 m deep column of water beneath it? If nothing else, then some lag should be observable there.

The sun is totally responsible for keeping the earth warm

Despite popular belief the sun is totally responsible for keeping the earth warm! Without the sun the earth will be as warm as the far side of the moon, in common parlance in other words frigid -200 odd degrees centigrade.

It should be a fairly simple mathematical exercise in the total daily output the earth receives daily from the sun where the air absorbs and radiates back into space and the sea absorbs and radiates back into the atmosphere which is then radiated back into space.

The emission of the ice flows

The satellite images of the earth's poles on Google earth do not show the satellite images of the ice. I am still waiting for an explanation for this anomaly! Its emission speaks volumes, or is it a guilty conscience.

The earth's magma won't keep your toes warm if the sun was extinguished for example in iceland magma flows freely

Without the sun the earth will be as warm as the far side of the moon, in common parlance in other words frigid -200 odd degrees centigrade
mackita:- You just disproved yourself in a single sentence: the Moon is as illuminated by Sun, as the Earth - yet it remains way colder in average. But the atmosphere insulates as well the heat coming from Sun, both the geothermal heat coming from Earth itself. The people would get surprised if they would slice the Earth in half: we literally floating of brightly glowing ball of hot magma, separated from cosmic space just by thin layer of crust. I mean relatively thinner than the skin of apple with respect to the bulk of apple.

Just wow!! The complexity of the earth's climate system is challenging super computer modeling. Millions of hours of scientists, and modelers time - and they are constantly being refined - in attempts to get the model closer to reality. Mixtures of gas in the atmosphere; clouds forming and dissipating; glaciers growing and shrinking; pertrubance in the system such as storms; ocean currents; etc. etc. etc. - and you think it should be 'fairly simple'?


Mar 24, 2018
The earth's crust insulates the ball of magma, if it did not it would have gone cold billions of years ago.
The lunar surface in shadow for example in polar craters drops to below -200 centigrade, there are two main sources of heat the sun and the earth's magma , the earth's magma has not prevented a single ice age. Greenland is covered in ice despite the great big ball of plasma.
Germany like other continents were covered in ice on previous ice ages https://phys.org/...ars.html
The arctic ice is floating on water; despite the water being above freezing, the north pole retains its ice throughout the summer

Simplifying complexity

There's simplicity in the complexity, the Sun reverse its poles every 11years and the Sun pulses by expanding and contracting cyclically every 11years where its temperature varies by the activity of its sunspots. The earth wobbles on its orbit every 26,000years where the earth's orbit varies in a 400,000year cycle leading to ice ages occurring every 100,000years with mini ice ages in between, it is the solar temperature variation as little as of 1 degree over 100,000s of years and variations in the earth's orbit which lead to major and minor ice ages.
Very little down on planet earth has any significance part to play especially the insignificant 0.03% and falling CO2 has virtually no part to play, the major ocean currents and major air currents have only a small part to play

Mar 24, 2018
Trees remove carbon dioxide from the atmosphere and store carbon in their trunks

"the insignificant 0.03% and falling CO2" We have been burning fossile fuels since the industrial revolution and the new industrial revolution is turning to electrical power which does not burn fossile fuels so does not produce CO2. The plants have reduced the CO2 of several percent to its present level of 0.03% so with the continous disuse of fossile fuels the plants will continue the gradual decline of atmospheric CO2.

"the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA" is a politicized agency for advocacy of AGW and CC scare.

How comfortable are you with the source? I have seen other and multiple sources that contradict them. So how can such disparities be? Is there differences in measurement, timing, or something else. NASA and NOAA have collectively manipulated temperature data. How can we trust them here? NOAA once showed a picture of the N. Pole melting. The picture was 600 miles south of the pole. Perhaps that was where the Pole was 6 months earlier as the ice moves.

Despite popular belief the sun is totally responsible for keeping the earth warm!

If what you are saying is that sunlight is the ONLY factor determining climate temperature, that is clearly false as science pooves that other casual factors effect climate temperature as well, such as CO2 etc.
If what you are saying is that sunlight is a significant factor determining climate temperature, NO such "popular belief" exists to the contrary and there is certainly NO "popular belief" that sunlight doesn't warm the Earth.
So, either way, whatever you mean by your above assertion, it is false.

We assume FUR of Polar Bear offers protection from Cold. But, it is actually a vulnerability because Youtube Videos show that they get into water BELOW the Ice-Blocks in the Sea. It goes to show that we are NOT using wonderful features of animals around us for our bodies. There seem to be no attempts made until now to garner useful features of our fellow living organisms. It is true that gene-editing technique is only half a decade old and we CERTAINLY CANNOT mess up our bodies foolishly. But there are small lab animals that may not tolerate cold temp and We have to try to transfer the great feature of Polar Bear to such a Lab Animal !

The Sun is the only heat source where the Sun is an 800,000mile diameter nuclear furnace!

The Earth's molten core is kept active by the gravity of the Moon and the Sun. But however which way you turn, the earth is a frigid place without the Sun, put your hand on the soil it is only at atmospheric temperature of 15 degrees centigrade so not as it has been pointed out anywhere near the 3000 degrees temperature of molten larva so apart from the Sun the only other source of heat on a scale large enough is the larva coming out of volcanoes and volcanoes do not erupt in the numbers they did billions of years ago because the larva is cooling and 7 miles down on the sea bed in the Marianas trench the water is about 1 degree centigrade. So even seven miles closer to Earth's molten lava is not increasing the temperature of the water!

We are in minimum Sunspot activity just like our last mini ice age

There has been very little sunspot activity since 2005 and it has not picked up to pre 1999 levels as we are going through a cool period which takes a 100 years to proceed just like the little ice age where during the freeze there was very little sunspot activity.

Where the Sun doesn't shine, the temperature plummets

We're not talking average temperatures! We're talking about the surface temperature when the sun is not shining on the actual surface of the Moon, the temperature plummets. We can see you have obfuscation down to a fine art!

Actual temperatures are not average temperature.

TrollBane:- The statement if you care to read it "Without the Sun the earth will be as warm as the far side of the moon, in common parlance in other words frigid -200 odd degrees centigrade." Is quite clearly stating where the Sun does not shine on the far side of the Moon while it's shining on the surface opposite the Sun because as you know even the polar craters in direct sunlight casting shadows on their basins, their basins are below -200 degrees. This is a comparison to show the frigid temperature of the Earth if the Sun is not there to keep the Earth warm. For some reason TrollBane for reasons known only to yourself, TrollBane you chose to obfuscate.

Dark matter is like Dr Zeus and his three cats in his hat

mackita:- There is some thought on the fact there might be some low level nuclear reactions taking place in the Earth's core, your input to further this entirely possible scenario is just muted somewhat by bringing in the discredited darkmatter; darkmatter should only be brought out the hat when all else fails.

mackita:- I presume the phenomena responsible for low energy nuclear reactions could be culprit here, because the speed of radioactive decay both cold fusion seems to be affected by presence of dark matter and low energy neutrinos. .

Carbon dioxide does not even register on the on any sort of imaginable scale

mackita:- The molten core is responsible for geothermal springs and volcanic action on the seabed where funnels are releasing superheated water 5 miles deep maintaining a landscape of creatures and fauna, the main point the larva is maintaining a large heat input where the currants of superheated water rise, The Icelanders use their larva tubes that come to the surface by drilling down and pumping water in for hydro electric steam power. This all goes to show the large amount of heat the Earth is inputting into the sea, tundra, and through volcano's into the atmosphere. As you can see, makita; carbon dioxide does not even register on the on any sort of imaginable scale

ppm is an imaginable scale. Yes it is a small number - so what? We understand the physics of it. https://www.skept...fect.htm

So you are declaring that C02 is not causing warming - is that correct? Then what is causing warming - and where is your evidence?

Mar 25, 2018
Green housing is a heat retention process, an insulator will absorb heat to its particular capacity. If you take a mixture of molecules and within it increase or decrease the amount (ppm) of a substance whose absorption potential is known to be highly absorptive to infrared radiation you alter heat retention within that particular volume. So a volume of a gas that has a higher number of molecules with high heat absorption potential (such as our knowns: h2o co2 co etc.) in relation to its total constant volume will be warmer than one with a lower relative amount of those same highly absorptive molecules and compounds in its composition, given the heat source (eg. our Sun) remains at same intensity.

Simply put. The higher the concentration of greenhousing agents within a solution the higher it's heat retention potential. The higher the percentage of h2o and co2 and co etc. in our atmosphere the higher the temperature.

Spot on greenonions1 CO2 is not the cause of warming

Exactly greenonions1 your statement " C02 is not causing warming - is that correct" you are correct! CO2 is not causing warming, it is trace gas 20% oxygen, 79%nitrogen, 0.03%CO2.....oxygen and nitrogen have greater insulating properties due their greater quantities, and the atmosphere is not the cause of warming. It is the heat source that is the cause of warming!

There we go again with the false premise. When did I last have dinner with ET?
1. That global warming is or has occurred is conjecture. ARGUMENT IS NOT PROVIDED TO ANY STANDARD OF SCIENTIFIC CONFIDENCE! It is a fool who thinks they know everything about everything with certainty. Making the assertion that a .5 or 2 degrees C change has occurred over the past 50, 100, 500, or 2000 year intervals is to assume other variables are not at play and the manufactured data sets are good. The current assertions use temperature data sets that have been inferred by a community having a natural bias towards the desired results. Previously, it was discussed that temperature variability is a non-linear function due to the complexity of the system. See http://lorenz.mit.edu/ .

2. Chemistry and physics establishes that CO2 absorbs and re-radiates heat. Further, this can, may, possibly contribute to a greenhouse effect. CO2 is a trivial player next to H2O and even more trivial next to CH4. That CO2 can have a measurable contribution next to H20 has not been established. Repeat teasing out that CO2 has a measurable effect relative to H2O remains to be seriously addressed.

If climastrology was a legitimate science it would be massively cross disciplinary and this would be found in their papers. As with good science postulates and assertions include the elimination of other causes and error. Statistical gaming is played with climastrology papers. I have yet to see one which seriously addresses the elimination of other causes. Of course if this is wrong it would be appreciated if such could be cited.

CERN's announcement of the Higgs Boson was made after it was determined that their change of a false assertion was less than 1 in 3,500,000.

Should there be any papers which can address CO2 as something above background noise those would be nice to have the citation of.

The CO2 molecule stops insulating and becomes a conductor

There's infra red radiation, heat retention, heat capacity and insulating properties. Insulating properties do not transfer heat, they insulate against heat loss which implies they have to prevent the heat flow, by absorbing IR CO2 will heat up which means to insulate against heat loss the molecule has to retain that heat and not emit it to retain the status of a insulator and all this time it is continually absorbing IR so the molecules temperature is continually rising. If this true the CO2 molecule subjected to IR will have a temperature rise against IR and time as a point will be reached when the molecule stops insulating and becomes a conductor

Mar 25, 2018
Does this have an effect at surface temperatures or those at higher altitudes?

The Earth's molten core is kept active by the gravity of the Moon and the Sun.


Are you saying tidal friction keeps the core molten rather than U decay?

Mar 25, 2018
CO2 does not insulate it! It absorbs and emits a photon!

Well that didn't take long, the CO2 molecule has absorption rates as it absorbs an IR photon, oscillates, remits the IR photon and ceases oscillating where the emitted photon is absorbed by a neighbouring CO2 molecule. So that is the extent of the of the CO2s insulating properties the time it takes to absorb and emit a photon. Each CO2 molecule is absorbing its neighbouring CO2s photon and all this time the heat emitted by the heat source continues. Their just passing the same photon around all the 0.03% CO2 molecules so where is all this continuous heat output being stored, it's certainly not in the CO2 molecules because there passing the same photon around again and again!

Nature's tacit instincts are very reliable, they are rarely wrong.

I just go with the flow and follow my instincts as I am not committed to any theories so I can discard a theory and accept parts of it later on, because with darkmatter, it has an overriding quality, its gravity is indistinguishable from matter. Faced with the affects of gravity antimatter and matter are indistinguishable, when this scenario occurs I fall back on my instincts.

your input to further this entirely possible scenario is just muted somewhat by bringing in the discredited darkmatter; darkmatter should only be brought out the hat when all else fails
mackita:- I understand what you mean with it but dark matter was never discredited as such - just some heavy fermion models of it.


Mar 25, 2018
This is an improvement as we have moved the source of heat back to where it belongs, the Sun, Radioactivity in the Earth's molten core with a small amount of tidal heating, a sinking feeling in the right direction.

The Earth's molten core is kept active by the gravity of the Moon and the Sun
mackita:- The volcanism of Jupiter moons (like Io or Europa) could be fed by tidal forces but at the case of Earth the effect of tidal forces will be rather weak already. An estimated 45 to 90 percent of the heat escaping from the Earth originates from radioactive decay of elements mainly located in the mantle. The heating of oceans by tidal forces would by way more intensive due to larger friction, yet it is calculated that on average tidal heating causes 3.75 TW on heat. That is about 1 mW/m2, whereas net solar input is estimated to about 240 W/m2, from which the greenhouse gas forcing is guessed to be about 2.5 W/m2.

Whoever was responsible for bringing CO2 into the ice age cycle has caused a lot of confusion and accusations of climate sceptics over the indisputable fact the Earth's climate is cyclical with warm and cool periods leading to regular ice ages that have been occurring for 5 billion years, it has got so bad it is being stated that the Sun is no longer the heat source as it is the CO2 which is solely responsible, we must give him his due though, blaming it on a miniscule CO2 molecule, only the Tate got one better with their blank canvas!

Nature's tacit instincts are very reliable, they are rarely wrong.

For "nature" to have an instinct, tacit or otherwise, would require it to have some form of realised life in its own right. Nature however, in the sense that you (mis)use it, is a semi-colloquial term used to encompass the extent of the material world surrounding us, whether this be the immediate environs, the entirety of the natural ecosystems of the Earth or indeed up to including the whole universe as it impacts upon Earth and humankind. "Nature", insofar as we know it, has no consciousness or being of its own and hence cannot demonstrate instincts or other volition.

The only way for your sentence to make any sense would be if "nature" takes some deistic or theistic form (i.e. is a god). In this case your religious argument would have to encompass animism, given that you are imputing motivations, actions, and outcomes to "nature", and this is a very different discussion to the one in this thread.

C02 is not the source of heat - the sun is the source of heat. No one disputes that. C02 and Ch4 are heat trapping gasses.

greenonions1 if your reading through the comments they are clearly stating the indisputable fact of the earth's climate, that it is cyclical and has regular ice ages.


Yeah this comments section should win a Nobel prize for physics rather than, you know, ACTUAL PHYSICISTS. #facepalm

Called Milankovich cycles. Well understood by the science community. Go read an introductory college text book. It is also understood that the current warming trend cannot be explained by the Milankovich cycles, or the feedback loops that seem to cause the offset in terms of temperature changes clearly being caused by these cycles. So granville - show us what is causing the current warming trend - with evidence please.

New report reveals a 23 year long pause in stratospheric temperature.
And what is your point? Stratosphere is one part of a highly complex system. It is cherry picking to go to on component of a system - and suggest that you can draw conclusions from that subset of cherry picked data. Facts - the earth is warming; ice sheets are melting; glaciers are melting; oceans are rising; oceans are warming; - but you can run off to your Watts up blog - and find some cherry picked data about the troposphere.....

mackita, the heliocentric model was conceived by Copernicus decades before Galileo's observations refined and confirmed it. You can't even get your appeal-to-authority fallacy right.
