Bogus Ocean Suffocation Crisis

Welcome back everybody. I promised my next video would be about the Arctic ocean, but I had a few colleagues asked me about the bogus ocean suffocation crises that are being pushed by the media. About a week ago, the Seattle times had the big headlines that low oxygen levels in the Pacific Northwest are a silent climate change crisis. And this is nothing new. This suffocation crisis has been pushed for at least the last five years. In 2016, one media headlines said that, the oceans would suffocate by 2030. The New York times has also pushed this idea that the oceans are rapidly losing their oxygen. And they all do this because it's clickbait and is profitable. Not only did the New York times push this headline, but they took out a Google ad to push this crisis type headline. So, so all the media push this but it doesn't make any scientific sense.

International Union for the Conservation of Nature (IUCN) misrepresent oxygen changes

Now the IUCN  is the International Union for the Conservation of nature. And there's a lot of good scientists that I really appreciate, who are trying to protect the environment, but they're also dependent on donations. And so they are not immune to trying to push a crisis in order to get more funding. Now they just recently pushed this "DEOXYGENATION is a wake up call to save our suffocating seas". And they blame climate change for causing a dramatic loss in life-sustaining oxygen.

They attributed that loss to three main causes. 1) They said that that CO2 is causing a warming of the ocean and warmer waters lose oxygen quicker. 2) They blamed stratification of warming surface layers that prevents vertical mixing of water. And so that prevents oxygen from the atmosphere from reaching deeper layers. and 3) They push eutrophication, which has nothing to do with climate change, but they pushed it anyways.

So I want to talk about eutrophication first. Now dead zones in the oceans, due to eutrophication, has been a known problem for several decades now, and many places are attempting to try to resolve this problem. What happens is the dumping of nutrients from agricultural waste, or sewage into the rivers enters the oceans and all these nutrients create a boom in algae growth. But once the algae growth stops, algae dies, and the decay consumes all the oxygen. Without oxygen, the fishermen in the Gulf of Mexico would see that these dead zones seen in red, where all the fish would leave. And so it was a crisis but this is not just happening at the Gulf of Mexico

Known sites of hypoxia due to eutrophication

All these little red spots here represent the places around the world. And we see it's usually around major population zones where this waste is being dumped into the ocean. This has nothing to do with climate change, but is something we definitely must deal with it's, it's a problem.

So the IUCN is arguing that since the 1960s, the global oceans of loss, about 2% of their oxygen that they blame on global warming; kind of sprinkling this bogus climate crisis with a little bit of truthful physics by saying that as water warms, it holds less oxygen. But this ignores the real issues. Dr. Francisco Chavez is a Peruvian oceanographer who is now chief scientist at the Monterey Bay Aquarium Research Institute.

Data from Chavez 2011

And he looked at the effects of upwelling along the coast of Peru, on oxygenation of the waters. He looked at the data from over 700 years and during the Little Ice Age when the waters were much colder (that period of time is shaded in a light blue). And during that time, the waters were highly oxygenated (upper panel). Then around 1800, as the water started to warm, and the global temperature started to warm, the amount of oxygen in the water dropped. And this at first glance would seem like it's consistent with the global warming theory. But if you look deeper, you see the real significance has to do with upwelling.

Chavez looked at how much nutrients were found in the upper levels of the water. And they noticed that what happened as the earth warmed as it came out of the little ice age, upwelling increased. That brought nutrients up to the surface where plankton could grow. And what you see then is when that happened, there was this tremendous amount of productivity that's happened (lower panel).

So the warming we've experienced over the last hundred years has been a great benefit to the whole Marine ecosystems. Now you'd expect from this extra photosynthesis that because photosynthesis produces oxygen, and productivity was great, there'd be more oxygenated waters. But there's another issue just like the eutrophication. When those particles of organic matter that was created during photosynthesis start to sink and decay or be digested, they consume oxygen.

A recent paper in 2018, also created a spurt of media climate crisis, uh, claims.  Chavez was a coauthor of Breitberg (2018) "Declining oxygen in the global ocean and the coastal waters". They noted it's an "important paradox to consider that the large scale effects of future  deoxygenation that nutrient rich coastal systems, due to upwelling, are associated with oxygen minimum zones, but also support some of the world's most prolific fisheries."

Now it, at first glance, it appears that there's a great paradox here. That greater amounts of photosynthesis would cause a greater depletion of oxygen. But if you understand that more photosynthesis, creates more organic matter in these upwellings zones, and the more organic matter that's produced, the more it decays and consumes oxygen. And it's in these upwelling zones that we see the greatest oxygen minimum zones. If we look at a global illustration of oxygen minimum zones around the world (below) in dark blue, the greatest amount of upwelling are also the greatest places of oxygen minimum zones.

If we look at this illustration about oxygen concentrations as we drop in depth, we see at the very surface that the oxygen concentrations are at their highest, but that's in just the top 100 meters of the ocean. And below that photosynthesis stops. We see that the oxygen begins to be consumed as organic matter sinks, and by the time it reaches about one kilometer depth, we create these oxygen minimum zones where all this decaying organic matter consumes most of the oxygen. 

And then once you drop below those oxygen minimum zones, the oxygen in the deeper water starts to increase again. And that's because there's very little organic matter left to decay. And the mixing of deep cold waters that have been highly oxygenated and brought from more polar regions, start to add oxygen to the water. 

Now to understand why this hundred meter depth marks the difference between super saturated oxygen in the surface layers and a declining amount of oxygen below that, we have to understand how light penetrates the water. Here in this illustration, we see the sunlight is broken up into his basic colors or wavelengths.

We see that that red light, which is really critical for photosynthesis, really doesn't penetrate past the first one meter. (Infrared that is produced by greenhouse gases, can't penetrate any deeper than about one micron. So it doesn't warm the oceans directly.) By the time you get to 10 meters, the yellow light can't penetrate any deeper. Green light can't penetrate much deeper than 50 meters and blue light, which is another critical wavelength for photosynthesis, can't penetrate any deeper than a hundred meters.

Now, this is an average sometimes in very clear water, you get a little greater penetration, in murky waters you have a little bit less. But we we can break up these depths in a very general way. We'll call the upper surface later that euphotic zone where there's enough sunlight to foster photosynthesis. And then below the euphotic zone, you get a little bit less light in the dysphoric, but not enough for photosynthesis. In the aphotic there is no light whatsoever, and in those regions photos without photosynthesis, decay in digestion dominate so  oxygen not produced only consumed, so oxygen minimum zones are created.

So let's look at the paradox of why upwelling zones not only create the most abundant areas of rich and diverse marine life, but why they can also cause some deadly consequences.  In the lower layers within the zones where there's no photosynthesis, decay and digestion dominate and they consume all the oxygen as they do that. The decay and digestion releases all these nutrients that can now be recycled into the surface above. Now the winds, and this happens typically along the west coast of all the continents, as they blow towards the equator, the winds cause the water to move away from the coast, and this causes the subsurface water to rise and replace it. 

As that water rises, this water without oxygen will cover some of the sea floor, near the surface where invertebrates live. Some of the fish, if they can, move away because of lack of oxygen, But other invertebrates that aren't so mobile, may die. And this was noticed by crab fishermen in Oregon when they brought up their crabpots and found dead crabs in them.

But the upwelling also has all these nutrients. It injects nutrients into the sunlit zone, and this enables a burst of photosynthesis and it's these phytoplankton blooms that are the basis for the whole food chain for this very robust ecosystem. And, at the same time because photosynthesis dominates, it's super saturates, the surface waters with oxygen.

Now, the second thing that the promoters of a climate crisis push is this idea of stratification, meaning that because the water on the surface is warmer, it won't mix with the colder water below it. And so they're arguing that CO2 warming is going to increase the stratification. Now, anyone that has studied oceans or lakes understands that this kind of stratification happens every summer and it breaks down every winter, but this is sort of the sprinkling of scientific truth used to make this bogus climate crisis narrative seem more plausible.

So let's look at a peer reviewed study from 2015 that examines the oxygen profile throughout a full year and through the seasons from summer to winter. This is from a station near Alaska around 50 degrees latitude north. What you can see here is the blues are our regions below the surface that are unsaturated with oxygen, meaning that at that temperature, these waters could hold a lot more oxygen than they do, but they don't because of decay and digestion. The yellow and the red show areas of super saturation, meaning there's far more oxygen in those surface waters, then you would expect to diffuse in from the atmosphere.

The purple thick line shows the stratification depth and how it changes throughout the season. So if we look at the summer from June through October, when the waters are warm, we see that the strata is  definitely very shallow. But we also see this is a region where there's super saturation and often this shallow stratification enables greater photosynthesis because it prevents turbulence that can carry phytoplankton down to deeper depths with, with less light.

As we move into the winter, the early fall and late spring with colder temperatures, we see this stratification gets deeper, but we also see there's much less oxygen there. Even though you have this deeper strata of water now, it's mixing in unsaturated water. So this deeper stratification, this deeper mixing of water, is not always a benefit for supplying oxygen. And if we look at the waters below a hundred meters where decay and digestion dominate and get rid of oxygen, we see this unsaturated water is really not affected that much by the changes in the stratification above it.

So if you understand the science, if you understand the marine systems, then you understand that there is no climate change oxygenation crisis. When people are trying to manipulate your opinions, it's easy to mix in a small fraction of truth, a small fraction of science with a large fraction of lies to push an earth crisis that makes people afraid, makes them concerned, & makes them willing to accept different solutions that are pushed by politicians or media clickbait.

You must be aware of this vicious circle of exaggerated crises. The media will promote click-based crises for a profit, and then politicians and researchers seeking funds will claim that they have solutions for these non-existent crises. Beware! 

Now as promised before, my next video will be about how Arctic ocean ventilation biases the global average temperature.

But until then, embrace the renowned scientist Thomas Huxley's advice that skepticism is your highest of duties and blind faith is the one unpardonable sin.

"How Antarctica Caused Global Cooling or Why Earth Remains in Ice Age Mode for Next 200 Million Years"

Oceans are a tremendous reservoir of heat. The upper 10 feet of ocean water holds more heat than the earth's entire atmosphere. Due to the formation of the Antarctic Circumpolar Current, enabled by plate tectonics, Antarctica became thermally isolated from the rest of the earth initiating 1) a permanent ice cap, 2) extensive sea ice that extruded cold brine that filled the ocean's bottom water, and 3) Intensified upwelling that increased productivity that drew down atmospheric CO2 to current levels. As a result of increasing cold Antarctic Bottom Water, oceans ventilated its its displaced ancient bottom water heat. As a result of a 50 million year cooling trend, the earth is now locked into a fluctuating balance between cold ice ages and warm interglacials

Transcript of Presentation below:

Welcome back, everybody. Thanks for all the kind comments today. I want to discuss what I call the Antarctic refrigeration effect. And if you understand that, you understand why the earth will remain in ice age mode for probably the next 200 million years. Now, climate change is a huge in complex problem, and it's akin to the, the Indian, east Indian parable of the blind men characterizing an elephant. Unfortunately, there's one cadre of scientists who are trying to force a singular viewpoint: Carbon dioxide is the climate control knob. But once you understand how important ocean circulation is, you just might be convinced that the greenhouse gas effect is really the tail wagging the elephant.

If you look at ancient climates, we'll see that 90 million years ago during the Cretaceous that the earth's continents were warm from the polar region to the equator, and Antarctica was a tropical rainforest. It had its own dinosaurs, Glacialisaurus sp. Well, the dinosaurs had a major extinction event about 66 million years ago when an asteroid collided with the earth and caused the extinction about seventy-five percent of all global species. So I'm going to skip ahead to the Eocene and the cooling trend that happened about 50 million years ago. Now temperatures back in the during the Eocene, the Arctic's Ellesmere island summer temperatures, even though it was, it was a polar place was about 68 degrees Fahrenheit.

The coldest month only dropped down to just above freezing. Yet today we look at Ellesmere Island, which is adjacent to Greenland, and the average temperature there is about 2.3 degrees C. So we've had a tremendous cooling trend since then. And along with that cooling trend was the development of polar glacial ice caps.

Now we look at around 34 million years ago, Antarctica started to have its permanent ice cap, but it then took until about two and a half million years ago for a permanent ice cap to form on Greenland. So the question becomes if CO2 is the control number of temperature and ice formation, why is this this 15 to 30 million lag between Antarctic in Arctic ice cap formations now to understand the earth climate before the great global cooling trend began, we have to go back to the age of dinosaurs back then the continents were all connected in one continuous continent, known as Pangea with the lack of glaciers.

50 million year cooling trend from the Eocene to the present

During the age of dinosaurs, there were higher sea levels which created shallow coastal seas. And there was the creation of the Tennessee, another shallow sea shallow seas heat up more quickly and evaporate water more quickly. And that causes more warm salty water to sink to the ocean floor.

Pangea with shallow seas (purple)

So at the beginning of the Eocene, the oceans of the world were dominated by warm, salty, deep water (WSDW), the oceans bottom waters (WSDW) were about 10 to 13C warmer than they are today. And that warm water would also upwell around the Antarctic and be carried back to the equator by a current known as the Antarctic Intermediate Water (AAIW). But that dynamic was about to change as Pangea broke up throughout the age of dinosaurs.

And pretty soon Antarctica became isolated as it is today. When Antartica separated from south America, Australia, and Tasmania, it allowed for one continuous current to loop around Antarctica known as the Antarctic Circumpolar Current (ACC). And it had had some major impacts on the world's climate. That current blocks, the warm sub-tropical waters from entering Antartica waters and that initiated extensive sea ice growth and glaciation.

It also increased upwelling and diatom productivity, which is associated with the evolution of baleen whales that now we're able to just filter feed through the ocean. That tremendous productivity caused more CO2 sequestration, which caused the amount of atmospheric CO2 to drop.

Antarctic Circumpolar Current

And now the Antarctic Circumpolar Current through the Antarctic intermediate waters would feed all the rest of the world's oceans in the Aaliyah scene lasting from 34 to 23 million years ago, the Antarctic circumpolar current deepened and strengthened the formation of sea ice now cause cold brine rejected from that sea ice to sink to the bottom and replace the warm salty water. And that began to change the temperature profile of our oceans.

Changing Oligocene ocean bottom waters from warm salty WSDW
to cold Antarctic Bottom Water (AABW)

And that began to change the temperature profile of our oceans.

Now due to the shape of the earth and its tilt of this axis, the sun more intensely heats the earth around the equator relative to the polar regions, which receive more diffuse sunlight. So the polar regions don't heat up much. And then due to the polar nights where there's no sun at all, it radiates all that heat back to space. The current temperatures in the polar regions are maintained by a flow of heat from the tropics into the polar regions, through ocean currents and atmospheric currents, uh, such as the Gulf stream or the Kuroshio current.

And we can see this illustrated here in this diagram where there's an excess amount of heat and the equator relative to his temperature and that excess heat is transported to the polar regions, which warm those regions.

Heat transport from warm tropics to warm polar regions

So based on those dynamics, I like to refer to the cooling that's been happening for the last 50 million years as the Antarctic refrigeration effect. Now every refrigerator has this compressor & fan apparatus, which removes heat from the refrigerator and blows it out the back. Now it's not quite analogous, but the polar regions remove heat away through radiation especially during the the polar nights.

Now, if a refrigerator door is left open, then the heat is blown out the back of the refrigerator just re-introduced through the front. So there is no cooling, but if you shut the door, the refrigerator cools and the Antarctic circumpolar current shuts the door on the Earth's temperature circulation Now is heat is blocked from entering the Antarctic southern waters increasing sea ice.

More extensive sea ice creates more brine ejection, which sinks to the bottom and cold salty brine replaces the warm salty waters. Now the formation of cold Antarctic bottom water sets the stage to create the profile of temperatures we see throughout the modern day oceans. We see that the bottom waters are dominated by Antarctic bottom waters and that cold water helps feed, uh, the Antarctic intermediate waters, which transports the cooler temperatures to the equator in, into the Northern hemisphere.

Ancient warm salty deep water replaced by AABW & North American Deep Water (NADW)

And here's another way of looking at that profile. You have Antarctic bottom water on the bottom. You have North Atlantic deep water above that's been formed in the Arctic under the cooler conditions of today. We see the Antarctic, intermediate Water is flowing up past the equator and we still see some sinking warm salty water due to evaporation happening in the Mediterranean.

And here's a profile of the Atlantic at about a thousand meters depth. We see this warm salty water coming out of the Mediterranean Ocean.

Now the sinking Antarctic bottom water, which is the coldest water in the oceans mixes and lowers the temperature of the North Atlantic Deep Water. And together that feeds the cool Antarctic intermediate waters that moves towards the equator and affects most of the upwelling regions around the world.

Now, by looking at the Pacific Ocean todeay, we can appreciate the power of upwelled cold water that changes the global temperature during the La Ninas. Warm waters are pushed over to the eastern side of the Pacific and cold waters rise from below to replace that warm water with cold water.

If we look at satellite temperature data, we see the major drops in global temperature happened during Linea events as represented by the red arrows.

The problem is the Pacific cold water upwelling didn't begin until 4 million years ago, Before the Arctic region began to form its glaciers and ice caps. And the reason for that is this Antarctic refrigeration effect had to build up the Antarctic bottom waters to a large enough volume to feed cold Antarctic Intermediate Waters, raising it close enough to the surface to allow it to be upwell and then affect the Earth's climate.

Now around 2.5 million years ago, Greenland's permanent ice cap took hold. And that correlates with the closing of the central American Seaway by the rise of the Panama isthmus connecting North America to South America. Now, some researchers say that this blockage of the central American Seaway, enabled the glaciations to begin, but others say that it delayed the glaciation. There's not enough time to talk about whether that's true or not, but the changes in ocean circulation around 2.5 million years ago, we're not just relegated to the isthmus of Panama, but happened around the Bering Strait, and around Indonesia.

So we see there was a tremendous change in circulation. Now, one result of the creation of the Panama isthmus that might be of interest, is it allowed the animal fauna between North and South America to move upwards or southwards. If you look at the brownish green silhouettes, those are all South American animals that moved into North America and the silhouettes in blue are North American animals then moved into south America. That causes one to question if temperature has anything to do with similar kinds of migrations

To summarize 50 million years of global cooling, we start with the ESC a time period 50 million years ago when carbon dioxide was a a thousand parts per million or greater in the atmosphere in global atmospheric temperatures, as well as warm salty, deep water was at least 23 degrees Fahrenheit, warmer or 13 degrees centigrade warmer than today by 34 million years ago.

The Antarctica Circumpolar Current was now blocking any kinds of flow of subtropical, warm water from reaching Antartica. And this caused three critical things. 1) it allowed the initiation of Antarctica's permanent ice cap that persists today, 2) it caused extensive sea ice to increase, which caused brine rejection, which added to the volume of the cold Antarctic bottom waters.

And 3) the current also increase upwelling. It caused high productivity from diatoms, the evolution of the baleen whales and that productivity sequestered more and more CO2 dropping CO2 down to levels of 300 parts per million to 700, depending on your models, which is lower than today in many cases. And surprisingly, as the Oligocene proceeded, the late Oligocene was warming despite the continued drawdown of carbon dioxide. By the Miocene, the CO2 was down around 400 parts per million, and, but global temperatures were seven degrees to eight degrees centigrade, 14 degrees Fahrenheit warmer than today.

And so some models said that that CO2 had to be higher in order to justify those temperatures. But we could also say that the reason we saw this warming in the late Oligocene, or we saw it in the Miocene as, as Antarctic bottom waters, increasingly, uh, replace replacing warm salty waters in the bottom, the ocean, it raised those ancient, warm waters to near the surface where that warm water could ventilate as heat back to the atmosphere by the Pliocene, which ended around 2.5 million years ago, we saw the initiation of the Greenland's permanent ice cap that was partly associated with the Panama isthmus as well as other changes in plate tectonics, which caused changes in ocean circulation. At that point, CO2 was again around 400 parts per million and upwelling of warm water. Up until that point had kept temperatures around three degrees or 5.5 degrees Fahrenheit warmer than today.

Temperature changes between cold ice ages and warm interglacials

Now the growing amount of cool upwelling waters caused the Pleistocene 2.5 million years ago to reach a point where it's very sensitive to any changes in energy imbalances on earth, that caused the Earth's climate to fluctuate wildly between glacial cold periods in interglacial warm periods.

We had the warm interglacial the previous one hundred thousand years ago that was warmer than today by about four to five degrees centigrade. And then the last glacial maximum temperature was down to about a minus 11 cooler than today

While CO2 warming effects have raised earth's temperature to present levels, CO2's absorbed wavelengths are saturated. More CO2 will have reduced warming effects going forward. On the other hand, more CO2 increases collisions with O2 and N2 allowing those air molecules to release heat absorbed from conduction with the ground to be radiated back to space

Those cooling effects offset warming, reduce dangerous inversion layer heating, and maintain a balanced climate
