And, for the umpteenth time, you have YET to identify what caused that glaciation. Plate tectonics didn't do it. The sun didn't do it. The atmosphere didn't do it. Ocean currents didn't do it.
I really do hate to break it to you but the ocean stores the heat from the sun and distributes that heat. That's why the planet is warming up. But don't worry, another glacial period will stop that.How many of these is it going to take before you admit that temperatures have been falling for 6,000 years, that the Earth reached it interglacial peak with the Holocene Climate Optimum?

Natural variability can explain much of Earth's average temperature variation since the end of the last ice age, but over the past century, global average temperature has risen from near the coldest to the warmest levels in the past 11,300 years.www.climate.gov

Global temperatures over last 24,000 years show today's warming 'unprecedented'
A University of Arizona-led effort to reconstruct Earth's climate since the last ice age, about 24,000 years ago, highlights the main drivers of climate change and how far out of bounds human activity has pushed the climate system.phys.org

Another Ding mistake.
Disruption of heat circulation from the Atlantic to the Arctic which I have told you at least a dozen times. You already know why the ocean currents are initiated and change.
See graphs above sycophant.
No need. Simple physics calculate the theoretical surface temperature of a doubling of CO2 to be 1C. Convective currents reduce that number by whisking heat away from the surface towards outer space.
The vast majority of heat is stored in the ocean. The ocean distributes that heat to the rest of the planet. The ocean is warming up because the sun is warming it. The planet is warming up because the ocean is warming up and the Arctic is naturally thawing like it always does after a glacial period.
So what?
So does the atmosphere. So does the sun. So does the Earth. So what?
The ocean is currently getting warmer due to increased CO2 in the Earth's atmosphere. You have not shown ANY OTHER SOURCE for that warming.
I find it hard to believe that someone capable of operating a keyboard could be stupid enough to make such an abysmal argument. But, you seem to manage. I want you to do your very best to ACTUALLY answer the following question: Why is the ocean warmer now than it was ten years ago? What has happened during those ten years that is causing the average temperature of the ENTIRE ocean to go up?
The sun. Just like it always has. The sun heats the ocean. The ocean stores and distributes the heat which is what determines climate.
I'd say that believing that the ocean stores the majority of earth's heat and believing the ocean distributes that heat and believing that climate is based upon the distribution of that heat is the opposite of an abysmal argument. I think it is a very sound argument. I think your unreasonableness is politically motivated.
The temperature of the Earth is ENTIRELY dependent upon the energy flux at the boundaries of the Earth system. Where does ANY of that affect that flux.
The heat the earth receives from the the sun is remarkably constant with respect to similar stars. So what's coming in is pretty constant whether the planet is in an interglacial period like today or a glacial period yet the planet's mean temperature changes quite drastically. The reason it changes quite drastically is that glacial periods are triggered by a disruption of heat from the Atlantic to the Arctic which triggers glaciation in the Arctic. This glaciation increases albedo which serves as a negative feedback amplifying the initial cooling such that it eventually affects the climate of the entire planet. Eventually though, heat circulation from the Atlantic to the Arctic is eventually restored starting the long process of thawing and warming up. The sun during all of this continued to crank out what it always cranks out. This means that absent a change in how the ocean distributes that heat the earth would naturally continue warming even more than it has in any interglacial period before it. The native state of the planet is warmer than it has been at any point since the planet became bipolar glaciated but ocean currents are constantly seeking not only equilibrium in temperature but in density as well. As such changes in ocean currents will continue to happen as a result of uneven warming. But you're a political hack and don't give two shits about the science.
What specific changes are you talking about? The glacial-interglacial cycles? D-O Events? The cooling since the Mesozoic? The CO2 and temperature changes in all but those D-O events happen at a very small fraction of the rate at which they are currently taking place.
What do you actually mean by "drastically"? Rapidly? Of exceptional magnitude? Both? Something else altogether? And certainly disrupting the flow of thermal energy from the equator to the poles will cause the poles to cool, but, quite obviously as well, it will also cause equatorial regions to warm by the exact same amount. As you noted, there is essentially zero change in the amount of TSI. The only thing that's changing is where that energy is going. There is no change in the amount or rate of energy coming in to the planet and no change to the amount or rate of energy leaving. So what is causing THE PLANET's temperature to change.
Now there's a new one. If you now claim that's significant, you are going to have to accept that the loss of albedo in the current regime is also significant. And with no change in TSI, equatorial water temperatures will be going through the roof. That increase will cause at least as much CO2 to come out of solution as is going into solution at the poles. And the differing angles of incidence at the equator and the poles will minimize the effectiveness of the albedo change. The longer path length for light striking the poles will increase the opportunity for it to be absorbed by GHGs, reflected by particulates or aerosols. If this is your line, I think you need to explain why the polar ice caps, which have been present for at least the last 2.5 million years, have not forced the Earth into a constant snowball state.
And how is it restored? You posit no change in sunlight. Tectonic movement does not take place in a periodic fashion to support the 30 glacial-interglacial cycles of the last 2.5 million years. You now have permanent ice pack well down below polar latitudes providing constantly high albedo. The cold will keep CO2 in solution. WHAT, then, brings the Earth out of the snowball state in which you've placed it?
You do know how to dig yourself a hole.
I note that you have assumed no other mechanism is possible without the benefit of any supporting evidence.
The native state of the planet? What the fuck is that supposed to mean?
I have no idea what you mean by native state of the planet, but you have repeatedly told us that previous interglacial periods were warmer than today. And the planet has had ice at the Arctic for at least 2.5 million years and at the Antarctic for at least 35 million years. So, you're comments do not work with this claim.
Seeking? If this is so, how, after several billion years, does any temperature or density differential still exist?
Uneven warming acting in concert with that oceanic "seeking"?
You are just astoundingly stupid. I cannot fathom how you can put this down and seriously think anyone is going to buy it; that anyone will fail to see the show-stopping flaws that just keep on coming.
The same way it is disrupted; changes in salinity, density and wind patterns.
It's pretty well known that ice reflects incoming sunlight and is one of the reasons for extensive NH continental glaciation when the temperature threshold is reached for NH glaciation. Maybe look it up.
