I have a theory, on what causes glacials and interglacials

[ultron]

During interglacial, there is decreasing weight on land. This reduces tectonic activity. The result is decreasing heat under the ocean and consequently decreasing temperature. This is how interglacials trigger glacials.

During glacial, there is increasing weight on land. This increases tectonic activity. The result is increasing heat under the ocean and consequently increasing temperature. This is how glacials trigger interglacials.

We know, the ocean is one of the two biggest sources of heat on Earth. The other being the Sun. This is why places near the sea, like Iceland, is much warmer, about 30 C warmer, than places of similar latitude but far from the sea, like Siberia.

This chart shows the alternating occurrences of glacials and interglacials.

You can see in this tool that the ocean is one of the drivers of climate. It is one of the main sources of heat on Earth. Even if there is no Sun, Earth would be considerably warmer than the Moon.

What do you think?

no sun still warmer than the moon what.

isn't radioactive decay from the core the next biggest source on the earth

Tectonic activity converts kinetic energy into heat energy. That's why the bottom of the ocean is hot. There are many planets that do not orbit a star and wonder the galaxy as orphans and many of them are warm enough to support life.

What is known is that, from the last glacial to this interglacial, happened very fast as temperature increased 10 C and CO2 increased from 180 ppm to 280 ppm over a few hundred years. Ocean outgassing of CO2 due to increased temperature cannot account for this. If the ocean outgasses CO2, the ocean would also outgas O2, and the composition of the air would not change. We know in the summer, CO2 decreases by about 6 ppm due to plants absorbing CO2 into their leaves in the summer, and in the fall, CO2 increases by about 6 ppm due to plants shedding leaves which decompose. The only plausible reason, in my opinion, that CO2 increased from 180 ppm to 280 ppm during the most recent transition, was due to tremendous tectonic activity, volcanoes and hot vents under the oceans, after the land became so heavy with glacier buildup that the tipping point was tripped which made Earth's tectonic activity go crazy high.

hmm okay

I am curious, do you happen to believe in evolution by any chance?

I do not believe in evolution. I believe in mutation and adaptation. Humans are clearly becoming more stupid by the day.

Recent re examination of ice core data confirmed no lag between change in CO2 and change in temperature, that these two moved together in lockstep. This suggests that higher tectonic activity was the cause for increase in temperature from the LGM to the Holocene.

However, what I do not agree with the article is I do not think CO2 increases temperature. I think tectonic activity increases temperature as kinetic energy is converted into heat energy, heating up the ocean.

Ah, just curious.

But you are making the mistake of assuming correlation and causation. You can easily make similar assumptions about sun cycles having the primary effect on climate change, along with a number of other theories.

Nothing you have posted shows tectonic activity being causation, rather than correlation for the rising temperatures.

During interglacial, there is decreasing weight on land. This reduces tectonic activity.

Tectonic activity has nothing to do with the mass of land but rather the underground volcanic eruptions and due to the formation of new layers in the crust on lava cooldown.

If there is heavy ice buildup on land, the large pressure will trigger more tectonic activity. If there is very little ice buildup on land, the small pressure will trigger less tectonic activity. Earth's tectonic activity is at an all time low, with no major earthquakes or volcanic eruptions, suggesting Earth's temperature is falling and going into the next glacial.

Tectonic activity is one of the two main sources of heat on Earth. The other being solar radiation from the Sun. Tectonic activity is causal on temperature.

Think about it. What can possibly cause CO2 to jump from 180 ppm to 280 ppm and temperature to jump 10 C over only a few hundred years when the transition to Holocene occurred? It has to be because of heightened tectonic activity. What could have possibly cause this heightened tectonic activity? It must have been the huge amount of pressure exerted by the huge amount of ice buildup on land.

I have another theory. That the earth's temperature is mainly dependent upon the water vapor in the atmosphere. During glacial period the climate is cold and the atmosphere is dry. Through the dry air the sun rays pass without much refraction. Which means that the earth receives greater irradiance. As earth is mostly covered with water, this greater irradiance causes greater evaporation of water from the oceans. When water vapor increases in the atmosphere the planet warms up. But this water vapor in the air also causes the sun rays to refract. Which results in lower irradiance received by the surface of earth. This decreases the evaporation, the air dries up and the planet cools down. And the cycle continues.
