The Glacial-Interglacial Cycle is Driven by Orbital Forcing

[EMH]

What do ice cores reveal about the past?

By preserving evidence of ancient temperatures and greenhouse gases, ice cores show scientists how much our planet has changed.

nsidc.org

extracted from the Greenland Ice Sheet preserve 130,000 years of climate history. Cores from the Antarctic Ice Sheet preserve up to 800,000 years



So, you are arguing that, despite the fact that 97% of Earth ice kept right on growing according to the ICE CORE DATA, somehow we were in an "interglacial"....

defined by Google as...

During an interglacial period, glaciers retreat and sea levels rise.



SORRY, the "glaciers" did not "retreat" when THEY GREW NEW ICE LAYERS EVERY YEAR....

It says here "Variations in tilt angle modulate seasonality, especially in high latitudes", but not impact on the global average isolation.

So, you have volunteered as a Democrat Party "science expert," so surely you can answer some simple climate questions...



1. Why does one Earth polar circle have 9+ times the ice of the other?
2. Why is there ice age glacier south of Arctic Circle on Greenland but no such ice age glacier north of Arctic Circle on Alaska?
3. If the oceans are "warming" why is the record decade for canes still the 1940s?
4. If the oceans are "rising" why can't we see one single photo of land sinking?
5. How did Co2 thaw North America and freeze Greenland at the same time?

And proves everything I have said.

1) Antarctica holds about 90% of all the world's ice. "The volume and mass of ice on the land changes little in the summer as a fraction of the amount in winter because the volume and mass are so large," says Cecila Bitz.
2) Not enough precipitation in those parts. Orographic precipitation in the mountains squeezed out all the moisture.
` 2a) The lack of continental ice sheets in Alaska during the Last Glacial Maximum (LGM; 26–19 ka) has long been attributed to extensive aridity in the western Arctic.
3) I have no idea what "canes" is but... Earth did cool somewhat between 1940-1970 due to a postwar boom in aerosol pollutants which reflected sunlight away from the planet
4) the change of levels i only a few millimeters per year, but there is a video here showing the difference over 130 years
5) Average temperature is correlated with latitude, but it is not directly controlled by it. See this map of average temperature across the globe.
---
How hot and cold air are able to move across land matters a lot. So things like plains and mountains change where the air can go. Ocean temperature also matters, and similar to the air, there are currents and parts of the ocean are warmer or colder because of those currents than you would expect just based on latitude alone. Here's a map of that.

Delusional...

Your "interglacial," a period you claim is warm and glaciers melt, observed 97% of Earth ice GROW STRAIGHT THRU....
