..... I'm wasting my time.

You are wasting your time spamming with climate porn.

I'll stick with "orbital perturbations," of which Milankovitch cycles are a subcategory. Let's check our friend Wikipedia.

https://en.wikipedia.org/wiki/Milankovitch_cycles

The term is named for Serbian geophysicist and astronomer Milutin Milanković. In the 1920s, he hypothesized that variations in eccentricity, axial tilt, and precession of the Earth's orbit resulted in cyclical variation in the solar radiation reaching the Earth, and that this orbital forcing strongly influenced climatic patterns on Earth.

We're overdue for another ice age.

Wrong. We are currently in an interglacial period of the Quaternary Ice Age.

Since the Quaternary Ice Age is defined as a period when some ice sheets existed throughout, notably those of Antarctica, isn't this a bit in conflict with your prior claim that "All the ice is going to melt!" I think if you just answer "Sometime...." it is a refutation of any causative link between man's carbon emissions and the melting of all the ice.

For all practical purposes, we're in an Ice Age when half of North America is covered by glaciers. If you want to nit pick and shout about "Interglacial periods of the Quad..." go at it. If you want to state it as "we're overdue for the end of the current interglacial period" that's fine. Playing with the words does not change the facts.

The facts are that we are headed for a much colder global climate.

Here's your facts.

Long Debate Ended Over Cause, Demise Of Ice Ages? Research Into Earth's Wobble
Date:
August 7, 2009
Source:
Oregon State University
Summary:
Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years -- they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis.

... the known wobbles in Earth's rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.

...The melting was first caused by more solar radiation, not changes in carbon dioxide levels or ocean temperatures, as some scientists have suggested in recent years.

....Sometime around now, scientists say, the Earth should be changing from a long interglacial period that has lasted the past 10,000 years and shifting back towards conditions that will ultimately lead to another ice age unless some other forces stop or slow it.
