Question: I've tried researching this question myself, but the only data I can find is over huge timescales, like situations where the continents have reformed back into a Neo-Pangea.

I'm not looking for any real drastic changes in positioning, just relatively minor things like seas disappearing or continents slightly shrinking or pushing into each other. 

Would there be any noteworthy changes at all, or would it be pretty much the same as today aside from some minor changes that wouldn't affect anything?

Let's just assume humanity suddenly stopped existing today for the purposes of the question, so they don't make any more changes to the world than they already have.

As always, I'm very grateful for any answers, and if you need anything clarified feel free to leave a comment and I'll do my best to clear things up.

Global Warming would continue for a while, if for no other reason than approximately 2.5% of CO2 is sequestered per annum.

At that rate, it would take 14 years to return to a CO2 value of 280ppm.

But in the meantime,

1. much polar ice has disappeared, and blue ocean absorbs more energy than white ice, and
2. the permafrosts are thawing, releasing lots of methane, which an even stronger greenhouse gas. This northern warming is causing even more methane to be released, in a vicious cycle.

Thus, it's very possible that most of the Greenland icecap will be melted, and also Antarctica, raising the ocean levels by 70 meters.
In addition to the previously noted changes due to climate and normal geology, the sudden removal of humans a la Discovery Channel's [Life After People](https://www.history.com/shows/life-after-people) would quickly lead to the breakdown of electrical and mechanical infrastructure, including pumping stations (e.g., the [California Aqueduct](https://en.wikipedia.org/wiki/California_Aqueduct), [New Orleans' pumping stations](https://en.wikipedia.org/wiki/Drainage_in_New_Orleans), and the Netherlands' [pumping stations in Flevoland](https://www.visitflevoland.nl/en/on-expedition/heritage/pumping-stations-in-flevoland/)), with the obvious results. In the longer term (a few centuries at most, according to Discovery), the majority of earthen and concrete structures are likely to fail, which includes essentially all of the world's dams, dikes, and levees. Their collapses will cause significant flooding, erosion, and scouring of low-lying areas downstream, and some river channels will be changed significantly enough to still show the effects a millennium hence.

Earth's cities and highways are also likely to be largely buried in vegetation (again, per Discovery), with the result that urban and linear features that are prominent from the air or even space will become much harder to see.

The disappearance of humans will also eliminate agriculture and logging, which is likely to reduce silt and fertilizer runoff in most places, with at least some visible changes in watersheds. (For example, [mangroves](https://go.nasa.gov/2FY1CnO) can be expected to make a larger comeback in some rivers; clear-cut areas of the Amazon and other forests will recover to some extent; and a number of river deltas like the [Ebro's](https://go.nasa.gov/2Ik9OQV) will stop growing so quickly and may actually erode.) The Aral Sea may make a comeback as well.

Astronomy might also play a small part; according to [Wikipedia](https://en.wikipedia.org/wiki/Impact_event), there's about a 20% chance of an asteroid strike large enough to create a crater actually hitting land and doing so.

By the way, spacecraft, even the ISS, are too small to make much of a mark, and what little damage they do cause would be hidden by vegetation and weathering very quickly (years, or decades at most).
