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.
"Is removing people sufficient to stop global warming?" Good question. Answer is not clear. If we have passed the tipping point for arctic permafrost collapse, arctic ocean being ice free in summer, then we may release huge amounts of methane clathrates.

On top of this while oil has to be pumped, natural gas is often under pressure. As distribuiton systems break down, more methane is released.

Net result: ALL of antarctica and Greenland melt over the space of that thousand years.

So we have an new continent free from ice in the south, we have a new archipelago of islands where Greenland was. We have new ecologies in the arctic regions, and the ocean shoreline moves in a bunch.
