So it was spinner faster a decade ago…will it be even slower a decade from now? Would that be significant in anyway? People are worried about global warming because they feel the effects won’t be there until we’re all dead anyway but this shit seems a little more short on the time window.

It might be slower a decade from now, and then the fact that it's slower than the rest will make it speed back up again. It's likely just a slow oscillation between faster and slower as the moving liquid outer core stops it from ever being truly in sync.
