Most climate change denialists don't know how science works. Or, if they do, they cynically prey on the public's ignorance. I'm not up to date on sea level data, but even if what you say is true, you didn't just disprove climate change and proved that scientists are a bunch of conspiratorial UN socialists.
Multiple lines of evidence all feed into AGW as a theory. No area of active scientific research has everything fit together neatly. Anyone who has spent a cursory amount of time genuinely researching the issue knows this. But the approach that denialists take is decontextualizing one piece of evidence and claiming that it disproves AGW, or at least makes it a 50/50 proposition.
Your comment falls firmly in this tradition, if unintentionally. The scientist's response to seeing a crazy outlier isn't to immediately fall into spin mode; it's to go, wow, that's weird, what's the strongest explanation?
It's akin to someone posting about an awesome new discovery at CERN about the standard model, and then someone else jumping in and going "well the Standard Model doesn't explain X perfectly, so this is just a conspiracy." It's unproductive and toxic to scientific discourse.
