And yet the frequency of floods has increased in the past decade due to high tide events, e.g. rising oceans waters.

Miami Beach tide gauge readings haven't changed since the year that study was published.

Also, do you really find that study credible? "tide-induced events increased by more than 400%" in one single year? Sea level rise is a slow and steady process, but these guys are claiming it tripled in the span of a single year. That hasn't been reported anywhere else.

The plot you posted shows a clear growth over the last 20 years.

I just looked for a local study. In either case, South Florida just this year had "once in 100 year" floods. At this point I would need studies to prove climate change isn't a key driver.

Yes, but that's not what I said. Sea levels do rise globally at a slow rate, but it can also be offset by the land itself rising and falling (isostatic rebound), by minor changes to instruments (because the actual changes we're talking about are tiny), temperature changes affecting the volume of the ocean etc.

In that particular city and beach, you can see that tides went down between 2000-2005, then remained more or less stable until 2015, then went up a bit and stabilized at a new level. CO2 levels meanwhile go up very steadily. This data clearly doesn't indicate something CO2 driven given the various trends including declines that have happened within the time since the gauge opened in 1995. These look like natural changes, which are expected because especially when zoomed into these tiny differences everything is always changing.

If they happen every 100 years then why is human CO2 emissions to blame? Even climatologists don't claim there was much CO2 impact in 1920 or 1820.
