This information comes from:

“Global mean sea level has risen about 8–9 inches (21–24 centimeters) since 1880, with about a third of that coming in just the last two and a half decades. The rising water level is mostly due to a combination of meltwater from glaciers and ice sheets and thermal expansion of seawater as it warms. In 2019, global mean sea level was 3.4 inches (87.6 millimeters) above the 1993 average—the highest annual average in the satellite record (1993-present). From 2018 to 2019, global sea level rose 0.24 inches (6.1 millimeters).”

So, in short, if you read this, then you have some professional information. But if you talk to critics about this information, and you decide the critics are right, please be sure they have documents, valid peer reviewed information, and qualifications that show their own interpretation is based on unbiased agendas. Sadly, more and more are getting paid blood money to spread miss information for obvious reasons.
