that was very informative. If his facts are factual, it seems there are some issues with what has been used as "data" to perpetuate this. I'll be interested to hear the opposing viewpoints WITH LINKS to this.
It's a mixed bag. Some of the things Tony Heller says are quite true.

I don't think there's any one source out there that I completely trust on climate science. I think there's some bias on both sides of the issue. So, don't trust anybody completely is my advice (including me, I don't claim to be any expert on this topic). But, I think temperatures are getting warmer and I think we humans and our CO2 emissions are responsible for at least some of that increase. Why that doesn't appear to be affecting sea levels, I don't know, but I think Tony is right that we are not really seeing that effect in sea level data for some reason.
Tony doesn’t appear to have learnt from his mistakes, despite his scientific and technological background. Back more than a decade ago he was using selective data and simplistic analyses based on a poor understanding – and somehow thinking this allowed him to correct the experts. He is still doing the same.
Measuring "sea level" is problematic. It is commonly believed that oceans are like the water in your bathtub, nice and flat. When you add water, the ring around the tub rises at the same rate. This is a misconception. There are many influences on sea level: distance from the equator (centripetal force), proximity to large land or ice masses (gravity), winds and currents.In some places the shoreline is subsiding while in others it is uplifting...you begin to get the idea, but the ocean is not a bathtub.
One of the key points in the video in the OP of this thread is that sea level rise is not being influenced by human activity.

We also have satellite measurements of sea level. Very accurate measurements which are not affected by changes in topography. These data also show an acceleration in the rate of sea level rise. The average acceleration is not great, which doesn't make it obvious, and the signal can be elusive but it is there. I have little doubt.

I can buy that, as I said I'm convinced temperatures are going up so I expect to see sea levels rise but the historical data just didn't show a correlation of sea level increase with CO2 increase, but as I said it may be a delayed correlation. That talks about just finding an initial detection of acceleration.
Although this research is impactful, the authors consider their findings to be just a first step. The 25-year record is just long enough to provide an initial detection of acceleration -- the results will become more robust as the Jason-3 and subsequent altimetry satellites lengthen the time series.
Look at this screenshot from the OP video at time index 5:00:
I've experienced this directly. Over the past five or six years the islands have been surrounded by an area of exceptionally warm water. As a result our tides have been significantly higher (both high and low tides).
The ones where I live. The Hawaiian islands. The eastern end of the chain, with its much younger islands, is subsiding somewhat rapidly. The others, not so much.
What islands are you talking about?
