Sea Level Rise; A Major Non-Existent Threat Exploited by Alarmists and Politicians

• By Dr. Tim Ball Watts Up With That?

I know there are many articles on this website about sea level, none better than the recent one by David Middleton that speaks about "More nonsense about sea level rise." I thought his article would make the continuance of this article unnecessary. It doesn't because it is written for the WUWT readers. Unfortunately, too many of them like most of the public, scientists, and media don't know what is involved in creating the net result that is sea level. I think because they don't know, that it is time for something more basic as a citizen's template for fighting city hall. Citizens of Honolulu are the most recent victims of this as the Mayor of Honolulu directs the City to prepare for a 3-foot sea level rise in some undetermined time period. It was reinforced during a recent radio interview when a caller asked about it because his city was planning to spend millions on structures to anticipate sea level rise. I provided a few facts about changes in sea level, scientifically called eustasy, and all the other mechanisms that could explain that change.

Let's start with the automatic assumption by the public and the media that any major environmental issue, like global warming, glaciers melting, or sea level rising, is due to human activity. It reflects that bias, but also how little they know about all the natural causes of change. The simple assumption is that sea level rise is due to anthropogenic global warming (AGW) causing increased melting of glaciers adding more water to the oceans. In reality, just as with climate change, there is a multitude of causes, and few people know very little about any of them, and even those that do know have a quite limited understanding. As one group of scientists explained;

"a wide range of explanations for the current observed rise in sea level is possible."

In 1997, before it sold out to sensationalism to survive as a science journal for the public, Scientific American, took a reasoned look at the issue. Figure 1 shows the cover story.
