High Tides

From left, Joanie Sanders, Reagan Litts and Hannah Harp walk across a tide-flooded parking lot on their way to Stewart Beach in Galveston on Tuesday, May 21, 2019.

A change in the moon’s orbit, along with rising sea levels, will lead to increased flooding in coastal cities like Galveston, according to a NASA study.

The study, published in the journal Nature Climate Change, showed a natural shift in the moon’s “wobble” as it orbits Earth will lead to higher tides.

It's useful to have a historical graph to show the changes over time. The chart from NOAA's media release is here:

The graph shows the median number of high-tide events per year for coastal communities as well as sea levels for the past 100 years.

Thanks, I hope people read and learn

Sea level has increased 400 ft since the end of the last "ice age"12,000 years ago. Humans and wildlife coped with it by moving back from the beach an inch or two per year. Sea level rise is slowing because it takes more water to increase the level of a bigger ocean.
