Rising Tides: Apparent and Actual Sea Level Rise in Miami Beach

First, the Apparent Sea Level Rise

More than 80 percent of known land subsidence in the U.S. is a consequence of groundwater use, and is an often overlooked environmental consequence of our land and water-use practices. Increasing land development threatens to exacerbate existing land-subsidence problems and initiate new ones. Subsidence detection and mapping done by the USGS is needed to understand and manage our current and future land and water resources in areas where subsidence is a problem or may be in the future.

Over the past decade, several coastal communities in southeast Florida have experienced a significant increase in flooding frequency…The increased flooding frequency reflects the contribution of global, regional, and local processes that affect elevation difference between coastal communities and rising sea level…These results suggest that contribution of local land subsidence affect only small areas along the southeast Florida coast, but in those areas coastal flooding hazard is significantly higher compared to non-subsiding areas.

…on the coast of the U.S., we can point to a phenomenon called post-glacial rebound. During the last Ice Age, parts of the northern hemisphere including present-day Canada and the northeast U.S. were covered by huge sheets of ice.

That ice was really heavy, and made the land underneath it sink down, which in turn made the land on the edges of the ice sheet rise up. When the ice sheets started melting, the land that had sunk down started to rebound and rise back up, while the areas that had risen up now started to sink. This rising and falling is still going on today, and the areas that are now slowly sinking are the most affected by rising sea levels.

Map of Western Antarctica

…the heat coming from beneath Antarctica is constrained to 150 milliwatts per square meter, with a higher heat rate causing too much melting as compared to what is measured. To compare that with other areas, the average heat flux from the Earth is 40-60 milliwatts per square meter and it reaches an average of 200 milliwatts beneath Yellowstone National Park.

Question: What is the source of the heat under western Antarctica?

In comparison, the Sun’s photosphere has an estimated temperature of 5,538 °C (10,000 °F). The heat beneath Antarctica is the natural heat of the earth itself. The sun is, on average, about 93,000,000 (million) miles distant. The core of the earth is merely 4,000 miles from the surface of the earth. We all know how the heat of the sun affects our lives. What do you know about the Earth beneath your feet?

Rest easy, when you fill up your car with Diesel or gasoline. Do not fret over the smoke from your BBQ grill. Youl are not causing glaciers to melt.

Environmental activists hypocritically bemoan your “carbon footprint” while jetsetting around the world to spread their false narrative of climate doom due to human activity.

In passing, it will be helpful to understand how the rabid environmentalists attribute the melting of the so-called ‘doomsday glacier’ atop western Antarctica to anthropogenic (man-caused) activity. Reference: YouTube video titled The Doomsday Glacier Is Collapsing…Who Is Most at Risk?

If God so chooses to melt the ice on Antarctica, who am I to argue with Him? To be sure, all the king’s horses and all the king’s men will never be able to keep that ice from melting.

You who may doubt God’s ability to melt glaciers, cause draughts, spawn hurricanes, unleash volcanoes and earthquakes, I recommend a book titled Eye to Eye: Facing the Consequences of Dividing Israel.

  1. Dear John

    Hello from the UK. Many thanks for your post.

    As regards ‘Environmental activists hypocritically bemoan your “carbon footprint” while jetsetting around the world to spread their false narrative of climate doom due to human activity.’ I whole-heartedly agree.

    I would add ‘…and ignore the far more pressing issue of pollution for example due to man’s greed and stupidity’.

    As regards ‘Rest easy, when you fill up your car with Diesel or gasoline…..You are not causing glaciers to melt.’ I agree, but with the proviso that diesel and gasoline are toxic and cause many health problems as a consequence. Including the fact that too many in the USA are too lazy to get off their backsides and walk or cycle, part of the increased obesity problems.

    Diesel is however, far worse than gasoline, but then it was invented by a German so this is sadly understandable. You may think this harsh on the Germans, but then Germany did start two world wars, excluding this current one, this war of words re Covid 19.

    Kind regards

    Please excuse the nom-de-plume, this is as much for fun as a riddle for people to solve if they wish.

    1. Thank you for your great comment.

      Socrates died of poisoning but he suggested a fine, instead.

      One element all on its own can seem undesirable until you evaluate the alternative.

      An interesting principle found in the Bible in Proverbs 14:4, “Where no oxen are, the crib is clean: but much increase is by the strength of the ox.”

      How well I remember the polluted skies over Pittsburgh, Pennsylvania and Birmingham, Alabama.

      The environmentalists got the skies cleared up and industries left the country. Birmingham, named after an English town, experienced high unemployment and poverty for many years.

      In this industrial age in which few work or live on farms, the energy of choices, for now, are Diesel and gasoline to get folks to and from work. My little Mercedes-Benz E300 Diesel actually makes no mess whatsoever and it’s fun to drive.
