The Ocean Floor Is Sinking Under The Water Weight From Melting Glaciers, And It’s As Bad As It Sounds



Hat Tip: Weasel Zippers

The following article appeared in Newsweek on January 7th


So much extra water is being added into the world’s oceans from melting glaciers that the ocean floor is sinking underneath its increasing weight. This ocean floor deformation also means we have miscalculated just how much ocean levels are rising and the problem could be far worse than previously believed.

Over the past 20 years, ocean basins have sunk an average of 0.004 inches per year. This means that the ocean is 0.08 inches deeper than it was two decades ago. While this small fragment of an inch may not seem much, oceans cover 70 percent of our planet, making the problem bigger than it seems at an initial glance.

In a study published online in Geophysical Research Levels, researchers explain how they used a mathematical equation known as the elastic sea level equation to more accurately measure the ocean floor. This allowed them to see how much the bottom of the ocean floor has changed from 1993 to 2014. While they are not the first scientists to look at the ocean floor, this is the first time that researchers have taken into account how additional water from melted ice may have further stretched the ocean floor, LiveScience reported.

The results show that the ocean is changing in ways that we previously did not realize and is sinking further into the earth’s crust. As a result, scientists have underestimated how much sea levels are rising by as much as 8 percent. The study concludes by emphasizing that future sea level measurement should take ocean floor deformation into account in order to more accurately understand how our oceans are changing.

All the water on the planet today is all the water that has ever existed on the planet, but not all water is in its liquid form. Recently, rising temperatures have caused much of the frozen water on the planet’s glaciers to melt and join the ocean as liquid. This mass melting ice rising sea levels, a problem whose consequences we’re already starting to see. The first to notice the repercussions of rising sea levels are those who live in coastal areas. Rising waters mean less land to live on. In addition, more water in the ocean means that ocean storms, such as hurricanes, have the potential to be stronger and more devastating, National Geographic reported.

Small coastal areas won’t be the only ones to disappear due to rising waters and if current estimates are correct, by 2100 the ocean will rise between 11 and 38 inches, a number that could mean that much of the U.S. east coast will be covered in water, National Geographic reported. 


Ed.  If this means San Francisco will soon be underwater, I'm all for it.

  1. Perhaps the dumbest bit of junk science in a while.

    Any ice floating will add nothing to water levels or weight (look up law of displacement).

    Any land melting ice that has added what they claim as an inch in ocean level would increase the pressure at the bottom of the ocean. Want to know how much?

    Water pressure increases one "atmosphere" (the weight of the atmosphere at sea level 14.6 PSI) for every 10 meters of ocean water depth. 10 meters = 393.7 inches. So if man made global warming has added 1 inch to the ocean as claimed, 14.6 PSI divided by 393.7 gives us a whopping pressure increase on the oceans bottom of 0.037 PSI! (I rounded up).

    This is the same as a unit of measure used called "water column" which is the pressure (or vacuum) created by a theoretical 1 inch square tube filled with water and is considered to convert to....0.036 PSI! Think of it this way the average depth of the ocean is 12,800 ft, if you had the mentioned tube that long filled with water the pressure would be huge at the bottom (it would rupture). How much does adding one more inch increase that? (calculation above).

    It's amazing how ignorant these people truly are.

    1. @ D Gray,

      The environmentalist, whacko left have no interest in fact, truth, science or any of that icky, difficult-to-understand stuff.

      The interests of this group can be divided into: 1) the pursuit of money, as in government research grants (after all, some scientist--whether real of phony--will never be awarded a bunch of dough if he concludes that there is NO threat from global warming); and 2)the desire to destroy American business, capitalism, free enterprise--all of which represent the bane of Marxist purity.

      Thanks very much for your comment.
