There’s a deeper conspiracy that you’re not a part of. Whatever the net effect of glacial melt or hydroelectric projects, the issue is not very easy to model, and in the end is mainly a lot to do about nothing terribly significant.

Or more specifically, how long does it take for the Earth to turn once on its axis?

It doesn’t make much difference to me in everyday life, although it does come into play when trying to explain to non-astronomy types why the stars don’t rise at the same time every day. ^_^;;Whether it actually works this way in the analog universe has proven extraordinarily hard to calculate/measure. Well, I’m here to tell you that you’re wrong too. Empirical dataThe length of the day can also be influenced by manmade structures. This means that a sidereal day is actually 0.0084 seconds shorter when you account for this extra movement of the Earth’s axis.There are other events that can increase or decrease the length of an Earth day. It only takes 23 hours, 56 minutes and 4.0916 seconds for the Earth to turn once its axis. However, due to Nabu’s* odd orbital characteristics, the solar day there actually lasts almost half an Earth year; you might have as much as four Terran months to figure out a plan to either follow the shade of night, or construct your own!Crazier still is the fact that at some points the orbital velocity & the spin rate of Mercury cause double sunrises & sunsets on the same day in some places, while in others the sun crosses directly overhead three separate times before slowly setting.

(cf.
For example, The primary monitoring of Earth's rotation is performed by Around every 25-30 years Earth's rotation slows temporarily by a few milliseconds per day, usually lasting around 5 years.

The earth’s rotation axis is tilted about 23.5° … Tell us in the comments below.The Earth is never in the same place twice because of the Corkscrew Effect, Thanks for the information Fraser and have a Great Day!…..Or is it?I’ve know the difference between a solar day and a sidereal day since I was a teenager, and I’m in my 50’s, so the whole bit about the reader stumbling about incoherently, etc., was more than a bit overblown. Imagine the Earth orbiting the Sun, taking a full 365 days, 5 hours, 48 minutes and 46 seconds to complete the entire journey.

Were you reprogrammed by the hidden chronology conspiracy? Aren’t you?

The length of the day can also be influenced by manmade structures. And More…Click to email this to a friend (Opens in new window) Madness. Luna then pulls much of this newly mobile mass to the tidal bulges closer to the equator (i.e., away from the axis of rotation), slowing things down.

2017 was the fourth consecutive year that Earth's rotation has slowed. And then ask if they’d like you to incorporate the Earth’s precession, tidal locking and recent earthquakes into the calculation. ^_^)Your ice skating example is a good way to look at it, but it actually tends to back what Fraser said. Researchers discovered this by studying the growth rings of ancient mollusk fossils.

That means future lunar inhabitants will have to get used to a sunlight "day" that lasts for about 14 Earth days and a … A single day on the Moon lasts the equivalent of 29.5 Earth days, which is the result of its tidally-locked orbit with Earth, and Earth's orbit around the Sun.

Just ask me. The water levels are way down because of a different Chinese dam project.When taking all of these hydroelectric projects world wide together, I come to the conclusion, that the rise of the land mass of Scandinavia, and the melting of glaciers, while significant, can not be used without considering the hydroelectric projects, to determine the rate of the earths rotation, and most computer models do not properly factor in the amount of hydro power generated electricity needed in the future, and its effects.I’ve mentioned in my comments on previous articles that the whole thing is like trying to figure out how much the top speed of a whale is affected by the amount/type of bacteria growing on its skin: the answer, regardless of net direction, is “NOT MUCH.” ^_^ Aside from your math which compares various volumes of material with unlike densities (water & ice do not weigh the same per unit volume)… is Switzerland the only place on Earth with glaciers?
