The smaller animal migrations in Africa, ice melt, and the Three Gorges Dam are massive enough phenomena to affect Earth's rotation speed.

Jesus Fark Christ, really?

Nothing is metronomically perfect.  Everything sloshes a bit.  There is a reason every measurement has a farking error bar.  That the Earth doesn't behave perfectly over days, week, months, years, or even decades means not a tinker's damn considering the planet is 4+ billion years.  It is well worth trying to figure out what is causing the inconsistency to improve models, but these idiots writing "Waily, waily waily!  We all gunna DIE!" articles based on "the measurement was .00000000000004 picoseconds from yesterday" need to be yeeted right off the planet - but not at escape velocity, because at least they will serve some scientific purpose when astronomers watch them reenter the atmosphere.

Education time! Plants make up 82% of all biomass on earth. Scientists use gigatons of carbon (dont ask me why, i have no idea), but the number they give plants is 450 GtC (gigatons of carbon). Bacteria are the next largest group, with 70 GtC. Following them, you have Fungi (12 GtC), Archea, which are like bacteria but no nucleus (7 GtC), Protists, which are more complex than bacteria but still single cell (4GtC), and then you have ALL ANIMALS ON EARTH (2.589 GtC).

Animals break down as follows (in GtC):

Arthropods (Marine) 1.0
Fish 0.727.0%
Arthropods (Terrestrial) 0.2
Annelids 0.2
Mollusks 0.2
Livestock 0.1
Cnidarians 0.1
Humans 0.06
Nematodes 0.02
Wild mammals 0.007
Wild birds 0.002

Oh crap, sorry sorry, I forgot. Viruses are .2 GtC, so they are above livestock, all terrestrial mammals, all birds, all worms, and all aquatic invertebrates.

What the fark makes you think animals migrating in africa has any farking impact on the planets rotational speed?

They are saying its overall, getting slower...not just random days.   And there was no panic in that article.  its must a matter of interest, because currently scientists don't know why it happening.

There's a disconnect between how scientific papers are written and accompanied by an abstract that the average layperson writer can understand, and how it's rewritten into an article that is intended for consumption by the average Sun reader.

Paper - Lots of math

Abstract - Something like "Since 1960, increasingly accurate measurements of the Earth's rotational period have been made and some anomalies have been discovered, the reasons for which are not completely clear. There are a number of possible explanations for this, including shifts in the Earth's magnetic field affecting the speed of rotation in the core, sunlight pressure on larger amounts of clouds coming from climate change, an imbalance in the simultaneously repulsive and 'kinda want' forces of Lisa Appleton and many other factors."

Article - Scientists have NO IDEA what's causing the Earth's days to get longer! We're going to talk down to you for a bit and explain some obviously basic science. Wow isn't this watered-down shiat kind of interesting?

The Sun - EARTH'S DAYS ARE GETTING LONGER - ETERNAL SUNLIGHT POSSIBLE...SCIENTISTS BAFFLED!!! Now see NUDE PICS of hottie TILA TEQUILA leaked...steamy TIKTOK!!!

Tila Tequila - The Earth is flat but Hitler is making it rotate, and the Sun dies every night...but now I look like I've been living in a cave for 10 years.

So the point is, there's a lot of room for facts to fall until they're utterly unrecognizable garbage.

Anything with a mass that's gravitationally locked with the earth has a barycenter. Obviously the Sun and Moon are the major players. But you have one too with the Earth. I'm just saying the regular migration patterns of Africa's large animals has a negligible effect on the earth. Viruses and Plants don't do much unless you count forest depletion.

ecmoRandomNumbers: It's the sun's albedo, dummies!

(I have no idea what I'm talking about. I just wanted to say "albedo.")


I don't know if the sun has an albedo. It probably has some I guess, but IIRC albedo is a reflective quality and the sun doesn't have much to reflect, given that it's the only light source within about 4.22 light years.

It probably does reflect some of the light that gets reflected back onto it from other astronomical bodies, I suppose.

You'd expect them to speed the rotation rate up, I'd assume, since they should settle rock and lower the planet's moment of inertia, like how pulling in your arms while spinning on an office chair makes you go faster

I don't want her sobbing. After she cuts ties with "that stupid farking pimp," I want her disappointed for the rest of her life, as every partner - male, female, whatever - just isn't cutting it any more,

I want her wistful, a bit despondent, and to wax fondly about me in her tell-all memoir which incriminates at least four members of Congress, a foreign head of state, and an evangelist. Here's hoping she gave it a nickname.
