Huh?
“Earth is spinning faster than it used to. Clocks might have to skip a second to keep up.”

The story two threads above this on says the earth’s rotation is getting faster. I guess they have it covered. /s
“Earth is spinning faster than it used to. Clocks might have to skip a second to keep up.”
Earlier post.
So which is it?
Someone will have to show me the physics on this. Melting ice still maintains the same mass, and therefore the same angular momentum. The Earth’s rotational velocity should not be affected.
What is the mechanism for slowing or accelerating rotation?
Global warming and climate change also increase snowshoe accidents and cause excessive ear wax formation. (heavy sarcasm)
OMG! We’re all gonna die….its just gonna take a little longer now.
Other story:
Earth is spinning faster than it used to. Clocks might have to skip a second to keep up. (CBS)

Reality: The rotation of the Earth speeds up and slows down by small amounts all the time. This is not a new discovery or in any way disputed.
Isn’t there a CBS story about three threads up that says just the opposite? So, CC is making the earth spin faster at CBS and slower at NBC. I guess we need to wait for ABC to break the tie.
NBC says Earth is slowing. CBS says it going Faster. Fake News @ it’s Best.

or
Melting polar ice is slowing the Earth's rotation, with possible consequences for timekeeping
Sure it is. 🙄
Yet CBS says the earth is spinning faster due to global warming.
Competing Communist Broadcasting stories.
Wait just one moment; Just read a Scientific Article that in five years Atomic Clocks will have to be adjusted one second because the earth is spinning faster. Who has been smoking what?
Wikipedia says there were five major ice ages. Makes me wonder what warmed the Earth in between. No cow flatulence, no SUVs, no coal-fired plants.
I’ll finally get to use the speed adjustment on my clock?!
I predict there will be numerous terror attacks in the US before any of Obama’s waterfront mansions are flooded.
CBS says earth is spinning faster and NBC says it’s going slower! Could they just make up their minds before they tr to sell us a bag of baloney?!?!

A global timekeeping problem postponed by global warming
Duncan Carr Agnew
Nature volume 628, pages333–336 (2024)
Abstract
The historical association of time with the rotation of Earth has meant that Coordinated Universal Time (UTC) closely follows this rotation1. Because the rotation rate is not constant, UTC contains discontinuities (leap seconds), which complicates its use in computer networks2. Since 1972, all UTC discontinuities have required that a leap second be added3. Here we show that increased melting of ice in Greenland and Antarctica, measured by satellite gravity4,5, has decreased the angular velocity of Earth more rapidly than before. Removing this effect from the observed angular velocity shows that since 1972, the angular velocity of the liquid core of Earth has been decreasing at a constant rate that has steadily increased the angular velocity of the rest of the Earth. Extrapolating the trends for the core and other relevant phenomena to predict future Earth orientation shows that UTC as now defined will require a negative discontinuity by 2029. This will pose an unprecedented problem for computer network timing and may require changes in UTC to be made earlier than is planned. If polar ice melting had not recently accelerated, this problem would occur 3 years earlier: global warming is already affecting global timekeeping.
