New research has implications for how we keep track of time​

The Greenland ice sheet, the second largest body of ice in the world which covers roughly 80 percent of the country, has been melting and its glaciers retreating at an accelerated pace in recent years due to warmer temperatures. If all of that ice melts, sea levels will rise by several meters, though there will be regional differences. (AP Photo/David Goldman, File)

The Earth’s rotation isn’t always constant, leading to the need for adjustments in our clocks. Recent satellite measurements reveal that the Earth’s rotation is slowing down faster than before due to melting ice in places like Greenland and Antarctica.

This slowdown affects the Earth’s core and its overall rotation speed.

A new scientific paper highlighted how these changes complicate our timekeeping system called Coordinated Universal Time (UTC), especially in the face of climate change.
Since 1972, timekeepers have had to add “leap seconds” 27 times to keep up with the pace. However, there may be a need to reduce leap seconds in the coming years as the Earth slows from various factors, including the redistribution of mass and influences by the planet’s axial wobble.

The moon is known to slow the Earth’s rotation since it is receding from Earth about 1.49 inches per year.

But new research using satellite measurements shows melting ice, particularly from regions like the Canadian Arctic and Fennoscandia, affects the Earth’s rotation in multiple ways. When ice melts from polar regions, water is redistributed, causing shifts in the Earth’s mass distribution, and impacting its rotation.

According to Duncan Carr Agnew, the report’s author, if these trends continue, significant changes to UTC may be necessary by 2029 due to the Earth’s slowing spin. This highlights how global warming not only impacts the environment but also affects our timekeeping systems.

Time is not a constant, but a variable, and depends entirely on the frame of reference of the observer.

Am I the only one that read the Theory of Relativity?
 

🤔......so....good news for people with vertigo then!?

Oh how I wish.....if only..

Vertigo is a disagreement between your inner ear and the vestibular nerve from that ear to the brain. The vertigo is the brain having a hissy fit trying to make sense of the gibberish the inner ear is telling it.

As one who has experienced it far too many times, vertigo sucks beyond description...

So, that said, the short answer is NO, the Earth is still spinning around 1,000 mph., so losing a millisecond won't make a bit of difference.
 

Now, correct me if I am wrong, but I think the melting of ice has happened before, narrowing it done to the last several million years, and there have been a couple of re-freezes? perhaps? If the earth's rotation IS slowing down, all I know that on my level, being in my 70's, is that time seems to be really speeding up!
 

The Earth probably is slowing down, but it is a natural thing. The scientist are just finding this out and they need to blame something. There are also cycles that come and go over the eons. As far as time goes man has only been here a couple of seconds and already he knows everything!

Sounds like Ex wife syndrone!

Sorry to hear you have it, must drive you mad.

Yeah, that was my dry Aus humour. It falls flat quite often. Sorry it offended.
I'll dial it back 👍
 

No worries Chilli...not offended in any way...:icon_thumright:

I have Meniere's Disease, and vertigo is just part of the "benefits" it brings.
 

So your post is very interesting. The local paper in yesterday's edition had an article about how the trend had been for the earths rotation to slow, but in reality over the last few years it has actually sped up to the point they believe in about 5 years they will have to do a "skip second" to get back in sync.
 

The cult of Henny penny the sky is falling in.

Panic sells. Panic gets funding for other wise useless departments in universities. All part of the panic industry they have infiltrated the science industry creating confirmational bias.

Its the you beaut excuse for everything! I did not pay my taxes. its global warming. I beat my wife blame global warming. I got drunk and fell over. Global warming I robbed a seven eleven. The effect of global warming.

Well we will have more kids super gluing themselves to the road. And few more kids with mental breakdowns and killing themselves.

Some of us old farts are old enough to remember the very same universities selling this same crap in the 1970's except it was not global warming? it was ice age. when they did not appear to happen. They switched to global warming.

Are they the universities and the media ever going to put their hand up and take responsibly for promoting this doomsday cult that is responsible thousand of suicides around the world.

It's easy to blame the Earth's rotation slowdown on climate change, but the rotation has been slowing for billions of years.


For billions of years, Earth’s rotation has been gradually slowing down. It’s a process that continues to this day, and estimates suggest that the length of a day currently increases by about 1.8 milliseconds every century. The day's length varies slightly from year to year, as well; the result of myriad forces both on and off Earth pushing and pulling at its rotation.
 

Losing the time was never a problem...it was figuring out where I was at, where my clothes were, and who that naked girl was sleeping beside me!

my case was waking next a BEAUTIFUL girl that I saw through my beer goggles the night before turned out to be as ugly as a hat full of ass holes!

My problem was I lost time and the naked girl beside me let me know that I wandered out buck naked sleepwalking for an hour or so in the middle of the night....right in the center of town as well. Still wonder to this day what I was up to, and how I wasn't arrested and put on a list, and how I found my way back to her bed after all of that.
