Melting Polar Ice Caps Slows Down Earth’s Rotation Making Days Longer, Messes with Global UTC Time

Ғылым және технология

We know that ongoing acceleration of global warming is melting polar ice caps more quickly.
When the polar ice (located close to the Earth’s axis of rotation) melts, the meltwater distributes over the global oceans, raising sea levels but also increasing the so-called Moment of Inertia (I) of the Earth system (sorry to remind you of your high school physics).
Since Angular Momentum (L) is conserved, and we calculate L = I times omega, as I increases then omega (angular frequency of Earth, which is tangential velocity times distance to axis of rotation) must decrease. Thus, melting polar ice caps slows down Earth’s rotation rate.
This slowing down makes days longer, and we must compensate our global timekeeping of Coordinated Universal Time (UTC) by periodic discontinuous additions of “one leap second” every few years. Because of accelerated ice melt, we will need to remove “one leap second” in 2029; 3 years later than would be needed if polar ice melt was not accelerating.
Climate change really does have profound effects on our planet.
Why the figure skater? Well, we are like her when her arms and legs are tight to her body axis of spin. Melting polar ice caps is putting mass further from the spin axis, analogous to her putting her arms and a leg outward, slowing down the spin rate, making a complete revolution take longer.

    One night more than 10 years ago, this topic was brought up over dinner. My friends thought I was going crazy and dismissed my attempt to describe the physics covered in this video. This prediction on the impact to Earth rotation, due to change in the ice cap mass, was made more than a decade ago. Nature is amazing. Only I wished that more people would have respected her and perhaps we wouldn't in the mess we are in now. Only if......

    Hi Paul, not sure if this counts as a social media channel, but you might consider putting the audio of your videos as a podcast. (This is something that someone like Nate Hagens does with his Great Simplification.) Lots of people listen to podcasts while on the go - it could be a great medium to reach a wider audience. Just a thought :)

    I can imagine that the redistribution of mass will also affect the earths magnetic field, continental drift and volcanism. We are messing with a system that has been relatively stable as long as humans and our cousins have existed. The unintended consequences will undoubtedly be dangerous to life on earth.

    The Earth has a fluid core, surrounded by a mostly solid "shell" (plates), awash by oceans of water. I can hardly wait to see what happens to the "shell" as the fluids interactively shift toward the equator. Oh, that's right, we live on the "shell."

    i read somewhere that the North Pole magnetic drift is a result of the trillions of tons of ice mass that has melted and floated away. If i remember correctly and not imagining this memory, it was confirmed by the two satellites traveling in tandem that measure the Earths gravity and the North Pole Drift was calibrated to the estimated mass loss,... am i crazy?

    This is an interesting symptom / outcome, however it's the kind of thing that would be used by a climate denialist or someone who want to minimalize or ignore climate change to say... Meh, that's not so bad. Just like telling them sea-levels could be 3 meters higher by 2100. It's a point by which to shrug and say... Hey, can we increase economic growth by another percentage point this year if we burn just a little more fossil fuels!?

    - We live in the same climate as it was 5 million years ago - I have an explanation regarding the cause of the climate change, it is the travel of the universe to the deep past since May 10, 2010. Each day starting May 10, 2010 takes us one thousand years to the past of the universe. Today April 01, 2024 the state of our universe is the same as it was 5 million and 75 thousand years ago. On january 20, 2050 the state of our universe will be at the point 14 million and 500 thousand years in the past. On september 15, 2100 the state of our universe will be at the point 33 million years in the past. Mohamed BOUHAMIDA.
