Days growing longer

Scientists have discovered that days are growing slightly longer due to melting polar ice. As water moves away from the poles and towards lower latitudes, it changes the continental mass distribution on Earth, ultimately affecting our planet’s rotation.

The days go longer till the solstice and then they grow shorter

Once the days begin to grow shorter, polar ice increases

The nights are getting longer too. You should be well rested. ;=)

The article claims “a few milliseconds per year”. A millisecond is one thousandth of a second. That means one second in 1000 days, one second in three years. This should be measurable, but no actual data is presented. This is as much crap as the climate apocalypse predicted every year for the past 50 years.

From Livescience.com:

“ Spinning slower

Earth’s days have always varied in length. Around 1 billion years ago, our planet likely took only 19 hours to complete a single rotation, before slowing to the 24 hours we experience today.

It also changes on shorter timescales. For example, in 2020, Earth was spinning more quickly than at any point since records began in 1960. In 2021, the planet’s rotation began to slow down again even though we experienced the shortest-ever recorded day in June 2022.

But in general, Earth’s rotation has been slowing for millennia, mainly due to a process known as lunar tidal friction, in which the moon’s gravitational effect on our oceans pulls water away from the poles. At the moment, this effect is lengthening our days by around 2.3 milliseconds every century.

The new studies show that climate change is currently lengthening our days by around 1.3 milliseconds every century. However, based on current global temperature models, the researchers predict that this could increase to 2.6 milliseconds per century by the end of the 21st century, which would make climate change the biggest influence on our planet’s spin.”

Apparently there is no consensus. I will, however, accept a $9.9 million grant to study it.

Ocean levels should rise if it really is getting warmer.

[Democrat = party of treason]

LOL!!!

[Omnivore-Dan]

Right? According to Al Gore, N.Y. is supposed to be under water by now.

At least the sky isn’t falling ... oh wait, maybe it is.

Yes the length of a day has increased by (IIRC) a couple of milliseconds. Certainly measureable, but nothing of any practical consequence. This is in addition to the increase in length of day that is caused by the moon’s tidal friction (also around the same magnitude).

The new effect is caused by an increase in the earth’s rotational inertia about its axis of rotation. Moving mass further from the axis of rotation increases rotational inertia. Without an increase in angular momentum the result is a slower rotational speed. Angular momentum is equal to rotational speed x rotational inertia (analogous to the formula mass x speed for linear momentum). Angular momentum is conserved and no other body is involved. Therefore increasing inertia decreases speed.

This is a bit different than the other effect slowing the earth’s rotation. The tidal friction of the moon actually does reduce the angular momentum of the earth. Since angular momentum is conserved there must be a corresponding increase in angular momentum. This comes from an increase in the moon’s orbital angular momentum - the moon is getting farther away from earth. Again it’s a measureable effect but too small to have any practical significance.

Maybe on every other Windsday everyone in the northern hemisphere could fly a kite while shooting west.

If that doesnt work we could wrap a long string around the earth a couple of times, tie Hillary to one end and accelerate that end toward the sun.

Im setting up a charity to get aggressive on these things so please send me your cash. Dig deep, the children are depending on you.

Global warming is so bad I haven’t seen a penguin in the wild in Canada last time I drove to BC. We are doomed. K

The earth’s rotation is slowing and has been for millions of years. However, the rate of change is so small that it will be thousands of years before we have to reset the minute hand on our clocks.
