The impact of climate change may appear to be overwhelmingly negative but there is a bright spot for those who struggle to find enough time in the day: melting glaciers are causing the rotation of the Earth to slow thereby lengthening our days, new research has found.
Harvard University researchers have provided an answer to a long-held conundrum over how shrinking glaciers are affecting the rotation and axis of the Earth, calculating that the duration of a day has lengthened by a millisecond over the past 100 years.
The brakes will be more sharply applied to the Earth's rotation as glaciers melt at an ever faster rate, meaning that at least five milliseconds will be added to each day over the course of the 21st century. The axis of the Earth will shift too, with the north pole set to move position by about 1cm (o.4in) during this century.

Strange. I was always taught the opposite, that the days were actually getting shorter due to the earth slowly being pulled into the sun. That is why the human body “evolved” for a 25 hour a day schedule while there are now only 24 hours.
So the nights are getting shorter? Lol.

Those aren’t turbines, those are propellers that our Glorious Leader is going to use to fly the Earth to an orbit further out to counteract the warming caused by all of you deniers.
Nice try but the moon has more effect on the earth than the glaciers, and as the moon gets farther and farther away every year it is causing the earth to slow down.
The Moon causes ocean tides on Earth to bulge towards it. However, the Earth is rotating faster than the Moon orbits so the tidal bulge swings ahead of the Moons pull. The gravity of this off center bulge pulls the Moon to a higher orbit and in the process slows the Earth’s rotation a little.
Another consequence of the Moon being farther away is that it takes longer to orbit the Earth; the lunar month becomes longer. In the future, the maximum length of the day will be reached when the Earth rotates at the same speed that the Moon orbits. In other words, the day and the lunar month will have the exact same length, somewhere near 47 of our present 24-hour days. At this point, since the tidal bulge will not be swinging ahead of the Moon’s orbit, the Moon will no longer be moving away but will remain in a stable orbit.

So.... does that mean that women’s menstruation periods will occur every 47 days ?
The reduced mass of the glaciers is speeding up the planet rotation, but I guess the increased mass of all the new trees and people aren’t slowing the planet. As if glaciation is the only thing changing mass on earth.
Talk about cherry picking.
People, trees and glaciers do not change the mass of the earth, only the distribution. The mass is increasing because of meteor impacts, to the tune of a few tons a day.
It’s MUCH more dire than that! It’ll only take 1,000 years, not 100,000 years. The time to act is NOW! There’s no time to wait. We cannot afford the risk of inaction.
seriously? Seems to that if you apply the same principles that make an ice skater spin faster as she draws her arms in, then you would conclude that the Earth would start rotating faster, if anything, because ice has more volume than the same mass of water, and a lot of the ice is on land and so above sea level. When it melts, the volume will shrink and the resulting water will move closer to the center of the Earth. In other words, the mass of the Earth will, if anything, move closer to the axis of rotation, meaning that like the ice skater, the Earth will rotate faster, not slower. If you buy into the nonsense that there is sufficient ice to materially alter the Earth’s rotational speed at all.
If climate change (global warming) can cause terrorism, it could also cause my uncle Donald to become my aunt Donna, right?

No wonder folks buy that 40 PPM CO2 crap!
One millisecond = 10-3 second.
That's .001 second...
So somehow the mass or total weight changes? Really? We are losing water weight into space!? We are doomed, doomed I tell you!
I just wish all the global warming idjits would crawl under a rock and die.
The SUN drives our climate, nothing else. Idjits.
I would like to millisecond them.
Which means that the mass of the melted ice would shift from farther from the center of the earth to sea level, and that should have the effect of slightly increasing the rate of rotation, not decreasing it. demonstration
Why? Because (ultimately) less CO2 is being emitted. You'd think that would make those people happy.
Added benefit is that the longer things are growing, the more CO2 they take in.
See?
Warming is good for the planet!
“meaning that at least five milliseconds will be added to each day over the course of the 21st century. “
Someone check my math -
so over 100 years (rounding from now to year 2100), .005 seconds is added
so it will take 1200 of those 100 years to mean 1 minute added to each day
that means 1,200,000 years to get 1 additional minute.
I better get a new watch then, LOL
Assuming all this crap is true
It is certainly excellent for my part of it. And, to be honest, the rest of the planet can fend for itself. Refugees from "the global warming disaster" have to fly to get to me. We have an air force.
Silly me. I plumb forgot that the components of the earth come from the building blocks of the earth and that matter can’t be created. Yep, silly...
