tens of thousands of people took fossil fueled trips from all over the world to Paris to yammer on about how bad fossil fuels are and force their far left redistribution plans down your throat you drove a fossil fueled vehicle
Climate change means days are getting longer, scientists find
Duration of day has lengthened by a millisecond over the past 100 years as water from shrinking glaciers slows Earth’s rotation and shifts position of poles
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.
The research, published in Science Advances, apparently solved a scientific puzzle known as “Munk’s enigma”, which came from a 2002 researcher paper by oceanographer Walter Munk, examining how the melting of glaciers had altered the Earth’s rotation and axis.
Oh, dear Lord, a whole millisecond! We’re doomed! Nothing like this has ever happened before, surely! Unsurprisingly, this is based on lots and lots of assumptions and computer models. And, the article and study mostly avoids doing the blame game on fossil fuels. Not so over at Take Part
As pollution from burning fossil fuels continues to heat the atmosphere, the world’s glaciers are melting at an accelerating rate. Scientists widely agree that this meltwater has been a major factor in raising global sea levels about seven inches over the 20th century.
The movement of all that water is affecting the Earth’s rotation, according to a study published Friday in the journal Science.
“If you are melting glaciers from high latitudes—in Alaska, Greenland, or Iceland—you move mass away from the pole, toward the equator, which slows the Earth down,” said Jerry Mitrovica, the study’s lead author and a Harvard geophysicist who specializes in studying sea level change. “The change in the distribution of the mass from the poles to lower latitudes also causes the rotation to wobble slightly, because it’s being redistributed unequally.”
Huh. A wobble because you took a fossil fueled trip to visit Grandma over Christmas. And, of course, they’re all saying that the Earth will slow down even more. It could be a couple milliseconds! It could throw everything out of whack!
But, um, remember when the Cult of Climastrology was claiming that Hotcoldwetdry was making the Earth speed up? So, which is it? Eh, it doesn’t matter. This is all about attempting to scare people, so, consistency of talking points is unnecessary. I’m just shocked that life on Earth survived all these millisecond changes during previous warm and cool periods.
