Bummer: ‘Climate Change” Caused Earth To Slow By A Whopping 1.7 Milliseconds In 100 Years

This obviously means total doom is soon coming, because you have your schedule completely thrown off. It’s as bad as a 1.4 increase since 1850!

Climate Change decreased Earth’s Spin Speed – El Paso Daily Science

Scientists are examing histroical changes in sea level in order to make accurate future predictions of this consequence of climate change, and they’re looking down to Earth’s core to do so. “In order to fully understand the sea-level change that has occurred in the past century, we need to understand the dynamics of the flow in Earth’s core”

The connection is through the change in the speed of Earth’s rotation. Melt water from glaciers not only causes sea-level rise, but also shifts mass from the pole to the equator, which slows down the rotation. (Picture the Earth as a spinning figure skater. The skater moves his or her arms in to spin more quickly or out to slow down.) The gravity pull from the Moon also contributes to the slow down, acting a little like a leaver break. However, the combination of these effects is not enough to explain the observations of the slowing down of Earth’s rotation: a contribution from Earth’s core must be added.

One of only a few people in the world investigating changes in Earth rotation, Dumberry contributed his expertise on Earth’s core-mantle coupling to the study. “Over the past 3000 years, the core of the Earth has been speeding up a little, and the mantle-crust on which we stand is slowing down.” As a consequence of Earth rotating more slowly, the length of our days is slowly increasing. In fact, a century from now, the length of a day will increase by 1.7 milliseconds. This may not seem like much, but Dumberry notes that this is a cumulative effect that adds up over time.

That’s the conclusion of a Harvard-led study published today in Science Advances. According to the authors, shrinking glaciers are affecting both the rotation rate and axial tilt of the Earth, by redistributing all that once-frozen water around the world. As water shifts from poles toward the equator, our planet’s midsection is becoming a wee bit wider. And that extra girth is causing the Earth to brake—in the same way that a spinning skater can slow herself down by sticking her arms out.

The study goes on to scaremonger about a potential 5 millisecond increase in your day from the slowdown by 2100. Of course, this is all based on computer models.

Nor does any of it prove anthropogenic causation. Why? Because they can’t. But, they are good at this doomsaying schtick.
