Earth’s rotation will slow down this century.
And the reason behind is is both fascinating and weird.
As ice caps melt, Earth’s rotation is slowing down, and that’s making our days slightly longer.
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.
huh, and I just thought it was the terrible global warming jokes from the comments that made the days seem longer:
The authors calculate that a day on Earth has already become a millisecond longer over the past century. And we could be in for another five milliseconds of day length by 2100.
So what about gravitation between the Earth and the Moon? And the Earth core rotation?
Well, now make the most of these precious extra fractions of fractions of time. Because nobody else will notice a damn thing.

If this is correct. The current cooling and record polar ice should speed up the earths rotation.
