I'm glad to see this paper finally come out. It reports the first interpretation of 120-year-long polar motion data by considering a suite of processes operating at the deep interior of the Earth to its surface. nature.com/articles/s4156…

The paper underwent a roller-coaster ride in the review process, including rejection and appeal. Kudos to Mostafa Shahvandi, an ETH Zurich Ph.D. student (& a rising star!), for leading this effort diligently. Thanks to Prof. Dumberry (University of Alberta), Benedikt Soja, & others. Cc: NASA JPL

Backstory: Mostafa contacted me 2 yr ago asking if I'd be interested in mentoring him to do "impactful" science in the field of Earth's rotation. I told him there is no unifying explanation of polar motion data, hence the paper! That said, all coauthors contributed significantly!

In a new paper, we show that ongoing climate change is unprecedentedly altering the Earth's oblateness, causing its length of day to increase. Climate change could surpass the contribution from the Earth-Moon dynamics to become the leading driver of LOD. pnas.org/doi/10.1073/pn…

It is a testament to the gravity of ongoing climate change and its planetary-scale impact! NASA JPL ETH Zurich University of Alberta

It's not just in your head: A new study shows that days are getting longer – and the change is accelerating. In recent decades, faster melting of ice sheets has shifted mass from the poles toward the equatorial ocean, causing Earth's rotation to slow. go.nasa.gov/46taJKp

Thanks Andrew Wang for this well-crafted story!

As climate change melts polar glaciers and the sea level rises, mass moves from Earth’s polar to equatorial regions, increasing the planet’s oblateness—and making days longer. A day today is ~1.3 milliseconds longer than a day in 2000. In PNAS: ow.ly/rSeP50SFAUj
