Earth's Inner Core May Be Tugging the Mantle, Changing Day Length by Milliseconds
Inner core gravitational torque, shaped by a 10-year viscous lag, reproduces Earth's multidecadal day-length changes from 1964 to 2019, Nature reports.

Trapped Gases Suggest a Famous 2-Billion-Year-Old Carbon Signal Was Local
Trapped gases from Karelia's Zaonega Formation show a 72-350°C gradient beside a 2-billion-year-old magma sill, reframing a global carbon signal as local.
Why Some Tilted Hurricanes Quickly Align, and Others Stay Leaning
New analysis of 1,510 NOAA Hurricane Hunter radar scans reveals why some tilted tropical cyclones quickly align vertically while others stay leaning and weak.
Storms Bury the Atacama Desert in Snow, Dump Ten Times Normal Rain on the Coast
Back-to-back storms buried Chile's Atacama Desert in snow, halted the ALMA telescope, and dumped 10x normal rain on Taltal amid a strengthening El Niño.
Ship Data Show Iodine and Sulfur Chemistry Seeding Arctic Clouds
A five-week Greenland ship campaign found iodine and sulfur acids seeding Arctic particles, then organic vapors grew them into far more cloud-seeding nuclei.
