Significance Modern climate change is unprecedented. In recent decades, it has accelerated the melting of glaciers and polar ice sheets, leading to a rise in sea level. This pole-to-equator mass transport has significantly increased the Earth’s oblateness and length of day (LOD) since 1900. We show that the present rate of increase is higher than at any point in the 20th century. Under high emission scenarios, the climate-induced LOD rate will continue to increase and may reach a rate that is twice as large as at present, surpassing the impact of lunar tidal friction. These findings signify the unprecedented effect of climate change on planet Earth and have implications for precise timekeeping and space navigation, among others. Abstract The melting of ice sheets and global glaciers results in sea-level rise, a pole-to-equator mass transport increasing Earth’s oblateness and resulting in an increase in the length of day (LOD). Here, we use observations and reconstructions of mass variations at the Earth’s surface since 1900 to show that the climate-induced LOD trend hovered between 0.3 and 1.0 ms/cy in the 20th century, but has accelerated to 1.33 0.03 ms/cy since 2000. We further show that surface mass transport fully explains the accelerating trend in the Earth oblateness observed in the past three decades. We derive an independent measure of the decreasing LOD trend induced by Glacial Isostatic Adjustment (GIA) of 0.80 0.10 ms/cy, which provides a constraint for the mantle viscosity. The sum of this GIA rate and lunar tidal friction fully explains the secular LOD trend that is inferred from the eclipse record in the past three millennia prior to the onset of contemporary climate change. Projections of future climate warming under high emission scenarios suggest that the climate-induced LOD rate may reach 2.62 0.79 ms/cy by 2100, overtaking lunar tidal friction as the single most important contributor to the long-term LOD variations.

The strongest earthquake for Italy in ten years just struck outside of Naples near two of Italy's largest volcanoes, Campi Felgrei and Mt Vesuvius. At magnitude 6.0 and very deep at ~380 km, this seismic energy from this event spread out widely across all of Italy.

Today February 27, 2026 I found this particular Fish Fetish. Hand carved, shaped and polished from ancient, hard metamorphic rock. Marine sedimentary deposits transformed, morphed 😁 under high heat and pressure. I can see little tiny sparkly white bits of calcium carbonate, the remains of the Permian epoch mass extinction I suspect 🤔
Autistic me, OCD to the max about certain things, have found a nice collection of Fish Fetishes over the years, all in this upper Colorado and Gunnison river drainages Being a fly fishing fanatic I walked hundreds of miles of riverbanks and valleys, basins in mountain ranges. Found a lotta really cool rocks and artifacts..
Upper left a small fetish knapped of Chalcedony. The little pink one Knapped of Banded Pink Tourmaline. The Green shaped and polished from Green Serpentine and the little Blue shaped from I dunno what 😜 The big one was knapped, picked, and shaped from Ancient, hard Granite not local to this particular geographic area, but it's highly representative of the Humpback Chub, which is native to this Upper Colorado River drainage only.
Out hiking with Sonya Grrrl just a bit ago I found this very old hand shaped #Fish 🐠 #Fetish. Made by one of the #FirstPeople's who lived n' loved here where I walk now #Collapse #Aware #Autistic #Savant #Polymath into #History #Archaeology #Geology #Geophysics #Paleoclimatology #Rockhound #Science

Seismogram of the M6.0 earthquake in Fiji
Our @raspishake.bsky.social detected earlier today the M6.0 #earthquake that occurred in the Fiji (22/02/26 07:43:26 UTC)
Faacinated to receive it so clearly. Depth over 600 km, caused by subduction of Pacific plate under the Australian-Indian plate.

Color photograph of Dr. Marcia McNutt, prominent American geophysicist and president of the National Academy of Sciences. She is shown in a close-up head-and-shoulders portrait, resting her cheek on her right hand with elbow propped up, smiling warmly and directly at the camera with a bright, engaging expression. McNutt has shoulder-length light blonde hair styled in soft layers and wears subtle makeup. She is dressed in a dark blazer featuring a small circular lapel pin. Behind her, blurred bookshelves filled with volumes create a scholarly library or office setting, conveying approachability, leadership, and intellectual depth.
Geophysicist Marcia McNutt was elected the first female President of the National Academy of Sciences (NAS) #OTD in 2016. #WomenInSTEM #geophysics
