The shallow crust has recovered since California’s 2019 quake, but damage persists at depths greater than 10 kilometers.The 11 November 2025 landslide at Hongqi Bridge in China
14 November 2025 @ 8:27 am
A large landslide has destroyed a 662 m long highway viaduct in China. Over the last two days there has been considerable media coverage of a large, highly destructive rockslide that occurred at Hongqi Bridge in Sichuan Province, China. There is a very interesting set of images of the bridge during construction on the Highest […]How Algae Helped Some Life Outlast Extinction

12 November 2025 @ 1:59 pm
NASA's Orbiting Carbon Observatory-2 satellite reveals an impressively dynamic picture of the Earth's carbon cycle, yet it may be prematurely decommissioned and destroyed due to budget cuts.When Cascadia Gives Way, the San Andreas Sometimes Follows
12 November 2025 @ 1:56 pm
Roughly half of the earthquakes that occurred along the southern Cascadia subduction zone over the past 3,000 years were temporally associated with earthquakes along the northern San Andreas fault.Speedy Flyby Adds New Organics to Enceladus’s “Primordial Soup”
12 November 2025 @ 1:54 pm
A new analysis of old Cassini data has also verified past detections of complex organics in Saturn’s E ring, strengthening the chemical ties between the ring and its progenitor.
Robust increase in observed heat storage by the global subsurface, Cuesta-Valero et al., Science Advances
Changes in heat storage within the different components of the climate system alter physical and biogeochemical phenomena relevant for human societies and ecosystems. Among such processes, permafrost thawing, soil carbon storage, and surface energy exchanges depend on the persistent heat gain by the continental subsurface. Nevertheless, there are not enough data to estimate ground heat storage at the global scale after the year 2000. We solve this problem by expanding the database of geothermal data with remote sensing observations
The planet continues to warm due to human activity; bouts of cold weather don’t change this.
Satellites around the world measure temperatures at different places throughout the year. These are averaged to calculate annual global temperatures.
The past ten years (2015-2024) have been
