Increasing heat is super-charging Arctic climate and weather extremes

Phys.org: Earth science - Tue, 10/21/2025 - 18:16

By evaluating historical climate records, observational and projection data, an international team of researchers found a "pushing and triggering" mechanism that has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across all system components—the atmosphere, ocean and cryosphere—this century.

Seismic anisotropy offers insight into viscous BLOBs at base of Earth's mantle

Phys.org: Earth science - Tue, 10/21/2025 - 16:57

In some parts of Earth's interior, seismic waves travel at different speeds depending on the direction in which they are moving through the layers of rock in Earth's interior. This property is known as seismic anisotropy, and it can offer important information about how the silicate rock of the mantle—particularly at the mantle's lowermost depths—deforms. In contrast, areas through which seismic waves travel at the same speed regardless of direction are considered isotropic.
