No Evidence for Strongly Enhanced Northern Hemisphere Cooling From Extratropical Versus Tropical Eruptions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Volcanic eruptions in the Northern Hemisphere extratropics have been reported to produce several times greater cooling in that region than tropical eruptions of similar magnitude. Using a large ensemble of simulations spanning the eruption size range from 5 to 40 Tg of stratospheric sulfur, we find that the extratropical‐to‐tropical cooling ...

A review of paleoclimate reconstruction based on soil physical and chemical properties

Guan'gai paishui xuebao
Soils preserve critical geochemical and mineralogical information that records past climatic conditions. Consequently, soil physical, chemical, and biological properties have become important proxies for paleoclimate reconstruction.

Symbiont‐Mediated Molybdenum Cycling Shapes Coral Skeletal Mo Isotopes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Coral skeletal trace‐metal compositions are commonly assumed to derive from seawater, yet the extent to which biological processes contribute remains poorly constrained. Here we present the first paired Mo isotope measurements of coral tissue, symbiotic zooxanthellae, and skeleton.

Melt Production and Volatile Release From Thermochemical Mantle Plumes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain poorly constrained.

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poorly constrained.

Differential Impacts of Proxy Archives on Paleoclimate Reconstruction Performance

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Reconstructing past climates is challenging because pre‐instrumental observations are geographically sparse and proxy records are noisy; data assimilation offers one approach to address these limitations. Although such reconstructions are now widespread, the extent to which different proxy archives determine their accuracy remains unclear.

Super Warm Early Eocene Simulations With HadGEM3‐GC31‐LL

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract The early Eocene Climatic Optimum (EECO; 53.3–49.1 million years ago) represents the period of greatest sustained warmth in the Cenozoic (last 66 million years), with proxy‐data indicating global‐mean temperatures 10–16°C above preindustrial and atmospheric CO2 ${\text{CO}}_{2}$ concentrations of 1,200–2,500 ppmv.

Different Orbital Controls on Detrital Magnetic Components in the Ninety‐East Ridge Since the Late Pleistocene

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Magnetic minerals preserved in marginal‐sea sediments can serve as distinct fingerprints for unraveling paleoenvironmental evolution. However, the forcing mechanisms that govern the transport and accumulation of individual magnetic minerals at orbital timescales remain poorly constrained.
