Differing Controls on the Cycling of Neodymium in the Atlantic and the Pacific

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Neodymium (Nd) isotopes ratios are regarded as a key proxy for past ocean circulation despite unsettled debate on marine Nd cycle controls, which opposes a “top‐down” hypothesis (surface sources dominate) and a “bottom‐up” hypothesis (sedimentary sources dominate), each with important implications for Nd isotope proxy interpretation.

Synchronized Heat Extremes in the Northern Hemisphere Based on a Complex Network

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Heat extremes occurring synchronously in multiple regions often result in more severe impacts than isolated heat events. Here we analyze observational and reanalysis data to objectively detect and examine the synchronization of heat extremes in the Northern Hemisphere and identify the regions that have remote linkages, particularly in western ...

A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...

Two‐Stage Dolomite Formation in Carbonate Platforms Revealed by Carbonate Clumped Isotope Thermometry

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The “dolomite problem” refers to the scarcity of dolomite in Cenozoic marine environments compared with its abundance in earlier strata. This discrepancy has been attributed to changes in marine environments or to insufficient thermal maturity required for dolomite formation.

Indo–Western Pacific Tropical Heating Anomalies Regulate the Cross‐Pacific Atmospheric River Highways During Boreal Summer

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Atmospheric rivers (ARs) constitute a global, interconnected highway network rather than isolated regional events. In boreal summer, cross‐Pacific ARs originate over Southeast Asia, are fueled by subtropical outflows from the Asian monsoon plume, transport warm, moist air across the North Pacific, and make landfall in North America (NA).
