Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, Volume 38, Issue 4, Page 259-265, August 2026.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.

Observations of Offshore Low‐Level Jets Off the U.S. East Coast Reveal Systematic Biases in ERA5 and HRRR

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Low‐level jets (LLJs)—wind speed maxima typically occurring a few hundred meters above the surface—are common off the U.S. East Coast and influence many atmospheric processes with societal importance, including cloud formation, aviation safety, and search‐and‐rescue.

Marine Aerosol to Refinery Emissions: Transport and Evolution of CCN in the Houston Metropolitan Area and Their Impact on Cloud Formation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Experiment of Sea Breeze Convection, Aerosols, Precipitation and Environment (ESCAPE) campaign aimed to untangle the impacts of contrasting aerosol sources on cloud microphysical properties within deep convective cells using airborne observations with the National Research Council Canada (NRC) Convair CV‐580 research aircraft.

A Vast Valley Network Beneath the Greenland Ice Sheet

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

Opposite Trends of Eddy Kinetic Energy in the Tropical Indo‐Pacific Ocean Since the 1990s

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Oceanic mesoscale eddies are pivotal in redistributing mass and heat. Despite a warming‐induced increase in global oceanic stratification, previous studies have reported a global increase in mesoscale eddy activity, particularly in eddy‐rich regions, pointing to a complex and regionally contingent response to climate change.

Sea Ice Latent Heat Becomes More Active in the Arctic Sea Ice Energy Budget

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Arctic sea ice has experienced rapid decrease in recent decades. The sea ice property changes have altered its thermodynamic processes, enhancing the heat exchange among atmosphere‐ocean‐ice surface. However, heat exchange associated with sea ice phase‐change process, which is defined as sea ice latent heat, have received relatively little ...
