Impacts of Climate Change and Human Activities on Global Mountain Grasslands: Insights Into the Last Two Decades and Future Climate Scenarios

Earth's Future, Volume 14, Issue 2, February 2026.
Abstract Mountain grasslands are vital ecosystems providing critical services such as carbon sequestration, water regulation, and biodiversity conservation. However, these ecosystems are increasingly threatened by climate change and human activities. This study evaluates vegetation dynamics in global mountain grasslands (2000–2021) using remote sensing

Recent Tropical Cyclone Outer Size Increases in the Western North Atlantic

Earth's Future, Volume 14, Issue 2, February 2026.
Abstract The outer size of a tropical cyclone (TC) plays a pivotal role in its impact through a modulation of wind duration, rainfall extent and storm surge. While global and basin scale trends in TC size have been examined previously, whether there have been regional changes over time remains unclear. Here, using a suite of observations and reanalyses,

Impact of Wildfire Smoke on Respiratory Disease Associated Healthcare Utilization in Gang‐Won Province, South Korea, in 2017

GeoHealth, Volume 10, Issue 2, February 2026.
Abstract This study aimed to elucidate the association between wildfire smoke exposure and healthcare utilization for respiratory diseases in Samcheok (City), Gangwon Province, South Korea, focusing on a major wildfire that occurred on 6–9 May 2017. The relative risks (RRs) of healthcare utilization for respiratory diseases in a direct‐exposure area ...

Standing Meanders of the Antarctic Circumpolar Current: Evidence for Ridge‐Controlled Eddy Saturation

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The standing meanders of the Antarctic Circumpolar Current are key sites of mixing and meridional transport in the Southern Ocean, but their long‐term variability and trends remain poorly understood. Here, we investigate the Pacific‐Antarctic Ridge meander using satellite altimetry data from 1993 to 2023.

Carbon Cycle Succession Across a Permafrost Thaw Gradient in Northeastern Alberta as Revealed by δ13C in Dissolved Solids, Gases, and Particulates in Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract δ13C in particulate organic carbon (POC), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), carbon dioxide (CO2(g)) and methane (CH4(g)), together with geochemical modeling, were applied to describe carbon cycle evolution in 40 boreal lakes situated across a permafrost thaw gradient in northeastern Alberta, Canada, where ...

d‐Dimer With the Aortic Dissection Detection Risk Score May Improve Patient Selection for Acute Aortic Syndrome Diagnostic Imaging

Emergency Medicine Australasia, Volume 38, Issue 1, February 2026.
ABSTRACT Objective Acute aortic syndrome (AAS) refers to a group of life‐threatening cardiovascular emergencies that require computerised tomographic aortography (CTA) for definitive diagnosis. However, there is currently no validated risk‐stratification tool for AAS in low or intermediate risk patients using the aortic dissection detection risk score (

The Hydroclimate of the Ottawa River Basin Under Climate Change

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT The freshwater resource of the Ottawa River basin (ORB) is vital for ecological services and economic activities in the region. With climate change impacts becoming more evident, sustainable management is imperative. As a first step, it is important to assess impacts on hydro‐climatology.

Unravelling echinoid mass mortalities: a global overview of mechanisms, spatio‐temporal trends, and taxonomic insights

Biological Reviews, Volume 101, Issue 1, Page 221-236, February 2026.
ABSTRACT Mass mortality events (MMEs) have been occurring since the dawn of time. However, in contrast to terrestrial events, most marine MMEs remain undetected, largely due to the inaccessibility of many marine environments. One of the most notorious and best‐studied marine MMEs in modern times is that of the population collapse of the echinoid ...
