The Double Dip: How Tropospheric Expansion Counteracts Increases in Extratropical Stratospheric Ozone Under Global Warming

Geophysical Research Letters
In response to rising CO2, chemistry‐climate models (CCMs) project that extratropical stratospheric ozone will increase, except around 10 and 17 km. We call the muted increases or reductions at these altitudes the “double dip.” The double dip results ...

Biases and Uncertainties in Radiosonde‐Based Precipitable Water Vapor

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Precipitable water vapor (PWV) plays an important role in weather and climate phenomena. Accurate PWV measurements based on radiosonde observations are essential for assessing remote‐sensing measurements and long‐term trends. This study examines the performance of PWV algorithms, including their intrinsic biases and their sensitivity to ...

Misrepresentation of Human Climate Fingerprint in DOE Report

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract A July 2025 report from the U.S. Department of Energy (DOE) made the key claim that the stratosphere has warmed since 2000, contrary to model projections and inconsistent with the expected anthropogenic fingerprint. The DOE report provided no references or data to support this claim.

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...

Elevated UV‐B alters anti‐herbivore plant defence allocation, while silicon supplementation maintains resistance

Functional Ecology, Volume 40, Issue 9, Page 2982-3000, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The impacts of elevated surface ultraviolet‐B (UV‐B) on ecological processes, such as anti‐herbivore defence in plants, remain poorly understood. Many cereal crops depend on accumulating silicon (Si) in their tissues to resist insect herbivory.

The Secretome Derived From Human Umbilical Cord Mesenchymal Stem Cells Improves Skin Photoaging by Enhancing Mitophagy to Inhibit the cGAS‐STING Pathway

Aging Cell, Volume 25, Issue 9, September 2026.
HUC‐MSC‐derived SCT alleviates UV‐induced skin photoaging. It acts by enhancing mitophagy to clear damaged mitochondria, thereby suppressing the pro‐inflammatory cGAS‐STING pathway. This work identifies SCT as a novel cell‐free therapy targeting mitochondrial quality control to counteract sterile inflammation in aging. ABSTRACT Ultraviolet (UV)‐induced

From fossil to bio‐circular plastics: the environmental benefits of bio‐attributed acrylonitrile butadiene styrene in single‐use cystoscopes

BJU International, Volume 138, Issue 3, Page 480-490, September 2026.
Background Single‐use cystoscopes are increasingly adopted in urology, but concerns regarding their environmental footprint persist. Substituting conventional fossil‐based plastics with bio‐attributed materials may reduce life cycle impacts, yet the magnitude and robustness of this benefit remain uncertain.

Disentangling Anthropogenic Effects on Southern Hemisphere Circulation and Surface Climate: A Multi‐Model Large Ensemble Approach

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Southern Hemisphere (SH) circulation and surface climate changes are emerging in recent decades. For example, in most seasons, the SH Hadley cell edge and the eddy‐driven jet stream have shifted polewards, and the Southern Annular Mode (SAM) has trended towards its positive phase.
