Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Water Vapor Spectroscopy and Thermodynamics Constrain Earth's Tropopause Temperature

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract As Earth warms, the tropopause is expected to rise, but predictions of its temperature change are less certain. Longstanding theories employing “gray” radiation tie the tropopause temperature to outgoing longwave radiation (OLR), but this is in contrast to recent work in which simulations exhibit a Fixed Tropopause Temperature (FiTT) even as ...

Disentangling the Effects of Global and Regional Drivers on Diverse Long‐Term pH Trends in Coastal Waters

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Unlike declines of pH in the open ocean on the total scale (pHT), coastal systems have shown complex long‐term trends in pHT due to a multitude of global and regional drivers. These drivers include changes in nutrient loading, human‐accelerated chemical weathering of watersheds, acid‐rain and land‐use changes, and ocean acidification due to ...

Recent Increases in Missouri River Streamflow Driven by Combined Effects of Climate Variability, Land‐Use Change, and Elevated CO2

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Missouri River streamflow increased substantially during the 20th century, with multiple large floods occurring since 1990. Using land surface models and water budget simulations, we examined the extent to which increased flow was driven by natural climate variability, anthropogenic climate trends, land‐use and land‐cover change (LULCC), and ...

Sources, Pathways, and Drivers of Sub‐Antarctic Mode Water Formation

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Sub‐Antarctic Mode Waters (SAMWs) form to the north of the Antarctic Circumpolar Current in the Indo‐Pacific Ocean, whence they ventilate the ocean's lower pycnocline and play an important role in the climate system. With a backward Lagrangian particle‐tracking experiment in a data‐assimilative model of the Southern Ocean (B‐SOSE), we address ...
