Geopolitical Energy Shock Triggers Rural Aerosol Resurgence — Evidence from India’s 2026 LPG Crisis

India's 2026 LPG crisis, triggered by geopolitical energy shocks, forced reverse migration to rural Bihar and eastern Uttar Pradesh, where unaffordable fuel costs drove households back to solid-fuel combustion, significantly increasing local aerosol pollution and exposing a critical structural vulnerability in the nation's clean-cooking transition that prioritizes access over supply security.

Millennial-scale ice retreat after the first Phanerozoic glaciation

This study reveals that the post-glacial recovery following the Late Ordovician Hirnantian glaciation was marked by seven millennial-scale cold–warm cycles driven by episodic ice-sheet discharge, demonstrating that such climate instability is a fundamental feature of Earth's history that significantly influenced early biotic recovery patterns.

A Relationship Between Baroclinic Tidal and Wave Horizontal Spectral Energy and Stratification on the Australian Continental Shelf

This study analyzes temperature and velocity data from Australian moorings to establish a power-law relationship between upper-ocean stratification and baroclinic wave energy that holds for specific depth and temperature difference thresholds, offering a cost-effective method to predict internal wave energy fields and mixing potential.
