Research Reveals Common Mechanism in Phonon Thermal Hall Effects Across Magnetic and Non-Magnetic Materials

A new study comparing magnetic and non-magnetic materials reveals that phonon thermal Hall effects share a common origin in extrinsic impurity scattering. The findings could help distinguish between competing mechanisms in thermal transport research.

Breakthrough in Understanding Phonon Thermal Hall Effects

Researchers have made significant progress in understanding the mysterious thermal Hall effects observed in insulating materials, according to a recent study published in Scientific Reports. The research team investigated the field-angle dependence of thermal Hall conductivity in both magnetic and non-magnetic compounds, revealing what analysts suggest is a common mechanism driven by extrinsic impurity-induced scatterings.

Southern Ocean Defies Climate Predictions, Maintaining Carbon Absorption Despite Global Warming

The Southern Ocean has maintained its crucial carbon absorption capacity despite climate models predicting a decline. Freshwater from melting ice has created a protective layer, but researchers warn this temporary solution could soon reverse, accelerating climate change.

Southern Ocean’s Surprising Carbon Absorption Defies Climate Models

According to a new study published in Nature Climate Change, the Southern Ocean surrounding Antarctica continues to absorb significant amounts of carbon dioxide despite climate models predicting this capacity would weaken due to global warming. Researchers from the Alfred Wegener Institute report that long-term measurements show the ocean’s carbon absorption has remained largely unchanged in recent decades, contrary to what climate projections had indicated.

Arctic Climate Shift Accelerates as Extreme Events Become Commonplace

A comprehensive review of Arctic climate data reveals that extreme weather events have shifted from rare occurrences to regular phenomena since 2000. Researchers describe a “pushing and triggering” mechanism where long-term warming destabilizes the climate system, making extremes more frequent and severe. Projections indicate these trends will accelerate throughout the century under current emission scenarios.

Arctic Climate Transformation Accelerates

Recent scientific analysis indicates that the Arctic is undergoing a fundamental climate transformation, with extreme weather and climate events increasingly becoming regular occurrences rather than rare anomalies. According to reports published in Nature Reviews Earth & Environment, the period since 2000 has marked a clear tipping point in Arctic climate patterns, with dramatic increases in the frequency and intensity of multiple types of extreme events across atmospheric, cryospheric, and oceanic systems.
