New research from Rutgers University reveals that meltwater from Antarctic ice shelves contributes far less iron to surrounding ocean waters than scientists had assumed. Instead, most iron originates from deep ocean water and continental sediments. The findings challenge expectations about iron fertilization and its role in carbon absorption.

Researchers have achieved a breakthrough by recreating wildfire-induced thunderstorms, known as pyrocumulonimbus clouds, in Earth system models for the first time. This simulation captures how intense bushfires generate severe weather that can spread fires further. The work enhances understanding of fire-atmosphere interactions amid worsening climate conditions.
