Climate Science
Researchers have discovered the oldest directly dated ice and air samples on Earth, dating back 6 million years, in the Allan Hills region of East Antarctica. This breakthrough provides unprecedented insights into the planet's ancient climate and atmosphere. The finding, detailed in a recent study, reveals a significant cooling trend over millions of years.

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.
