Plutonium isotope anomaly discovered in Southern Hemisphere glaciers
Diagram showing the deposition of plutonium isotopes on the surface of a glacier. Credit: IFJ PAN The latest findings carried out by scientists at the PAN Institute for Nuclear Physics shed new light on the process by which plutonium isotopes accumulate in glaciers in the Southern Hemisphere. Analyzing samples of cryoconite, a sediment deposited in glaciers, not only reveals differences…

Modeling study reveals that ‘greening’ of Africa’s Sahara Desert could change the climate of the Northern Hemisphere
Winter temperature (a, b), summer temperature (c, d), and annual precipitation (e, f) between preindustrial values, paleoclimate model (MH-PMIP), and Sahara Greening Model (MH). Comparison of the reconstructed model and environmental surrogate-GS). Credit: Past Climate (2024). DOI: 10.5194/cp-20-1735-2024 Africa’s Sahara Desert may be considered an extreme environment for flora and fauna to thrive, with vast expanses of barren sand and…
