Each Glacier Has a Unique Organic Matter Composition

by Saima May Sidik 15 October 202415 October 2024

Like snowflakes, no two glaciers are alike: Carbon-containing compounds released from glaciers vary from place to place, meaning climate and ecosystem effects of melting could vary as well.

Clays May Have Slowed Earth’s Recovery After the Great Dying

by Kate Evans 19 August 202419 August 2024

Without tiny marine organisms using silica for shells, Earth’s oceans generated more clay, released more carbon dioxide, and kept Earth warmer for longer.
