How the Rise of a Salty Blob Led to the Fall of the Last Ice Age

by Emily Gardner 2 February 20262 February 2026

Scientists have long suspected that high salinity levels in the deep ocean were responsible for keeping carbon dioxide locked away during the last ice age. New research finds the strongest evidence yet.

Three people in bright yellow and orange jackets appear to be on a boat. They are reaching for a collection of tanks that will be lowered into the water. Two other ships are visible in the distance.

Las olas de calor marinas lentifican el flujo de carbono de los océanos

by Mack Baysinger 5 January 20265 January 2026

Cuando el plancton se encuentra en agua caliente, la materia orgánica se estanca en la superficie e interrumpe el transporte de carbono hacia el fondo océanico.

Glacier Runoff Becomes Less Nutritious as Glaciers Retreat

Javier Barbuzano, Science Writer by Javier Barbuzano 25 November 202525 November 2025

Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.
