Scientists revisit the question of global temperatures during the last ice age. They tackle this with state of the art climate models and geochemistry to give a picture that’s more accurate than ever before.

North Atlantic deep water forms primarily in more extreme northern latitudes due to the colder, saltier water with a higher density. When this flow of water goes south it mixes with the cold Antarctic water and then redistributes into other parts of the world. As high latitude warming and ocean refreshing reduce water density, North […]
