Centennial-Scale Jumps in CO2 Driven by Earth’s Tilt

Katherine Kornei, Science Writer by Katherine Kornei 8 November 20248 November 2024

Antarctic ice records uncovered seven previously unknown jumps in atmospheric carbon dioxide. These events may have been driven by changes in Earth’s tilt.

Phytoplankton Shield Ice Shelves from Summer Heat

by Saima May Sidik 20 September 202420 September 2024

Spring blooms shade Antarctic ice shelves, causing them to melt 7% more slowly than they would if they were surrounded by clear, bloomless waters.
