Changes in Sea Ice Microstructure Could Affect Climate Models

by Skyler Ware 20 May 202620 May 2026

Granular sea ice needs to be twice as porous as columnar ice to allow water to flow through it—up to 10% brine by volume.

The Global Impact of Losing U.S. Sea Level Science

by Andra J. Garner, Robert E. Kopp, Gregory G. Garner, Aimée B. A. Slangen and Benjamin P. Horton 15 May 202615 May 2026

Cuts to climate science risk halting or even erasing decades of progress in global change research—just as risks from rising seas demand better data, informed decisionmaking, and faster action.
