Editor’s summaryFuture rises in sea level will depend primarily on the rate at which the Antarctic and Greenland ice sheets discharge their ice into the sea, and that rate depends critically on the flow properties of the temperate ice that exists near the beds and within the margins of the fastest-flowing ice streams. Schohn et al. present results from the world’s largest ice-deformation apparatus revealing how shear deformation in temperate ice occurs.
