Ice Planet Update: Antarctica Retreat Study Signals Future Ice Loss
The ice along Antarctica’s ‘grounding lines’ has been largely stable over the past 30 years – but ice has retreated by more than 40 km in some areas, a new […]

Ice World Orbital Recon: Increased Plant Cover On Earth’s Antarctic Peninsula
The white, monochromatic vistas of Antarctica, a continent practically synonymous with ice, are becoming more verdant—at least around some of its edges. According to an analysis of 35 years of […]
