Over 47 years, the slow arithmetic of a warming planet has been written in ice: more than 12 trillion tons lost from Greenland and Antarctica, measured not by human hands but by instruments orbiting silently overhead. What the satellite record reveals is not merely a quantity but a rhythm — one that is quickening, as glaciers accelerate their march toward the sea. The consequences are already in motion, reshaping coastlines and climate patterns in ways that will outlast the decisions that set them in course.

Accelerating ice loss threatens coastal communities and ecosystems through sea level rise and climate disruption.
