Worldwide, glaciers are shrinking and receding. In fact, glacier recession and thermal expansion of the ocean together account for 75% of today’s observed sea level rise. Glaciers are small and have short response times, so they react quickly to changes in air temperature and precipitation. Glaciers around the Antarctic Peninsula are shrinking particularly rapidly, and this is exacerbated by ice shelf collapse.
This section summarises how glaciers are behaving and shrinking around the Antarctic Peninsula, in nearby Patagonia in South America, and more broadly around Antarctica.
