This section of the website highlights how glaciers interact with climate, and how changing climate is changing glaciers around the world today. Globally, glaciers are receding and shrinking in response to atmospheric warming. The signal is remarkably consistent across different continents and mountain ranges. Glaciers are a critical water resource in many mountain regions of […]

Sea ice and ice shelves What is sea ice? Sea ice is frozen sea water; it perennially expands and contracts during each year’s winter and summer. Amongst the sea ice are icebergs calved from tidewater glaciers and ice shelves. Melting sea ice does not contribute directly to sea level rise (ice floats and displaces the

A paper in this weeks’ Nature by Mulvaney et al. 2012 suggested that the climate around the Antarctic Peninsula has varied extensively over the Holocene. This data is derived from a 363.9 m ice core from the Mount Haddington Ice Cap on James Ross Island.

Ice shelves are floating tongues of ice that extend from grounded glaciers on land. Snow falls on glaciers, which flow downstream under gravity. Ice shelves are common
