Alun Hubbard, Professor of Glaciology from Aberystwyth University, has recorded an audio diary for us of his annual trip to Greenland's ice sheet. It's melting faster than ever before - something he's been monitoring on his summer expedition there.

In part three of his reports, he's moving round the island to look at one specific glacier, Store Gletscher, to see why it's producing more icebergs than before.
