These pictures, by photographer Timo Lieber, document the phenomenon.

Ive always had a passion for the ice, Leiber toldThe Guardian.

Id been to Iceland seven or eight times, to Arctic Norway and to Greenland.

Greenlands contribution to global sea-level rise is about three times that of Antarctica.

I saw how fast the landscape was changing and wanted to put it into a body of work.

Timo Lieber flew over Greenlands vast icescape in a twin-engine plane.

The pilot would bank the plane sharply allowing Lieber to shoot through a tiny hole in the window.

The images are deliberately abstract, Lieber said.

I didnt want them to be documentary photographs.

Theyre beautiful, but what youre looking at is climate change at its worst.

My favourite is the one that looks like an eye.

The melt ponds play an important role in iceberg calving.
