THAW showcases the rapidly growing number of blue lakes and rivers that form on the Greenland ice cap – one of the most inaccessible areas on earth. Here, in the pristine landscape, stripped to the bare minimum of colours and shapes, the dramatic impact of climate change is more obvious than anywhere else in the world. THAW is more than just a photography project – it is a collaboration between science, nature and our ability to discuss it through photographs. I visited the Arctic polar ice cap, working alongside several leading scientists that study it, and was overwhelmed by the scale of the landscape and the enormity of associated problems. All of that I brought together in THAW. Overall, the project was two years in the planning, with the assistance of Prof Alun Hubbard, Prof Julian Dowdeswell and Dr Poul Christoffersen.
