The race to map Africa's forgotten glaciers – in pictures
Project Pressure, a collaboration of photographers, scientists, web developers and cartographers, is working to document the terminal decline of many of the world's glaciers as they slowly melt away. Here they trek to the slopes of the Rwenzori mountains in Uganda and the Democratic Republic of the Congo

Project Pressure is a non-profit organisation which has set out to document the world’s vanishing glaciers. A recent expedition to Uganda and the Democratic Republic of the Congo started in burning sun trekking up through rainforestPhotograph: Klaus Thymann

There are still glaciers on each of the three mountains of the Rwenzori. Mount Speke is captured from Mount Stanley in this picture

Local porters were hired to help carry kit and provisions. Their experience on ice is limited

Vegetation creeps up the mountain as the temperature rises and the glaciers retreat. The Speke glacier used to reach where the lake now is

In order to get a view not seen for decades, and to establish if glaciers still exist on the western side of the Rwenzori, Project Pressure’s expedition went into the Democratic Republic of the Congo. Klaus Thymann, who heads Project Pressure, gives a briefing at the Elena hut

From the top of Mount Baker (4,844 metres), it is possible to get a clear view of all three peaks. Mount Stanley is to the right, Speke to the left

The expedition is taking a new route into the Congo, going down the West Stanley Glacier. The few people who come to the Rwenzori never go down on the west side

The glacier front is photographed and GPS co-ordinates are noted. Once published, Project Pressure’s material will be open source so it can be used for education and research

The black particles on the glacier absorb more heat, which then increases the melt rate. This form of glacial retreat is not unique to Africa. In Greenland the consequences are very noticeable

A unique view of the Rwenzori seen from the Congo side. A few days earlier the expedition roped down the West Stanley glacier (left). Project Pressure lead the expedition into Congo using an old disused route going through the burned-down war zone bordering Congo and Uganda

Some of the glaciers are almost gone. The Moebius on the west side will soon disappear completely

400 metres below the disappearing icefield, the communities of coffee farmers, who use the glacial water for irrigation of coffee and other crops, say climate change has disrupted rainfall patterns
