The snow-capped summit of Mount Kilimanjaro has melted away to reveal the tip of the African peak for the first time in 11,000 years.
The glaciers and snow which kept the summit white have almost completely disappeared.
Although scientists had predicted the melt would happen, it is 15 years sooner than they had predicted.
The white peak of the 19,340ft mountain has long formed a stunning part of Tanzanian landscape, not least because it is only 200 miles south of the equator.
The photograph is part of the NorthSouthEastWest exhibition by The Climate Group, a book of which will be presented to ministers at the G8 energy and environment summit in London.
Steve Howard of The Climate Group said: “Climate change is real. So are the solutions, which are practical, affordable and in many cases, profitable.
“This exhibition shows us that a low-carbon economy is the only sustainable future for our planet.”
The G8 meeting comes a day after the WWF warned Himalayan glaciers are receding at among the fastest rates in the world because of global warming.
The environmental group warned that the melting could result in water shortages for millions of people who rely on rivers supplied by the glaciers in China, India and Nepal.
