Brazilian artist Nele Azevedo carved the figures out of ice and placed them on steps in the central Gendarmenmarkt square where they began to melt within about half an hour.
Temperatures in Berlin were about 73 degrees Fahrenheit (23 Celsius) Wednesday.

The installation, Melting Men, was meant to spotlight the World Wildlife Fund's warning that melting ice could possibly cause levels to rise more than 3.3 ft by 2100.
The group warns that the warming of the Arctic will change weather in different parts of the world and increase the release of greenhouse gases into the atmosphere.
Since 2005, Azevedo has been setting up her Melting Men in various countries around the world. Although originally intended as a critic of the role of monuments in cities, environmentalists around the world are adopting her work as climate change art.

When asked if she was a climate activist, Azevedo told greenmuze.com: 'No. I'm an artist, master of visual arts from the University of Sao Paolo.
'This work was conceived as a critical view of the official historical monuments. As the reading and interpretation of an art piece is open, I'm glad it can also speak of urgent matters that threaten our existence on this planet.'
'The project started with solitary figures, later a multitude of small sculptures of ice were placed in public spaces of several cities. The memory is inscribed in the photographic image and shared by everyone. It is not reserved to great heroes nor to great monuments.'
