Greenpeace Poland director Maciej Muskat and Solar Generation Student Delegates mark the opening of the UN climate talks in Poznan by unveiling a 3 meter high sculpture depicting the earth on the brink of destruction from a ‘tidal wave’ of CO2. The sculpture, ‘Planet Earth: Tipping Point’, by Dutch artist Ruut Evers, shows the fragile planet cowering beneath a giant ‘wave’ made of wood and coal. It remains on display for the duration of the climate talks, serving as a daily reminder to government negotiators that the stakes couldn’t be higher.
