Greenpeace activists project the future high water level at Hamburg's historic Speicherstadt (warehouse district). The new high water mark of almost eight metres above normal is to be expected as a consequence of climate change during storm tides.

Activists in inflatables display a banner which reads 'Climate Crisis - sea water levels rise'. The IPCC 'Special Report on the Ocean and Cryosphere in a Changing Climate', due to be published on 25th September, warns of an accelerated sea level rise by 2100.
