The Greenpeace ship, Rainbow Warrior, sails past the Piazza San Marco in Venice, Italy, bearing the message "Save the Climate, There is no Planet B". Venice is one of the low-lying cities in the planet identified by scientists to be under severe threat from sea level rise due to climate change. The Rainbow Warrior is currently on a 'Mediterranean Energy Tour', to campaign for a shift in energy investments away from fossil fuels towards renewable energy to help avert the worst impacts of climate change.
