Gondola trips are a traditional part of visiting Venice for those who can afford the steep tourist prices, but I went a little off-script on a recent visit and chose a different, but equally iconic, vessel. We Are Here Venice, an NGO that promotes the safeguarding of a city deeply affected by climate breakdown and countless human-made activities, invited me on board the Greenpeace ship the Rainbow Warrior, the purpose of whose visit was anything but touristic.

I have taken part in two Arctic tours with Greenpeace: one on the Esperanza (now defunct, not my fault!) and another on the Arctic Sunrise. I had previously sailed with two of the crew who are now on the Rainbow Warrior, and there they still were, fighting for climate justice around the world.
