Climate pilgrims and environmental activists are sending a strong message for more climate justice and are jointly calling for a fair and internationally binding agreement at the upcoming World Climate Conference in Paris. Colourful sailing boats and canoes accompany the pilgrims on their way to cross the river Elbe in Hamburg. The banner on the sailing boat says: "Climate Protection needs tailwind". The three-month pilgrimage in which most of the activists in Hamburg are participating, leads from Flensburg to Trier to the 21st UN Climate Change Conference in Paris.
