Two Greenpeace activists hold a banner reading "Hot Water = Climate Crisis" at 40 m depth near soft coral Paramuricea clavata, at Formiche della Zanca, Elba, Italy.
This species has been affected by several mass mortality events in the Mediterranean sea due to high temperature water.
Greenpeace Italy has set up an underwater station to monitor the effects of climate change. 8 thermometer dataloggers have been placed underwater between 5 and 40m depth to measure sea temperatures.
