Greenpeace activists have sunk models of iconic structures from around the world into the Caribbean sea in Mexico to highlight the dangers of rising seas as a result of climate change.
Ministers are seeking a deal to set up a fund to oversee climate aid, ways to slow deforestation and a mechanism to share clean technologies such as wind and solar power.
Executive Director of Greenpeace International, Kumi Naidoo, said those suffering with climate change the most are those least responsible.
