The science is clear

We are facing an unprecedented global emergency

We must act now.

“There is sufficient evidence to draw the most fundamental of conclusions: now is the time to declare a state of planetary emergency. The point is not to admit defeat, but to match the risk with the necessary action to protect the global commons for our own future.” Professor Johan Rockstrom, Director of the Potsdam Institute for Climate Impact Research

“This is an emergency and for emergency situations we need emergency action.” Ban Ki-Moon, Former UN Secretary-General

"The climate emergency is our third world war. Our lives and civilization as we know it are at stake, just as they were in the Second World War." Professor Joseph Stiglitz, Economist, recipient of the Nobel Memorial Prize in Economic Sciences

“Climate change is the greatest security threat of the 21st century,” Maj Gen Munir Muniruzzaman (Retd.), chairman of the Global Military Advisory Council on Climate Change

“Climate change is moving faster than we are - and its speed has provoked a sonic boom SOS across our world. We face a direct existential threat.” António Guterres, United Nations Secretary-General

"We have all the resources we need to deal with this. There is nothing magical about reducing carbon dioxide in the atmosphere. We just don’t have the political or economic will to do this.” Professor Stephan Harrison, Professor of Climate and Environmental Change, University of Exeter

“Listen to the cry of the earth and the cry of the poor, who suffer the most. The urgent need for interventions can no longer be postponed.” Pope Francis

“The future of the human race is now at stake.” Rowan Williams, Former Archbishop of Canterbury
