Earth Day: Leading climate scientists publish essential elements for a global climate agreement

04/22/2015 - The Earth League, an international alliance of prominent climate scientists, outlined the elements of a global climate agreement in a stark statement published today, coinciding with Earth Day. Written by 17 world-leading scientists, among them PIK director Hans Joachim Schellnhuber, their statement clarifies in eight essential elements, what an international climate agreement in line with the 2 degree target should achieve in Paris in December. Bold action by decision-makers is required now to pave the way for a successful international agreement to reduce the risk of dangerous climate change, the Earth League members say.

2015 is a critical year for humanity: "It is a moral obligation, and in our self-interest, to achieve deep decarbonization of the global economy via equitable effort sharing. This requires reaching a zero-carbon society by mid-century or shortly thereafter, thereby limiting global warming to below 2°C as agreed by all nations in 2010. This trajectory is not one of economic pain, but of economic opportunity, progress and inclusiveness. It I a chance too good to be missed”, prominent scientists like Mario Molina of Centro Mario Molina, Jennifer Morgan of the World Resources Institute, Ottmar Edenhofer of Mercator Research Institute on Global Commons and Climate Change, Carlos Nobre of National Institute for Space Research (INPE), Lord Nicholas Stern of London School of Economics and Political Science, Johan Rockström of Stockholm Resilience Center and other eminent authors say in the Earth Statement.

They outline eight essential elements of climate action in Paris, ranging from the implementation of commitments to limit global warming to below 2 degrees, to the remaining global carbon budget, a transformation of the economy, fair decarbonization pathways, climate innovations, building resilience, the safeguarding of carbon sinks and vital ecosystems and the realization of new scales and sources of climate finance for developing countries.

The Earth Statement will be presented by Rockström and Schellnhuber at the 4th Nobel Laureates Symposium on Global Sustainability in Hong Kong “4C: Changing Climate, Changing Cities” hosted by the Potsdam Institute for Climate Impact Research and Asia Society Hong Kong (22-25 April) on Thursday – this will mark the beginning of outreach to leading decision-makers and thinkers.
