few days later Schellnhuber signed an agreement with the Qatar Foundation to jointly create a Climate change research institute in Qatar – a remarkable step as the country's wealth for decades had been based on exporting fossil fuels. In 2013, Schellnhuber was one of 18 prominent international scientists to launch the Earth League, a global interdisciplinary alliance of leading research institutes that focus on Earth system analysis and sustainability science, including economy. UN Security Council members Pakistan and UK asked him to speak at a meeting of the Council under the Arria Formula, the meeting at the UN headquarter in New York was attended by UN Secretary General Ban Ki Moon. In the runup of the world climate summit in Warsaw, Schellnhuber discussed possible ways forward with the president of Cop19, the Polish Minister of the Environment Marcin Korolec. To advance the state of science, Schellnhuber initiated the Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP) that involves more than 30 research teams from 12 countries. In 2013, the scientific journal Nature called it the "first comprehensive global-impact project" – it aims at identifying robust insights as well as research gaps, based on a yet unprecedentedly broad comparison of computer simulations of future climate change impacts such as water scarcity, floodings, or yield changes. In 2013, Schellnhuber's efforts resulted in the Impacts World Conference in Potsdam followed by a special feature on first ISI-MIP results in the Proceedings of the National Academy of Sciences (PNAS). Schellnhuber has been serving as chair of the Climate-KIC (Knowledge and Innovation Community) governing board, which is affiliated to the European Institute of Innovation and Technology (EIT). This institution aims at fostering low-carbon entrepreneurship and innovation. Schellnhuber signed the 2005 Potsdam Denkschrift calling for a change in thinking to enable sustainable development. Personal life He is married to Margret Boysen. Publications Schellnhuber has published more than 250 scientific papers and has authored, co-authored, or edited 50 books or book chapters.
