U.N. Secretary General Ban Ki-moon discusses with Holocaust survivor Marian Turski, chairman of the Council for the Museum of the History of Polish Jews (R) during his visit at the Auschwitz-Birkenau memorial and former concentration camp November 18, 2013. Ban urged the European Union on Monday to stay at the vanguard of efforts to combat climate change, sweeping aside arguments led by Poland and business leaders that the bloc has to prioritise economic growth. Talks in Warsaw due to end on Friday are meant to be a step on the way to a new global deal in 2015 on how to limit global warming to the 2 degrees Celsius (3.6 Fahrenheit) that scientists say would prevent the most devastating effects of climate change.
