Ban Ki-moon is the eighth and current Secretary-General of the United Nations. Elected to the position in 2007, Ki-moon was unanimously re-elected in 2011.

He will serve until 2016. Prior to becoming Secretary-General of the UN, Ki-moon was a career diplomat in South Korea's Ministry of Foreign Affairs.

Upon assuming his role as the head of the UN, Ban Ki-moon immediately made climate change an area of focus for the organization. Starting with the 2007 Climate Change Summit, Ki-moon has led an extensive effort to generate a global agreement to curb greenhouse gas emissions and tackle climate change.

During an interview earlier this year, Ban Ki-moon said reaching a new international agreement on climate change is his top hope and biggest goal for the year.
