"I am not choosing between the fight against terrorism and the fight against global warming. These are two major challenges that we must overcome," Hollande said during the opening ceremony of the UN climate summit in Paris.
He said efforts were needed to rid the planet of both terrorism and natural disasters for the benefit of future generations.
Paris is currently hosting the 21st UN Climate Change Conference, due to run until December 11. More than 130 leaders and top diplomats from dozens of countries are attending the summit, at which they are expected to reach a legally binding agreement on climate change.
On November 13, Daesh, also known as ISIL/The Islamic State, carried out a series of coordinated attacks at various locations in the French capital, killing 130 people and injuring over 350 others. Following the attacks, Hollande announced plans to create a broad anti-terror coalition with the participation of Russia and the United States.
