Secretary of State John Kerry has said that terrorism is a more dangerous global threat than climate change,"Let me just say that one of the greatest challenges of our times besides the fight against extremism is to deal with the enormous battle of climate change," Kerry said in Denmark, perhaps indicating that he is changing course from earlier pronouncements that climate change is the greater threat."The threat of climate change is, without question, one of the defining if not the defining challenge — I'd probably give violent extremism — the defining threat of a generation, and it is a challenge that everybody has to approach with urgency," Kerry said while in Norway.Kerry is working with other nations on fighting terrorism, as part of his role as U.S. secretary of state. He gave credit to Denmark for its help on counter-terrorism."I am convinced by what we are achieving with the help of Denmark and others in Iraq and Syria that we are going to be successful over time," Kerry said,Kerry is working with Russian diplomat Sergey Lavrov on an approach to the fight in Syria,In 2014, Kerry said climate change was as great a threat as terrorism and poverty, according to CNN. He still maintains the importance of the dangers of climate change."If we were to lose the ice sheet of Greenland, we would see a sea level rise of some 22 feet over the course of this century," he said in the Examiner report.In Norway, Kerry warned of a possible climate change "catastrophe.""Climate change is looming out there, a decidedly different challenge, but, let me tell you, one that is existential and already impacting our lives, giving us a preview of the planet-wide catastrophe that we would face if we don't change course," the Examiner reported.
