Representatives from about 180 countries have met to discuss the global fight against climate change in Paris and tried to find a common solution to climate issues such as the earth's rising temperature and the use of fossil fuels.
The French government will officially take over directing the road map of the climate talks in Monday's opening ceremony.
Police have taken tighter security measures around the conference center in Le Bourget and closed roads to the meeting center.
French Foreign Minister Laurent Fabius indicated on the weekend, "It will be the turning point, which is what the world requires."
US President Barack Obama attended the summit and said, "As the leader of the world's largest economy and the second-largest [greenhouse gas] emitter ... the United States of America not only recognises our role in creating this problem, we embrace our responsibility to do something about it."
Chinese President Xi Jinping indicated it is quite significant to talk about climate issues and address the economic differences between nations. He said the organisation would allow different countries to improve their solutions to the problem of global warming.
The UN General Secretary Ban Ki-Moon said "I urge you to instruct your negotiators to choose the path of compromise and consensus,” and underlined, “Bold climate action is in the national interest of every single country represented at this conference. The time for brinksmanship is over."
Russian President Vladimir Putin was also among the attendees, however he was missing on the stage when the leaders were posing for a family photo.
Gokhan Yucel, COP21live.com director, spoke to TRT World and said that at the end of the summit it could be possible for the leaders to determine the terms in regards to keeping global warming under the degree of two.
He also stated there would not be a well-rounded agreement on solving all key issues such as reducing fossil fuel energy and carbon emissions at the climate summit.
“Nearly 190 world leaders who are the high level of participations will try to find solution but they will not agree on any result that threat their national interests,” he said.
