United Nations, October 6, 2016: The landmark Paris agreement on climate change will enter into force on November 4, after a coalition of the worldâ€™s largest polluters and small island nations threatened by rising seas pushed it past a key threshold on Wednesday.
President Barack Obama hailed the news as â€œa turning point for our planet,â€ and UN Secretary-General Ban Ki-moon called the agreementâ€™s strong international support a â€œtestament for the urgency of action.â€ Katharine Hayhoe, a climate scientist at Texas Tech, called it: â€œA moment of bright hope in the increasingly discouraging landscape of climate science.â€
UN deputy spokesman Farhan Haq said late Wednesday that the European Union and 10 countries deposited their instruments of ratification on Wednesday. The percentage of emissions they account for topped the 55 percent threshold needed for the treaty to take effect, he said.
Haq said the 10 countries were Austria, Bolivia, Canada, France, Germany, Hungary, Malta, Nepal, Portugal and Slovakia.
â€œI am delighted to announce that today the Paris Agreement will cross the second and final threshold needed for entry into force, and will enter into force on 4 November 2016,â€ Ban said in a statement issued from Europe. â€œGlobal momentum for the Paris Agreement to enter into force in 2016 has been remarkable. What once seemed unthinkable is now unstoppable. â€
The deal takes effect 30 days after 55 countries, accounting for at least 55 percent of global emissions, have adopted it. Sixty-two countries had done so as of Tuesday but they accounted only for about 52 percent of emissions.
A UN website said that as of Wednesday afternoon 73 of the 197 parties to the treaty, accounting for 56.87 percent of the worldâ€™s greenhouse gas emissions, have deposited their instruments of ratification.
Obama welcomed the news with a special address in the Rose Garden.
â€œToday, the world meets the moment,â€ Obama said. â€œAnd if we follow through on the commitments that this Paris agreement embodies, history may well judge it as a turning point for our planet.â€
The Paris agreement commits rich and poor countries to take action to curb the rise in global temperatures that is melting glaciers, raising sea levels and shifting rainfall patterns. It requires governments to present national plans to reduce emissions to limit global temperature rise to well below 2 degrees Celsius (3.6 degrees Fahrenheit).
While the targets in the agreement are not legally binding, the treaty does require countries to report on emissions and their progress on reaching the goals in the national climate plans they submitted to the UN The countries are also required to maintain those plans, update them every five years and to pursue measures to implement their stated goals.
â€œItâ€™s clearly a momentous moment in terms of global action on climate change,â€ said David Waskow, international climate director at World Resources Institute. â€œThis has been much more rapid than anticipated and demonstrates political support for the agreement.â€
The accord, which was adopted by consensus on Dec. 12, 2015, has entered into force at what is considered record speed for international diplomacy, reflecting a sense of urgency in the fight against global warming and a desire to seal the deal before Ban and Obama leave office.
Democratic presidential candidate Hillary Clinton supports the accord, while Republican Donald Trump opposes it.
International momentum had been building to ensure that the deal could enter force before the next UN climate conference, which starts Nov. 7 in Marrakech, Morocco.
Moroccoâ€™s Ambassador of Multilateral Negotiations Aziz Mekouar said with the treaty entering into force Marrakech will now host the first Conference of Parties to the Paris agreement.
â€œLast year, it was an historic event,â€ Mekouar said, referring to the conference where the agreement was first adopted. â€œThis year, itâ€™s even more of an historic event.â€
Michael Oppenheimer, a professor of geosciences at Princeton University, warned, however, that thereâ€™s still a long road ahead.
â€œThereâ€™s a lot of hard work ahead to fulfill the main Paris goal, avoiding dangerous climate change. Without focused efforts starting now, we are not going to avoid falling over a very steep cliff,â€ Oppenheimer said in an email.
