The government argues that the probability of a catastrophic increase in global temperature is justified by the erosion of fuel efficiency standards. Yes, you read it right. The contributions each country should make to the global goal are defined by that country and designated as national contributions (CNN).  Article 3 states that they are “ambitious,” “a progression over time” and defined “in order to achieve the objective of this agreement.” Contributions are recorded every five years and recorded by the UNFCCC secretariat.  Any additional ambition should be more ambitious than the previous one, known as “progress.”  Countries can cooperate and pool their national contributions. The planned contributions at the national level, which were promised at the 2015 climate change conference, serve, unless otherwise indicated, to an initial contribution at the national level. COP 21 or the Paris Climate Conference have resulted in a new international climate agreement that applies to all countries and aims to keep global warming below 2 degrees Celsius, in line with the recommendations of the Intergovernmental Panel on Climate Change (IPCC). The president`s promise to renegotiate the international climate agreement has always been a smokescreen, the oil industry has a red phone at the Home Office, and will Trump bring food trucks to Old Faithful? The goal of avoiding what scientists consider to be a dangerous and irreversible scale of climate change – which is achieved with warming of about 2oC during pre-industrial periods – is of paramount importance to the agreement. From 30 November to 11 December 2015, France hosted representatives from 196 countries at the end of the Un Climate Change Conference (UN), one of the largest and most ambitious global meetings ever held. The goal was nothing less than a binding and universal agreement to limit greenhouse gas emissions to levels that would prevent global temperatures from rising more than 2oC above the lower temperature levels set before the start of the industrial revolution. This is part of the Paris Agreement`s efforts to “reduce” emissions. Since analysts agreed in 2014 that CNN would not limit temperature rise below 2 degrees Celsius, the global inventory again brings the parties together to assess the evolution of their new CNN to permanently reflect a country`s “highest possible ambitions.”  As host and president of COP21, France is committed to supporting a multilateral negotiation process and listening to all parties involved in reaching an agreement that says “A safer, safer, more prosperous and freer world.” In December 2015, President Barack Obama envisioned leaving today`s children when he announced that the United States, along with nearly 200 other countries, had committed to the Paris Climate Agreement, an ambitious global action plan to combat climate change.
