Currently, 197 countries – every nation on earth, the last signatory is war-torn Syria – have adopted the Paris Agreement. 179 of them have consolidated their climate proposals with official approval, including, for the time being, the United States. The only major emitters that have yet to formally accede to the agreement are Russia, Turkey and Iran. It will also enable the contracting parties to gradually strengthen their contributions to the fight against climate change in order to achieve the long-term objectives of the agreement. The Paris Agreement was launched at the signing on April 22, 2016 (Earth Day) at a ceremony in New York.  After the agreement was ratified by several EU member states in October 2016, there were enough countries that had ratified the agreement to produce enough greenhouse gases in the world for the agreement to enter into force.  The agreement came into force on November 4, 2016.  The United States played an important role in the organization and negotiation of the Paris Agreement and signed it in 2015. As one of its signatories, the United States has committed to reducing emissions by 26-28% by 2025 from 1990 levels. However, in 2017, the federal government announced its intention to withdraw from the agreement after a new government took office, and on November 4, 2020, the United States became the only nation to withdraw.
It is in this context that a group of 195 countries (mostly all countries in the world) adopted the agreement in 2015 at the United Nations Conference on the Development of Democracy and Democracy (COP21). It is the first binding universal global climate agreement (art-of) that contains a global action plan to get the world on track to avoid the worst effects of global warming. While mitigation and adjustment require more climate funding, adjustment has generally received less support and has mobilized fewer private sector actions.  A 2014 OECD report showed that in 2014, only 16% of the world`s financial resources were devoted to adaptation to climate change.  The Paris Agreement called for a balance between climate finance between adaptation and mitigation, highlighting in particular the need to strengthen support for adaptation from the parties most affected by climate change, including least developed countries and small island developing states. The agreement also reminds the parties of the importance of public subsidies, as adjustment measures receive less public sector investment.  John Kerry, as Secretary of State, announced that the United States would double its grant-based adjustment funding by 2020.  Since Trump`s announcement, U.S.
envoys continue to be – as for the record – at the United Nations Plus.
