After ratification, the agreement requires governments to submit their emission reduction plans. Ultimately, they must play their part in keeping global temperatures well below 2 degrees Celsius above the pre-industrial period and making “efforts” to keep them at 1.5 degrees Celsius. 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.  Almost every country in the world. Of the 195 countries that signed the Paris Agreement, 189 have formally adopted it. Nicaragua and Syria initially withdrew their support for the pact, but both eventually agreed to the agreement. The Paris Agreement provides a sustainable framework that guides global efforts for decades to come. The aim is to create a continuous cycle that prevents countries from increasing their ambitions over time. In order to encourage increased ambitions, the agreement defines two interconnected processes, each with a five-year cycle.
The first is a “comprehensive state of affairs” to assess the collective progress made in achieving the long-term goals of the agreement. The parties will then submit new NDCs “informed of the results of the global inventory.” While the agreement has been welcomed by many, including French President Francois Hollande and UN Secretary-General Ban Ki-moon, criticism has also emerged. James Hansen, a former NASA scientist and climate change expert, expressed anger that most of the agreement is made up of “promises” or goals, not firm commitments.  He called the Paris talks a fraud with “nothing, only promises” and believed that only a generalized tax on CO2 emissions, which is not part of the Paris agreement, would force CO2 emissions down fast enough to avoid the worst effects of global warming.  Turkey and three major oil-exporting nations are among the seven countries that have not yet ratified the 2015 Paris climate agreement. Angola joined Kyrgyzstan and Lebanon and ratified in 2020, meaning the 190-nation agreement was formally approved by 197 nations. If the United States pulls through, it could still have a voice in the UN climate negotiations.
