In 2016, Trump campaigned on a promise to “denounce” the deal, which unfairly weighed on his choice over the United States and gave a passport to poor countries. The United States, second only to China in terms of THE level of pollution of CHARBON, has committed to reduce emissions by 26 to 28 percent from 2005 levels by 2025. Iran, Iraq and Libya – all members of the Organization of Petroleum Exporting Countries (Opec) – and conflict-torn states such as Yemen and South Sudan have not ratified the agreement. The bulk of the 2030 CO2 emission reduction commitments, made by 184 countries under the Paris Agreement, are far from enough to keep global warming well below 3.6 degrees Fahrenheit (2 degrees Celsius). Some countries will not meet their commitments and some of the world`s largest CO2 emitters will increase their emissions further, according to a group of world-class climate scientists. The public is increasingly involved; Millions of people took part in the global climate strikes in September. Many countries, states and provinces, cities and businesses are responding to these demands for stronger climate protection, he says. How each country is on track to meet its obligations under the Paris Agreement can be constantly monitored online (via the Climate Action Tracker  and the climate clock). The Paris Agreement is an environmental agreement that was adopted by almost all nations in 2015 to combat climate change and its negative effects. The agreement aims to significantly reduce global greenhouse gas emissions in order to limit global temperature increase to 2 degrees Celsius above pre-industrial levels this century, while continuing to pursue ways to limit the increase to 1.5 degrees. The agreement provides for the commitment of all major emitters to reduce their pollution from climate change and to strengthen these commitments over time.
It provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts and establishes a framework for monitoring, reporting and strengthening countries` individual and collective climate goals. 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.  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 memo states that the United States “could announce earlier a plan to withdraw and reduce or cease participation in the activities of the Paris Agreement.” Developed countries, while not legally required to contribute to the mitigation and adaptation efforts of developing countries, are encouraged to provide financial assistance and are held accountable for the funding they provide or are mobilized. The United States, which has always ratified the UN`s 187 list, began withdrawing from the agreement in 2019 and will withdraw on November 4 of that year. President Donald Trump doubts that greenhouse gas emissions are causing dangerous levels of global warming.
