Since the beginning of the industrial era, according to NPR, the United States has been responsible for a greater greenhouse gas emissions than any other country, and the signing of the agreement marked the nation`s commitment to reducing that burden on the world as a whole. However, the Trump administration has fundamentally reversed that position by withdrawing from the agreement and withdrawing the policy of regulating domestic emissions, Scientific American reported. “Abandoning the Paris agreement is cruel for future generations,” said Andrew Steer, president and CEO of the World Resources Institute, about the Trump administration`s decision to formally withdraw the United States from the agreement. The U.S. will lose much stronger jobs and economy that will bring a low-carbon future, Steer said in a statement. 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 EU and its member states are individually responsible for ratifying the Paris Agreement. There was a strong preference for the EU and its 28 Member States to simultaneously table their ratification instruments to ensure that neither the EU nor its Member States commit to commitments that belong exclusively to the other and there was concern that there was a disagreement on each Member State`s share of the EU-wide reduction target. just as Britain`s vote to leave the EU could delay the Paris pact.  However, on 4 October 2016, the European Parliament approved the ratification of the Paris Agreement and the EU tabled its ratification instruments on 5 October 2016 with several EU Member States.
 Adaptation issues were at the forefront of the paris agreement.
