Yes, there is a broad consensus within the scientific community, although some deny that climate change is a problem, including politicians in the United States. When negotiating teams come together for international climate talks, „there is less skepticism about science and more disagreement about how to set priorities,“ says David Victor, a professor of international relations at the University of California, San Diego. The basic research is as follows: in 1992, President George H.W. Bush and 107 other heads of state adopted a series of environmental agreements at the Earth Summit in Rio, Brazil, including the UNFCCC framework, which is still in force today. The international treaty aims to prevent dangerous human intervention in the planet`s climate systems in the long term. The Pact does not set limit values for greenhouse gas emissions for individual countries and does not contain enforcement mechanisms, but rather establishes a framework for international negotiations on future agreements or protocols to set binding emission targets. Participating countries meet annually at a Conference of the Parties (COP) to assess their progress and continue discussions on how best to tackle climate change. The United States, the world`s second-largest emitter, is the only country to withdraw from the deal, a step by President Donald J. Trump, which went into effect in November 2020. Some other countries have not officially approved the deal: Angola, Eritrea, Iran, Iraq, Libya, South Sudan, Turkey and Yemen. NRDC is working to make the Global Climate Action Summit a success by inspiring more ambitious commitments for the historic 2015 agreement and strengthened initiatives to reduce pollution. Both the EU and its Member States are individually responsible for ratifying the Paris Agreement.
It has been reported that the EU and its 28 Member States are simultaneously depositing their instruments of ratification to ensure that neither the EU nor its Member States commit to obligations belonging exclusively to each other, and some feared a disagreement on each Member State`s share of the EU-wide reduction target. Just like the British vote to leave the EU, the Paris Pact could be delayed.  However, the European Parliament voted on 4 The European Union deposited its instruments of ratification on 5 October 2016 with several Member States of the European Union, on 5 October 2016.  Under the United Nations Framework Convention on Climate Change, legal instruments may be adopted to achieve the objectives of the Convention. . . .
