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.  President Trump is pulling us out of the Paris Climate Agreement. Countries have yet to finalise the rules for the operation of the Paris Agreement, and COP26, scheduled for the UK in November 2021, will allow countries to carry out this task. WWF is working with U.S. leaders engaged in managing the climate crisis to show at COP26 that the United States will play its part. The agreement commits all countries to reduce their emissions and cooperate to adapt to the effects of climate change and calls on countries to strengthen their commitments over time. The agreement provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts, while establishing a framework for monitoring and reporting transparently on developing countries` climate goals.
The Paris Agreement is the first truly comprehensive commitment to the fight against the climate crisis. In 2015, 195 countries and the European Union signed a single comprehensive agreement to keep global warming well below 2 degrees Celsius – and to do everything in its power to exceed 1.5 degrees Celsius. The pioneering agreement was successful where previous attempts failed because each country set its own emission reduction targets and adopted its own strategies to achieve them. In addition, nations, inspired by the actions of local and regional governments, businesses and others, have recognized that the fight against climate change brings considerable socio-economic benefits. The Paris Agreement is an agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the reduction, adaptation and financing of greenhouse gas emissions from 2020. The agreement aims to address the threat of global climate change by keeping global temperatures well below 2 degrees Celsius above pre-industrial levels this century and to continue efforts to further limit the temperature increase to 1.5 degrees Celsius.  The UN report warns that the terrible effects of climate change will come sooner than expected. This is why we need to follow the report`s advice and why every tonne of emissions reduction can make a difference. The president`s promise to renegotiate the international climate agreement has always been a smokescreen, the oil industry has a red phone at the Home Office, and will Trump bring food trucks to Old Faithful? Finally, instead of giving China and India a passport to pollution, as Trump asserts, the pact is the first time these two major developing countries have agreed on concrete and ambitious climate commitments.
