The 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 21), held in Paris in 2015, ended with the adoption of the decision and the Paris Agreement. The agreement came into force in November 2016 and will apply from 2020. Its goal is to keep the global temperature rise well below 2 degrees Celsius. The goal is to achieve this by increasing the capacity to adapt to the negative effects of climate change and by promoting resilience to climate change and the development of low-carbon co2. To achieve the agreed objectives, the Paris Agreement establishes a strengthened transparency framework to promote mutual trust and promote effective implementation of the agreement, improve clarity and facilitate monitoring of progress. (a) to keep the global average temperature increase well below 2 degrees Celsius above pre-industrial levels and to continue efforts to limit the increase in temperature to 1.5 degrees Celsius above pre-industrial levels, the potential to significantly reduce the risks and effects of climate change; The adoption of the Paris Agreement is part of a long-standing effort by the scientific community to combat climate change. 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 long-term goal of the Paris Agreement is to keep the increase in the average global temperature at a level well below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels; and to continue efforts to limit the increase to 1.5 degrees Celsius, while acknowledging that this would significantly reduce the risks and effects of climate change.
This should require a rapid reduction in emissions to achieve “a balance between anthropogenic emissions from sources and the reduction of greenhouse gases from wells” in the second half of the 21st century. It also means increasing the parties` ability to adapt to the negative effects of climate change and “reconciling financial flows with a way to reduce greenhouse gas emissions and climate-resistant development.” The Paris Agreement is the world`s first comprehensive climate agreement.  Under U.S. law, a president may, in certain circumstances, authorize U.S. participation in an international agreement without submitting it to Congress. Whether the new agreement implements a pre-agreement, such as the UNFCCC, ratified by the Council and Senate approval, and whether it complies with existing U.S. legislation and can be implemented on that basis. Since the agreement does not contain binding emission targets or binding financial commitments beyond those of the UNFCCC and can be implemented on the basis of existing legislation, President Obama has decided to approve it through executive measures. The aim of the agreement is to reduce the global warming described in Article 2 and to implement the UNFCCC by: “The links between biodiversity, climate change and human health are now well established.
