If it had decided to withdraw from the UNFCCC, it could be terminated immediately (the UNFCCC entered into force for the United States in 1994) and enter into force a year later. On August 4, 2017, the Trump administration officially communicated to the United Nations that the United States intends to withdraw from the Paris Agreement as soon as it has the legal right to do so.  The invitation to resign could only be presented after the agreement entered into force for the United States for three years in 2019.   On 4 November 2019, the United States notified the depositary of its withdrawal from the agreement, which is to take effect exactly one year after that date.  The Paris Agreement is an agreement under the United Nations Framework Convention on Climate Change (UNFCCC) that addresses the reduction, adaptation and financing of greenhouse gas emissions from 2020 on or after 2020. The agreement aims to address the global threat of climate change by maintaining a global temperature increase well below 2 degrees Celsius this century and continuing efforts to further limit the temperature increase to 1.5 degrees Celsius.  South Korea is expected to quit coal by 2029 and stop funding coal projects in other Asian countries aimed at limiting greenhouse gas emissions under the Paris climate agreement, a research group said Thursday. . . .
