The Paris Agreement is the first legally binding universal global agreement on climate change adopted at the Paris Climate Change Conference (COP21) in December 2015. Adaptation issues were at the forefront of the paris agreement. Collective long-term adaptation objectives are included in the agreement and countries must be accountable for their adaptation measures, making adaptation a parallel element of the mitigation agreement.  Adaptation objectives focus on improving adaptive capacity, resilience and vulnerability limitation.

Meanwhile, thousands of heads of state and government have intervened across the country to fill the void created by the lack of federal climate leadership, reflecting the will of the vast majority of Americans who support the Paris agreement. City and state officials, business leaders, universities and individuals included a base amount to participate in initiatives such as America`s Pledge, the United States Climate Alliance, We Are Still In and the American Cities Climate Challenge. Complementary and sometimes overlapping movements aim to deepen and accelerate efforts to combat climate change at the local, regional and national levels. Each of these efforts focuses on the willingness of the United States to work toward the goals of the Paris Agreement, despite Trump`s attempts to lead the country in the opposite direction. On October 5, 2016, when the agreement reached enough signatures to cross the threshold, U.S. President Barack Obama said, “Even if we achieve all the goals… we will only get to part of where we need to go. He also said that “this agreement will help delay or avoid some of the worst consequences of climate change.” It will help other nations reduce their emissions over time and set bolder goals as technology progresses, all under a strong transparency system that will allow each nation to assess the progress of all other nations.   On November 4, 2019, the United States notified the custodian of its withdrawal from the agreement, which was to take effect exactly one year after that date.
 These rules of transparency and accountability are similar to those in other international agreements. Although the system does not include financial sanctions, the requirements are intended to easily monitor the progress of individual nations and promote a sense of overall group pressure, discouraging any towing of feet among countries that might consider it.
