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.  The Paris Agreement is an environmental agreement that was adopted in 2015 by almost all nations to address climate change and its negative consequences. The agreement aims to significantly reduce global greenhouse gas emissions in order to limit global temperature increase to 2 degrees Celsius above pre-industrial levels this century, while continuing to pursue ways to limit the increase to 1.5 degrees. The agreement provides for the commitment of all major emitters to reduce their pollution from climate change and to strengthen these commitments over time. It provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts and establishes a framework for monitoring, reporting and strengthening countries` individual and collective climate goals. “A safer, safer, more prosperous and freer world.” In December 2015, President Barack Obama envisioned leaving today`s children when he announced that the United States, along with nearly 200 other countries, had committed to the Paris Climate Agreement, an ambitious global action plan to combat climate change. 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. If the United States joined the agreement, it would be technically necessary to implement an NDC within 30 days. The agreement stated that it would only enter into force (and therefore fully effective) if 55 countries that produce at least 55% of global greenhouse gas emissions (according to a list drawn up in 2015)  ratify, accept, approve or adhere to the agreement.
  On April 1, 2016, the United States and China, which together account for nearly 40% of global emissions, issued a joint statement confirming that the two countries would sign the Paris climate agreement.  175 contracting parties (174 states and the European Union) signed the agreement on the first day of its signing.   On the same day, more than 20 countries announced plans to join the accession as soon as possible in 2016.
