Nearly 150 nations are planning to attend the United Nations climate agreement signing ceremony on April 22 at the UN Headquarters in New York.
There are currently 147 confirmed countries for the signing ceremony, which include approximately 50 heads of state.
The April 22 event is a testament to the momentum set during COP21 or Paris Climate Change Conference held in December 2015. During this historic gathering, world leaders hammered out the consolidated global efforts on how to address global warming.
"That means that momentum for the Paris accord has not subsided," said Segolene Royal, the environment minister of France and UN climate change process.
Royal added that the April 22 ceremony should give world leaders the chance to announce a firm statement on carbon pricing policy. These individual statements should aim to set an "elevated, stable, discernible and coordinated" carbon policy that can help develop clean energy.
The attending countries list includes the world's biggest emitters of greenhouse gases - United States, China, India, Japan, Australia, Brazil, Italy, United Kingdom, Spain, France and Germany.
U.S. President Barack Obama will be going on a fence-mending mission with ally Saudi Arabia during the week of the UN signing ceremony. Washington has yet to announce his representative for the April 22 signing event.
UN Secretary-General Ban Ki-moon highlighted that the signing ceremony is merely the first step in pushing forward the global efforts to address climate change.
The climate agreement pushes for the significant reduction of global greenhouse gases from participating countries. The goal of this worldwide effort is to keep the global warming levels at "well under 2 degrees Celsius," which is comparable to pre-industrial times, by 2050.
The collective effort also includes limiting the rise in temperature to 1.5 degrees Celsius. The participating countries are also required to submit updated climate action plans every five years.
To mark the historic day, the UN is also launching a global social media tree-planting event on April 22. To join, people can do any of the three activities - plant a tree in their backyards, hug a full-grown tree or sketch or take a photo of their favorite tree.
You can post status messages or images on any social media platform and use hashtags #ParisAgreement, #Trees4Earth and #EarthDay2016.
"The link between the Paris Agreement and trees is clear - forests will be key allies for combating climate change and meeting the long-term goal of restoring the ecological balance of planet Earth by the second half of the century," wrote UN on its website.
