Ban calls on world leaders to act on climate changeListen /
World leaders are being urged by the UN Secretary-General to move from "words to deeds" when it comes to climate change.
More than 190 countries agreed last December to limit global temperature rises due to carbon emissions, to less than 2 degrees Celsius.
Jocelyne Sambira reports.
A high-level signing ceremony for the universal deal has been convened by Ban Ki-moon for 22 April at UN headquarters in New York.
The participation of Heads of State and Government, Ban insisted, would show the world how engaged and committed they were.
"This agreement provides a solid foundation for the low carbon climate resilient transformation of the global economy. It will help secure a future that is safer, healthier and more prosperous for all people. But our task is not over. In fact, it has just begun. In 2016, we must go from words to deeds. The 22 April signature ceremony is an essential step."
Countries will need to adopt the agreement within their own legal systems first.
The Paris agreement will enter into force when ratified by at least 55 countries, which together represent at least 55 per cent of global emissions.
Media reports say the island nation of Fiji has become the first country to ratify the Paris climate change agreement.
