The UN General Assembly, or UNGA, kicks off this week in New York with climate change at the top of the agenda.
Teenage climate activist, Greta Thunberg, will be bringing her star-power to proceedings.
However with 193 countries represented and an increasing amount of local, regional and global pressures pushing for attention, the agenda is far from certain.
US President Donald Trump is speaking to the assembly and Iran's President Hasan Rouhani expected to make the trip.
India's Prime Minister Narindra Modi is attending as is Pakistan's Prime Minister Imran Khan and both will have Kashmir front and centre of any conversation.
While China's President Xi Jinping and Russia's Vladimir Putin are not expected it is unlikely that the countries will not be represented at any top table discussions.
With the Middle East, migrants and Brexit: UNGA has a lot to talk about.
