The war in Iran and AI governance may be dominating debate and grabbing headlines at the United Nations General Assembly, but there is also plenty of talk about climate change around New York.
UN Secretary General Antonio Guterres has been holding high-level meetings on climate action.
He has called on governments around the world to adopt concrete plans to move away from fossil fuels "with clear timelines and protection for affected workers and communities".
A few blocks away from UN headquarters, climate activists staged a fashion show on the steps of the New York Public Library with the aim of encouraging people to move away from fast fashion.
The fashion industry is one of the world’s biggest polluters and is responsible for up to 8% of global greenhouse gas emissions, according to the UN.
Models wore outfits made from recycled materials and many stitched messages and calls to action onto their garments.
"Because of all the resources - water and human resources - put behind it, fast fashion has a huge impact on the climate crisis and not a lot of people are aware of that," Pablo Amry told RTÉ News.
Mr Amry is from Mexico City and works with the grassroots organisation Sustaining All Life, which aims to help climate activists to cope with emotional stress.
To coincide with UNGA, New York Climate Week is also running in the city.
Ireland’s new youth climate delegate Adam Ó Ceallaigh travelled to New York for the events.
"Hope is essential when it comes to climate action and I have hope every time I speak to somebody else who is working on the topic," he said.
