There is something extraordinary about being in New York in September. For a few days, the city becomes a meeting place for the world. Leaders, diplomats, civil society organizations, businesses, young people, activists, faith-based organizations, researchers and communities come together to discuss the challenges facing humanity.
This year, two major global conversations are taking place side by side: Climate Week NYC, from September 20 to 27, and the high-level week of the 81st United Nations General Assembly. Climate Week brings more than 1,000 events across New York, while world leaders gather at the United Nations from September 22 for the General Debate and a series of high-level meetings.
The proximity of these two moments invites a question: What happens when the climate conversation in the city meets the political conversation inside the United Nations?
Perhaps the answer is that the two conversations are not really separate.
Climate change is about people
Climate change is often discussed through numbers: degrees of warming, tons of emissions, percentages of renewable energy, financial commitments and targets. All of these are important. But behind every number there is a human being. Climate change affects where people can live, whether they have access to water, whether their homes are safe, whether food is affordable, whether they can work, and whether communities can remain in the places where generations have lived. This is why climate conversation cannot be separated from the conversation about poverty, inequality, housing, health, water and human dignity.
Climate Week’s 2026 program itself reflects this interconnectedness. Its themes include buildings and infrastructure, climate and health, environmental justice, sustainable cities and communities, energy, food and agriculture, and policy and governance.
Extreme heat is not simply a temperature statistic when there is no safe place to shelter. Heavy rain is not simply a weather event when there is nowhere dry to sleep. Lack of access to water and sanitation is not merely an infrastructure problem when a person is already living on the margins of society. The climate crisis can deepen existing vulnerabilities.
Two worlds meeting in one city
During these September days, one can almost feel two worlds meeting in New York. Inside the United Nations, governments discuss international cooperation, sustainable development, climate action and the future of multilateralism. Across the city, Climate Week creates spaces for businesses, communities, civil society, innovators, young people and many others to ask what climate action can look like in practice. The UN’s Climate Summit on September 23 is particularly significant. Ten years after the Paris Agreement, the Summit is intended to strengthen cooperation, accelerate the energy transition, advance climate justice and protect people from an accelerating climate crisis. The challenge is to connect these conversations.
Global commitments need local voices.
Policies designed at international level eventually must become realities in neighborhoods, cities and communities. And communities should not only be the recipients of decisions. They need to be part of shaping them.
Who is sitting at the table?
This question has become increasingly important in my own experience of being connected to the UN. The UN is a place where nations come together. But the words of the Charter begin with something even more fundamental: “We the peoples.” The UN’s High-Level Week 2026 itself recalls this phrase while emphasizing cooperation, peace, dignity, equality and a healthy planet. Who, then, are the people we mean?
We mean the people living in cities and rural communities: young people and older people, people with disabilities, indigenous peoples, migrants and refugees, people experiencing poverty, people experiencing homelessness, people whose communities are already confronting the consequences of environmental change. Their experience is not an addition to the climate conversation. It is part of the evidence we need.
A person who has experienced homelessness may see solutions that are invisible from a conference room. A community living with water insecurity understands the meaning of water in ways that cannot be captured by a policy document alone. A young person growing up in a neighborhood affected by pollution can speak about environmental justice from lived experience. Listening to these voices does not replace scientific knowledge, policy expertise or governmental responsibility. It strengthens them.
The SDGs remind us that nothing happens in isolation
The Sustainable Development Goals were never intended to be seventeen isolated compartments. Water is connected to health. Health is connected to housing. Housing is connected to energy. Energy is connected to climate. Climate is connected to poverty and inequality. Cities are connected to all of them. And partnerships are necessary to bring these different dimensions together.
From commitments to dignity
Perhaps this is one of the most important questions for Climate Week and the General Assembly alike: How do we move from commitment to transformation?
The Climate Week organizers describe the 2026 program as a space for moving toward implementation, bringing together governments, businesses, communities and individuals.
The United Nations Climate Summit is similarly focused on accelerating action at a critical moment. But implementation ultimately has to be measured in human terms. Can people drink safe water? Can they find a safe and affordable place to live? Can they access clean energy? Can they remain healthy? Can they participate in decisions affecting their lives? Can a person who has been pushed to the margins regain a sense of belonging and dignity? These are climate questions, development questions and human rights questions at the same time.
From New York to the world
There will be many speeches during these days. There will be negotiations, panels, announcements, commitments, photographs and moments of celebration. And there should be. The world needs spaces where people can come together and imagine solutions to problems that no country can solve alone. But perhaps the real test begins after the meetings end. The test is whether the conversations taking place in New York reach communities far beyond New York. Whether global commitments become local action. Whether the voices of people living at the margins reach the tables where decisions are made. Whether climate action protects not only the planet, but the people who depend upon it.
Standing in New York during Climate Week and the General Assembly, it is impossible not to be reminded that the climate crisis is ultimately a question of the kind of world we want to build together.
A world where no one is left without water.
Where no one is denied a safe place to live.
Where communities have a voice in decisions that affect their future.
Where development does not leave the most vulnerable behind.
And where climate action is measured not only by what governments promise, but by whether those promises help restore dignity, hope and belonging to people and communities.
The world may gather in New York for a week, but the real work begins when everyone goes home.
