This week, New York City is once again becoming the world’s stage for climate action. From September 21st to 29th, Climate Week NYC 2025 will bring together leaders, scientists, activists, artists, and everyday New Yorkers for a week filled with conversations, marches, exhibits, and community events dedicated to tackling the climate crisis. With over 500 events spread across the five boroughs, it’s one of the largest gatherings of its kind anywhere in the world.

Why Climate Week Matters

Climate Week NYC happens alongside the United Nations General Assembly, which means many of the world’s most important decision-makers are already in the city. But it’s not just about politics and diplomacy. The week is designed to connect global challenges with local action, showing how communities – from public housing residents to schoolchildren – can be part of the solutions. With New York already experiencing flooding, extreme heat, and worsening air quality, the stakes couldn’t be higher.

Events You Shouldn’t Miss

Here are some of the most anticipated events, from scientist discussion panels to grassroots events:

• Opening Ceremony (Sept 23, Times Center): The official kick-off will feature Governor Kathy Hochul, UN climate officials, and youth leaders. Dr. Katharine Hayhoe, one of the world’s leading climate scientists and communicators, is delivering a keynote address that promises to be both eye-opening and inspiring.
• The Climate Justice March (Sept 22): Tens of thousands of New Yorkers are expected to march through Manhattan, demanding stronger action from governments and corporations. This is one of the most visible and powerful expressions of grassroots climate activism you’ll see all year.
• The Hub Live (Sept 24–25, Midtown): A gathering spot where businesses, nonprofits, and policy leaders discuss everything from renewable energy to sustainable cities. While some sessions are invite-only, the discussions will help shape climate action for years to come.
• American Museum of Natural History (Sept 25–26): AMNH is reimagining its iconic dioramas to show the impacts of climate change on ecosystems. Special events include Climate Resilience in Action on Sept 25, blending science with art and storytelling, and Climate Education in Action on Sept 26, featuring a keynote by Katharine Hayhoe.
• New York Botanical Garden (Sept 21 & Sept 24): Start the week with a 5K Fun Run at NYBG, or join the panel Rooted in Resilience: Harnessing Nature for Climate Solutions on Sept 24, which brings together experts on conservation and restoration. Admission is free for some climate-focused events.
• Brooklyn Botanic Garden (Sept 23): Hosting the NYCHA Resident Climate Action Grants Showcase, this event highlights resident-led sustainability projects in public housing—a reminder that climate solutions can start right at the neighborhood level.

Who’s Leading the Conversation

• Dr. Katharine Hayhoe: Known for making climate science accessible and human-centered, her talks are consistently some of the most anticipated of the week.
• Christiana Figueres: Architect of the Paris Agreement, bringing a global perspective on how cooperation can drive progress.
• Mayor Eric Adams & NYC Officials: Highlighting city-led initiatives, from cooling centers to green transportation, and unveiling new projects to make New York more resilient.

City and State Involvement

Expect to hear new announcements from Governor Hochul about clean energy investments and from Mayor Adams on climate justice and resilience projects. Topics will range from preparing neighborhoods for extreme heat to protecting coastal communities from rising seas.
