Explore Summer 2025 Pre-College Program at the Columbia Climate School 🌎

Columbia Climate School in the Green Mountains is a 2-week campus-based program for high school students taking place from June 29 to July 11, 2025 in Castleton, Vermont to mobilize action and drive impact in response to our warming planet. Students will complete the program feeling empowered to address a climate challenge in their own communities.

Watch the mini-documentary Empowering Youth to Lead Climate Solutions and see how we're inspiring the next generation of changemakers.

Don’t wait for change — lead it!

Hudson River Field Station

Community Science Programs at the Field Station

Get involved in our community science projects to learn more about local research, be part of a community, build an appreciation for the natural environment, and work outdoors conducting field work! Programs include easter oyster monitoring, fish diversity and abundance, microplastic survey, plankton survey, marine debris survey, and water quality monitoring. 

Upcoming Events at the Field Station

World Fish Migration Day/World Oceans Day, June 7 11am-3pm: Each year several migratory fish species move into the Hudson River as part of an annual journey toward upriver spawning locations. Lamont has partnered with the Hudson River Estuary Program to lead a day that links multiple partners in both celebrating this migration and tallying some of the species as they begin their journey. Join our Piermont Pier location to help pull a net through the water, identify some of these migratory species entering the Hudson River Estuary from the Atlantic Ocean, and learn about how the Hudson is used as a spawning habitat by a range of marine species! 

Science Saturdays: Our regular summer Science Saturday events will roll out on June 14th with a new time of 12-4pm! Join us to learn about the Hudson Estuary, get an opportunity to interact with the abundant wildlife that calls the Hudson home, participate in interactive and environmental activities and topics, and learn about the changes and challenges facing our Hudson Estuary. 

Questions about community science programs or upcoming events at the Field Station? Contact Marisa Annunziato.

Youth to Youth Education: The Power of Educational Games

Polar CAP intern Ashley Jun turned her school’s Earth Day event into an opportunity to share resources developed by our Polar CAP interns and educate her colleagues about the importance of the polar regions in Earth’s climate. Building on the Polar CAP principles to “Engage-Educate-Activate,” Ashley wanted to connect her peers with her summer experience through the  games developed by our Polar CAP interns. Games are powerful education and communication tools, blending engagement with information in a way that makes it stickier, and connecting with people of all ages. Our interns have developed a number of educational games that span from physical activities to board and card games, covering topics like polar climate, living in the polar regions, current polar research, innovation in polar science, and what we can do to lower our climate footprints. Just like last summer, our interns will be sharing their games on Science Saturdays.
