Parallels of ecological impacts of climate change in Arctic and Andean regions are revealed on glaciological research expeditions in Chile, Alaska, Iceland and Peru.
Cresta Alta follows the commitment of scientists who travel deep into the wilderness to gather field data that informs our collective understanding of climate change impacts on our planet. Sustainability initiatives in these same locations offer insight into the potential for viable alternatives and solutions.
In Cresta Alta, join filmmaker, Todd Anders Johnson, on a 10 day backpacking expedition to the McCall Glacier in the Alaskan Arctic National Wildlife Refuge with Dr. Matt Nolan; setting up basecamp at the Gamma Glacier in the Olivares Basin, high in the Chilean Andes with Dr. Sebastian Mernild; trekking to Lake Pacacocha, situated at 15,000 feet in elevation, in the Peruvian Cordillera Blanca with Dr. Rachel Chisolm; joining the Icelandic Glaciological Society jeeping up the Vatnajökull ice cap to conduct ice core drilling and meeting with the President of Iceland to discuss his experiences and perspectives on climate change impacts in Iceland.
Cresta Alta Film Tour
The Cresta Alta Film Tour has been engaging audiences with film screenings followed by Q&A and panel discussions throughout Colorado, Alaska, Vermont, Kansas City, Cape Cod and Nantucket at theaters, museums, colleges and high schools.
PBS TV Broadcast
Cresta Alta will be broadcast on several PBS TV stations around the country this summer including KLCS in Los Angeles, RMPBS and RMPBS+ in Colorado and WPBS in New York and Ontario, Canada.
As the filming of the project unfurled, Johnson said he began to draw similarities between these initiatives and wanted the film to also highlight some of the sustainability solutions that were happening in these regions alongside the reality of how climate change was impacting these areas. One example is a United States Agency for International Development (USAID)-funded program in Huaraz, Peru, using bio-remediation to clean river water of heavy metals occurring due to deglaciation. The expeditions and their findings highlighted in the film showcase the critical roles of scientific programs and the need for continued research funding. Alongside the film, Johnson has launched the Cresta Alta Film Tour, engaging with arts councils, colleges, high schools and museums by providing a screening of the film to communities across the United States, followed by a post-film Q&A.
Cresta Alta film tour comes to Fairplay:
The Flume, By Meryl Phair
In Cresta Alta, Todd takes a more urgent approach, following scientists as they study glaciers and observe firsthand the rapid changes happening to these ecosystems. “Cresta Alta was an adventure story, a research expedition, and a personal journey all in one,” Todd said. “I wanted to tell the story of these scientists and show how their research is helping us understand the very real effects of climate change. It’s all about trying to make the science more accessible, but also making it emotionally compelling, so people can understand why this is so important.”
The Risan Project Tour: Todd Johnson Brings Environmental Advocacy to Fairbanks: The University of Alaska Fairbanks Sun Star, By Amber McCain
The Cresta Alta Film Tour is engaging audiences throughout the US and features Risan Media's expedition-based climate change documentary film titled, Cresta Alta, that chronicles a journey to Alaska, Iceland, Chile and Peru to document glaciological research expeditions and sustainability.
The screenings are followed by Risan Studies' community sustainability panel discussions and a Q&A with environmental filmmaker and socially-conscious musician, Todd Anders Johnson, who studied development issues at the University of Washington.

For the past 25 years, Dr. Matt Nolan has specialized in understanding the impacts of climate change on the landscape of Alaska and he developed fodar to facilitate that. He received an MS in Arctic Engineering at UAA in 1992, a PhD in Geophysics from UAF in 1998, and has been a research professor at UAF/INE since 1999. He has led dozens of field projects during that time, largely using equipment he built or techniques he developed to better understand our landscape and changes to it. No single investigator has acquired or made more topographic maps of Alaska than Dr Nolan, starting in 2000 with the first airborne IfSAR data in Alaska including the entire Kuparuk River basin and the largest mountain passes in Alaska to time-series of enormous lidar collections in the eastern Brooks Range to his own fodar mapping.
Ólafur Ragnar Grímsson served as President of Iceland for twenty years, 1996-2016, elected five times in nationwide elections. Previously, he was Minister of Finance, Member of Parliament, Member of the Parliamentary Assembly of the Council of Europe, and the first Professor of Political Science at the University of Iceland. He now serves as Chairman of the Arctic Circle, which he founded in 2013 with various Arctic partners.
President Grímsson served on the International Advisory Board for COP28. For decades, President Grímsson has been an active participant in the global climate dialogue and, during his Presidency and in recent years, initiated and promoted clean energy projects in Asia, Africa, the Middle East, Europe, the United States and the Americas; especially using Icelandic achievements and technologies as a model. Cooperation with Sinopec has led to the largest geothermal projects in the world, building clean energy urban heating systems in a multitude of Chinese cities. He was the Chairman of a commission established by IRENA on the new geopolitics emerging from global renewable energy transformation and served on the Advisory Board of Sustainable Energy for All, created by the United Nations and the World Bank. In addition to devoting his post-presidential efforts to the three areas of climate, the Arctic, and clean energy, Grímsson is also involved in international cooperation on the oceans and the evolution of sustainable use of marine resources.
President Grímsson has received many international awards, including the Nehru Award for International Understanding, presented to him by the President of India, and the First Class Order of Zayed II, bestowed to him by UAE President His Highness Sheikh Mohamed bin Zayed Al Nahyan for his efforts and role at COP28.

She is also working on coupling of ice sheet models with global and regional climate models. She is the author/co-author of 45 peer-reviewed papers, h-index 23 (total of 1884 citations Dec 2020).

Todd Anders Johnson is an environmental filmmaker, socially-conscious musician and educator and independently produced the Cresta Alta Film. With the Risan Brands’ family of companies, Todd merges his passions for the environment, the arts and outdoor recreation.
Todd studied international development at the University of Washington and has been a panelist and presenter with Bono’s One Campaign and with the United Nations' International Mountain Day. Todd has coordinated solar powered concert events with the Nantucket Land Council and with the City of Aspen and has established partnerships with organizations such as the Canadian Climate Project and Protect Our Winters.
Todd's film documenting his travels, his interviews with leading scientists across the world, and the amazing cinematography was a great experience for our students. There were multiple entry points for discussion, including from scientific, creative arts, geopolitical, and humanistic angles. I highly recommend Todd's work for any school looking to bring real-world examples of the impact of climate change, and what the next generation can do about it.

A must see for not just environmentalists but anyone that cares about the future and how melting glaciers will impact those that live near and far from them. Very well done movie, will see it again if able!
Stacey Bond Shinske, Albany, NY
We had a chance to watch it over the weekend and really enjoyed it. It is striking to think about how much of this research may be affected by the current restrictions on funding and the USAID closure. So much important work...
