Ruth DeFries
Ruth DeFries is a professor of ecology and sustainable development at Columbia University in New York. She uses images from satellites and field surveys to examine how the world’s demands for food and other resources are changing land use throughout the tropics. Her research quantifies how these land use changes affect climate, biodiversity and other ecosystem services, as well as human development. A particular focus of her work is in the globally-important tiger landscape of central India, with research that underpins management approaches to reconcile needs of both people and wildlife. She has also developed innovative education programs in sustainable development. DeFries was elected as a member of the U.S. National Academy of Sciences, one of the country’s highest scientific honors, received a MacArthur “genius” award, and is the recipient of many other honors for her scientific research. In addition to over 100 scientific papers, she is committed to communicating the nuances and complexities of sustainable development to popular audiences through her books “The Big Ratchet: How Humanity Thrives in the Face of Natural Crisis” and “What Would Nature Do?: A Guide for Our Uncertain Times”.
Anthony (Tony) Jackson
Anthony Jackson is recently retired from leading the Center for Global Education at Asia Society, which strives to enable all students to graduate from high school prepared for college, work in the global economy, and 21st century global citizenship. The Center is a platform for advancing education and global competence for all youth through empowering professional development of teachers and school heads, systemic change and public engagement. While heading the Center, Jackson founded the International Studies Schools Network, a global network of schools dedicated to developing students’ global competence, which now operates as a program of Community Catalyst Partners, LLC. He also founded the Global Cities Education Network, which now at Digital Promise continues the work started at the Center to engage leaders from high performing school systems worldwide in discussion and collaborative problem solving. Trained in both developmental psychology and education, Jackson is one of the nation’s leading experts on secondary school education reform and adolescent development. Jackson directed the Carnegie Corporation’s Task Force on the Education of Young Adolescents which produced the groundbreaking report Turning Points: Educating Adolescents in the 21st Century, and co-authored the seminal follow-up blueprint Turning Points 2000, considered one of the most influential books on middle school reform. He co-authored, with CRE member Veronica Boix-Mansilla, the book Educating for Global Competence: Preparing Our Youth to Engage the World, a second edition of which will be published in the fall of 2022.

Andrew (Andy) Revkin
Andrew Revkin is one of America’s most honored, experienced and innovative journalists focused on environmental and human sustainability. In 2019, he became the founding director of the Initiative on Communication and Sustainability at Columbia University’s Earth Institute (now the Climate School). There he is building programs, tools and collaborations aimed at bridging gaps between science and society to cut climate risk and spread social and ecological resilience. He runs a popular online webcast through Columbia called Sustain What and writes a related newsletter with thousands of subscribers. Before moving to Columbia, he was the strategic adviser for environmental journalism at the Society, where he helped expand the Society’s grants and programs fostering effective conservation communication where it’s needed most. From 2016 through early 2018, he was the senior reporter for climate change at the nonprofit investigative newsroom ProPublica. From 2010 through 2016 he wrote his award-winning Dot Earth blog for The Times Opinion section while serving as Senior Fellow for Environmental Understanding at Pace University. There, he developed and taught a graduate course called “Blogging a Better Planet” and co-created an award-winning field course on environmental filmmaking. He was a staff reporter at The Times from 1995 through 2009, covering issues ranging from threats to New York City’s water supply to the devastating Indian Ocean tsunami and, of course, climate science and policy. He made three Arctic reporting trips and was the first Times reporter to file stories, video and photos from the sea ice around the North Pole. Revkin began reporting on climate change in the 1980s in magazines and never stopped. He has won the top awards in science journalism multiple times, along with a Guggenheim Fellowship and Investigative Reporters & Editors Award. He has written acclaimed and award-winning books on the Anthropocene era (with National Geographic photographer George Steinmetz), the history of humanity’s relationship with weather, the changing Arctic, global warming and the assault on the Amazon rain forest, as well as three book chapters on science communication.
Revkin has crossed over into scientific scholarship. He played an early role in the evolution of the hypothesis that humans have triggered a new geological epoch, the Anthropocene. In his 1992 global warming book, he wrote: “Perhaps earth scientists of the future will name this new post-Holocene period for its causative element – for us. We are entering an age that might someday be referred to as, say, the Anthrocene [sic]. After all, it is a geological age of our own making.” That future arrived just eight years later, in 2000, when scientists formally proposed such an epoch. Revkin was invited to join the Working Group on the Anthropocene advising the International Commission on Stratigraphy and served from 2011 through 2016.
A lifelong musician, he was a frequent accompanist of folk legend Pete Seeger and Revkin’s 2013 album of original songs was called a “tasty mix of roots goulash” by a reviewer for the music site Jambands.
He lives on the coast of Maine near Acadia National Park with his wife, the sustainability educator Lisa Mechaley.
