“There's a reason why we keep inviting Seth back for speaking engagements: he is consistently incisive, engaging, motivating, and a wealth of knowledge on climate change, social justice issues, and more. It's no surprise he was the top-rated speaker at our most recent conference—and it's absolutely essential that more people learn from his lifetime of wisdom and advocacy.”
– Dr. Melissa Lem, Past President, Canadian Association of Physicians for the Environment
"Seth's work, particularly his 6 Markers framework, has been foundational to my organizing practice – both when I was leading 350.org's Canada team and teaching in Seneca's Government Relations program. He has a rare gift for making transformational policy ideas not just digestible but actionable, helping people understand what genuine climate emergency response actually looks like and how to push for it. His voice is exactly what we need right now to move the conversation beyond incrementalism toward real climate mobilization. "
– Amara Possian, former Canada Lead for 350.org
“Seth is an incredibly engaging speaker with a wealth of knowledge about climate policy. Students, many of whom are used to hearing grim predictions about their future, are energized and inspired by his ‘we can do this, we have done it before’ approach to mobilizing for a clean and just world. I would highly recommend him as a guest speaker in secondary and post-secondary classrooms.”
– Prof. Kyla Tienhaara, Canada Research Chair in Economy and Environment, Queens University
“I had the privilege of hosting Seth Klein to speak during our Remembrance Day service at Canadian Memorial United Church, and he was excellent. He met the moment with careful preparation, intellectual rigour, and deep attentiveness to context, bringing depth of knowledge to the climate crisis while translating complexity into language that is both accessible and compelling. If you’re looking for a speaker who does the homework, understands context, and can move people with clarity and heart, I recommend Seth without hesitation.”
– Rev. Beth Hayward

Yet Seth Klein stood out even in this august company and contributed greatly to the success of our 2023 festival. He brought a perspective and expertise on the climate issue that was incomparable.
