Yarrow Axford, PhD

About

Earth is endlessly fascinating – and we all live here.

My writing and lectures draw on 15 years as a professor investigating our planet’s climate history. I’m best known for my research in the Arctic, especially Greenland.

As an endowed professor at Northwestern, I directed a busy research group and taught fundamental science and science communication. In 2025, I stepped back from teaching to focus on my family and health. As I continue to conduct research, I’m also working to share the magic and adventure of science, and its urgent lessons from Earth’s deep past.

Speaking

The world needs insights from Earth science, now more than ever.

Overview of Public Engagement

My opinion pieces have appeared in outlets ranging from Science and American Scientist to U.S. News & World Report. I have briefed members of Congress; delivered talks at corporate events, libraries, and pubs; and given live and recorded radio and TV interviews. Outlets including the New York Times, CNN, The Independent, New Scientist, and Bloomberg News have featured my lab’s research, and I give frequent media interviews on broader scientific subjects. In 2024, the national organization Graduate Women in Science honored me with their highest award for science communication.

Professional Background

For 15 years, I taught courses on Quaternary geology, paleoclimate, energy and climate change, Earth surface processes, polar environments, and science communication at Northwestern University, where I was William Deering Professor in Geological Sciences. I directed a research group focused on past climate change. Our work was motivated by the question: “What can we learn from Earth’s past that will shed light on the future?”

I have led, planned, or joined research expeditions in the Arctic (from Alaska to Iceland) and U.S. “lower 48” for about 25 years. Recently I have focused on Kalaallit Nunaat (known in English as Greenland), where the Northern Hemisphere’s only continent-scale ice sheet is beginning to alter global sea level.

Now I’ve relocated to Boston and am Adjunct Professor at Northwestern. I continue to conduct research, and increasingly am writing for and speaking to the public and policymakers about science and our shared climate future.

An abbreviated CV [pdf] shares some specifics.

Scientific Publications

Access my work via my Google Scholar profile.

I have authored or coauthored >65 peer-reviewed journal articles and >150 conference presentations. Most have described innovations in methods for decoding past climates, or presented climate reconstructions from Iceland, Greenland, Arctic Canada, Alaska, the U.S. Midwest, or New England. In nerd terms, I am a Quaternary geologist and paleolimnologist with a focus on late glacial and Holocene paleoecology and stable isotope geochemistry. Bottom line: I love playing detective and finding clues in old mud. And those clues illuminate the path ahead, in our rapidly warming modern world.

Gratitude

The people of the Arctic, especially Kalaallit Nunaat (aka Greenland), have generously welcomed my team to their homelands to conduct research. From the bottom of my heart: thank you! And you have my profound respect – as I discuss further in this 2026 op ed.

Students and staff at Northwestern make the research happen. Thirty talented undergraduates have done great work in my lab and simultaneously given me great hope for the future. Current and past graduate students – Jamie McFarlin, Everett Lasher, Laura Larocca, Pete Puleo, Bailey Nash, Mia Tuccillo, Aidan Burdick – you are amazing.

And a huge thank you to our funders for supporting fundamental science: the U.S. National Science Foundation, Northwestern, and the National Geographic Society.
