What can ancient rocks teach us about the climate future we're hurtling toward?

In this inspiring episode, I speak with Dr. Maria Luisa Sanchez Montes, climate scientist, explorer, and creative problem-solver. Marisa takes us deep into Earth’s history through ocean sediments and plant lipids, showing how our current emissions mirror climates not seen for millions of years.

But her story doesn’t stop in the lab. With a career that spans academic excellence, IPCC contributions, and innovative microbial research, Marisa has now turned her focus toward tangible, people-powered solutions to reimagining sustainable clothing. She shares a rich and emotional journey of scientific discovery, disillusionment, courage, and a hopeful pivot toward creativity and impact.

Together, we explore:

* What plant molecules in rocks reveal about Earth's deep past

* How her climate research informed the latest IPCC report

* The emotional toll of working on the climate crisis

* Why Marisa left academia to create real-world solutions

* Her vision of a more loving, just, and sustainable future in 2075

In this episode, we talk about stones, microbes, fashion, and what it means to shape a career guided by wonder—and impact.

“Rocks and trees are like books, and I wanted to read them all to understand this earth I am living on.”
