John Cortinas was born on January 28, 1964, in Grand Island, Nebraska. John moved with his family to Omaha at a young age. There, heavy rains, winter snow, severe thunderstorms, and tornadoes inspired his fascination with the weather. That fascination became a calling in junior high school, when he took a weather class almost by chance. Though it was only his third-choice elective, the course captured him completely. “I just remember after that course, I realized there was nothing else I wanted to do than be a meteorologist.”
John grew up in a Catholic family of mixed ethnicity—his mother’s side traced to German roots, while his father’s family came from a proud Hispanic lineage. In both his household and community, traditional gender roles were strongly reinforced. Yet, his father instilled in all his children a deep pride in their Hispanic heritage, giving John an inner strength that helped him navigate those expectations and embrace being gay.
With few gay role models to look to, John turned to books from libraries and mainstream bookstores to learn about homosexuality in a positive way. After affirming his identity, he came out to a close friend and began connecting with other gay students. Before college, he ventured with friends into his first gay club in Omaha. “For the first time I felt like this felt right. This was community.”
A first-generation college graduate, John studied at Metropolitan State University of Denver and later earned his doctorate in Geophysical Sciences at Georgia Tech. Along the way, he discovered a network of LGBTQ scientists at conferences and within his field. Seeing the importance of diversity, he joined the American Meteorological Society’s Board of Women and Minorities to advocate for greater inclusion.
For ten years, he studied severe weather and developed tools to improve forecasting in Oklahoma, a conservative place at the time where sodomy laws were still on the books. Even so, John built a fulfilling life with his partner and found strength in his community of queer meteorologists. His career took a major leap when he moved to Washington, D.C., to serve as Director of NOAA’s Cooperative Institute Program. The proximity to national policymakers inspired him to expand his efforts to promote diversity in science.
In 2019, John became Director of NOAA’s Atlantic Oceanographic and Meteorological Laboratory, the first openly gay senior executive of Hispanic descent to lead a national NOAA laboratory. He later rose to Deputy Assistant Administrator, overseeing all 10 of NOAA’s national laboratories and their partner institutes.
After decades of research on severe weather and climate change, John has drawn lessons from his own advocacy. He often notes that the persistence of the LGBTQ community offers a model for addressing climate change: “to not give up in terms of understanding, learning to work with one another, holding out hope…and have an open mind.”
Now retired, John continues to champion underrepresented groups in science through interviews, mentoring, and professional organizations. He lives in Miami with his partner, his legacy firmly established as both a pioneering meteorologist and a trailblazing advocate for equity in STEM.
