We’re a group of nonpartisan climate scientists and mothers, working to give our children the planet they deserve.
99% of scientists agree, climate change is real. We founded Science Moms to help mothers who are concerned about their childrens’ planet, but aren’t confident in their knowledge about climate change or how they can help.
As climate scientists, we have collectively spent decades studying our earth and what human activity is doing to it. We are steeped in this reality every day and know that to solve this problem, it will take all of us moms joining forces. Together, we aim to demystify climate science and motivate everyday moms to demand climate change plans and solutions that preserve the planet for our kids.

She’s been able to take up hobbies inspired by her children’s interest and things they all enjoy doing together, such as cooking, reading, going to museums. She wishes there were more than 24 hours a day to give to both her family and science, both of which are team sports.

Dr. Joellen Russell
Dr. Joellen Russell is a Distinguished Professor and Department Head in the Department of Geosciences at the University of Arizona, where she also holds the Thomas R. Brown Distinguished Chair of Integrative Science. Joellen’s research uses robot floats, supercomputers and satellites to study the Southern Ocean and the ocean’s role in the transient global climate.
Dr. Russell is the current US Representative at the International Association for the Physical Sciences of the Oceans (IAPSO) and the former chair of the NOAA Science Advisory Board’s Climate Working Group. She teaches oceans and climate to 500-1000 students each year. Before joining UA, Prof. Russell was a Research Scientist at Princeton University and the National Ocean and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory.
Joellen is the mother of two, ages 14 and 18. Growing up in a tiny fishing village in the arctic, she was always fascinated by the ocean and knew she wanted to be an oceanographer at the age of twelve. Her children and her students’ compassion, kindness, and hard work have convinced her that when it’s their turn, we’ll all be in good hands. She hopes that her future grand-babies will understand that she did everything she could for them.

Dr. Rosimar Rios-Berrios
Dr. Rosimar Rios-Berrios is a Scientist I at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. Her research focuses on high-impact weather, especially tropical cyclones, numerical weather prediction, and precipitation extremes. Dr. Rios-Berrios also spends a great deal of her time mentoring the next generation of scientists through internships and short-term visits at NCAR.
Rosi, as most people call her, was born and raised in Puerto Rico where her family endured the devastating effects of Hurricane Maria, including many weeks without any communication and several long months without power or water. Her experience inspired her to further understand how climate change impacts extreme weather events.
She lives in Colorado now with her husband and their one-year old son, Loki. While she misses the warm, tropical days on the Island, she also enjoys living in a place with seasons and outdoor activities all year round. When she is not working, she is likely hiking, running, sewing, cooking, doing yoga or pilates, or just playing with her little one.

Dr. Claudia Benitez-Nelson
Dr. Claudia Benitez-Nelson is a Senior Associate Dean and Carolina Distinguished Professor in the College of Arts & Sciences at the University of South Carolina.

Claudia is passionate about teaching and mentoring the next generation.
Claudia has been happily married to her husband, Bryan, for almost 30 years and has two children, Noah (25) and Julia (21), who tower over their mother. It is unclear from where their musical talent is derived; however, the whole family loves the outdoors. Claudia’s favorite pastime is family vacations to any new and adventurous location (and without snow).

Dr. Irina Marinov
Dr. Irina Marinov is a climate scientist and an Associate Professor at University of Pennsylvania in Philadelphia. Irina received an Undergraduate Research Mentorship award and holds the honor of being the first woman to be tenured in the Earth and Env Sciences Dept at UPenn.
Irina uses big models and satellite data to study the role of the oceans on our climate and the impact of climate change on the oceans. She has worked on global oxygen, nutrient and carbon cycling in the ocean, phytoplankton ecology, ocean circulation and the dynamics of huge holes in the Antarctic ice called polynyas.
Irina grew up in Romania and was inspired to become a scientist by her family, who often spent time in nature. She has also been lucky to have inspiring teachers and mentors throughout her education and professional life. Before joining UPenn, Irina was a student at Middlebury College and at Princeton, a NOAA Climate and Global Change postdoctoral fellow at MIT and a postdoctoral researcher at the Woods Hole Oceanographic Institution.
Irina, her cosmologist husband, and their two boys love being part of their vibrant and diverse West Philadelphia community, and are busy on weekends discovering new pockets of nature in Pennsylvania. Sometimes she gets asked, “Aren’t you depressed to study climate change?” Her answer is always, “Absolutely not! It’s up to us to fix and heal the planet. Together we can and will do it.”

Dr. Erica Smithwick
Dr. Erica Smithwick’s research focuses on sustainable land management under climate change, with particular focus on wildfire and natural carbon storage strategies. She is a Distinguished Professor of Geography in the Department of Geography at The Pennsylvania State University, where she is also an Associate Director of the Institutes of Energy and Environment. She served as a Fulbright Scholar in South Africa and is currently an Administrative Fellow.
Erica is a mom of three children, ages 18, 16, and 9, two dogs, two cats, numerous goldfish (“won” at the local fair), and former nanny to many guinea pigs and hamsters. Erica’s love of science is coupled with a love of travel, and one of Erica’s greatest joys is inspiring that sense of adventure in her kids. When not with them or at the “Smithwick zoo,” she loves trail running with friends (one of whom re-introduced her to a hula hoop) and her pollinator garden.

Dr. Sierra Petersen
Sierra Petersen is an Assistant Professor in the Department of Earth and Environmental Sciences at the University of Michigan. She uses the chemistry of fossil seashells to understand how ocean temperatures have changed over millions of years. In 2021, Dr. Petersen was awarded the Sloan Research Fellowship for “distinguished performance and a unique potential for contributions to her field” and in 2023 she was awarded the National Science Foundation’s most prestigious award for early career researchers, the CAREER award. She has also accumulated numerous achievements for her teaching.
Sierra is a mom of two. Both children gained a love for nature through time spent in their backyard in their hometown of Ann Arbor, Michigan and through attending an all-outdoor nature preschool where they spent summers climbing trees and hiking around the UM campus, springs making their own maple syrup, and winters sledding and building snow forts.
Sierra’s love of nature was inspired by her South African mother, who taught her how to be still and watch nature, and by her American father, who taught her to “always pay your respects to the mountain” whenever they went skiing. She hopes to pass this along to her kids.
