Climate change is more than parts per million and greenhouse gases... The people who are feeling the worst impacts of climate, their voices have got to be heard” - Robert D. Bullard, professor at Texas Southern University. From the New York Times article: Black Environmentalists Talk About Climate and Anti-Racism.
Holly Olivarez is a PhD Candidate in the Department of Environmental Studies and Institute of Arctic and Alpine Research (INSTAAR) at University of Colorado Boulder. Holly began her undergraduate studies at Central New Mexico Community College, participated in the New Mexico Alliance for Minority Participation program, and graduated with a Bachelor of Science in Earth and Planetary Sciences from University of New Mexico in 2019. Holly also participated in the Significant Opportunities for Atmospheric Research and Sciences (SOARS) program, a ten-week research internship for students from excluded groups at the University of Atmospheric Research (UCAR) in 2018, 2019, and 2023. In 2019, Holly was awarded the National Science Foundation Graduate Research Fellowship (NSF GRFP) and currently studies the marine carbon cycle.

The ocean plays a key role in the climate system. While we know of physical, biological, geological, and chemical processes occurring in the ocean, a strong understanding of the variability, both spatial and temporal, as well as underlying mechanisms in the ocean, are not well known.
I use observational records and ensembles of Earth system models (mathematical representations of the coupled physical and biogeochemical climate system) to investigate interannual to multi-decadal changes in ocean biogeochemistry in the context of internal variability over the recent past and coming century. In this work, I quantify and understand the drivers of these changes. This work is key to our interpretation of the observational record and our future projections of the global carbon cycle, both of which are reported in documents such as the Intergovernmental Panel on Climate Change (IPCC) reports.

I am very active in outreach that includes mentoring, organizing, and leadership. I use my position to not only present science to non-specialists but also to present social justice issues to students, staff, professors and administrators at CU Boulder.
From 2020 to present, I serve(d) on four campus equity and inclusion committees and consult with upper-level administrators regularly. From 2019 to 2021, I sat on 14 panels of graduate students speaking to undergraduate STEM students from excluded groups. I’ve given seven virtual presentations on “The Connection between Climate Change and COVID-19” and in 2022 I moderated two panels organized by UCAR Science Education called “Sound the Solutions: Centering Justice in Climate Change Action.”
Below is an example of a public online discussion in coordination with science educators at the National/University Center for Atmospheric Research (NCAR/UCAR):

Below is one of the climate justice panels I moderated at the invitation of UCAR SciEd:

I am also interested in talking about climate change. For example, I teamed up with an illustrator, Cal Brackin from On Board Innovations for an online discussion about art and climate communication:
