Marika Holland, a climate scientist specializing in sea ice, has been awarded the prestigious John D. and Catherine T. MacArthur Foundation “genius” grant, a no-strings-attached award of $800,000 given annually to 20 individuals recognized for exceptional creativity across various disciplines. Holland, who works at the National Center for Atmospheric Research (NCAR) in Colorado, received the news this summer during a conference call, describing the moment as “completely shocking.”
Holland’s research focuses on the physics of the climate system, particularly Antarctic sea ice and its interaction with polar ecosystems. She collaborates extensively with biologists studying species such as penguins and seals, as well as engaging with Arctic communities and policymakers to better understand and respond to the impacts of climate change. Her work has increasingly highlighted the rapid declines in sea ice around Antarctica over the past decade, which threaten local ecosystems and are linked to the buildup of greenhouse gases from human activities.
“The Antarctic sea ice is critical for the region’s marine life,” Holland said. “Some of these remarkable ecosystems are at risk because of the declining sea ice, which affects species like emperor penguins throughout their breeding and molting cycles.” Her interdisciplinary approach bridges physical climate science with ecological and social dimensions, aligning with the MacArthur Foundation’s emphasis on cross-disciplinary projects.
Holland also expressed concern regarding recent political developments. Reports indicate that the Trump administration has considered dismantling NCAR, an important national center for climate research where she is employed. While the center remains operational, Holland described the potential cuts as “disheartening and shortsighted,” emphasizing the urgency of climate science amid increasing global climate-related disasters. “The models predicted these changes decades ago. Now we are living through them,” she said. “We need strong scientific institutions to help build national resilience and inform critical decisions about the future.”
Among the 20 recipients of this year’s MacArthur Fellowship, three are focused on climate-related issues. Alongside Holland, Holly Jean Buck, a sociologist at the University at Buffalo, studies emerging climate and energy policies, and Kaiyu Guan, an environmental scientist at the University of Illinois-Urbana Champaign, works on agricultural modeling to project climate impacts.
Holland said she has not yet decided how she will use the grant but hopes it will enable further collaborative work and deepen the integration of physical, biological, and social sciences to address the challenges posed by climate change.
