Ongoing CU research explores impacts, solutions after Marshall Fire

Dec. 21, 2022

The Marshall Fire spurred researchers—many of them personally affected by the fire—to pivot and apply their expertise to the aftermath. One year later, dozens of ongoing research projects continue to explore the science behind what happened that day, the widespread impacts on people, pets and the environment and how we can mitigate future catastrophes amid a changing climate.
