On Dec. 30, 2021, a fast-moving wildfire in suburban Boulder County became the costliest wildfire in ÃÛÌÇÖ±²¥ history. It burned 6,000 acres, destroyed more than 1,000 homes and damaged thousands of others. The Marshall Fire also spurred researchers—many personally affected by the fire—to apply their expertise to the aftermath. A year later, dozens of ongoing research projects continue to explore the science behind the fire; its widespread impacts; and how we can mitigate future catastrophes in a changing climate.
