📣🔥 New wildfire study: Blazes that cross into neighborhoods are much more deadly than remote wildfires, according to a new study led by NSF NCAR. In fact, fires that burn in the wildland-urban interface are 3x more likely to cause annual premature deaths. Learn more: bit.ly/4hhsdwZ

NSF NCAR Atmospheric Chemistry Observations & Modeling (@ncar-acom) is pleased to join the Bluesky scientific community! We look forward to exchanging information with our colleagues on scientific events, learning about recent publications, and discussing atmospheric chemistry.
