What Are the Limits to the Growth of Boreal Fires?

ABSTRACT: Boreal forest regions, including East Siberia, have experienced elevated fire activity in recent years, leading to record-breaking greenhouse gas emissions and severe air pollution. However, our understanding of the factors that eventually halt fire spread and thus limit fire growth remains incomplete, hindering our ability to model their dynamics and predict their impacts. We investigated the locations and timing of 2.2 million fire stops-defined as 300 m unburned pixels along fire perimeters-across the vast East Siberian taiga. Fire stops were retrieved from remote sensing data covering over 27,000 individual fires that collectively burned 80 Mha between 2012 and 2022. Several geospatial datasets, including hourly fire weather data and landscape variables, were used to identify the facto
