英文摘要	The 2021 North American wildfire season was marked by record breaking fire-conducive weather and widespread synchronous burning, extreme fire behaviour, smoke and evacuations. Relative to 1979-2021, the greatest number of temperature and vapor pressure deficit records were broken in 2021, and in July alone, 3.2 million hectares burned in Canada and the United States. These events were catalyzed by an intense heat dome that formed in late June over western North America that synchronized fire danger, challenging fire suppression efforts. Based on analysis of persistent positive anomalies of geopotential heights, the heat dome accounted for 21-34% of the total area burned in 2021. The event was 59% longer, 34% larger and had 6% higher maximum amplitude than the same event would have been without a warming climate. Climate change will continue to magnify heat dome events, increase fire danger, and enable extreme synchronous wildfire in forested areas of North America. Climate change effects magnified an intense heat dome over western North America leading to record breaking fire-conducive weather, widespread burning and extreme fire activity in Canada and the United States in July 2021, suggest an analysis of upper air and surface weather.
