In early July 2022, a mix of dry weather, lightning, and strange heat fueled hundreds of wildland fires in northern Canada. 136 fires had been burning in The Yukon and 65 in the Northwest Territories on July 6, per the Canadian government.
The image above used to be captured on July 6, 2022, by the Moderate Decision Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite tv for pc. Thick plumes of dense smoke billowed from several of the best fires, every so often sending smoke streaming north in direction of the Beaufort Sea and Canadian Arctic. To boot to, Ambiance Canada has posted heat and air quality warnings for several communities in the Northwest Territories.
The 2d image (below), from the Operational Land Imager (OLI) on Landsat 8, is a more in-depth stamp of fires burning near Mammoth Endure Lake, a lake in the boreal forest of Canada. Now not no longer up to 96 fires were reported in the Northwest Territories this One year, and 131,380 hectares (507 square miles, 1,313 square kilometers) hang burned. Fires in The Yukon hang charred one more 62,336 hectares (241 square miles, 623 square kilometers).

Many aspects of The Yukon and Northwest Territories hang skilled file-breaking temperatures in most fresh weeks. The intense heat dries out vegetation and makes it less difficult for fires to ignite and burn.
Be taught furthermore indicates that hot weather has made thunderstorms and lightning extra likely on this space. In a compare stamp published in 2017, scientists realized connections between temperatures, lightning strikes, fire dimension, and burned assign of abode since 1975. “We question an growing preference of thunderstorms, and ensuing from this truth fires, all around the high latitudes in the approaching a protracted time as a outcomes of local weather alternate,” stated stamp co-author Brendan Rogers of the Woodwell Local weather Be taught Heart.
Despite essential fire roar in northern Canada, Alaska, and the U.S. Southwest, overall emissions from world fire roar were low in most fresh months, per info shared by Put Parrington, an atmospheric scientist with the European Centre for Medium-Differ Weather Forecasts (ECMWF). Parrington tracks fires for the Copernicus Ambiance Monitoring Service (CAMS) the roar of a satellite tv for pc-essentially based mostly info file that began in 2003. CAMS estimates near-genuine-time wildfire emissions the roar of its International Fire Assimilation Gadget (GFAS), which aggregates observations of fires made by NASA’s Aqua and Terra satellites.
