   Wildfires continued to blaze across Central Canada in late June 2023,
   pouring rivers of smoke high into the atmosphere. The Moderate
   Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra
   satellite acquired a true-color image of the fiery scene on June 22.

   Each red “hot spot” marks an area where the thermal bands on the MODIS
   instrument detected high temperatures. When combined with smoke, as in
   this image, such hot spots mark actively burning fire. All of the fires
   in this image, except for the one farthest to the west, are burning in
   the province of Quebec. The western one is located in Ontario, near the
   border with Quebec. Given the location and quantity of dark smoke, most
   appear to be burning in boreal forests and/or in areas with peat-laden
   soils. Peat, which can be found in moist boreal ecozones, is
   exceptionally smoky when burned and is also difficult to fully
   extinguish.

   Wildfires have plagued both Western and Central Canada this spring,
   with an exceptionally early start to fire season in British Columbia
   and Alberta. By early June, a wildfire outbreak struck the province of
   Quebec. Wildfires in both locations have continued through the month of
   June. On June 23, the Society for the Protection of Forests Against
   Fire (SOPFEU) reported that 81 fires were burning in the Intensive
   Protective Zone (the area in which all fires are normally fought to
   extinguish), with 31 more in the Northern Zone. Twenty-five of the
   total fires were considered out of control. Active fires covered
   1,054,171 hectares (ha) in the IPZ and 999,152 ha in the Northern Zone.

   A large and dedicated crew of firefighters from Canada have been
   supplemented with crews from several countries, and they have made
   headway on many of the wildfires. The weather, however, has made fire
   control very difficult. On June 25, the Quebec provincial government
   warned that, “Due to low precipitation and rising temperatures,
   flammability indices vary from very high to extreme in several regions
   of Québec. These weather conditions could reinvigorate existing
   wildfires and lead to the outbreak of new fires.”
