Orthographic: https://earth.nullschool.net/#2021/08/11/0100Z/chem/surface/...
Equirectangular (closely resembles Mercator): https://earth.nullschool.net/#2021/08/11/0100Z/chem/surface/...
Patterson (less distorted than Mercator): https://earth.nullschool.net/#2021/08/11/0100Z/chem/surface/...
Waterman Butterfly (minimal area distortion over land): https://earth.nullschool.net/#2021/08/11/0100Z/chem/surface/...
Winkel-Tripel (spherical variant, minimal distortion): https://earth.nullschool.net/#2021/08/11/0100Z/chem/surface/...
An equirectangular projection distorts the scale considerably at high latitudes, increasing apparent size, as does Patterson But even with non-distorted projections, the Siberian wildfires dwarf North America's.
