Wildfire is a natural phenomenon that shapes ecosystems globally, interacts with the climate and threatens human communities [].As a combustion process, fire can be broadly divided into two types, flaming or smouldering [].Both are present in most wildfires, and despite being fundamentally different in chemical and physical terms, one can transition to the other []. First, newly burned areas of an overwintering fire are found near the original burn scar, and second, they require no additional ignition source and can therefore re-emerge early in the fire.

Suppression is more active below about 65 degrees N latitude, but many fires even in those areas are little affected by suppression. The spots were appearing early in the year and roughly over where fires had burned in 2019.

Abstract. The Institute of Arctic and Alpine Research conducts interdisciplinary research in earth system science and climate dynamics to better understand past, present, and future change in high-latitude, alpine, and global environments.
