Recent wildfire outbreaks around the world have prompted concern that climate change is
increasing fire incidence, threatening human livelihood and biodiversity, and perpetuating …

Ecologists have long studied patterns, directions and tempos of change, but there is a
pressing need to extend current understanding to empirical observations of abrupt changes …

Intensifying wildfire activity and climate change can drive rapid forest compositional shifts. In
boreal North America, black spruce shapes forest flammability and depends on fire for …

In boreal forests, climate warming is shifting the wildfire disturbance regime to more frequent
fires that burn more deeply into organic soils, releasing sequestered carbon to the …

Lightning is an indicator and a driver of climate change. Here, using satellite observations of
lightning flash rate and ERA5 reanalysis, we find that the spatial pattern of summer lightning …

Under a warming climate, degrading permafrost profoundly and extensively affects arctic
and alpine ecology. However, most existing relevant studies are more focused on the …

Boreal forest fires emit large amounts of carbon into the atmosphere primarily through the
combustion of soil organic matter,–. During each fire, a portion of this soil beneath the …

Forest fires are usually viewed within the context of a single fire season, in which weather
conditions and fuel supply can combine to create conditions favourable for fire ignition …

Thermokarst is the process whereby the thawing of ice-rich permafrost ground causes land
subsidence, resulting in development of distinctive landforms. Accelerated thermokarst due …

Extreme droughts, heat waves, frosts, precipitation, wind storms and other climate extremes
may impact the structure, composition and functioning of terrestrial ecosystems, and thus …
