WebYes. Wildfires release carbon dioxide (CO 2) emissions and other greenhouse gases (GHG) that contribute to climate change. It is challenging to determine how much wildfire emissions alter the GHG concentrations in the atmosphere and contribute to anthropogenic climate change because wildfire emissions are part of the terrestrial carbon cycle.

Fire, Climate Change, and Carbon Cycling in the Boreal Forest
Although temperate and tropical forests in total cover twice as much land as boreal forest, boreal forest contains 20% more carbon than the other two combined. Boreal forests are susceptible to global warming because the ice/snow–albedo feedback is significantly influenced by surface temperature, so fire induced changes in surface albedo and infrared emissivity are more signifi… Web27 okt. 2024 · Boreal forests, storing approximately half of the global forest carbon (C), are key to the global C cycle and climate regulation. The sustainability of C stocks is adversely impacted by forest management. However, the economic gain–C stock relationship across forest management alternatives and diverse C pools remain unclear. … Web1 jun. 2007 · Temperate and boreal forests in the Northern Hemisphere cover an area of about 2 x 10 (7) square kilometres and act as a substantial carbon sink (0.6-0.7 petagrams of carbon per year). Although forest expansion following agricultural abandonment is certainly responsible for an important fraction of this carbon sink activity, the additional ... preetha ashokan
