Detailed explanation-1: -Carbon dioxide emissions from wildfires in the past two months touched a new high since 2003, from when records have been maintained. The cumulative CO2 emissions from violent forest fires in the two months was 2643.4 megatonnes, Copernicus Atmosphere Monitoring Service (CAMS) announced September 21, 2021.

Detailed explanation-2: -Yes. Wildfires release carbon dioxide (CO2) emissions and other greenhouse gases (GHG) that contribute to climate change.

Detailed explanation-3: -However, fire also impacts human health and safety, and releases greenhouse gas (GHG) emissions and other air pollutants. The GHGs emitted by fire are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Fire releases biomass carbon into the atmosphere in the form of CO2.

Detailed explanation-4: -Researchers estimated that about 127 million metric tons of carbon dioxide equivalent were released by the fires, compared with about 65 million metric tons of reductions achieved in the previous 18 years.

Detailed explanation-5: -Wildfires inject large amounts of black carbon (BC) particles into the atmosphere, which can reach the lowermost stratosphere (LMS) and cause strong radiative forcing.
