Global vegetation fire emissions typically constitute a third of total releases of carbon dioxide, the main heat - trapping emission, annually (1).
During last year's round of climate treaty talks, in Lima, Peru, a statement issued by the Global Fire Monitoring Center underscored the need to address
global vegetation fires in the context of climate change, referring to the work of 58 scientists who evaluated the global state of fire between 1993 and 2014.

vegetation and soils and carbon release.

Considering forest - threatening factors such as
fires, deforestation, and the emission of greenhouse gases, the research found if the regions of the Amazon most crucial to maintaining the biome's climate are lost, large sections of the once lush rainforest may be reduced to a virtual desert.According to a report from Globo Amazônia, the study conducted by Gilvan Sampaio of National Institute of Special Research (INPE) found that the
vegetation of the Amazon will be particularly impacted by rising
global temperatures in the years to come, in addition to the continued threats posed by deforestation and
fires.
