Deeper Insight Into 2019 Fires From Satellite Study of Amazon Rainforest

Throughout August and early September 2019, media around the world have reported on the extensive forest fires ravaging Brazil’s Amazon rainforest. Much of the concern stems from the Amazon’s significance to regulating the world’s climate. According to the Associated Press, the Amazon absorbs 2 billion tons of carbon dioxide every year — about 5% of global emissions. Thus, fires in the region eat away at this carbon-absorbing capacity while at the same time adding carbon to the air through burning.

A recent study in the peer-reviewed journal Ecohydrology headed by University of Kansas researcher Gabriel de Oliveira gives important context to the fires burning big swaths of the Amazon today, most of which were set intentionally by farmers and ranchers to convert forest into land suitable for grazing animals or growing crops. The researchers sought to discover how these changes to land cover affect the exchange of water and heat between the surface of the Amazon and the atmosphere overhead.
