Accidental and intentional fires are transforming the Amazon rainforest. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on August 8, 2005, shows dozens of fires burning along roads and forest edges in Brazil. Places where MODIS detected active fires are marked with red dots.
Fires were widespread across South America on August 24, 2006, when MODIS on NASA’s Aqua satellite passed over the continent and captured this image. The sensor detected scores of active fires (locations marked in red) in a variety of ecological regions, and thick smoke hung over the land in many places.
