Here is some crucial data on Amazon fires

According to the WRI’s Fire Report for Brazil, there were 123,726 alerts in Brazil during August 15-19, 2019. WRI used NASA Fire Information for Resource Management System (FIRMS) Near Real-Time (NRT) active fire data from the MODIS and VIIRS satellites to map fire locations. The sensors on these satellites detect the heat signatures of fires from the infrared spectral band. When a fire is detected, the system indicates the area where the fire occurred with an “alert.” Because each satellite orbits the earth twice per day, these alerts can be provided in near-real time. Fire alerts are posted on the NASA FIRMS website within 3 hours of detection by the satellite.
