                         occurrence, disrupting the stability of environmental, social, and 
                         economic systems. Thus, understanding how droughts affect fire 
                         patterns in this region is essential for anticipating and planning 
                         actions for remediation of possible impacts. Focused on the 
                         Brazilian Amazon biome, we investigated fire responses to the 2010 
                         and 2015/2016 Amazonian droughts using remote sensing data. Our 
                         results revealed that the 2015/2016 drought surpassed the 2010 
                         drought in intensity and extent. During the 2010 drought, we found 
                         a maximum area of 846,800 km(2) (24% of the Brazilian Amazon 
                         biome) with significant (p <= 0.05) rainfall decrease in the first 
                         trimester, while during the 2015/2016 the maximum area reached 
                         1,702,800 km(2) (47% of the Brazilian Amazon biome) in the last 
                         trimester of 2015. On the other hand, the 2010 drought had a 
                         maximum area of 840,400 km(2) (23% of the Brazilian Amazon biome) 
                         with significant (p <= 0.05) land surface temperature increase in 
                         the first trimester, while during the 2015/2016 drought the 
                         maximum area was 2,188,800 km(2) (61% of the Brazilian Amazon 
                         biome) in the last trimester of 2015. Unlike the 2010 drought, 
                         during the 2015/2016 drought, significant positive anomalies of 
                         active fire and CO2 emissions occurred mainly during the wet 
                         season, between October 2015 and March 2016. During the 2010 
                         drought, positive active fire anomalies resulted from the 
                         simultaneous increase of burned forest, non-forest vegetation and 
                         productive lands. During the 2015/2016 drought, however, this 
                         increase was dominated by burned forests. The two analyzed 
                         droughts emitted together 0.47 Pg CO2, with 0.23 Pg CO2 in 2010, 
                         0.15 Tg CO2 in 2015 and 0.09 Tg CO2 in 2016, which represented, 
                         respectively, 209%, 136%, 82% of annual Brazil's national target 
                         for reducing carbon emissions from deforestation by 2017 
                         (approximately 0.11 Pg CO2 year(-1) from 2006 to 2017). Finally, 
                         we anticipate that the increase of fires during the droughts 
                         showed here may intensify and can become more frequent in Amazonia 
                         due to changes in climatic variability if no regulations on fire 
                         use are implemented.",
