The Amazon rainforest is burning at a rate unseen since scientists started tracking fires in the region in 2013.
This year, scientists have recorded more than 74,843 fires in Brazil, a figure on pace to more than double 2018's total of 40,000. It's an 83% increase in wildfires over the same timeframe last year, according to Brazil's space research center, the INPE. It has become so extreme that smoke blotted out the sun over Sao Paulo, the nation's largest city.
Around 3pm local time on Monday, the sky started to turn. The sudden darkness was caused by "the combination of wildfire smoke, dense rain clouds, and a cold front," per Accuweather. The smoke, some of which came from more than 2,000 miles away, is the result of more than 9,000 forest fires in the nation that have started since last Thursday. Many in the city began sharing videos on social media.
