The Amazon has been burning for weeks amid increasing deforestation. The intense smoke was detected by NASA and plunged São Paulo into darkness on Monday.
In the middle of the day on Monday, the sky above São Paulo, Brazil went dark.
The city, along with parts of the Brazilian states of Mato Grosso and Paraná, was blanketed by smoke from wildfires raging in the Amazon, according to local news reports.
Earlier this month, Amazonas (the largest state in Brazil) declared a state of emergency over the rising number of forest fires, reported Euro News. Fire season in the Amazon is just beginning—it runs from August through October, with its peak coming in mid-September, and the smoke is already so bad that it can be seen from space
Last week, NASA released satellite images showing the patchwork of fires and smoke in Brazil. Citing the Global Fire Emissions Database, NASA noted that though current fire levels are slightly below average compared to the last 15 years, they are higher in some states, such as Amazonas and Rondônia.
“The state of Amazonas, in particular, has seen well above average daily fire activity through August so far,” said Mark Parrington, a senior scientist working on wildfire emissions at the European Center for Medium-Range Weather Forecasts.
According to Parrington, fires in the Amazon release an average of 500-600 metric tons of carbon dioxide over the course of a typical year. In 2019 so far, they’ve already released 200 metric tons of the greenhouse gas. According to the Global Fire Emissions Database, 8,668 fires have been detected in Amazonas as of Monday. That exceeds the past few years, and falls just short of the 2016 high of 8,836.
Satellite imagery has tracked the movement of the smoke, which completely filled the air in São Paulo. Gustavo Faleiros, an editor at the environmental news group InfoAmazonia, said in an email that the air quality was even worse in the countryside than in the city.
“Countryside residents started complaining about the wildfire smoke, because the air used to be clean there and now the city is full of smoke and ashes,” Alberto Shiguematsu, a São Paulo resident who tweeted about the smoke, said.
According to Shiguematsu, the sky went “really dark” around 3:15 PM yesterday. He said that in his ten years of living in São Paulo, he’s never seen wildfire smoke like that. He’d read that there were fires in the Amazon, but didn’t think he’d be affected.
“The smoke coming here, in São Paulo, thousands of kilometers away? That hit me by surprise,” he said.
