The smoke blocked out the Sun almost entirely in Sao Paulo.
According to Brazil's National Institute for Space Research (INPE), it's the worst fire season since the agency began tracking the rainforest in 2013 — with 83 percent more fires than over the same period in 2018.

To re-iterate, that's really bad: the trees of the Amazon are said to be responsible for producing 20 percent of oxygen in our planet's atmosphere.
Entire regions of the country stayed dark as massive amounts of smoke caused by the fire swept the north east. São Paulo — a city of over 12 million people thousands of miles from the Amazon — was engulfed in a black shroud most of this week, blocking out the light of the Sun almost completely.
Many of the wildfires are caused by farmers deliberately setting the land on fire to deforest land for cattle, as Reuters points out. The relaxing of environmental controls by Brazil's current leadership under president Jair Bolsonaro aren't helping the situation either.
Bolsanero fired the director of INPE earlier this month after calling the agency's findings "lies," as CNN reports.
While wildfires naturally occur in the dry season, this week's fire is on an entirely different scale.
"The dry season creates the favorable conditions for the use and spread of fire, but starting a fire is the work of humans, either deliberately or by accident,” INPE researcher Alberto Setzer told Reuters.
